117-771: Similar contests are held on the Detroit River and the St. Mary's River . The Great North River Tug Boat Race and Competition, or as it is more commonly known the New York Tug Boat Race or the Hudson River Tugboat Race, was first held in 1991. The event put on by the Intrepid Sea, Air & Space Museum and headed by Captain Jerry Roberts. The original course started 79th Street Boat Basin and ended at Pier 86 or as it

234-594: A Canadian Heritage River .   It is the only river in North America to have such dual designations. In 2001, the Wyandotte National Wildlife Refuge was absorbed into the larger Detroit River International Wildlife Refuge , a cooperative effort between the United States and Canada to preserve the area as an ecological refuge. The millions of dollars spent since that time to dredge pollutants out of

351-471: A river and a strait  — a strait being a narrow passageway connecting two large bodies of water, which is how the river earned its name from early French settlers. However, today, the Detroit River is rarely referred to as a strait, because bodies of water referred to as straits are typically much wider relative to their length. The river forms the southern portion of the waterway connecting Lake Huron to

468-488: A biological system, where ecosystems are broken up into smaller parts through land-use changes (e.g. agriculture ) and natural disturbance. This both reduces the size of the population and increases the degree of isolation. These smaller and isolated populations tend to be more vulnerable to extinction. Fragmenting ecosystems decreases the quality of the habitat. The edge of a fragment has a different range of environmental conditions and therefore supports different species than

585-551: A classical nude woman was originally installed to overlook a reflecting pool in the Grosse Pointe War Memorial . It was nicknamed "The Nude," and, in 2001, was believed to have been successfully stolen for display in some art collector's private cache. During a police diving exercise near a submerged Jeep , the statue was found in 2009, restored, and returned to the memorial. Anchors from the SS Greater Detroit,

702-611: A degraded natural ecosystem commenced in 1896, at Nairm (as it is known to people of the Kulin nation), or Port Phillip Bay, Melbourne. Local government and community groups replanted degraded areas of the foreshore reserves with the indigenous plant species, coastal teatree ( Leptospermum laevigatum ). The projects were motivated by utilitarian considerations: to conserve recreation sites, and promote tourism. However, some local residents, including Australian journalist, nature writer and amateur ornithologist, Donald Macdonald , were distressed at

819-400: A desired successional pathway may be difficult if multiple stable states exist. Looking over 40 years of wetland restoration data, Klötzli and Gootjans (2001) argue that unexpected and undesired vegetation assemblies "may indicate that environmental conditions are not suitable for target communities". Succession may move in unpredicted directions, but constricting environmental conditions within

936-658: A diverse international group of restoration scientists and practitioners. The second edition builds on the first edition of the Standards, which was released December 12, 2016, at the Convention on Biological Diversity 's 13th Conference of the Parties in Cancun, Mexico. The development of these Standards has been broadly consultative. The first edition was circulated to dozens of practitioners and experts for feedback and review. After release of

1053-608: A luxury steamship that toured the Detroit River from 1924 to 1950, and the famed SS Edmund Fitzgerald , a lake freighter that sank in a terrible 1975 storm, have notably both been recovered from the river. The 6,000-pound anchor of the SS Greater Detroit was raised in November 2016. It was installed at the Detroit/Wayne County Port Authority Building. The lost anchor of the SS Edmund Fitzgerald

1170-590: A means to reduce the presence of invasive species and limit their spread. As this approach emphasizes the control of invaders, the restoration techniques can differ from typical restoration projects. The goal of such projects is not necessarily to restore an entire ecosystem or habitat. These projects frequently use lower diversity mixes of aggressive native species seeded at high density. They are not always actively managed following seeding. The target areas for this type of restoration are those which are heavily dominated by invasive species. The goals are to first remove

1287-688: A narrow range may rein in the possible successional trajectories and increase the likelihood of the desired outcome. A study quantified climate change mitigation potentials of 'high-income' nations shifting diets – away from meat-consumption – and restoration of the spared land. They find that the hypothetical dietary change "could reduce annual agricultural production emissions of high-income nations' diets by 61% while sequestering as much as 98.3 (55.6–143.7) GtCO 2 equivalent, equal to approximately 14 years of current global agricultural emissions until natural vegetation matures", outcomes they call "double climate dividend". For most restoration projects it

1404-649: A range of factors. Targets are set based on factors such as the level of ecosystem degredation, how much ecosystem functionality can realistically be restored, local community views, and the costs of restoration efforts. There are many reasons to restore ecosystems. Some include: There are considerable differences of opinion on how to set restoration goals and define their success. As Laura J. Martin writes, "Restoration targets are moral and political matters as well as logistical and scientific ones." Some restorationists urge active restoration (e.g. killing invasive animals) and others believe that protected areas should have

1521-408: A restoration project. Spatial heterogeneity of resources can influence plant community composition, diversity, and assembly trajectory. Baer et al. (2005) manipulated soil resource heterogeneity in a tallgrass prairie restoration project. They found increasing resource heterogeneity, which on its own was insufficient to ensure species diversity in situations where one species may dominate across

