Permit M77-424 Amendment 1 <br />EXHIBIT J <br />VEGETATION INFORMATION <br />Exhibit J <br />Page 1 of 3 <br />Vegetation information is provided in Exhibit J of the original mine permit and has been <br />supplemented in this exhibit. The original permit identified 10 vegetation community <br />types in the vicinity of Logan Wash Mine and Logan Wash that are related to geographic <br />sub-settings characterized by altitude, soils, slope aspect, and geology. Soil types <br />referenced in this exhibit are consistent with the soil information given in Exhibit I and <br />shown in Exhibit C, Sheet 6, Volume 2 of this permit amendment, utilizing the most <br />recent soil survey given by the Natural Resources Conservation Service Web Soil Survey <br />(2005). A map of vegetation for this permit amendment is provided in Exhibit C, Sheet <br />3, Volume 2. <br />Based on field observations, 3 of the vegetation community types identified in the <br />original permit and 3 additional vegetation communities exist along the water <br />transmission pipeline alignment and at the evaporation pond site. The 3 community types <br />described in the original permit include alluvial bottom lands, shadscale-greasewood <br />shrublands, and Douglas-fir forests. For the purposes of this amendment and Exhibit C <br />Sheet 3, the alluvial bottom lands community includes the shadscale-greasewood <br />shrubland community. It should be noted however, that the shadscale-greasewood <br />shrubland community is most common on the valley floor at elevations less than 5,800 <br />feet above mean seal level. Detailed descriptions of these communities aze provided in <br />Exhibit J of the original permit. <br />Concerning the three additional vegetation communities, the original permit describes the <br />characteristic vegetation of two of these areas as a pinyon juniper woodlands community <br />and a brush community. However, based on field observations, we have found that these <br />communities appear to be mixed, and are either dominated by pinyon juniper or <br />mountain brush. We have created two separate vegetation communities that for the <br />purposes of this amendment we will call pinyon-juniper brash mix, and brush and <br />pinyon juniper mix. These observations are generally consistent with Bureau of Land <br />Management GJFO Fire Management Plan vegetation maps of the area available at <br />http://www.co.blm.gov/gjra/planning.htm (2005). The dominant brush species include <br />gamble oak (Quercus gambelii), true mountain mahogany (Cerocarpus montanus), <br />service berry (Amelanchier alnifolia), snowberry (Symphoricarpos) and rubber <br />rabbitbrush (Crysothamnus nauseous). The pinyon (Pinus edulis} and Utah juniper <br />(Juniperus osteosperma) are the tentatively identified tree species in the azea. <br />The final vegetation community is found in the area immediately south of the evaporation <br />pond and has been characterized by field observations as brush-dominated grassland. <br />The brush-dominated grassland is chazacterized by sparse vegetation on weathered shale, <br />mudstone, and siltstone; no characteristic A-horizon soil is evident in this azea.
