The tree line is the edge of a habitat at which trees are capable of growing and beyond which they are not. It is found at high elevations and high latitudes . Beyond the tree line, trees cannot tolerate the environmental conditions (usually low temperatures, extreme snowpack, or associated lack of available moisture). The tree line is sometimes distinguished from a lower timberline , which is the line below which trees form a forest with a closed canopy .

Southern Rata forests exist on Enderby Island and Auckland Islands (both 50°S) and these grow up to an elevation of 370 metres (1,200 ft) in sheltered valleys. These trees seldom grow above 3 m (9.8 ft) in height and they get smaller as one gains altitude, so that by 180 m (600 ft) they are waist-high. These islands have only between 600 and 800 hours of sun annually. Campbell Island (52°S) further south

Some time later the manager of the Chrysolite mine fooled an outside mining engineer into overestimating the mine's ore reserves. The city's fortunes declined with the repeal of the Sherman Silver Purchase Act in 1893, although afterwards there was another small gold boom. Mining companies came to rely increasingly on income from

World War II caused an increase in
913-487: A major impact on the ability of trees to place roots into the ground. When roots are too shallow, trees are susceptible to windthrow and erosion. Trees can often grow in river valleys at latitudes where they could not grow on a more exposed site. Maritime influences such as ocean currents also play a major role in determining how far from the equator trees can grow as well as the warm summers experienced in extreme continental climates. In northern inland Scandinavia there

In early 1878, Meyer, along with Leadville's pioneer smelter entrepreneur, Edwin Harrison, after whom the famed Harrison Avenue is named, and Tabor established a post office in Leadville, with George L. Henderson designated as postmaster on July 16, 1877. The post office and the telegraph office both prospered, with Tabor serving as postmaster from February 19 to December 13, 1878. It
1328-537: A supply of moisture through the early part of the growing season. However, snow accumulation in sheltered gullies in the Selkirk Mountains of southeastern British Columbia causes the tree line to be 400 metres (1,300 ft) lower than on exposed intervening shoulders. In some mountainous areas, higher elevations above the condensation line, or on equator-facing and leeward slopes, can result in low rainfall and increased exposure to solar radiation. This dries out

The Leadville Historic District , designated a National Historic Landmark in 1961, contains many historic structures and sites of Leadville's mining era. In the late 19th century, Leadville was the second most populous city in Colorado, after Denver . The Leadville area was first settled in 1859 when placer gold
1743-515: Is often much lower than in corresponding altitudes inland and in larger, more complex mountain systems, because strong winds reduce tree growth. In addition, the lack of suitable soil, such as along talus slopes or exposed rock formations, prevents trees from gaining an adequate foothold and exposes them to drought and sun. The arctic tree line is the northernmost latitude in the Northern Hemisphere where trees can grow; farther north, it

Here are some typical polar treelines: Trees exist on Tierra del Fuego (55°S) at the southern end of South America, but generally not on subantarctic islands and not in Antarctica. Therefore, there is no explicit Antarctic tree line. Kerguelen Island (49°S), South Georgia (54°S), and other subantarctic islands are all so heavily wind-exposed and with
1992-544: Is taken over all days whose mean temperature is above 0.9 °C (33.6 °F). A growing season of 94 days above that temperature is required for tree growth. Because of climate change , which leads to earlier snow melt and favorable conditions for tree establishment, the tree line in North Cascades National Park has risen more than 400 feet (120 m) in 50 years. Several types of tree lines are defined in ecology and geography : An alpine tree line
2075-433: Is the highest elevation that sustains trees; higher up it is too cold, or the snow cover lasts for too much of the year, to sustain trees. The climate above the tree line of mountains is called an alpine climate , and the habitat can be described as the alpine zone . Treelines on north-facing slopes in the northern hemisphere are lower than on south-facing slopes, because the increased shade on north-facing slopes means

According to the U.S. Census Bureau , the city of Leadville has an area of 1.1 square miles (2.9 km ), all land. The lower part of California Gulch runs past the southern edge of the city, flowing west 3 miles (5 km) to the Arkansas River . Leadville has an alpine subarctic climate ( Dfc ) with cold winters and mild summers, bordering on
2241-547: Is too cold all year round to sustain trees. Extremely low temperatures, especially when prolonged, can freeze the internal sap of trees, killing them. In addition, permafrost in the soil can prevent trees from getting their roots deep enough for the necessary structural support. Unlike alpine tree lines, the northern tree line occurs at low elevations. The arctic forest–tundra transition zone in northwestern Canada varies in width, perhaps averaging 145 kilometres (90 mi) and widening markedly from west to east, in contrast with

The first miners lived in a rough tented camp near the silver deposits in California Gulch. Initially, the settlement was called "Slabtown", but when the residents petitioned for a post office, the name "Leadville" was chosen. By 1880, Tabor and Meyer's new town had gas lighting, water mains, 28 miles (45 km) of streets, five churches, three hospitals, six banks, and