1638-504: A restoration site that is closer to remaining vegetation will be more likely to be naturally regenerated through seed disperal than a site that is further away. Ecosystem function describes the most basic and essential foundational processes of any natural systems, including nutrient cycles and energy fluxes . An understanding of the complexity of these ecosystem functions is necessary to address any ecological processes that may be degraded. Ecosystem functions are emergent properties of

1755-580: A separate field in ecology in the late twentieth century. The term was coined by John Aber and William Jordan III when they were at the University of Wisconsin–Madison . In 2024, the European Union passed a nature restoration law aiming to restore 20% of degraded ecosystems by 2030 and 100% by 2050. The representative of Austria, Leonore Gewessler , voted against the will of its government and can face up to 10 years in prison for doing so. Prior to

1872-1032: A single conceptual umbrella". Community assembly theory attempts to explain the existence of environmentally similar sites with differing assemblages of species. It assumes that species have similar niche requirements, so that community formation is a product of random fluctuations from a common species pool . Essentially, if all species are fairly ecologically equivalent, then random variation in colonization, and migration and extinction rates between species, drive differences in species composition between sites with comparable environmental conditions. Genetic diversity has shown to be as important as species diversity for restoring ecosystem processes. Hence ecological restorations are increasingly factoring genetic processes into management practices. Population genetic processes that are important to consider in restored populations include founder effects , inbreeding depression , outbreeding depression , genetic drift , maladaption and gene flow . Such processes can predict whether or not

1989-544: A species successfully establishes at a restoration site. Leaf litter accumulation plays an important role in the restoration process. Higher quantities of leaf litter hold higher humidity levels, a key factor for the establishment of plants. The process of accumulation depends on factors like wind and species composition of the forest. The leaf litter found in primary forests is more abundant, deeper, and holds more humidity than in secondary forests. These technical considerations are important to take into account when planning

2106-508: A variety of strategies employed at different restoration sites to better understand the most successful management techniques to control invasion. To develop restoration ecology into a full science and to improve its practice requires generalizations about the processes governing the development of restored communities. While new experiments can be designed, one way forward is to use data from existing restoration studies to relate plant species performance to their ecological trait. Progress along

2223-423: A viable ecosystem restoration strategy, especially in countries with large agriculture footprints. Climate benefits from nature restoration are "dwarfed by the scale of ongoing fossil fuel emissions ". It risks "over-relying on land for mitigation at the expense of phasing out fossil fuels". Despite these issues, nature restoration is receiving increasing attention, with a study concluding that "Land restoration

2340-418: Is a driver of environmental degradation . However it is vital that ecosystem restoration efforts do not clash with increasing needs for food production. Restoration frameworks aim to assist policy decisions by minimizing trade-offs between ecological restoration and production and evaluating the best use of land to balance carbon storage and food growing. For example, agroforestry is increasing considered as

2457-1070: Is also known the Intrepid Pier. The Intrepid Museum held the event for its first 13 years. Captain Jerry Roberts left the Intrepid Museum staff after the 2004 event. Sponsors, co-sponsors and contributors to the event have included Hudson River Park Trust, Friends of Hudson River Park, New York City Department of Environmental Protection , Circle Line Sightseeing Cruises , NYC Economic Development Corporation, Reinauer Transportation, McAllister Towing, Miller’s Tugs & Barge, Kirby Offshore Marine Metropolitan Marine Transportation, Bren Transportation, Vane Brothers, P.D.

2574-652: Is an international river in North America . The river, which forms part of the border between the U.S. state of Michigan and the Canadian province of Ontario , flows west and south for 24 nautical miles (44 km; 28 mi) from Lake St. Clair to Lake Erie as a strait in the Great Lakes system. The river divides the metropolitan areas of Detroit , Michigan , and Windsor , Ontario —an area collectively referred to as Detroit–Windsor . The Ambassador Bridge ,

2691-410: Is an important option for tackling climate change but cannot compensate for delays in reducing fossil fuel emissions" as it is "unlikely to be done quickly enough to notably reduce the global peak temperatures expected in the next few decades". Researchers have found that, in terms of environmental services, it is better to avoid deforestation than to allow for deforestation to subsequently reforest, as

2808-480: Is controversial and sometimes critiqued as carbon colonialism. Another driver of restoration projects in the United States is the legal framework of the Clean Water Act , which often requires mitigation for damage inflicted on aquatic systems by development or other activities. Ecological restoration draws on a wide range of ecological concepts. Disturbance is a change in environmental conditions that disrupt

2925-551: Is essential to understand the life cycles and interactions of species, as well as the essential elements such as food, water, nutrients, space, and shelter needed to support species populations. Scientists estimate that the current species extinction rate, or the rate of the Holocene extinction , is 1,000 to 10,000 times higher than the normal, background rate. Habitat loss is a leading cause of species extinctions and ecosystem service decline. Two methods have been identified to slow

