RULE 2 PERMITS <br />selecting reclaimed mine lands, reseeded Conservation Reserve Program (CRP) croplands etc. as an <br />important, if not essential, component of the winter range needed for the expanding elk population in <br />northwest Colorado. <br />It is important that the reader be aware that many traditional concepts regarding elk are becoming <br />outdated as elk populations change their habits in response to increased hunting pressures, increased elk <br />populations and improvements on winter ranges. <br />Because deer, unlike elk, do not concentrate in certain areas to bear their young, no key deer fawning <br />areas are known to exist; however, the large number of does with fawns commonly observed throughout <br />the early summer in or near dense stands of oak and service berry indicates there is high usage by the does <br />of these areas. In addition, most doe and fawn observations are made near water ponds located on the site, <br />along Taylor Creek and near the springs in upper Streeter Draw, because the does do not like to move <br />considerable distances to water when the fawns are very young. From this observation, it appears that <br />those areas of good cover within one-fourth to one-half mile of water are key areas for fawning. <br />Data collected from 1974 to 1977 indicated that browse use by deer, elk and cattle, both past and present, <br />was excessive. This was evidenced by the "hedged" and "decadent" condition of the majority of the <br />browse found in the study area. All browse species (e.g., oak, serviceberry, sage, rabbitbrush, snowberry, <br />and bitterbrush) showed signs of over-utilization. <br />The net result of the past browse use was a reduction in annual growth with less available palatable <br />forage. In addition, species such as oak and serviceberry have grown taller, with palatable growth limited <br />to those portions of the shrubs that are out of reach to all but the largest elk. In some instances, even the <br />larger elk are unable to reach the growth. <br />As the oak and serviceberry have grown taller, they have created large windbreaks. In the winter these <br />dense areas of cover hold the snow, which becomes deep enough to limit all access by deer and elk. The <br />serviceberry-snowberry transects showed low use for both 1974-1975 and 1975-1976. The snowberry <br />bushes which were completely covered by deep snows showed no use. The use of the serviceberry has <br />been limited to bushes near the edges of the stands where less snow buildup occurs. <br />During the winter of 1975-1976, deer use of some areas changed from the winter of 1974-1975. The big <br />sage transect showed a higher use in 1975-1976. The snow cover was much lower in 1975-1976 and <br />1976-1977 than in 1974-1975, and a result the deer were better able to utilize the big sage. <br />Data from the extensive transects which were biased towards key areas of use, show that the areas to the <br />south and east of the mine are key forage areas for the deer in the winter. These are primarily large <br />expanses of south and east-facing sagebrush-covered slopes where there is less snow cover throughout the <br />winter. <br />Traditionally, the most extensive use on the site has been during the summer and fall months by cattle, <br />deer, and elk. Over-grazing at times by cattle in conjunction with high numbers of deer and elk have <br />resulted in reduced carrying capacity and a general decline in the condition of the range over several <br />years. <br />The reduced carrying capacity resulting from the overuse of the range created an increase of pressure on <br />the more healthy plants. Certain more desirable species, such as bitterbrush, were overutilized throughout <br />the year and offered little or no forage during the critical winter months. In most instances, 8 to 10 inches <br />of snow totally covered the plants. <br />Rule 2 Permits 2.04.11-4 Revision Date: 6/23/08 <br />Revision No.: MR-91
