Ms. Sandy Emrich <br />Page 2 <br />August 20, 1984 <br />In summary: <br />Delete pubescent wheatgrass (Aqropyron tricho horum) at I.0 PLS Ib./ac. <br />Add big bluegrass (Poa am la) at 0.5 PLS Ib. ac. <br />Lower common timothy Phleum raTense) to 0.1 PLS Ib./ac. <br />Lower Canada bluegrass Poa co~ressa to 0.1 PLS Ib./ac. <br />Lower alfalfa (Medicago sativa to 0.5 PLS Ib./ac. <br />Increase green needlegrass St, ipa viridula) to 2.0 PLS lbs./ac. <br /> The modified seed mix and rates are listed below: <br /> Drilled Rate* <br /> S ecies Ibs PLS ac Seed/ft2 <br />I.

Additionally, Canada wildrye (Elymus <br />canadensis) and creeping wildrye (Elymus triticoides) are being removed from the Seed <br />Mix No. 2 list. While these species would be desirable and beneficial in the reclaimed <br />plant communities, the lack of available seed for these Two species realistically requires <br />that they be removed from the list. The following two species are to be substituted: <br />basin wildrye (EI mus cinereus) at I PLS tb. per acre and big bluegrass at 0.5 PLS Ib. per <br />acre. Both of these species ar natives and occur in the sagebrush grasslands in The area <br />around Seneca. <br />
