Vegetative litter (prior years growth, dead wood, and other biologic organic material) <br />comprised an average 60.00% ground cover within the reference area. Bare soil <br />j comprised 15.00% of the ground cover encountered in the reference area. <br />Herbaceous Production <br />Total herbaceous production on the Osgood Sand Reference Area was 58.25 g/m2 <br />(519.23 lb/ac). Perennial grasses dominated reference area herbaceous production, <br />composing 51.55 g/m2 (459.50 lb/ac) or 88 percent of total herbaceous production. <br />No annual grasses contributed to herbaceous production in the reference area. forbs <br />accounted for 6.71 g/m2 (59.81 lb/ac) of the reference area herbaceous production. <br />Annual forbs provided 6.47 g/m2 (57.67 lb/ac) or 1 l percent of the total production. <br />Perennial forbs accounted for 0.24 g/m2 (2. I lb/ac) or less than one percent of the total <br />herbaceous production in the reference area. <br />Species Diversity <br />Within the reference area three lifeforms were represented. The total number of <br />species encountered during cover sampling within the reference area was seven (7). <br />Graminoids accounted for five species, forbs one species, and shrubs one species. All <br />of the species encountered on the reference area were native. Perennial species <br />• outnumbered annual species by six to one. Of the species encountered, three <br />represented greater than three percent relative cover; Artemesia iilifolia (71.00%), <br />Stipa comata (14.87%), and Andropogon hat/ii (6.69%). <br />Seasonality of the reference area was dominated (in total numbers) by warm season <br />species, but also included cool season and evergreen species. Graminoids were <br />dominated in seasonality by warm season species with four warm season species and <br />one cool season species present in sampling. The forb species was identified as warm <br />season. The shrub species was evergreen. <br />1985 RECLAMATION AREA <br />l The 1985 Reclamation Area encompasses approximately 18.6 acres of reclaimed pit in <br />the north central area of the Keenesburg Mine permit area. The 1985 Reclamation <br />1 Area is composed of two parcels (west and east) separated by a north-south haul road <br />corridor. This azea is nearly flat with a gentle slope (< 1 °) to the north and east. <br />Reclamation and coincident revegetation within this area took place in 1985. Replaced <br />soils were generally sandy in texture. The revegetated areas within the 1985 <br />Reclamation Area varied to a minor degree from more recently reclaimed areas in the <br />degree of presence of cool season graminoids. Specific sampling information for the <br />1985 Reclamation Area is contained in Table 3 and Table 7. <br />• <br />-6- <br />
