<br />Species Diversity: <br />For a Phase III bond release request, multiple hit data (first, second, third...) will <br />be used to evaluate species diversity success. However, for the purposes of a <br />Phase II bond release request, species diversity will be evaluated using only <br />first-hit data since first hits generally far exceed all other vegetative hits combined <br />(especially with a herbaceous dominated vegetation). The diversity is checked in <br />accordance with the Division's Bond Release Guidelines, to assess the progress of <br />revegetation to determine if sufficient number of species are being established. <br />Herbaceous Productivity: <br />Production plots will be I/2 meter by 1/2 meter in size unless otherwise agreed <br />upon with DMG. All current herbaceous production inside the production plots <br />will be clipped, separated according to life form, and bagged. The four life forms <br />will include perennial grasses, perennial fortis, annual species, and noxious weeds. <br />Production data will not be the basis of species diversity, and therefore sorting by <br />species is unnecessary. All production samples will be oven dried at 110 degrees <br />Fahrenheit to a constant weight. Sample adequacy calculations will be based on <br />total herbaceous production. Comparisons between reclaimed and reference areas <br />will be based on total non-noxious, perennial herbaceous production. Noxious <br />weed, annual, and biennial species production will not be included in the <br />companson. <br />Woody Stem Density: <br />Woody stem density will be evaluated by counting the number of shrub and tree <br />individuals rooted within 50 meter by 1 meter elongated quadrats. The number of <br />individuals within each quadrat will be tallied by species. <br />Sample Adequacy and Statistical Evaluations: <br />For each parameter, a statistically adequate number of samples will be collected in <br />determining reclamation success. Statistical methods and formulas will be <br />consistent with those outlined in the Division's latest version of the Bond Release <br />Guidelines. Statistical tests will comply with requirements set out in Rule <br />4.15.7(2)(c). Prior to sampling, the operator will discuss sampling methodology <br />and statistical analysis procedures with the Division. <br />4. Eliminating the Riparian designation for the Lower Hubbard Creek (LHC) site. <br />The original baseline survey indicated that the Lower Hubbard Creek area's <br />undisturbed vegetation was part mountain shrubland (MS) and part juniper <br />woodland (JW) although the boundary of the disturbance is very close to Hubbard <br />Page 3 <br />
