Trees and Shrubs


Untitled Document ALDER, THINLEAF (Alnus incana, formerly tenuifolia) ALIN - Large shrub to small tree that can grow to a height of 30 feet and tends to form thickets. Branches are fairly straight and tend to point upward. Dark brown catkins resemble small pinecones. Thrives in moist to wet places from mid to high elevations and is commonly found along streambanks. Can grow in nitrogen-deficient soils since roots have nitrogen-fixing nodules. Provides food for upland gamebirds, songbirds, beaver, and hare; browse for deer and elk; and cover for wildlife and fish.

ALDER, SITKA (Alnus sinuata) ALSI - Multiple-stemmed shrub that grows to 15 feet, often forming dense thickets. Limbs are crooked and upward curving. Prefers moist soils along streambanks or on mountain slopes. Other characteristics similar to thinleaf alder above.

ALDER, RED (Alnus rubra) ALRU - Small to medium size tree that can grow to a height of 80 feet. Dark brown catkins resemble small pinecones. Found in wet areas in some Inland Northwest locales.

ASPEN, QUAKING (Populus tremuloides) POTRe - Tree that grows 30 to 80 feet in height and thrives in a variety of open sites with moist soils. Beautiful smooth, creamy to greenish white bark with scattered black splotches. Heart-shaped leaves tremble in the breeze and turn a splendid golden yellow in the fall. Widespread root system produces suckers from which new trees sprout, which can form dense groves. Prone to formation of cavities, which are used by a variety of cavity-nesters. Buds and catkins valuable to grouse and songbirds. Tender bark, twigs, and leaves a favorite food of rabbits, hoofed browsers, beaver, and porcupine.

BIRCH, WATER (Betula occidentalis) BEOC - Shrub or small tree that grows 15 to 30+ feet in height. Shiny, reddish brown bark with white horizontal streaks. Prefers moist, but well-drained soils. Frequently found in dense thickets along streams or on moist, open forest sites. Ideal for streambank stabilization but also makes a beautiful ornamental plant. Similar wildlife benefits as paper birch.

CEANOTHUS, REDSTEM (Ceanothus sanguineus) CESA - Shrub that grows 3 to 10 feet tall. Small, white flowers grow in clusters near tips of twigs. Prefers semi-shade and well-drained or dry soils. Often the early, dominant colonizer in cleared or burned areas. Roots have nitrogen-fixing nodules. Provides cover for wildlife and is browsed by many big game animals.

CHOKECHERRY, (Prunus virginiana) PRVI - Fast growing, hardy shrub or small tree that grows 10 to 20 feet in height. Dark green leaves and long, cylindrical clusters of white flowers that droop from the ends of twigs. Plant spreads by rhizomes and often forms dense thickets. Good for windbreaks and erosion control. Edible, dark red to purplish berries attract bird of all kinds as well as small and large mammals. Hoofed browsers and rabbits also feast on twigs, leaves, and bark.

COTTONWOOD, BLACK (Populus trichocarpa) POTRi - Fast growing tree that grows up to 120 feet in height. Tolerant of flooding and commonly found near the water's edge of streambanks or lakeshores. Established stands provide food and cover for many wildlife species and enhance fish habitat by stabilizing streambanks and by providing shade and large woody debris. Important nesting tree for great blue heron, bald eagle, and osprey. Mature trees often provide homes for cavity nesters.

Control weed and grass competition in order to prevent seedling mortality and improve growth rates.

DOGWOOD, RED-OSIER (Cornus stolonifera) COST - Many-stemmed shrub that grows in dense clumps and ranges from 6 to15 feet tall. Distinctive bright red stems. Prefers moist soils along streambanks. High aesthetic and erosion control value. Leaves and twigs provide browse for deer and elk; fruit eaten by birds and black bear. Thickets provide good nesting and cover habitat for various types of wildlife.

HAWTHORN, DOUGLAS (Crataegus douglasii) CRDO - Large shrub or small tree that grows 5 to 25 feet in height. Has brightly-colored fall foliage, aesthetically pleasing. Thorns from 0.5 to 2 inches in length protrude from limbs. Dense, nearly impenetrable thickets create excellent wildlife cover and favorite nesting sites for many birds. Small, black apple-like fruit remains on the plant throughout the winter providing an important food source for many birds and mammals. Good erosion control plant for streambanks and moist slopes.

MAPLE, ROCKY MOUNTAIN (Acer glabrum) ACGL - Shrub or small tree that grows 3 to 30 feet in height. Typical maple-shaped leaves are relatively small, 1 to 3 inches in width. Dark green leaves turn a vivid red and crimson in the fall. Stems are mostly grayish-brown but new twigs are bright red. Prefers moist sites. Seeds, buds, and flowers are eaten by a number of birds and mammals. Twigs and leaves are food for hoofed browsers and birds use leaves and seed stalks for nesting material.

NINEBARK (Physocarpus malvaceus) PHMA - Small shrub that grows 2 to 5 feet tall. Peeling bark on stems is an identifying characteristic. Small, white flowers form clusters at the ends of twigs. Bright red autumn leaves give the plant an ornamental value. Provides cover and browse for game. Found at the upland edges of the riparian zone and on drier sites.

OCEAN-SPRAY (Holodiscus discolor) HODI - Shrub that grows up to 10 feet in height. Masses of loose, creamy white flowers form drooping plumes that bloom for several months. Thrives on drier sites.

POPLAR, IDAHO HYBRID (Populus spp.) POID - Very rapid growing tree to 80 feet in height. Prefers full sun. Grows best on well-drained soils but needs large quantities of water. Provides nesting habitat for a number of bird species and is browsed by many hoofed mammals. Good choice for windbreaks.

SERVICEBERRY (Amelanchier alnifolia) AMAL - Hardy shrub or small tree that grows to 20 feet. Clusters of fragrant white flowers in the early spring produce edible purple berries. Fruit attracts birds and big game browses the foliage. Favorite treat of bears. Grows well on most soils but intolerant of saline or alkaline sites. Prefers sun or partial shade and is commonly found on rocky slopes or drier edges of riparian zones.

SNOWBERRY, COMMON (Symphoricarpos albus) SYAL - Small shrub that grows to 2 to 6 feet. Adapted to a wide range of habitats but is saline and alkaline intolerant. Spreads by rhizomes. White, waxy berries remain on the branches throughout the winter and attract birds and small mammals. Leaves and twigs browsed by deer. Useful as nesting and cover habitat.

SPIREA, DOUGLAS (Spirea douglasii) SPDO - Small shrub that grows 4 to 7 feet tall. Favors wet soils of swamps, damp meadows, marsh borders and streambanks. Prefers open sites, spreads by rhizomes, and commonly forms dense clumps. Elongated, upright clusters of bright pink flowers are eye-catching in mid-summer. Excellent for streambank stabilization.

Seedlings of deciduous trees and shrubs may need protection from animals the first few years after planting.
