SPECIES: Rubus discolor | Himalayan Blackberry
WOOD PRODUCTS VALUE : NO-ENTRY IMPORTANCE TO LIVESTOCK AND WILDLIFE : Wildlife: The Himalayan blackberry provides food and cover for many wildlife species. Fruits of blackberries are eaten by numerous birds, including the northern bobwhite, scaled quail, ruffed grouse, sharp-tailed grouse, California quail, ring-necked pheasant, blue grouse, gray (Hungarian) partridge, band-tailed pigeon, gray catbird, northern cardinal, American robin, yellow-breasted chat, pine grosbeak, summer tanager, orchard oriole, brown thrasher, thrushes, and towhees [1,30,33]. Mammals such, as the coyote, common opossum, red squirrel, raccoon, gray fox, red fox, skunks, squirrels, chipmunks, and black bear, also feed on blackberries [30,33]. Deer, rabbits, and mountain beaver consume the buds, stems, and leaves of blackberries [30,33]. The Himalayan blackberry is considered a primary elk browse in parts of California, where it is used primarily during the winter months [12]. Porcupines and beaver feed on the cambium, buds, and stems of many species of blackberries [30]. Livestock: Blackberries, in general, provide only poor browse for domestic livestock [30]. However, the specific value of Himalayan blackberry has not been documented. In some areas, this shrub may represent a barrier to the movement of livestock. Domestic sheep occasionally become entangled in the spiny foliage of this sprawling shrub [13]. PALATABILITY : Fruits of blackberries are highly palatable to many birds and mammals. Palatability of Himalayan blackberry browse has not been determined. NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : Dense blackberry thickets form suitable nesting sites for many species of birds [33]. Mammals, such as rabbits, red squirrel, black bear, and beaver, use blackberry thickets as hiding or resting sites [30]. VALUE FOR REHABILITATION OF DISTURBED SITES : Most blackberries are valuable for preventing soil erosion on barren, infertile, disturbed sites [3,30]. The Himalayan blackberry has been successfully planted in riparian areas along Columbia River impoundments in north-central Washington [5]. Good survival was observed up to 5 years after the initial plantings were made [5]. Blackberries may be propagated vegetatively, transplanted, or seeded onto disturbed sites. According to Brinkman [3], seed which has been scarified can be successfully planted in the late summer or early fall. Seed planted in the fall does not require cold treatment. Previously stratified and scarified seed can be planted in the spring. Good results have been obtained after seeds were planted with a drill and covered with 1/8 to 3/16 inch (0.3-0.5 cm) of soil [3]. OTHER USES AND VALUES : Himalayan blackberry is the most commonly harvested wild blackberry in western Washington and Oregon, although its fruit is reportedly less flavorful than that of the native trailing blackberry (Rubus ursinus) [7]. It is a preferred berry for fruit pies [7]. The fruit, roots, and stems of blackberries have been used to make various medicinal preparations [3]. Many blackberries are grown in gardens or as ornamentals. Himalayan blackberry was first cultivated in 1890 [3]. MANAGEMENT CONSIDERATIONS : Competition: The introduced Himalayan blackberry has spread aggressively in many parts of the United States. It is now regarded as a serious pest in parts of the Pacific Northwest, particularly west of the Cascades [14]. Chemical control: Good to excellent control of the Himalayan blackberry can be obtained through the use of glyphosate, picloram + 2,4-D, triclopyr ester, or triclopyr amine [4].
