Swale, and 10 samples from two unprotected swales, for a grand total of 100 0.1-square- <br /> meter plots during each sampling period, as described above for vernal pools. <br /> Marsh. Vegetation monitoring shall take place in the following marshes: <br /> o all created marshes (Marshes 53-56), and <br /> o selected protected marshes (Marshes KK, MM, NN). <br /> All affected marshes will be filled during the initial construction activities and, therefore, <br /> will not be sampled for comparison. The locations of the created and protected marshes <br /> are shown in Figure 6; the location of the marshes to be filled are shown in Figure 2. <br /> Ten samples will be taken from four created marshes and 10 samples from three <br /> protected marshes for a grand total of 70 1.0-square-meter square plots during each <br /> sampling period. Sampling should be conducted during the flowering season of the <br /> dominant marsh species (summer). Timing of the quantitative sampling should be <br /> determined during spring surveys for the vernal pools and swales, based on water levels and <br /> climatic conditions (i.e., drought). Species composition and percentage of total cover by <br /> each species shall be recorded in 10 randomly located 1.0-square-meter square sample plots <br /> at or near the bottom of each marsh and 10 randomly located 1.0-square-meter square <br /> sample plots at the margin of each marsh. (The plot size can be modified depending on the <br /> conditions of the vegetation; however, plot size and number should be consistent from year <br /> to year for statistical validity.) All other sampling methods shall be as described above for <br /> vernal pools. <br /> Grassland. Vegetation monitoring shall take place in the following grassland areas: <br /> o created grassland (Mitigation Sites C, D), <br /> o protected grassland (Mitigation Site A), and <br /> o unprotected grassland(southwestern and southeastern portions of the landfill). <br /> The locations of the created and protected grasslands are shown in Figure'6; the location <br /> of the grassland to be filled is shown in Figure 2. This list of monitoring sites is subject to <br /> change so that specific,unforeseen monitoring needs and opportunities may be incorporated <br /> into the monitoring design. <br /> Data on species composition and cover shall be collected in those sites identified <br /> above once each year (April to early May) during the flowering period of the dominant <br /> grassland vegetation in the same manner as described for vernal pools. A total of 10 <br /> samples will be taken from four created grassland sites and 10 samples from five protected <br /> grassland sites for a grand total of 90 0.1-square-meter plots each sampling period. <br /> 55 <br />
