<br />i <br />• <br /> <br />1. Permit Map No. ~? has been revised clearly delineate the boundary <br />between the pinyon-juniper and bottomland vegetation crommunities. <br />An area separating two areas of bottomland vegetation was <br />essentially barren of vegetation and therefore was not sampled. <br />2. Adequate sample size for woody plant deruity was calculated using <br />the formula nmin - t~ j2where <br />nmin -minimum sample size <br />s .sample standard deviation <br />z .sample mean <br />d = 0.1 <br />t .1.282 for woody habitats (pinyon -juniper) <br />1.643 for herbaceous habitats (bottomland) <br />Distance values for each of the 40 quarters along the 10-point <br />traruects (!0 in pinyon-juniper and 3 in bottomland) were averaged to <br />determine the average distance for each transects. Sample standard <br />deviation was calculated from these transect averages.

Qualitative Description of Vegetation Communities. <br />Bottomland <br />The vegetation community designated as bottomland occurs within <br />the loamy foothill range site as defined by the Soli Conwvation <br />Service. Typical (climax) vegetation of this area !s believed to have <br />been as g ass am l class amt d d nuo hated by blue grama~ with other grasses and <br />~forbs~and shrubs (including snakeweed) occuring in lesser amounts. <br />This type of community typically occurs at lower elevations near <br />pinyon-juniper woodlands, and often intergrades with them <br /> <br />233 <br />
