The malrimnn height <br />of each shrub enwuntered in the quadrats was rewrded in inches with a <br />stick ruler. <br />All cover, frequency and shrub height data were collected during the <br />period AID 1St z7 rlrou3n sepce~er 7, 1979. The vegetati~ types sac~led <br />for cover, productivity, frequency and shrub height are depicted on the <br />Map entitled "Vegetation Types" in Appendix A. . <br />Field Techniques. Circular wire exclosures, approximately 1.Sm in diameter <br />acrl 1.Sm high, were situated at each sample point during early May, 1979. <br />Dcamstic livestock were kept off the study area until exclosures were es- <br />tablisned. All enclosures were constructed of 2x9 inch mesh wire to pre- <br />vent grazing by all medium-sized (i.e., rabbits) a~ large m~mnals. F~cclo- <br />sores were supported by k inch steel reinforcing rod and labeled. as <br /> <br />(Revised March 2006) Attachment 2.05.6(2)-'(-14 <br />
