r~ .. <br />3. Provide for the practical preservation of the natural, esthetic, and <br />recreational qualities. This could include providing view barriers of <br />untreated land along major roads. It may also include the preservation <br />of irregular strips along perennial streams, lakes, marshes, and upland <br />meadows. <br />4. Include the needs of wildlife species in the overall management plan. <br />If on-site evaluation identifies critical problems, the SCS Biologist <br />and Colorado Division of wildlife will be consulted. <br />s. No sagebrush shall be treated or destroyed within one-fourth mile of any <br />known sage grouse "strutting" ground and these "strutting" yrounds <br />should not be isolated within treated areas. Leave a minimum 100-yards- <br />wide strip connecting "strutting" grounds to permanent sagebrush cover. <br />Control of mountain big sagebrush and Wyoming big sagebrush should not <br />be encouraged on areas designated as critical wildlife habitat. <br />a. If an area is to be burned, refer to prescribed burning <br />specifications for crontrol by burning. <br />b. Mechanical Treatment <br />(1) Plowing or Rotary Tiller Equipment <br />(a) Adaptation. Effective on a1Z shrubs such as big sage- <br />brush (alI subspecies), broom snakeweed, tall rabbit- <br />brush, black greasewood, and five-stamen tamarisk on <br />range sites with relatively stone-free soils and level to <br />moderate slopes (generally Zess than 25 percent). <br />(b) Type of Equipment. Moldboard p1 ow, Wheatland plow, heavy <br />offset disk, brushland plow, heavy sweep and roottype <br />plows, and heavy rototiller-type equipment. <br />(c) Time of Operation. Late spring or early summer when soil <br />conditions are favorable for plowing before shrubs have <br />matured seed. (Soils should be dry enough to severly <br />limit regrowth on partially covered plant roots and <br />crowns.) <br />(d) Methods. Plow or rotary-ti21 at a depth sufficient to <br />sever taproots. Operate disk-type plows at a sharp angle <br />to insure completely cutting the roots. (Sometimes this <br />will require a follow-up disking in late August to <br />complete the kill.) <br />(e) Refer to seeding specifications (550) for <br />ce-establishmefit of forage cover. <br />TG Notice 223 <br />-5- <br />Colorado, SCS, Flay 1984 <br />
