Attachment 2.05.4(2)(e) - 5 <br />Summary Tables of 2007 Sampling for Production and Cover, Irrigated Pasture <br />Reference Area <br />Sampling for production and cover was done in June 2007 by BIO-Logic Environmental, Steve <br />Boyle, Principal Investigator. For production, all current year above-ground vegetation was clipped <br />in a randomly-placed 0.25-m2 sample frame. Sampling was terminated without reaching sample <br />adequacy after 44 sample observations (mean of desirable vegetation = 2.512.5 lb/acre, standard <br />deviation = 1,726.3, estimated number of samples for adequacy = 80). The following table shows <br />mean production estimates for plant life forms. <br />n <br />ant Life Form (lb/acre) <br />sirable Perennial Grasses 2,436.1 <br />sirable Perennial Forbs 0 <br />rub 76.4 <br />Total Desirable Plant Production 2,512.5 <br />ndesirable Annual Grass (Cheatgrass) 1.1 <br />ndesirable Annual Forbs (non-native annual weeds) 153.2 <br />oxious Weeds 9.7 <br />Total Undesirable Plant Production 164.0 <br />Cover was sampled using a laser point frame on randomly-placed 100-foot transects, <br />making 10 first-hit cover observations perpendicular to the transect at each 10-foot interval <br />on the transect. Sampling was terminated after 15 sample observations (mean cover of <br />desirable plants = 68.6%, standard deviation = 23.2%, estimated number of samples for <br />adequacy = 21). The following table shows estimates of mean absolute cover and relative <br />cover (absolute cover as percentage of total vegetation cover). <br />(Revised Oct 08 TR 58) 2.05.4(2)(e) - 62 <br />9ppr )3MOV &09
