Profile Video: See this plant in the following landscape: Cultivars / Varieties: VIDEO Created by Elizabeth Meyer for " Trees, Shrubs and Conifers" a plant identification course offered in partnership with Longwood Gardens. Brittle branches are susceptible to damage from high winds, snow and ice. Potential disease problems include fungal leaf spots, powdery mildew, rust, anthracnose, cankers and ash yellows. Other potential problems are ash borer, lilac borer, carpenter worm, oyster shell scale, leaf miners, fall webworms, ash sawflies and ash leaf curl aphid. Emerald ash borer will will typically kill an ash tree within 3 to 5 years after infestation and, once infestation occurs, it is difficult to eradicate. Insects, Diseases, and Other Pest Problems: Planting new ash trees is no longer recommended due to the trees' susceptibility to the emerald ash borer, a pest that feeds under the bark and bores into the wood. White ash tends to be easily transplanted and established. The cultivars of white ash are generally much more desirable than seedling trees and are well worth seeking out. It is worth considering planting female ash trees though, because the fruits are born in clusters among the foliage and add a sophisticated note of unusual dimension to the trees in late summer. Purchasing male trees will prevent you from having to deal with the fruits which can be a bit of a nuisance near a walkway. The tree produces a one-winged, dry, flattened samara with a full, rounded, seed cavity that matures in the fall.Īsh trees have male and female flowers on separate trees and only the female flowers develop into fruits. Small, light green to purple flowers, with no petals, mature in loose panicles in the spring. ![]() The bark is yellow-brown to light gray and corky with deep furrows that separate short, pointed ridges. The leaves are opposite and pinnately compound with 5 to 9 (mostly 7) leaflets. In open areas, the white ash crown is ovoid, in forested areas the crown is more narrow and pyramidal. It can also extend into the beech-birch-maple forests at 4000 to 5000 foot elevations. In the west, it is more likely to be found among yellow poplar, black cherry, basswood, and oak. In the eastern part of the state, it can typically be found with swamp chestnut, willow, cherrybark oak, loblolly pine, and sweet gum. The white ash grows best in the rich moist soils of mountain coves or river bottom lands. It usually grows to 60 to 90 feet tall with a 2 to 3 foot trunk diameter, but it can reach 120 feet tall and is the largest of the native ashes. White ash is a deciduous tree, native to North Carolina and found throughout the state except for the lower coastal region (it does not tolerate exposure to salt air). The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future.Phonetic Spelling FRAK-si-nus a-mer-ih-KAY-nah Description The species is facing a high risk of extinction in the wild. The species is facing an extremely high risk of extinction in the wild. The species is in imminent risk of extinction in the wild. Known only to survive in captivity or as a naturalized populations well outside its previous range. No reasonable doubt that the last individual has died. The following tags are used to highlight specific species' conservation status as assessed by the IUCN: The taxonomy and naming of the individual species is based on those currently used by the Reptile Database as of 20 September 2011 and supplemented by the common names and taxonomy from the IUCN where no Reptile Database article was available. This list is derived from the Reptile Database which lists species of reptile and includes those reptiles that have recently been classified as extinct (since 1500 AD). There are 154 reptile species in Ghana, of which one is critically endangered, one is endangered, two are vulnerable and two are near threatened. This is a list of the reptile species recorded in Ghana.