3042-562: Is estimated walleye fishing alone brings in $ 1 million to the economy of communities along the lower Detroit River each spring. Other fish caught by recreational fisherman include white bass , bluegill , crappie , freshwater drum , smallmouth bass , northern pike and muskie . There are over 800,000 recreation boats in Michigan, and more than half of them are regularly used on or near the Detroit River. Popular river destinations in Detroit include

3159-553: Is four times longer than the Detroit River and contains most of the watershed. The only other major American tributary to the Detroit River is the much smaller Ecorse River . Tributaries on the Canadian side include Little River, Turkey Creek, and the River Canard . The discharge for the Detroit River is relatively high for a river of its size. The river's discharge averaged over the year is 5,300 m /s (190,000 cu ft/s), and

3276-593: Is generally recommended to source material from local populations, to increase the chance of restoration success and minimize the effects of maladaptation . However the definition of local can vary based on species, habitat and region. US Forest Service recently developed provisional seed zones based on a combination of minimum winter temperature zones, aridity, and the Level III ecoregions. Rather than putting strict distance recommendations, other guidelines recommend sourcing seeds to match similar environmental conditions that

3393-845: Is important for protecting biodiversity. However, conservation biology is primarily rooted in population biology . Because of that, it is generally organized at the population genetic level and assesses specific species populations (i.e. endangered species ). Restoration ecology is organized at the community level, which focuses on broader groups within ecosystems. In addition, conservation biology often concentrates on vertebrate and invertebrate animals because of their salience and popularity, whereas restoration ecology concentrates on plants . Restoration ecology focuses on plants because restoration projects typically begin by establishing plant communities. Ecological restoration, despite being focused on plants, may also have " umbrella species " for individual ecosystems and restoration projects. For example,

3510-548: Is important if we are to understand how to restore natural processes and minimize anthropogenic impacts on the ecosystems. Ecological succession is the process by which a community changes over time, especially following a disturbance. In many instances, an ecosystem will change from a simple level of organization with a few dominant pioneer species to an increasingly complex community with many interdependent species. Restoration often consists of initiating, assisting, or accelerating ecological successional processes, depending on

3627-440: Is not addressed, and that the time-scales set out for 'complete' restoration are unreasonably short, while other critical markers for full-scale restoration are either ignored or abridged due to feasibility concerns. In other instances an ecosystem may be so degraded that abandonment (allowing a severely degraded ecosystem to recover on its own) may be the wisest option. Local communities sometimes object to restorations that include

3744-476: Is not always a sustainable solution long term without additional weed control, such as mowing, or re-seeding. Restoration projects are also used as a way to better understand what makes an ecological community resistant to invasion. As restoration projects have a broad range of implementation strategies and methods used to control invasive species, they can be used by ecologists to test theories about invasion. Restoration projects have been used to understand how

3861-515: Is on the banks of the Detroit River. According to a 2004 study, 150,000 jobs and $ 13 billion in annual production depend on the river crossings connecting Detroit to Windsor. In 2004, the American trade with Ontario alone was $ 407 billion, in which 28% ($ 113.3 billion) crossed the Detroit River. There are two automobile traffic routes that completely cross the river: the Detroit–Windsor tunnel and

3978-476: Is relatively level, dropping only 3 feet (0.9 m) before entering Lake Erie at 571 feet (174 m). As the river contains no dams and no locks , it is easily navigable by even the smallest of vessels. The watershed basin for the Detroit River is approximately 700 square miles (1,800 km ). Since the river is fairly short, it has few tributaries, the largest being the River Rouge in Michigan; this

4095-593: The Detroit International Riverfront and Belle Isle Park  — both of which host events throughout the year. Several restaurants on the river have docks for boaters. Tour boats and dinner cruises travel through the sights of Detroit and the undeveloped islands downriver. Cruise ships support tourism on the Great Lakes and dock at the Port Detroit passenger terminal downtown. The iconic Renaissance Center

4212-730: The Detroit–Windsor Tunnel , and the Michigan Central Railway Tunnel connect the cities. The river's English name comes from the French Rivière du Détroit (translated as "River of the Strait"). The Detroit River has served an important role in the history of Detroit and Windsor, and is one of the world's busiest waterways. It is an important transportation route connecting Lake Michigan , Lake Huron , and Lake Superior to Lake Erie and eventually to Lake Ontario ,

4329-461: The Monarch butterfly is an umbrella species for conserving and restoring milkweed plant habitat, because Monarch butterflies require milkweed plants to reproduce. Finally, restoration ecology has a stronger focus on soils , soil structure , fungi , and microorganisms because soils provide the foundation of functional terrestrial ecosystems. The Society for Ecological Restoration (SER) released

4446-473: The North American fur trade intensified, European settlers expanded their trade westward into uncharted territories. French explorer Antoine Laumet de La Mothe, sieur de Cadillac sailed up the Detroit River on July 23, 1701. The next day, he established Fort Pontchartrain du Détroit , which developed as Detroit. The French named the river as Rivière Détroit . Détroit is French for " strait ". The river

