A sample size adequacy test was <br />performed on existing condition data to determine minimum sample size <br />needed to accurately reflect existing habitat conditions. It was <br />determined that one third of the contracts represented an adequate <br />sample'size (P~0.05). Beginning with FY 94 contracts, one third of <br />funded contracts will be randomly selected and ,evaluated with the HEP <br />process. <br />Applied conditions are evaluated following completion of the <br />contract and again after 3 additional years. <br />changes between existing, planned and applied <br />,measured in terms of Habitat Unit Values (HUV's). <br />calculated by multiplying the HSI,for each species <br />cover types utilized by each species. <br /> <br />conditions are <br />HUV's are <br />by the acres of <br /> <br />Monitorinq Sites <br />Twenty contracts have been randomly selected (from those funded <br />through FY 93) for annual HEP analysis. The data gathered from these <br />contracts (monitoring sites) will be evaluated each year for the life <br />of the contracts. Analysis of these data will attempt to look at <br />short term effects and determine cause of habitat changes resulting <br />from individual salinity practices. <br /> <br />Off-Site Wetland Monitorinq <br />Off-site monitoring is being conducted by inventorying wetlands <br />on true color aerial photographs. Flight line transects spaced one <br />mile apart running east and ,west for the entire project area were <br />established. From these transects, within the project boundary, 49 <br />miles of designated flight lines were randomly selected and flown., A <br />total of 54,000 acres and 32% of the project area are represented by <br />the photographs. Each photograph represents ,about 1.5 square miles. <br />The photographs were taken in August of 1991. Wetland inventories <br />have been completed on the 1991 photos. These transects will be flown <br />on 5 year intervals and ground truthed to monitor and evaluate changes <br />in wetlands. The next wetland inventory will be in 1996. <br /> <br />Additional Wetland Inventorv <br />Wetlands identified within salinity contracted acres and any off- <br />site wetlands that are expected to be impacted, are inventoried on all <br />salinity contracts. The location, size, type, source of'water <br />supporting the wetland (i.e. irrigation induced or natural wetland), <br />and value of wetlands are determined and tracked. Wetland values are <br />quantified with the Colorado SCS Wetland Evaluation Procedure (CWEP). <br />Wetland unit values (WUV's) are generated by multiplying acres of <br />wetland by the estimated value for the wetland. This value is based <br />on an evaluation of wetland functions using eWEP and expressed on a <br />scale of 0.0 to 1.0. <br /> <br />21 <br />
