Interactions between Mule Deer and Cattle on Big Sagebrush Range in British Columbia

Interaction between deer and cattle took various forms. The potential for direct competition was greatest in spring. Both deer and cattle selected bluebunch wheatgrass and crested wheatgrass while Sandbergs bluegrass was most often used by deer. Evidence of indirect interaction was observed. Moderate or heavy fall grazing by cattle made the spring forage more attractive to deer by removing mature forage. Light grazing did not exert any appreciable effect on deer distribution. The spring range of mule deer in south central British Columbia is relatively restricted, usually below 775 m elevation. This range is also used by cattle in both spring and fall, providing forage at a time crucial to a viable ranching operation. Common use of the range ensures that interaction between cattle and deer will occur. The type and extent of interaction was not known but was believed to be most critical in the food niche. A project was initiated in 1972 near Kamloops, British Columbia, to study interaction between the two species of ungulates for the range resource in terms of food, time and space. The study was supported by the Agriculture Canada Research Station, the British Columbia Fish and Wildlife Branch, and the British Columbia Ministry of Forests. Some of these have been reported previously (Tucker et al. 1976; Willms et al. 1976; McLean and Willms 1977; and Tucker et al. 1977). Site Description The study area was on the north side of Kamloops Lake, about 24 km west of Kamloops. This area lies within the big sagebrush (Artemisia tridentuta), ponderosa pine (Pinusponderosa), and Douglasfir (Pseudotsugu menziesii) zones. The land rises steeply from the lake, at 335 m, to a series of knolls and a relatively flat area before rising again within the open forest. Maximum elevation on this range is 760 m. Snowfall is light and the direct southern exposure promotes early growth and a warm environment. The range had been heavily grazed from 1947 until 1965, when the grazing permit was cancelled to allow rehabilitation of overgrazed areas. One hundred hectares on the flat area were seeded to crested wheatgrass (Agropyron deserforum) in 1968. Cattle normally use this range from early November to mid-December and again from early April to the end of May. The same area may be occupied by deer from early December to the end of May, although the greatest use occurs in a l-month period in March and April. Some deer may remain on this range into the summer. Methods Four habitats were recognized on the study area. The forested range I IIC author\ arc pradudte student. Plant Science.

Countering misinformation concerning big sagebrush

The USDA Forest Service, Rocky Mountain Research Station recently published the Research Paper, "Countering Misinformation Concerning Big Sagebrush," by Bruce L. Welch and Craig Criddle (RMRS-RP-40, July 2003). The authors state and discuss eight purported "axioms" regarding the ecology and management of big sagebrush. Publication of this report has generated a great deal of interest about the present state of science regarding big sagebrush and its relation to fire, grazing, and wildlife habitat. In addition, concerns have been expressed about some of the interpretation and analyses contained in the paper and the language in which they are expressed. The views expressed by the authors are their own and do not reflect the policy or views of the USDA Forest Service. We acknowledge and respect the concerns that have been expressed about the tone and language used in this paper, and apologize to anyone who might have been offended. This would normally not have passed peer and policy review prior to publication by the Rocky Mountain Research Station. We strive to be a source of quality and unbiased scientific information. In light of the large distribution this publication has already received, I believe it is important to take positive action to provide opportunity for rebuttal and to publish a subsequent document that more broadly clarifies the debate and uncertainty about the ecology of big sagebrush. The Rocky Mountain Research Station is in the final stages of publishing a thorough book-length synopsis of current information on big sagebrush by Dr. Bruce L. Welch. We have completed extensive scientific peer review and careful policy review of this book, and this new publication will be a more complete and authoritative reference on the ecology of big sagebrush. In response to the interest and debate expressed related to the initial paper and in recognition of the considerable uncertainty that remains in the scientific literature regarding the larger science issues about big sagebrush, we invite interested scientists to help us better present a diversity of views on this topic. During the next year, we will assemble and publish a subsequent paper that discusses these issues further and helps provide a broader understanding and synthesis of the areas of disagreement on ecology and management of big sagebrush. We will include alternative perspectives on the "axioms" contained in the paper by Welch and Criddle, and also seek to achieve a level of synthesis and consensus as to the present scientific understanding, what areas of uncertainty and disagreement remain, and what research is needed to help resolve these uncertainties.
