56-458: A biological control for the management of EAB populations in the United States. The public is being cautioned to avoid transporting unfinished wood products, such as firewood, to slow the spread of this insect pest. Damage occurs when emerald ash borer larvae feed on the inner bark, phloem , inside branches and tree trunks. Feeding on the phloem prevents nutrients and water transportation. If
84-500: A common axis. For example, once-divided leaf blades having leaflets arranged on both sides of a rachis are pinnately compound leaves. Many palms (notably the feather palms ) and most cycads and grevilleas have pinnately divided leaves. Most species of ferns have pinnate or more highly divided fronds , and in ferns, the leaflets or segments are typically referred to as "pinnae" (singular "pinna"). Plants with pinnate leaves are sometimes colloquially called "feather-leaved". Most of
112-671: A considerable litter problem with their seeds. Rowans or mountain ashes have leaves and buds superficially similar to those of true ashes, but belong to the unrelated genus Sorbus in the rose family . The tree's common English name, "ash", traces back to the Old English æsc , which relates to the Proto-Indo-European for the tree, while the generic name originated in Latin from a Proto-Indo-European word for birch. Both words are also used to mean " spear " in their respective languages, as
140-498: A few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara . Some Fraxinus species are dioecious , having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ashes can cause
168-517: A good food source for the frogs, but also reduces its resistance to the ash borer . Species with higher leaf tannin levels (including maples and non-native ash species) are taking the place of native ash, thanks to their greater resistance to the ash borer. They produce much less suitable food for the tadpoles, resulting in poor survival rates and small frog sizes. Ash species native to North America also provide important habitat and food for various other creatures native to North America. This includes
196-477: A reduction in the supply of healthy trees, especially in Europe, is making ash an increasingly expensive option. Ash was commonly used for the structural members of the bodies of cars made by carriage builders. Early cars had frames which were intended to flex as part of the suspension system to simplify construction. The Morgan Motor Company of Great Britain still manufactures sports cars with frames made from ash. It

It is lightweight, easy to work and sand, accepts glue, stain , paint and finish very well and is inexpensive. All this has made it a favourite of large factories mass-producing instruments. The Fender musical instrument company has been continuously and uninterruptedly using Ash to make electric guitars since 1956. Swamp ash
280-562: Is a wood-boring beetle accidentally introduced to North America from eastern Asia via solid wood packing material in the late 1980s to early 1990s. It has killed tens of millions of trees in 22 states in the United States and adjacent Ontario and Quebec in Canada. It threatens some seven billion ash trees in North America. Research is being conducted to determine whether three native Asian wasps that are natural predators of EAB could be used as
308-408: Is also used for making drum shells . Woodworkers generally consider ash a "poor cousin" to the other major open pore wood, oak, but it is useful in any furniture application. Ash veneers are extensively used in office furniture. Ash is not used much outdoors due to the heartwood having a low durability to ground contact, meaning it will typically perish within five years. The F. japonica species

