seen in the width SSD, but those results are not presented here. This large height SSD supports the <br />conclusion that the woody vegetation in Exclosure 1 is in a rapid state of change. In a word, it is yet <br />to be decided who will occupy what space. <br />Cover: Cover values were determined by the proportion of the total transect area that was <br />occupied by the total of the projected area of the woody plants. Projected area was determined by <br />multiplying the square of half the mean diameter of each plant by pi. Although cover has visibly <br />increased compared to 2006, cover in the exclosure remains at less than 5%. Although the calculated <br />cover as shown in the table is about 1.5 to 2.0 percent, to be statistically fair this should be stated as <br />less than 5% because such low values as 1 or 2 percent are not very reliable. For now, suffice it to <br />say that although the numbers of plants in the exclosure is excellent, they really don't contribute <br />much to the overall cover of the vegetation. Herbaceous species account for nearly all the cover at <br />this time. <br />TABLE 1: Exclosure Analysis Results for 2007 - Exclosure 1 (most southerly) <br />parameter Transect 1 <br />(most <br />northerly) Transect 2 <br />(middle) Transect 3 (most <br />southerly) All Transec[s All Woody <br />Plants <br />ttl transect ingth 145 feet 142 feet 139 feet 426 feet 426 feet <br />veg transect ingth 114 feet 133 feet 82.5 feet 329.5 feet 329.5 feet <br />transect width 6 feet 6 feet 6 feet 6 feet 6 feet <br />ttl transect area 870 sq ft 852 sq ft 834 sq ft 2556 sq ft 2556 sq ft <br />veg transect area 684 sq ft 798 sq ft 495 sq ft 1977 sq ft 1977 sq ft <br />Papu[us Populus + Salix <br />number 54 23 10 87 282 <br />mean height (in.) 14.93 30.3 36.1 21.425 26.855 <br />max height (in.) 46 65 54 65 65 <br />min height (in.) 8 10 20 8 8 <br />height SSD** <br />(inches) 8.661 12.279 11.618 13.099 11.304 <br />cover 1.274 1.694 2.128 1.657 8.04 <br />density 1* <br />(plants/acre) 2704 1176 522 1483 4806 <br />density 2* <br />(plants/acre) 3439 1255 880 1917 6213 <br />2007 Annual Report Coal Creek Wetland Mitigation Permit DA 198811488 Page 9 <br />