4563-500: The St. Lawrence Seaway and the Erie Canal . When Detroit underwent rapid industrialization at the turn of the 20th century, the Detroit River became notoriously polluted and toxic. Since the late 20th century, however, a vast restoration effort has been undertaken because of the river's ecological importance. In the early 21st century, the river today has a wide variety of economic and recreational uses. There are numerous islands in

4680-632: The St. Lawrence Seaway or the Erie Canal to New York City . At the beginning of the 20th century, the automotive industry boomed, and the many manufacturers imported abundant supplies of iron ore , sand, limestone and wood. The Detroit River provides substantial revenue for the local economies. A 1991 study showed $ 20.1 million came from sales related to waterfowl hunting along the Detroit River. The same year, bird watching, photography, and other non-consumptive uses of waterfowl contributed another $ 192.8 million to Michigan's economy. Local economies benefit through boating registrations and fishing licenses. It

A completely self-perpetuating and fully functional ecosystem is the ultimate goal of restorative efforts. We must understand what ecosystem properties influence others to restore desired functions and reach this goal. Community assembly "is a framework that can unify virtually all of (community) ecology under

5382-526: The British colonial government in Canada declared former slaves could not be extradited to be returned to their owners. With their freedom in Canada secured, crossing the Detroit River out of the United States became an imperative for escaping slaves. During the American Civil War (1861–1865), the Union feared the seceded Confederate States of America (CSA) would plan a northerly attack from Canada, which

5499-459: The Broken Hill regeneration area project. This project involved the natural regeneration of indigenous flora on a severely wind eroded site of hundreds of hectares, located in arid western New South Wales. Local and state governments, and the Broken Hill mining industry, supported and funded the project. In fact, as the regeneration area project was so well adapted to the harsh arid-zone conditions,

5616-541: The Canadian border region also assisted Blacks hoping to flee from the U.S. once the Fugitive Slave Act was strengthened in 1850. Canada also granted legal immigration status to Blacks, while Mexico did not for many years. Individuals and organizations assisted escaping slaves hoping to cross the Detroit River from the United States into Canada. The Second Baptist Church of Detroit and First Baptist Church of Amherstburg coordinated ferrying thousands of Blacks across

The portion of the river in the city of Detroit has been organized into the Detroit International Riverfront and the William G. Milliken State Park and Harbor . The Detroit River is designated both an American Heritage River and a Canadian Heritage River —the only river to have this dual designation. The Detroit River flows for 28  mi (45  km ) from Lake St. Clair to Lake Erie . By definition, this classifies it as both

5850-412: The Detroit River but the term "Downriver" refers broadly to the cluster of 18 suburban communities that lie to the southwest of the city of Detroit and to the west of the Detroit River. The Detroit River contains 31 charted islands. The majority of the islands are located on the American side of the river. Many of the islands are small and uninhabited, and none are divided by the international border, as

5967-470: The Detroit River has led to a remarkable restoration, although problems remain. Today, many species of native animals that had been driven out by human development are returning to the area. The river is home to a growing number of bird species such as eagles (including reintroduced bald eagles ), ospreys , and peregrine falcons . Large numbers of lake whitefish , sturgeon , silver bass , black bass , salmon , perch , and walleye are again thriving in

Famous abolitionists and Underground Railroad conductors including George DeBaptiste and William Lambert worked individually and with these organizations to assist fleeing slaves and condemn slavery.   There was considerable transnational fluidity between the Canadian and American sides of

6201-409: The Detroit River is urbanized and, in some places, has been used for industrial purposes for more than 100 years. There has been excessive water pollution of the river from the long-term, unregulated dumping of chemicals, industrial waste, garbage, and sewage. Much of the Detroit River and its shoreline were polluted and unsafe for recreational use. Thousands of migrating birds died each year because of

6318-491: The Detroit River, and Lake Erie. Finally, a massive conservation effort was initiated to clean up the Detroit River. For years, the multi-million dollar cost of removing pollutants from the river and the political influence of nearby industries, hindered conservation efforts. In 1998, the Detroit River was designated as an American Heritage River by the US Environmental Protection Agency and in 2001 as

6435-507: The Detroit River. The French later claimed the area for New France . The famed sailing ship Le Griffon reached the mouth of the Detroit River in mid-August 1679 on its maiden voyage through the Great Lakes . Later, when the French began settling in the area, they navigated the river using canoes made of birch or elm bark. Handcrafted vessels were a common mode of travel across the river, and pirogues and bateaux were also used. As

6552-555: The Hudson River and the port of New York City, the Detroit River became a route for many migrating settlers traveling to northern Michigan. Detroit rapidly attracted a share of new residents. Following the Patriot War , in which British regulars and Michigan militia nearly came to armed conflict on the ice-covered Detroit River, the United States built Fort Wayne at Detroit to counter Britain's riverside Fort Malden at Amherstburg across

6669-496: The New South Wales state government adopted it as a model for the proposed restoration of the twenty million hectares of the arid western portion of the state that had been reduced to a severely eroded condition. Legislation to this effect was passed in 1949. Another significant early Australian settler ecological restoration project occurred on the north coast of New South Wales. From approximately 1840 settlers forcibly occupied

