Since the clipping for <br />interim monitoring does not separate the annuals from perennials, the exclusion <br />of annuals from allowable production is not known. It is thought that certainly no <br />more than one-third (and probably quite a bit less) of observed total production <br />would be disallowed, still leaving plenty to exceed 90% of the standard. <br />Woody Plant Density <br />2005 data from the 1998 reclaimed area indicate the presence of about 1299 <br />woody plant stems per acre.
