' Pikeview Quarry Environmental Assessment Page 19 <br />Revegetation Monitoring Plan for National Forest System Lands <br />' Species cover and shrub and tree density will be monitored to measure the plant <br />growth and density and to evaluate the success of reclamation efforts. Monitoring activities <br />will take place until performance standards are reached. <br />' Compliance will be determined by written opinion of the Colorado State Weed <br />coordinator with reference to the current Colorado lists of prohibited and restricted noxious <br />weeds. <br />a) Locations <br /> Following seeding /planting, 13 to 26 transects8 (one per acre) will be permanently <br /> established on the "benches". These will be 50 m in length with ends mazked with <br /> fiberglass poles (for visual evidence) as well as rebar driven flush with the ground (for <br /> "visibility" to metal detectors). Endpoints will be hand surveyed from set locations for <br /> future relocation reference. <br />' b) Cover Data <br /> Cover data will be collected using a point intercept method in which data will be <br /> recorded as interceptions of a point with plant species, litter, standing dead plant material, <br /> soil or rock. Plant material produced during the current growing season and still standing <br />.~ will be tallied by species. Litter will be considered to be any organic material that has <br />fallen, or begun to fall to the soil surface. Standing dead will be any dead plant material that <br /> was produced in previous years but which is still standing and has not lodged or broken off <br /> to become litter. Inorganic materials greater than 1 cm in diameter will be considered rock. <br />The cover sampling points will be optically projected using an optical point projection <br /> device. One hundred points will be collected randomly at each transect. <br /> The point intercept method of cover assessment is specified because it provides <br /> superior objectivity and repeatability. This method collects more information about <br /> abundant species than about raze species. This inherent tendency is countered through use <br /> of a total vasculaz species inventory along the sample transect (see "Species Diversity"). <br /> c) Species Diversity (Density) <br />' <br /> A full accounting of all plant species encountered within each of the azeas sampled <br /> for cover will be compiled. Along point intercept transects, species presence will be noted <br />' within the azea one meter to either side of the transect (SOm x 2m = 100 m2). These presence <br /> data along with point-intercept data themselves will be used to produce values for vasculaz <br /> plant species density expressed on a per 100 sq. m. basis. <br /> <br />8 Depending on how much National Forest System land is used for the layback. <br />Hydrosphere Resource Consultants, 1002 Walnut Street Suite 200, Boulder, CO 80302 <br /> <br />