6786-467: The United States. Environmental restoration Ecological restoration , or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed or transformed. It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures. Ecological restoration can reverse biodiversity loss, combat climate change , support

6903-447: The aim has been to return ecosystems to a past state (historic baseline), based on the idea that past conditions represent a 'pristine' or ideal functioning state. However, this approach is now questioned because human-driven environmental changes, including climate change, continuously alter ecosystems, resulting in a shifting baseline . Today, it’s widely recognized that there may be several possible targets for restoration, based on

7020-415: The aim of the restoration, or an incomplete understanding of the underlying ecological framework lead to insufficient measures. This may be because, as Peter Alpert says, "people may not [always] know how to manage natural systems effectively". Furthermore, many assumptions are made about myths of restoration such as carbon copy , where a restoration plan, which worked in one area, is applied to another with

7137-466: The bare minimum of human interference, such as rewilding . Skeptics doubt that the benefits justify the economic investment or point to failed restoration projects and question the feasibility of restoration altogether. It can be difficult to set restoration goals because, as Anthony Bradshaw writes, "ecosystems are not static, but in a state of dynamic equilibrium." Some scientists argue that, though an ecosystem may not be returned to its original state,

The only other location where this occurs is Fort Erie, Ontario , which lies south of several cities in Niagara County, New York . The cities and communities southwest of Detroit along the American side of the river are popularly referred to as the Downriver area, because those areas are said to be "down the river" from Detroit. Several of these communities do not border

7605-497: The coastal hinterlands, dispossessed First Nations communities, destroyed extensive areas of biologically diverse rainforest and converted the land to farms. Only small patches of rainforest survived. In 1935 dairy farmer Ambrose Crawford began restoring a degraded four acre (1.7 hectare) patch of local rainforest, or "Big Scrub" (Lowland Tropical Rainforest), as it was referred to, at Lumley Park reserve, Alstonville. His main restoration techniques were clearing weeds that were smothering

7722-466: The data. Managers vary in how much data they collect, and how many records they keep. Some agencies keep only a handful of physical copies of data that make it difficult for the researcher to access. Many restoration projects are limited by time and money, so data collection and record-keeping are not always feasible. However, this limits the ability of scientists to analyze restoration projects and give recommendations based on empirical data. Agriculture

7839-590: The development of International Principles & Standards for the Practice of Ecological Restoration by the Society for Ecological restoration (see below) – however, this approach is contended, with scientists active in the field suggesting that this is restrictive, and instead principles and guidelines offer flexibility. There is further complication in that restoration ecologists who want to collect large-scale data on restoration projects can face enormous hurdles in obtaining

7956-472: The diversity of the species introduced in the restoration affects invasion. We know that generally higher diversity prairies have lower levels of invasion. The incorporation of functional ecology has shown that more functionally diverse restorations have lower levels of invasion. Furthermore, studies have shown that using native species functionally similar to invasive species are better able to compete with invasive species. Restoration ecologists have also used

8073-615: The dramatic increase in the number of protected natural areas in the 1980s. In 1997 the National Wildlife Federation signed a memorandum of understanding with the Intertribal Bison Cooperative, the first-ever conservation agreement between an environmental organization and an inter-tribal group, to advocate for the restoration of wild bison to tribal lands. Anishinaabek/Neshnabék throughout the Great Lakes region are leading ecological restoration projects that, in

8190-576: The emergence of ecology as a scientific discipline, large-scale restoration began with big game restoration in the early 20th century. The first native plant restoration project in the United States was established in 1907 by Eloise Butler in Minneapolis, Minnesota. This was followed by the Vassar College Ecological Laboratory restoration program, founded by Professor Edith Roberts in 1921. The first tallgrass prairie restoration

Restoration ecology emerged as

8424-686: The forced dispossession of the First Nations communities of Australia. The substantial Traditional Ecological Knowledge of First Nations communities was not utilised in the historical restoration projects. Many of the first Australian settler restoration projects were initiated by volunteers, often in the form of community groups. Many of these volunteers appreciated and utilised science resources, such as botanical and ecological knowledge. Local and state government agencies participated, and also industry. Australian scientists came to play an increasingly important role. A prominent scientist who took an interest in

8541-414: The former leads to irreversible effects in terms of biodiversity loss and soil degradation . Furthermore, the probability that legacy carbon will be released from soil is higher in younger boreal forest. Global greenhouse gas emissions caused by damage to tropical rainforests may have been substantially underestimated until around 2019. Additionally, the effects of af- or reforestation will be farther in

Rum-running in Windsor and production of bootleg liquor became common practices. American mobsters such as the Purple Gang of Detroit used violence to control the route known as the "Detroit-Windsor Funnel," and continue to gain lucrative returns from

8775-417: The functioning of an ecosystem. Disturbance can occur at a variety of spatial and temporal scales, and is a natural component of many communities. For example, many forest and grassland restorations implement fire as a natural disturbance regime . However the severity and scope of anthropogenic impact has grown in the last few centuries. Differentiating between human-caused and naturally occurring disturbances

