3.1.4 1998 RESEEDED OR INTERSEEDED AREAS <br />• The 1998 reseeded or interseeded areas sampled this year encompass 34 acres of <br />reclamation in five distinct areas within the Keenesburg Mme permit area. The areas <br />include Area 2, an area immediately west of the dugout, Areas 7 and 10, two areas south <br />and east of the central 1987 area, Area 15, west of A pit and bordered on the west and <br />south by undisturbed range, and Area 26, south of the sediment pond. Vegetation cover <br />transects and herbaceous production quadrats were distributed within the five areas based <br />on size. The 1998 reseeded or interseeded areas range from flat (Areas 2, 7) to north and <br />south sloping (Areas 15 and 10, respectively). Reseeding or interseeding with the <br />permanent seed mix took place during the autumn of 1998 within these areas with the goal <br />of increasing perennial graminoid representation. Area 10 was burned in the spring of <br />2003 to control a stand of Bromus tectorum. Regrowth by warm season perennial grasses <br />had begun, but had been somewhat hampered by a lack of mid-season precipitation. <br />Rather than bias the sampling by including the low cover and production area, Area 10 <br />was omitted from sampling this season. Specific sampling information for the 1998 <br />reseeded or interseeded areas is contained in Tables 8 and 9. <br />3.1.4.1 Vegetation Cover <br />Total vegetation cover of the 1998 reseeded or intersceded areas was 40.67 percent. <br />Graminoids provided 29.67 percem mean cover (76.73% relative cover), forts accounted <br />for 10.33 percetrt mean cover (22.01% relative cover), one succulem cornributed 0.33 <br />• percent mean and 0.63 percent relative cover, and one shrub contributed 0.33 percent <br />mean and 0.63 percent relative cover. Total cover values were variable between the <br />individual areas within the 1998 reseeded or interseeded areas. The lowest total vegetation <br />cover of the parcels sampled was found in Area 2 (22%) and the highest cover was <br />encountered in Area 15 (58%). Kochia scoparia and Helianthus atmuus were <br />encountered in all the reseeded or interseeded area parcels, with Kochia scoparia in 83 <br />percent of all transacts and Helianthus annuus found in 67 percent of all transacts. <br />Bromus tectorum was encountered in three of the four parcels and in 83 percent of all <br />transacts. <br />Within the 1998 reseeded or imerseeded areas, Bromus tectorum accounted for the <br />highest overall cover with 15.67 percent mean cover and 42.77 percent relative cover. The <br />coo] season annual fort Kochia scoparia contributed the second highest cover values with <br />8.00 percent mean cover and 17.61 percent relative cover. Five additional species <br />contributed significantly to cover; Sporolwlus cryptandrus with 4.00 percent mean cover <br />(9.43% relative cover), Agropyron intermedium contributed 3.00 percent mean and 6.92 <br />percent relative cover, Bouteloua curtiperrdula provided 2.00 percent mean total cover <br />and 6.29 percent relative cover, Calmnovilfa lottgifolia with 1.33 percent mean and 3.77 <br />percent relative cover, and Helianthus annuus wntributed 1.67 percent mean cover <br />(3.14% relative cover). <br />r~ <br />L.
