Attachaent 2 <br />Casper Creek lmNS (SEPA /92-89) <br />Page 4 <br />Baalc Propram Guldel►nea: <br />1) Standard methods for collection of data and its analysis shall be used. These <br />methods shall bo taken from published literature on other westem Washington <br />Palustrine scrub/shrub wetland/wedand ecosystems. The most important <br />considerations shall be: <br />a) Type oi gear used to collect organisms. <br />b) Time of sampling. Since water level, moisture, temperature, lipht levels, and <br />nutrient input varies seasonally in PalusUine sc►ub/shrub weUands, care must be <br />taken to schedule sampling at the same time of year. <br />c) Size of sample unit. For example, the quadrant unit for sampling vegetation <br />must be kept the same size. <br />d) Location oi samp�ing station. If sampling stations in a natural and restored <br />PalusUine scrub/shrub wetland ecosystem are to be compared they must be <br />surveyed to esteblish elevation above the sVeambed, since species composition <br />in a PalusUine scrub/shrub wetland ecosystem can change siqnificantly with <br />elevation changes. <br />2) Moni►or a broad renge of stiuctural and functional components within the Palustrine <br />scrvblshrub weGand ecosystem that are general indicators of Palustrine <br />scrub/shrub weUand condition. <br />3) Obtain annual air photas of the study area in order to detertnine overall chanpes in <br />the Palustrine saub/shrub wetland cortidor. From these photos identiry where <br />species composition mey be changing relative to the baseline vegetative survey <br />conducted for this report, and tradc and assess erosion, sedimentatlon in the <br />wetlard/creek, and land use changes adjacent to the wetland/creek study area. <br />
