germination of seed will occur over a longer period of time. This will allow other species in the reclamation mix an additional edge in • establishment and growth. Finally, crosses between Medic:a o sativa and Medicago falcata tend to result in sterile hybrids. This may partially aid in controlling the excessive establishment of additional alfalfa plants over time. Information related to Medica o falcata is not extensive even though this species was the basis for the first alfalfa varieties developed in the U.S. many years ago. The information presented above was developed from the attached information and discussions with Dr. Courrier of the Alfalfa Laboratory at New Mexico State University, Las Cruces, IJew Mexico. COMFIENT: A.3. Comment nine (9) of the PAR dealt with the lack of shrub individuals and the potential long term problems associated with C achieving woody plant density. PCC broke its reply into two areas: • The measures that have been implemented to date; and, the measures proposed for the future. The measures implemented to date have been a continual increase in shrub species planted and modifications to the seed mixture to balance competition among species. The list of "...supplemental shrub seed used in years 1981-1486" appears to be somewhat inaccurate. Of the twelve (12) species listed in 1981, only one (1) is a shrub species (winterfat). Also, of the eight (8) species listed in 1982, again only one (1) is a shrub species (antelope bitterbrush). For years 1984-1986, the listing does represent shrub species. PCC should modify the introductory paragraph to denote that the listing includes both shrub and forb species. The commitments made by PCC in "Measures to be Implemented" (Pages 29-30) provide a wide range of methods that should assist in increasing and verifying tV,e shrub component at the Seneca II Mine. However, the proposal by PCC "...that certain areas be exempted • from seeding of the primary seed mix in order to provide 36
