VALUE AND USE

SPECIES: Artemisia cana ssp. bolanderi | Bolander Silver Sagebrush
WOOD PRODUCTS VALUE : NO-ENTRY IMPORTANCE TO LIVESTOCK AND WILDLIFE : Bolander silver sagebrush basins are unique habitats that add to diversity and increase edge in areas dominated by low and tall sagebrush species. These sites are important foraging areas for mule deer, pronghorn, and sage grouse [4]. In Oregon, Bolander silver sagebrush is a highly preferred mule deer winter browse [24]. Mule deer use Bolander silver sagebrush communities more often than expected given their availability on central Oregon winter ranges [414]. Although browse use declines throughout the spring and summer, deer heavily utilize associated forage plants that are created by spring flooding, particularly Newberry cinquefoil (Potentilla newberryi) and desert combleaf (Polyctenium fremontii) [14]. Throughout the summer these "flats" are frequently used by pronghorn as resting and bedding areas. Generally, livestock utilization of Bolander silver sagebrush basins is slight; in most cases the herbaceous understory is not maintained through the grazing season. PALATABILITY : Bolander silver sagebrush is a highly palatable forage species on mule deer winter ranges in Oregon [14]. In feeding trials with captive animals this subspecies was among the more highly preferred of the seven sagebrush taxa compared [24]. It was highly preferred by mule deer in both the fall and winter and was utilized but not preferred by domestic sheep. NUTRITIONAL VALUE : The silver sagebrush complex is rated as fair in energy value and fair to good in protein value [5]. COVER VALUE : Cover is typically sparse in alkaline basins dominated by Bolander silver sagebrush. Not only do stands occupy sites of low productive potential [11], but many have been seriously overgrazed. Plants are seldom tall enough or dense enough to provide cover for animals larger than geese, swans, coyotes, or rabbits [4]. VALUE FOR REHABILITATION OF DISTURBED SITES : Bolander silver sagebrush appears to be a good revegetation candidate on sites to which it is adpated. Not only do plants sprout and layer, but they are also able to tolerate wide fluctuations in soil moisture conditions. However, no information was located regarding its use in rehabilitation projects. Plains silver sagebrush (A. cana ssp. cana) has been successfully established on coal spoils in eastern Montana [9]. McArthur [16] indicated that Bolander silver sagebrush is generally adapted for planting on sites having poorly drained, heavy soils. Monsen [19] recommended that silver sagebrush be used for riparian plantings in mountain brush and sagebrush/desert communities. Plants can be propagated via stem or root cuttings and also by wildlings [6,9]. Transplant material should consist of rooted cuttings, 1-0 nursery stock, or hardened-off, containerized stock. OTHER USES AND VALUES : Waterholes are often developed in basins dominated by Bolander silver sagebrush. Drainage ditches are dug across the basin floor to rapidly concentrate spring-runoff from wide, shallow naturally occurring ponds into deeper reserviors where the water does not evaporate as readily. Consequently, a reliable water source is maintained further into the livestock grazing season [14]. In smaller basins the drainage is so greatly improved that big sagebrush (Artemisia tridentata) and rabbitbrush (Chrysothamnus ssp.) are able to invade and sometimes replace stands of silver sagebrush [4,14]. Another method of creating additional water sources without sacrificing the unique qualities of silver sagebrush communities involves the installation of "guzzlers" (catchment aprons with storage tanks) in adjacent community types [14]. Silver sagebrush has been used as an ornamental in England. In America, this species has been used historically as fuelwood by both Indians and white settlers [17]. MANAGEMENT CONSIDERATIONS : Opportunities to increase forage production within Bolander silver sagebrush basins are low. Few introduced species are adapted to the heavy clay soils and seasonal flooding characteristic of these sites [3]. Stands are best left untilled and unsprayed.
