Alder trees by the Beaulieu River at Longwater Lawn, England Alder is the common name of a genus of flowering plants (Alnus) belonging to the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes.
Wikimedia Commons has media related to Fraxinus americana. Fraxinus americana, the white ash or American ash, is a species of ash tree native to eastern and central North America. It is found in mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas.
As a hardwood, alder is used in making furniture, cabinets, and other woodworking products. For example, in the television series Northern Exposure season 3 episode "Things Become Extinct" (1992), Native American Ira Wingfeather makes duck flutes out of alder tree branches while Ed Chigliak films.
Color/Appearance: Unlike most other hardwoods, the sapwood of maple lumber is most commonly used rather than its heartwood. Sapwood color ranges from almost white, to a light golden or reddish brown, while the heartwood is a darker reddish brown. Silver Maple can also be seen with curly or quilted grain patterns.
(Also note: Black Maple isn’t quite as hard as its close relative, Hard Maple, and ranks in the mid-range, with a hardness of 1,180 lb f.) Taking the hardness data within context of other hardwoods, Soft Maple may be used as a valid substitute for Hard Maple in most situations where a hardwood of moderate density is called for.
