Density data was estimated from two meter wide belts, one meter on each side of <br />the cover transect. Woody plant hits were recorded at the same time as cover data. Only <br />two woody plants were recorded during the study, one each in areas Sl and S3. <br />Ten production plots measuring one square meter in size were clipped in each of the eight <br />sample units. Clipped vegetation was then separated into its growth form, either perennial <br />' or annual, and stored in paper bags. The production samples were weighed, providing the <br />'rvet weight" data appearing in Tables 4 and S. The bags of vegetation were then dried for <br />24 hours at 105 degrees Fahrenheit, after which they were weighed once more, providing the <br />' "dry weight" data also appearing in Tables 4 and 5. <br />' Sample adequacy for the production plots was calculated using the Snedecor-Cochran <br />sample adequacy formula (Equation 1). The total weight of each production sample (weight <br />of perennial plus weight of annuals) was used in the sample adequacy formula. Data for <br />' both the wet and dry weights were run through the formula, resulting in only one area being <br />sampled to adequacy; plot S2 (dry). Tables 6 and 7 presents a summary of the total weight <br />for each production plot and the minimum number of samples that would have been needed <br />' to reach sample adequacy. <br />Results <br />' Since the seeding of the reference plots was completed in the late summer of 1990, the 1993 <br />' vegetation samp]ng occurred toward the end of the third growing season.
