^: '". <br />.4 , <br />H-G Mine <br />Permit No. C-80-003 <br />b) Herbaceous Production <br />Production data will be collected from meter square quadrats. <br />All current year above-ground herbaceous plant biomass (except <br />for annuals and noxious weeds) rooted within the plots will be <br />clipped. Samples will be separated by life form and will not <br />be species specific. Production data for woody plant species <br />material will not be collected. A minimum of 15 samples will <br />be collected on the reclaimed area and a minimum of 10 samples <br />will be collected on each of the reference areas. Sampling <br />will continue until adequacy is met in accordance with the <br />formula presented in the 1988 DMG Vegetation Guideline or <br />until a maximum of 50 samples are collected. <br />c) Shrub Density <br />The density of shrubs will only be calculated for samples in <br />the reclaimed area and data will not be collected on the <br />reference areas. Sampling will consist of counting all stems <br />protruding from the ground within belt transects two meters <br />wide by 50 meters long. A minimum of 15 samples will be <br />collected on the reclaimed area. Sampling will continue until <br />adequacy is met in accordance with the formula presented in <br />the 1988 DMG Vegetation Guideline or until a maximum of 50 <br />samples are collected. <br />d) Species Diversity <br />Data for species diversity on the reclamation will be <br />obtained directly from the herbaceous cover figures. A list <br />of plant species noted in samples and observed during the <br />course of field work will also be compiled. <br />4) Bond Release Criteria <br />a) Herbaceous Cover <br />The mean of absolute cover for herbaceous plants from the <br />reclamation will be within 90$ or greater of the weighted <br />mean of absolute cover for herbaceous plants on the reference <br />areas with 90$ confidence using the one tailed t-test. Cover <br />of noxious weeds will not be counted toward the success <br />standard. Annual or biennial plant species will contribute no <br />more than iD~ of the relative cover figures toward bond <br />release. <br />2 <br />
