<br />1999 FRE4UENCY/DENSITY DATA FOR 1998 RECLAMATION AREAS <br />LOCATION: Colowyo Coal Co., L.P. Meeker, CO <br />SAMPLER: L. VanAmburg and V. Williams <br />Frequency data was collected in early July for the 1998 reclamation areas. The <br />Frequency/Density method was used as the sampling technique to represent the <br />frequency of species present in the 1998 reclaimed areas. This sampling procedure <br />includes the random placement of a 60cm X 60cm square plot. After each placement, <br />the plant species present inside the plot was recorded (see attached data sheets). <br />Reclaimed areas were divided into Section 11 and Section 16. In each area 250 <br />random placements were conducted for a total of 500 placements. Throughout each of <br />the two areas, the placements were then divided accordingly between acreage. <br />Data was collected and compiled onto a spreadsheet (see Tablet and 2). Each <br />table lists the top twenty most abundant species, number of hits out of 250, frequency, <br />and density. The frequency and density numbers were determined statistically based <br />on 250 random placements using apre-calculated frequency/density table at a 90% <br />confidence interval (CI). <br />