#1733084495173336-467: Is commonly referred to in contrast to "palmation", in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate , and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words. Botanically , pinnation is an arrangement of discrete structures (such as leaflets , veins , lobes , branches , or appendages ) arising at multiple points along
364-574: Is different from Wikidata All set index articles Ash-tree Fraxinus ( / ˈ f r æ k s ɪ n ə s / ), commonly called ash , is a genus of plants in the olive and lilac family, Oleaceae , and comprises 45–65 species of usually medium-to-large trees , most of which are deciduous trees, although some subtropical species are evergreen trees. The genus is widespread throughout much of Europe, Asia, and North America. The leaves are opposite (rarely in whorls of three), and mostly pinnately compound , though simple in
392-444: Is favored as a material for making baseball bats by Japanese sporting-goods manufacturers. Its robust structure, good looks, and flexibility combine to make ash ideal for staircases. Ash stairs are extremely hard-wearing, which is particularly important for treads. Due to its elasticity, ash can also be steamed and bent to produce curved stair parts such as volutes (curled sections of handrail) and intricately shaped balusters. However,
420-444: Is used a lot in guitar building because of its figure. It is a choice of material for electric guitar bodies and, less commonly, for acoustic guitar bodies, known for its bright, cutting edge and sustaining quality. Some Fender Stratocasters and Telecasters are made of ash, (such as Bruce Springsteen 's Telecaster on the Born to Run album cover), as an alternative to alder. Ash
448-638: Is widely planted as a street tree in the United States. The inner bark of the blue ash ( F. quadrangulata ) has been used as a source for blue dye . In Sicily, Italy, sugars are obtained by evaporating the sap of the manna ash , extracted by making small cuts in the bark. The manna ash, native to southern Europe and southwest Asia, produces a blue-green sap, which has medicinal value as a mild laxative, demulcent, and weak expectorant. The young seedpods of Ash trees, also known as "keys", are edible for human consumption. In Britain, they are traditionally pickled with vinegar, sugar and spices. In Greek mythology ,
476-553: The Meliae are nymphs associated with the ash, perhaps specifically of the manna ash ( Fraxinus ornus ), as dryads were nymphs associated with the oak . They appear in Hesiod 's Theogony, which states that they were born when drops of Ouranos's blood fell on the earth (Gaia). In Norse mythology , a vast, evergreen ash tree Yggdrasil ("the steed ( gallows ) of Odin "), watered by three magical springs, serves as axis mundi , sustaining
504-625: The fungus Hymenoscyphus fraxineus , causing ash dieback in a large number of trees since the mid-1990s, particularly in eastern and northern Europe. The disease has infected about 90% of Denmark's ash trees. At the end of October 2012 in the UK, the Department for Environment, Food and Rural Affairs (Defra) reported that ash dieback had been discovered in mature woodland in Suffolk ; previous occurrences had been on young trees imported from Europe. In 2016,

588-487: The ash is attacked, the branches can die and eventually the whole tree can as well. Ways to detect emerald ash borer infestation include seeing bark peeling off, vertical cracks in the bark, seeing galleries within the tree that contain powdery substance, and D-shaped exit holes on the branches or trunk. Not all of these may be present, but any of these warning signs could be an indication of possible infestation. The European ash, Fraxinus excelsior , has been affected by

#1733084495173616-401: The ash tree was reported as in danger of extinction in Europe. Ash is a hardwood and is dense (within 20% of 670 kg/m for Fraxinus americana , and higher at 710 kg/m for Fraxinus excelsior ), tough and very strong but elastic , extensively used for making bows , tool handles, baseball bats , hurleys , and other uses demanding high strength and resilience . Ash
644-556: The following definitions are from Jackson's Glossary of Botanical Terms : The term pinnula (plural: pinnulae ) is the Latin diminutive of pinna (plural: pinnae ); either as such or in the Anglicised form: pinnule , it is differently defined by various authorities. Some apply it to the leaflets of a pinna, especially the leaflets of bipinnate or tripinnate leaves. Others also or alternatively apply it to second or third order divisions of

Many mammalian species from meadow voles eating the seeds to white-tailed deer eating the foliage to silver-haired bats nesting will also make use of ash trees. Ash is used as a food plant by the larvae of some Lepidoptera species ( butterflies and moths ). The emerald ash borer ( Agrilus planipennis ), also called EAB,
756-460: The wood is good for shafts. Species are arranged into sections supported by phylogenetic analysis: North American native ash tree species are a critical food source for North American frogs, as their fallen leaves are particularly suitable for tadpoles to feed upon in ponds (both temporary and permanent), large puddles, and other water bodies. Lack of tannins in the American ash makes their leaves
784-402: Was also widely used by early aviation pioneers for aircraft construction. It lights and burns easily, so is used for starting fires and barbecues , and is usable for maintaining a fire, though it produces only a moderate heat. The two most economically important species for wood production are white ash, in eastern North America, and European ash in Europe. The green ash ( F. pennsylvanica )