8892-476: The functions of a " novel ecosystem " are still valuable. Ecosystem restoration can mitigate climate change through activities such as afforestation . However, afforestation can have negative impacts on biodiversity especially when considering tree-planting initiatives in tropical savannas . The impacts of afforestation on water supply and quality are also debated and vary by region, climate and age of afforestation projects. Forestry-based carbon offsetting

9009-531: The future than keeping existing forests intact. It takes much longer − several decades − for the benefits for global warming to manifest to the same carbon sequestration benefits from mature trees in tropical forests and hence from limiting deforestation. Therefore, scientists consider "the protection and recovery of carbon-rich and long-lived ecosystems, especially natural forests" to be "the major climate solution ". Both restoration ecologists and conservation biologists agree that protecting and restoring habitat

9126-413: The government's placing tighter restrictions on industries; substantial government funding at various levels has been allocated to clean up the river. In this early period, opponents believed that such efforts would adversely affect Detroit's industry and economy. In 1970, toxic levels of mercury in the water resulted in the total closing of the fishing industry in the St. Clair River , Lake St. Clair ,

9243-489: The indigenous vegetation. It was also found that furrowing (or ploughing) of eroded areas resulted in the natural regeneration of indigenous vegetation. So successful were these programs that the South Australian government adopted them as approved state soil conservation policies in 1936. Legislation introduced in 1939 codified these policies. In 1936 mining assayer Albert Morris and his restoration colleagues initiated

9360-406: The interior. Restorative projects can increase the effective size of a population by adding suitable habitat and decrease isolation by creating habitat corridors that link isolated fragments. Reversing the effects of fragmentation is an important component of restoration ecology. The composition of the surrounding landscape can also influence the effectiveness of restoration projects. For example,

9477-527: The introduction of large predators or plants that require disturbance regimes such as regular fires, citing threat to human habitation in the area. High economic costs can also be perceived as a negative impact of the restoration process. Public opinion is very important in the feasibility of a restoration; if the public believes that the costs of restoration outweigh the benefits they will not support it. Many failures have occurred in past restoration projects, many times because clear goals were not set out as

9594-586: The loss of valued biological qualities, and campaigned to fully restore the Teatree ecosystems and conserve them and their indigenous fauna. The degraded arid-zone regions of Australia were the site of historical ecological restoration projects. Pastoral industry established in the arid-zone regions of South Australia and New South Wales resulted in the substantial degradation of these areas by ca.1900 resulting in severe wind erosion. From approximately 1930, Australian pastoralists implemented revegetation projects aiming to

9711-457: The north and Lake Erie to the south, with other portions including the St. Clair River and Lake St. Clair . The Detroit River is only 0.5–2.5 miles (0.8–4.0 km) wide. It begins with an east-to-west flow from Lake St. Clair, but curves and runs north to south. The deepest portion of the Detroit River is 53 feet (16.2 m) in its northern portion. At its source, the river is at an elevation of 574 feet (175 m) above sea level. The river

9828-412: The oil slicks and contaminated water around the mouth of the Detroit River at Lake Erie . The river's oxygen levels were depleted to the point where fish could not inhabit its waters. Because this pollution often drained into and affected Lake Erie, the lake was considered "dead" and unable to support aquatic life. In 1961, a congressional order founded the Wyandotte National Wildlife Refuge. That began

9945-473: The privately owned Ambassador Bridge , both of which connect Detroit, Michigan, to Windsor, Ontario. A railway tunnel and a commercial truck ferry service also travel between Detroit and Windsor. In Michigan, there are two bridges connecting the mainland to Grosse Ile , as well as the MacArthur Bridge that connects the mainland Detroit to Belle Isle . All ports of entry on the American side are secured by

10062-472: The provision of ecosystem services and support local economies. The United Nations has named 2021-2030 the Decade on Ecosystem Restoration. Habitat restoration involves the deliberate rehabilitation of a specific area to reestablish a functional ecosystem. This may differ from historical baselines (the ecosystem's original condition at a particular point in time). To achieve successful habitat restoration, it

10179-455: The rainforest plants and planting of suitable indigenous rainforest species. Crawford utilised professional government botanists as advisors, and received support from his local government council. The restored rainforest reserve still exists today. The UK Natural Capital Committee (NCC) made a recommendation in its second State of Natural Capital report published in March 2014 that in order to meet

10296-458: The range of resource levels. Their findings were consistent with the theory regarding the role of ecological filters on community assembly. The establishment of a single species, best adapted to the physical and biological conditions can play an inordinately important role in determining the community structure. Restoration is used as a tool for reducing the spread of invasive plant species many ways. The first method views restoration primarily as

10413-624: The rate of species extinction and ecosystem service decline: conservation of quality habitat and restoration of degraded habitat. The number and size of ecological restoration projects have increased exponentially in recent years. Restoration goals reflect political choices, and differ by place and culture. On a global level, the concept of nature-positive has emerged as a societal goal to achieve full nature recovery by 2050, including through restoration of degraded ecosystems to reverse biodiversity loss . The Society for Ecological Restoration defines restoration as "the process of assisting

