Oregon ash

A deciduous, medium sized (30′-80′) tree, symmetrical in shape, growing about half as wide as it is tall. This tree may reach the age of 250 years and is fast growing the first third of those years, then grows slowly. Space 30′ apart.

Oregon ash is commonly found in riparian habitats. In open moist sites this tree can have short trunks and wide, round-topped crowns with large limbs. On dry sites or at high elevations Oregon ash is often a small, crooked tree. The seeds are eaten by birds and squirrels. Its preferred habitat is poorly drained, moist bottom land with deep soil rich in humus. Larval host for the Two-Tailed Swallowtail and Western Tiger Swallowtail butterflies.
