<br />component, if measures are not taken to minimize the grazing pressure. Although not <br />evaluated in the Cedar Creek monitoring or report, cattle use may possibly have been a <br />factor in the apparent seeding failure at the RSRDA borrow area, seeded in November 2002. <br />At the North Decline, the significant cheatgrass component has negatively impacted <br />establishment of seeded perennial grasses, forbs, and subshrub species. <br />The consultant's report included several recommendations for the operator to consider, <br />which would need to be addressed within a revision to the permit application. In general, <br />we concur with the concerns identified in the report, but we feel that alternative remedial <br />approaches may warrant consideration, prior to submittal of a revision to the reclamation <br />plan. Our comments in regard to recommended modifications and remedial treatments are <br />set forth below. <br />The report notes that the approved diversity standard includes the criterion that No <br />reclaimed area shall have a single species that represents greater than 70% relative <br />cover. The narrative further notes that "...the ubiquitous and invasive annual grass, <br />cheatgrass (Anisantha tectorum), has relative cover values approaching or <br />surpassing 70% in years favorable to growth in both the North Decline Area and <br />Greasewood Reference Area". This is the case, and in fact it is likely true of a high <br />percentage of the rangeland in the permit area and vicinity, particularly along the <br />valley bottoms with an open greasewood overstory. Cedar.Creek recommends that <br />the standard be modified to read No rec/aimed area sha// have acing/e anted <br />species that represents greater than 70% relative cover. <br />Cedar Creek's reasoning is that the original intent was to preclude a planted <br />monoculture where one species is overwhelmingly dominant. We would agree that <br />planted species were the primary consideration, but we feel that it would be <br />inappropriate to alter the standard in such a way that would allow for an invasive <br />annual grass to become more pervasive on reclaimed areas than on• similar <br />undisturbed adjacent areas. Although cheatgrass does havevalue for grazers and <br />certain birds during specific seasons, and is the dietary staple fot chukar partridge, a . <br />locally important game bird, a diverse community including a variety of lite forms <br />provides better year around habitat for a wider variety of species. We would <br />recommend the following modification: <br />No reclaimed area shall have a single species that represents greater than 70% <br />relative cover, with the exception of annual grasses. Annual grass species, singly or <br />in the aggregate, shall not exceed 70% relative cover, unless the aggregate relative <br />cover of annual grasses in the corresponding reference area exceeds 70%: In such <br />instances, re/ative cover of annua/ grasses in the reclaimed area shall not exceed the <br />relative cover of annual grasses in the reference area. <br />2. Sampling data indicated a high cheatgrass component and very low perennial <br />herbaceous component at the North Decline. Cool season grasses are a minor <br />component and warm season grasses, perennial forbs, and subshrubs are essentially <br />absent from the stand. The late sampling date could possibly have under- <br />represented ephemeral fobs, and to a lesser extent, cool season grasses, but based <br />on Division observations in recent years at various times of the year, we believe the <br />data provide a fairly accurate representation of the composition of perennial species <br />and annual grasses. We concur that remedial measures are warranted, to reduce <br />the cheatgrass competition and increase the perennial herbaceous component, <br />particularly warm season grasses and perennial forbs/subshrubs. <br />
