Furthermore, this substitution should not otter on more'than approximately 2S% of the acreage targeting the grazirgland land use, and it would be most beneficial to be placed in or near draw bottoms. If at some future point it is desirable to substitute for a species other an ElcL or on more than 25% of the grazingland acreage, permission will first be gained from CDRMS.
