Kent A. Gorham <br />Page Two <br />February 1, 1993 <br />ELK <br />The general statement regarding CYCC's elk study (see 1980 through <br />1987 reports) showing a lack of use of reclamation and selection of <br />aspen by elk indicates a somewhat incomplete review of the study <br />results. As pointed out by the Division, aspen (54% of all summer <br />relocations) is selected by elk, but only during summer (May-Oct.}. <br />Table 20, 1985 Report; Table 14, 1986 Report; Table 10, 1987 <br />Report; also show that elk select against aspen (3% of all <br />relocations) during the winter (Dec.-April). With regard to <br />reclamation, the above tables do show that the amount of <br />reclamation use is small during summer and is confined <br />predominately to edges during this period. However, they also show <br />that reclamation is selected for during the spring (Mar.-April) and <br />fall (Oct.-Dec.). Similar open habitats, i.e, cultivated and crop <br />reserve program (CRP) lands with abundant grass or grass like <br />forage are also selected for during the fall. When reclamation and <br />cultivated lands are combined they represent 54% of all relocations <br />during November and December and 26% during October and January. <br />Review of the elk location data will show that elk are often one or <br />two miles from vegetative cover (i.e, mountain shrub) during this <br />period. <br />It should be kept in mind during review of maps contained in the <br />elk study that it is the relative proportion of locations within a <br />particular habitat and t'me period that is indicative of use of <br />that habitat type. A casual glance would lead one to erroneously <br />believe aspen was the overriding habitat of choice only because the <br />main portion of study effort was spent during summer when aspen is <br />selected for. This results in a disproportionate number of <br />relocations associated with this time period. <br />Although total number of elk observed during aerial surveys were <br />not reported in the elk study reports, from 100 to 600 elk were <br />often counted in center areas of the reclamation following the <br />major hunting seasons. Recent personal observations and <br />discussions with local (Craig} CDOW personnel indicate there is <br />more elk use on the reclamation of the Craig area mines than there <br />were on premine habitats and that CRP grasslands are being heavily <br />used by elk. Thousands of elk often spend a major portion of the <br />fall and winter on these open habitats far from vegetative cover. <br />CDOW personnel attributed this in part to the quality of the <br />forage. Lyon (1980), literature provided by the Division via CDOW, <br />states "there are also numerous observations of elk using very <br />large open parks and hillsides..." and "The area of an opening <br />provides only one measure of a basic requirement for adequate <br />security in elk habitat. Size of opening, in fact, may be less <br />important than some other considerations - particularly for elk <br />herds that normally spend at least part of the year on ranges with <br />large natural openings." The only reason elk do not spend more of <br />the winter on reclamation in the CYCC study area is because the <br />
