A checklist of the bent:~ic :nn croinvertebrate taxi n~~llected <br />• from Foidel Crc~l: is prc.cntod in Tab1c 23, along ~:ith [hc <br />number of each Cason by station. Summary of the date and <br />diversity at each station are presented in Table II-4. <br />lJater flow and scream width at both stations in Foidel Creek <br />on September 8, 1975, ware insufficient to allow t;ie <br />collection of benthic organisms. Therefore, the discussion <br />that follo~:s reflects only t~ao benthal samples fro- this <br />drainage. <br />The total number of individuals increased in the d~:.~nstream <br />' direction (Table 22). The most significant faunal Chang=_ <br />was the increase in importance of Dipcera ac the le::er s~a- <br />tion, which accounted for approximately SS percent cf the <br />organisms collected at the upper station on Foidel Creek. <br />• This increased to approxi.;.at_ly 79 percent at the lower sta- <br />! tion. The faunal change bet~.•een stations probably resulted <br />from differences in the substrata, the abundance o` aquatic <br />macrophytes, and possible change in various physica'- an3 <br />I, chemical parameters. Among the latter, temperature, water <br />.' velocity, pH, dissolved oxygen, total dissolved so:'_ds, and <br />importance of shading commonly influence the benthic com- <br />e <br />munity (Hynes 1960, 1970). <br />Threatened and Endangered Species <br />The lease application areas do nnc contain an)• T/E species <br />nor will the tract affect ary T/E species do~mstrea:n. <br />4.
