Widely planted for habitat restoration, Chokecherry and Blue Elderberry are important species in the high desert ecosystem. These small trees succeed in riparian areas — lands that occur along the edges of rivers, streams, lakes, and other water bodies — making them an essential part of Oregon Natural Desert Association’s work to steward desert waterways. The trees are featured in ONDA work to restore the Malheur River in partnership with the Burns Paiute Tribe.

Chokecherry (Prunus virginiana)

Found throughout North America from the high arctic Canadian provinces and coast to coast in the United States, these small trees show up in archeological middens, attesting to their cultural importance among Native Americans for millennia. In 1629 they were exported to England and were cultivated as an orchard crop in the American colonies as early as 1724.

Prunus is the Roman-named family of cherries, prunes, and plums, while virginiana was assigned by Linneaus, reflecting their presence in colonial Virginia. The common name warns of the astringent quality of the raw fruit.

The early spring flowers attract butterflies, honeybees and ants to their nectar, which in turn attracts insect-eating birds, providing food, cover and nesting habitat. Bears, as well as hares, rodents, and birds eat the fruit, and deer use the shrubs as a winter browse.

Widely planted for habitat restoration,  Chokecherry succeed in riparian areas and are an important part of ONDA’s efforts along the Malheur River, where they are spreading by suckering and may eventually form thickets. Like other riparian species, they provide streamside shade and their rhizomatous, net-like root structure helps prevent erosion.

Classified as shrubs or small trees, they may reach 30’ in height, with a spreading crown and alternate oval to elliptical leaves. The white, almond scented flowers are arranged in cylindrical racemes appearing as early as April. Fruits form a few months later, first appearing green, then darkening to red, purple, and black as the season progresses and the leaves turn salmon in fall.

Bobcat

Bobcat

Found only in North America, where it is the most common wildcat, the bobcat takes its common name from its stubby, or “bobbed,” tail. The cats range in length from two to four feet and weigh 14 to 29 pounds. Bobcats mainly hunt rabbits and hares, but they will also eat rodents, birds, bats, and even adult deer.

Latin name: Lynx rufus fasciatus

What defines Oregon’s high desert?

What defines Oregon’s high desert?

Bounded by the Cascade Mountains to the west and the Blue Mountains to the north, Oregon’s high desert covers approximately 24,000 square miles. Annual rainfall in the high desert varies from 5 to 14 inches. The average elevation is 4,000 feet; at 9,733 feet, the summit of Steens Mountain is the highest point in Oregon’s high desert. The terrain of the high desert was mostly formed by a series of lava flows that occurred between 30 and 10 million years ago.

Blue Elderberry (Sambucus nigra var. caerulea)

One of the most widely distributed shrubs in North America and Europe, the blue elderberry shows up as a possible fossil in John Day’s Clarno Nut Beds, incompletely identified but intriguing: fossil evidence points to a circum-global forest in the mid-latitudes of the Northern Hemisphere sometime during the Eocene, 56-32.9 million years ago; in other words, this shrub really gets around.

Names too suggest origin stories: Sambuca was an ancient Greek wind instrument, referencing the use of twigs to make whistles, and elder comes not from “old” but from the Anglo-Saxon “aeld”, meaning fire, because hollow stems of the shrub were used as bellows.

The flowers, bark, leaves, twigs and roots are a native pharmacopeia, and the berries are an important late-season food gift. Well-loved by bears, game birds, squirrels, deer, and elk, the shrubs provide food and nesting territory for a plethora of songbirds.

Widely used in riparian restoration projects, they are thriving in ONDA’s collaborative plantings with the Northern Paiute at Juntura along the Malheur River. Part of the desert stream’s thin green line, they provide streamside shade, sheltering other plant species, and helping to stabilize banks with their roots.

This 3-20’ shrub has yellow-white flowers in flat sprays that rise above compound pointy shaped leaves, followed by blackish-blue berries. If you have the opportunity, raise a glass to this remarkable shrub, known and treasured by cultures across millennia spanning the globe, and right here in our desert backyard.
