•
crassus (Payson lupine) could possible occur on the site. Payson lupine is a U.S. Fish and
Wildlife Service category 2 species. Category 2 species are candidates for listing as
endangered or threatened for which additional data are needed before listing can proceed.
Thorough searches of the study area, including searches of likely microhabitats, failed to
produce any specimens of Payson lupine. The searches also failed to produce any other plant
species of special concern. The results indicate that it is extremely unlikely that any such
species occur in the study, or proposed permit area.
A number of Colorado designated noxious weeds were found during the 1987 vegetation
surveys. The presence of these noxious and restricted weeds is not unexpected due to the
intensive agricultural activities and large amount of disturbed and abandoned areas within the
study area. There were four prohibited noxious weeds encountered during the studies. They
are:
Field bindweed
Jointed goat grass
Canada thistle
Hairy whitetop
(Convolvulus arvensis)
(Aegilops cylindrica)
(Cirsium arvense)
(Cardaria pubescens)
In addition five restricted noxious weeds were also found. They are:
Curly dock
Blue lettuce
Buckhorn plantain
Poverty sumpweed
Quackgrass
(Rumex crispus)
(Lactuca pulchella)
(Plantago lanceolata)
(Ira axillaris)
(Agropyron repens)
The above noxious weeds were determined from Appendix B to OMLR's draft "Guidelines for
Compliance with Land Use and Vegetation Requirements for Coal Mining".
