comributed the least to annual herbaceous production in this azea this yeaz (0.08 g/mz or <br />• <1 ib/ac). Biennial forts did not contribute to total herbaceous production this season. <br />3.1.5.3 Species Composition <br />Cover sampling idemified two lifeforms and 11 species within the 1999 reclamation aeeas. <br />The lifefonns included six species of perennial graminoids, one armual grass, one perennial <br />fort, and three annual forts. Of the species encountered on the 1999 reclamation areas, <br />seven were native and four were introduced. Perermial species outnumbered annual <br />species by seven to four. Cool season species were more prevalent than wazm season <br />species (7 to 4 species) this yeaz in the 1999 reclamation aeeas. Warm season graminoid <br />species accounted for three species and cool season species included four species. Three <br />fort species were identified as cool season and one was warm season. <br />The 1999 reclamation areas had six species contributing greater than three percent relative <br />cover this yeaz. These species included Kochia scoparta (30.12%), Calamovilfa <br />Iongijolia (18.07%), Ambrosia psilostachya (13.25%), Helianthus aromas (12.05%), <br />Bromus tectorum (9.64%), and Agropyro» smithii (8.43%). <br />3.2 QUALITATPYE EVALUATION: <br />1985,1986,1987, 2000 AND 2002 RECLAMATION AREAS <br />3.2.1 1985 RECLAMATION AREAS <br />The 1985 reclamation areas encompass appro~amately 23 acres of reclaimed pit in the <br />north central area of the Keenesburg Mme permit area. The 1985 reclamation area is <br />composed of two pazcels (Areas 13 and 22) separated by a north-south haul road corridor <br />(Area 19). This azea is nearly gat with a gentle slope (<2°) to the north and east. <br />Reclamation and coincident revegetation within this area took place in 1985. Replaced <br />soils were sandy in texture. The revegetation seed mix differed slightly in composition and <br />representation of cool season grasses from the seed mix applied to the 1986 and 1987 <br />reclaimed areas, yielding a slightly different species composition. <br />Area 13 was mowed in the autumn of 2003 to reduce standing dead litter. Observations <br />of the parcels during sampling and at the end of the growing season indicated significant <br />growth this season, particularly in the cool season graminoid wmponent. Several fort <br />species were observed. Plants appeared healthy in the 1985 reclamation areas, with good <br />whn and root vigor. Total mean vegetation cover was estimated between 50 and 55 <br />percent throughout both Areas 13 and 22. Herbaceous production of this area was <br />estimated at 150.200 g/mZ (1340.1780 Ib/ac). There was no evidence of invasion by <br />unwanted species or evidence of pest or disease problems. <br />r~ <br />\_J <br />CooreEnergyCompary Page 14 <br />2A08 Revegetatbn Monkoring Report <br />
