Swamp ash
Swamp ash is a common name for several North American trees in the genus Fraxinus which may grow in swamps and other wetlands. The wood of swamp ashes is relatively low in density and is used in the construction of musical instruments, particularly electric guitars.
Swamp ash may refer to:Fraxinus caroliniana, native to the southeastern United States and CubaFraxinus nigra, native to the northeastern United States and eastern CanadaFraxinus pennsylvanica, broadly distributed in North America east of the Rocky Mountains
, climate change is creating a shortage of swamp ash suitable for making electric guitars.
