Prairie sandreed
There is no question that the most outstanding
species used in reclamation seedings at the Keenesburg Mine
is Prairie sandreed. This is supported by the strong,
co-dominant position it has in the climax vegetation of the
Deep Sand Range site of the Central High Plains . Prarie
sandreed produced 27 . 6 per cent of the cover and 46 per cent
of the biomass in the ' 85 RA and 11 per cent and 8 per cent
in the more recent ' 86 RA. The strong rhizomatous habit with
copious seed production, almost from the outset of its
growth, give this sandy land grass tremendous advantages in
the establishment of vegetative cover. Seed originating
from as near as possible to the site will be even more
favored for planting than the "Goshen" selection.
Sand bluestem
Standing with Prairie sandreed as a co-dominant
in the Deep Sand range site , Sand bluestem should be relied
1
on for becoming a major grass of the reclaimed areas at the
mine . Sand bluestem produced 24 . 9 per cent of the cover and 11
per cent of the biomass on the 1988 Reference Area. The
low rating Sand bluestem had in the ' 85 RA with a three
per cent of the cover and only two percent of the biomass is
difficult to understand unless itcan be blamed on poor seed v
quality , to distant seed origin, or faulty planting technique.
Sand bluestem had still lower grades in the ' 86 RA where
it was no more than 1 . 7 and 1. 0 percent respectively for
cover and biomass . Otherwise there is little reason to question
