<br />-30- <br />~~ <br />7'tve fort stratum evidenced the highest production 569.3 lbs/acre or 69.88 <br />of the mtal production; grasses contrituted 245,8 lbs/acre production <br />(30.28). Most of the identifiable forts in production samg~les were reed <br />species including field bindweed, bur]clarn plantain, Idissian knap~ <br />(Centaurea xE )and mrcrron bluemistard. As with other rover sartples, <br />wheatgrass arri bronie species were well r'Bpresented in production samples. <br />Tbtal percent croisture in production samples collected was 32.98 for <br />forts and 36.48 for grasses. <br />The grassland reference area was situated on a 2.2 acre site not to be dis- <br />turbed by future mining activities (Map entitled "Vegetation Types", Appen- <br />_ dix F~. Only 10 species were enm~mtered in cover quadrats and as a result, <br />the species diversity Sndex was low. 1.45. <br />Tbta1 Doves (vegetation plus bare ground plus litter-roc3c) for the grass- <br />land mfererce area was estdmated at 75.38.

Stickseed (~La texana) <br />and scarlet globemallow (Slohaeralcea ooccinea) were carrion forts in rover <br />quadrats accounting for 41.3 and 21.78 of the total fort roves, respectively. <br />Freque:ry values for these two species were 68.38 and 40.08, respectively. <br />Brown snakeweed (~ sub-shrub).