10530-429: The recovery of an ecosystem that has been degraded, damaged, or destroyed." Restoration ecology is the academic study of the science of restoration, whereas ecological restoration is the implementation by practitioners. Ecological restoration includes a wide diversity of methods including erosion control, reforestation , removal of non-native species and weeds, revegetation of disturbed areas, daylighting streams ,

10647-408: The reintroduction of native species , habitat and range improvement for targeted species and establishing wildlife corridors . Many scholars and practitioners argue that ecological restoration must include local communities and stakeholders: they call this process the "social-ecological restoration". The goal of ecosystem restoration depends on the specific context of each location. Traditionally,

10764-478: The reversal of vegetation degradation was botanist and plant ecologist Professor T G Osborn , University of Adelaide, who, in the 1920s, conducted pioneering research into the causes of arid-zone indigenous vegetation degradation. From this time, Australian botanists, plant ecologists and soil erosion researchers have increasingly developed interests in the recovery of ecological functioning on degraded sites. The earliest known attempt by Australian settlers to restore

10881-491: The river lives in Michigan . The Detroit River has two automobile traffic crossings connecting the United States and Canada: the Ambassador Bridge and the Detroit–Windsor Tunnel . Both of these are strongly protected by the U.S. Customs and Border Protection and the Canada Border Services Agency . The upper portion of the river is one of the two places where a Canadian city lies directly south of an American city. In this case,

10998-470: The river until the middle of the 19th century. The 1833 Blackburn Riots in Detroit, which erupted after slave hunters detained couple Lucie and Thornton Blackburn, marked the end of hundreds of years of a nearly porous border between Canada and the United States on the Detroit River. Detroit's African American population protested and helped the Blackburns escape across the Detroit River to Upper Canada, where

11115-407: The river's flow is relatively constant. The Detroit River forms a major element of the international border between the United States and Canada. The river on the American side is all under the jurisdiction of Wayne County, Michigan , and the Canadian side is under the administration of Essex County, Ontario . The largest city along the Detroit River is Detroit , and most of the population along

11232-527: The river. The Detroit River and its recovery efforts were listed as a Michigan State Historic Site in 2007. A historic marker was erected along the river in a park that now serves as the Detroit River International Wildlife Refuge visitor center in the city of Trenton . The Detroit River is used for shipping and trading. The earliest use of the river for these economic activities was the shipping of furs for trade as early as

11349-572: The river. The Detroit River served as a final stop on the Underground Railroad and was the most active entry point along the United States–Canada border for fugitive slaves. Escaping slaves often chose to cross through the Detroit River rather than flee to Mexico because of the river's location near free states made it less risky than traveling through slaveholding states that border Mexico. The strong Underground Railroad networks in

11466-416: The river. Inventory documents record a total of 17 cannons and 14 have been accounted for. It is believed that the British dragged the cannons onto the frozen river so they would sink with the spring thaw, and be kept from use by the American enemy. Another seven, larger cannons may have fallen off a barge closer to Amherstburg , Ontario , and may yet be found in the river. Much of the land that surrounds

11583-405: The same results expected, but not realized. One of the struggles for both fields is a divide between restoration ecology and ecological restoration in practice. Many restoration practitioners as well as scientists feel that science is not being adequately incorporated into ecological restoration projects. In a 2009 survey of practitioners and scientists, the "science-practice gap" was listed as

11700-495: The scope of a problem in-depth, without providing concrete solutions. Additionally many restoration ecology studies are carried out under controlled conditions and frequently at scales much smaller than actual restorations. Whether or not these patterns hold true in an applied context is often unknown. There is evidence that these small-scale experiments inflate type II error rates and differ from ecological patterns in actual restorations. One approach to addressing this gap has been

11817-543: The second edition of the International Standards for the Practice of Ecological Restoration on September 27, 2019, in Cape Town, South Africa, at SER's 8th World Conference on Ecological Restoration. The publication provides updated and expanded guidance on the practice of ecological restoration, clarifies the breadth of ecological restoration and allied environmental repair activities, and includes ideas and input from

11934-429: The second most commonly cited reason limiting the growth of both science and practice of restoration. There are a variety of theories about the cause of this gap. However, it has been well established that one of the main issues is that the questions studied by restoration ecologists are frequently not found useful or easily applicable by land managers. For instance, many publications in restoration ecology characterize

12051-497: The severity of the disturbance. Following mild to moderate natural and anthropogenic disturbances, restoration in these systems involves hastening natural successional trajectories through careful management. However, in a system that has experienced a more severe disturbance (such as in urban ecosystems), restoration may require intensive efforts to recreate environmental conditions that favor natural successional processes. Habitat fragmentation describes spatial discontinuities in

12168-437: The species and then in so doing, reduce the number of invasive seeds being spread to surrounding areas. An example of this is through the use of biological control agents (such as herbivorous insects) which suppress invasive weed species while restoration practitioners concurrently seed in native plant species that take advantage of the freed resources. These approaches have been shown to be effective in reducing weeds, although it

