:~ <br /> <br />The importance of the White River to endemic fish in the Upper <br />Colorado River Basin lies in its flow contribution to the Green <br />River. Although no squawfish Larvae have ever appeared in collec- <br />tions from the White River in Colorado, and spawning is not suspect- <br />ed, it is believed that major Green River tributaries, such as the <br />White River, exert a strong influence on downstream endemic fish <br />populations by maintaining flow patterns conducive to successful <br />reproduction and larvae development. <br />Cultural <br />Approximately one-half of the application area has been inventoried. A <br />total of S1 sites, 46 isolated finds, and 15 localities have been recorded <br />within and immediately adjacent to the mine permit and lease application <br />area as being of cultural and/or historic nature. No sites within the <br />lease application area have been identified as potentially eligible for <br />the National Register of Historic Sites. <br />Visual <br />The landform of this tract lacks diversity, is composed of flat to Bolling <br />hills and is sparsely vegetated. The entire area rates a VRM Class IY <br />with medium sensitivity and law scenic quality. <br />PaleontoloRv <br />The !linor Coal Unit (Iles) contains pelecypods, leaf impressions, fossil <br />plants, ammonites, and Inoceramus clams. <br />The main coal unit and upper unit (Williams Fork) has been characterized <br />as having an almost total lack of fossils, except Eor trace fossils. <br />Nevertheless, the following fossils have been found and recorded: fossil <br />plants, Leaf impressions, ammonites, pelecypods and gastropods. Fossils <br />common to the Wasatch Formation are as follows: vertebrate fossils, <br />ostracods, gastropods, and fossil leaves. <br />All of the Eosail remains Likely to be found at the proposed lease tract, <br />with the exception of vertebrate remains, have been characterized as com- <br />mon types that have a wide stratigraphic range and broad distribution, so <br />they are of limited scientific value. <br />Threatened and EndanReced Plants <br />The Lease application area has not been inventoried. There are no known <br />threatened and endangered plants or habitat suitable for those plants in <br />the area. <br />Floodplains <br />The Colorado Hined Land Reclamation Division in their Proposed Decision <br />and Findings of Compliance dated February 1986, stated that based on Red <br />Wash and its associated alluvium the area meets the geomorphic criteria <br /> <br />13 <br /> <br />
