' - lU4 - <br />The production measurements will be obtained on a few <br />of the visually dominant species and the remaining measure- <br />, ments will be taken by lumping the remaining species into <br />life form categories. The life form categories to be used <br />' are as follows: annual grasses; cool season perennial <br />grasses; warm season perennial grasses; annual forbs and <br />perennial forbs. The samples obtained in the fleld will be <br /> returned to the lab for drying and weighing. The samples <br /> will be dried at 100oC for a period of 24 hours and then <br />' weighed. <br /> The Snedecor-Cochren sample adequacy equation will be <br /> <br /> used also to determine if an adequate number of samples were <br /> obtained to give a statistically reliant estimate of the mean <br /> and variance for the characteristic, The procedure to be <br /> followed to assess sample adequacy for production measurements <br /> will be the same as that for cover. The final outcome will be <br />1 <br /> a demonstration of sample adequacy. <br />Density <br />Woody species density will be obtained by establishing <br />' 10 m2 quadrants randomly over the sampling area. At a minimum <br />' 20 quadrants will be established and the woody species density <br />for each quadrant will be measured. Additionally, the density <br />' of each woody species will be noted and used to compare the <br />density values per species per unit of area. <br />' Each quadrant will be started at the beginning of each <br />line transect which has been randomly selected. The orientation <br />1 <br />
