Sampling Parameters <br />Cover: Terms for purposes of monitoring and bond release will be defined as follows: <br />First -Hit Plant Cover. Percent of the ground surface covered in vertical view by living plant <br />parts (parts living at the time of observation plus attached parts that were produced during <br />the current growing season). These data add up to 100 percent and plants beneath other <br />plants in vertical projection are ignored. With respect to the point - intercept method of cover <br />sampling, "first -hit" data include only the uppermost hit at each point projection location. <br />All-Hit Cover. Percent of the ground surface covered by all living plant parts without regard <br />to whether they are overlapped by other plant species. All plant species "hit" in vertical <br />projection of a sampling point, even those beneath other species, are named and count <br />toward the percent cover reported. When all plant species present are considered, these data <br />may add to more than 100 percent. With respect to point - intercept cover sampling, "all-hit" <br />data account for interceptions of a projected point with all species, whether or not they were <br />the first encountered in the vertical descent of the point. Note that multiple hits on the same <br />species are not named. <br />Herbaceous Species. Plant species in the native annual and biennial forbs, introduced <br />annual and biennial forbs, native annual grass, introduced annual grass, native perennial forbs, <br />introduced perennial forbs, native perennial cool - season grasses and grass -like, introduced <br />perennial cool - season grass, and ferns life forms. Subshrubs, shrubs, and trees are not <br />included. Fungi, mosses, lichens and algae are also not included. <br />All-Hit Total Herbaceous Vegetation Cover. Summed percent cover of all herbaceous <br />species encountered based on "all-hit" data. <br />Cover data will include "first -hit" and "all-hit" cover by species (both absolute and relative values), <br />total vegetation cover and cover values for litter, rock, and bare ground. If present, cover by mosses <br />and lichens will also be tallied. <br />Production: Production data will be collected as total current year's herbaceous standing crop <br />biomass. In sampling for bond release, harvested biomass will be separated by life form. Shrub or tree <br />• production will not be sampled. Values will be expressed as gm per 0.5 sq. m. and lbs /ac. <br />TR -65 41 Revised 9/09 <br />
