<br />-31- Revised OCT S 0 1981 <br />-~ <br />Vegetation Type #2 - Upland Sa ebrush. The upland sagebn,ch type on the <br />affectsi area ormprised 6.06 acres or 5.78 of the total pexmit area. The <br />type occurs on well-drained soils on areas not disturbed by agricultural <br />practices (MaP entitled "Vegetation Typal", Appetdix A). Eighteen species <br />were encountered in Dover quadrats aid the species diversity index was 2.14. <br />Tbtal. cover (vegetation plus bare ground plus litter-rock) for the upland <br />sagebrush affected area was estimated at 81.68. Of this total, vegetation <br />basal cover accouits3 .for 13.48. Litter-rock and bare grand ca~rised 26.6 <br />and 41.68 of the total Dauer, ~ttvely. The type is characterized by <br />Basin big sagebrush. This species evidencsi 4.48 basal cover, the highest <br />of any spesi.es, while canopy cover estimates were 22.28. Also, big sagebrush <br />-' had the highest frequency value (38.58) of any species whose base was <br />enoountez~ in Dover quadrats. Forbs accamted far 32.88 of tl~ total vege- <br />tation basal Cover. 1t~e sort anteonly-enmtmtered forb (25.68 frequency) <br />and the mavt dominant in terms of rover was~redsten filaree (Erodium cicutar- <br />i~m0. fvssiamlustle, scarlet globemallow, tumblixg hedgErm,cra„9 and sticlc- <br />seed were other catmrn Eorbs.

Ito other shrub species were also present in this type: Four <br />wing saltbush at 180 shrubs/ha and Yubber xabbitbzush at 66.4.shrobs/ha. <br />Shrub.height for big ~"g=~^~=h averaged 36.6 an (14.4 inches). Foes-wing <br />saltbush (Atriplex canesca,s) was also present on the site; the species <br />was approximately twice as high as big sagebrush with an average height of <br />71-.1 an (28.0 inches). <br />Upland sagebrush in the affected area was the most-praluctive vegetation type <br />sartgled on the pennit~area; total production wee 917.3 lbs/acre. Basin big <br />sagebrush accrnmted for 79.08 of the total production 1721.9 lbslacre). The <br />grass and forb stratus contriluted 91.08 acd 6.08, respectively, to total <br />production.