12285-711: The species is exposed to, either now, or under projected climate change. For example, sourcing for Castilleja levisecta found that farther source populations that matched similar environmental variables were better suited for the restoration project than closer source populations. Similarly, a suite of new methods are surveying gene-environment interactions in order to identify the optimum source populations based on genetic adaptation to environmental conditions. Some view ecosystem restoration as impractical, partially because restorations often fall short of their goals. Hilderbrand et al. point out that many times uncertainty (about ecosystem functions, species relationships, and such)

12402-482: The study of techniques like prescribed burning . It was followed by the 40-hectare Schulenberg Prairie at the Morton Arboretum , initiated in 1962 by Ray Schulenberg and Robert Betz. Betz then worked with The Nature Conservancy to establish the 260-hectare Fermi National Laboratory tallgrass prairie in 1974. Restoration ecology emerged as a distinct sub-discipline of ecology and natural resources management with

12519-529: The substantial to full restoration of indigenous flora to degraded, wind eroded areas. At his arid-zone Koonamore research station in South Australia, established in 1925, Professor T G Osborn studied the loss of indigenous vegetation caused by overstocking and the resultant wind erosion and degradation, concluding that restoration of the indigenous saltbushes ( Atriplex spp.), bluebushes ( Maireana spp.) and mulga ( Acacia aneura ) vegetation communities

12636-495: The trade. The name parodied the newly built tunnel between the cities and nations. The Detroit River, Lake St. Clair , and the St. Clair River are estimated to have carried 75% of all liquor smuggled into the United States during Prohibition. Government officials were unable or unwilling to deter the flow. The rum-running industry died when prohibition was repealed in 1933 by the Twenty-first Amendment . Because of

12753-462: The two countries do not share a land border along the river. Grosse Ile is the largest and most populated of all islands, and Fighting Island is the largest Canadian island. Most islands are located in the southern portion of the river. Europeans first recorded navigating the Detroit River in the 17th century. The Iroquois traded furs with the Dutch colonists at New Amsterdam by traveling through

12870-458: The words of Kyle Whyte, "seek to learn from, adapt, and put into practice local human and nonhuman relationships and stories at the convergence of deep Anishinaabe history and the disruptiveness of industrial settler campaigns." Australia has been the site of historically significant ecological restoration projects, commencing in the 1930s. These projects were responses to the extensive environmental damage inflicted by colonising settlers, following

12987-459: The world. By comparison, London shipped 18,727,230 tons (16 billion kg), and New York shipped 20,390,953 tons (18 billion kg). From 1920 to 1933, the United States (US) enforced the Prohibition era . The sale, manufacture, and transportation of alcohol for consumption were nationally banned. Detroit, as the largest city bordering Canada, where alcohol remained legal during Prohibition, became

13104-566: Was controlled by the British Empire and remained neutral in the war. The Union feared the CSA would cross the Detroit River to launch this attack. For that reason, Union forces regularly patrolled the Detroit River and the fortification at Fort Wayne improved, although it was far removed from any major combat. A Confederate plot to capture the U.S. Navy warship, USS Michigan , and liberate Confederate prisoners from Johnson Island , in western Lake Erie,

13221-657: Was known literally as the "River of the Strait". When Great Britain defeated the French in the Seven Years' War (known as the French and Indian War on the American front), it took over control of the Detroit River, as well as other French territory east of the Mississippi River. The newly formed United States claimed this territory during the American Revolution , but the British did not transfer it until 1796. During

13338-593: Was narrowly averted only after the Confederates had captured two passenger steamships. At the beginning of the 20th century, Detroit's industrialization took off on an unprecedented scale. The Detroit River became the world's busiest commercial river and in 1908 was dubbed "the Greatest Commercial Artery on Earth" by The Detroit News . In 1907, the Detroit River carried 67,292,504 tons (61 billion kg) of shipping commerce through Detroit to markets all over

13455-432: Was possible, if a stock exclosure and natural regeneration revegetation technique was applied to degraded paddocks. Most likely influenced by Osborn's research, throughout the 1930s South Australian pastoralists adopted this revegetation technique. For example, at Wirraminna station (or property, ranch), following fencing to exclude stock, severe soil-drifts were fully revegetated and stabilised through natural regeneration of

13572-620: Was recovered during a July 1992 project, and the anchor was installed in the yard of the Dossin Great Lakes Museum on Belle Isle . Since the 1980s, divers have recovered a total of six 1700s-era cannons from the river. The last was found in 2011 near the Cobo Center . They are believed to have been part of the pre- War of 1812 inventory kept by the British garrison in this area. Historians believe another three cannon may still be in

13689-410: Was the 1936 Curtis Prairie at the University of Wisconsin–Madison Arboretum . Civilian Conservation Corps workers replanted nearby prairie species onto a former horse pasture, overseen by university faculty including Aldo Leopold , Theodore Sperry , Henry C. Greene , and John T. Curtis . The UW Arboretum was the center of tallgrass prairie research through the first half of the 20th century and
