Abstract

Responses of stream chemistry parameters, nitrate-N (NO3-N), phosphate (PO4), calcium (Ca), magnesium (Mg), potassium (K), sodium (Na), and hydrogen ion activity (pH) were measured on 13 wildland watersheds managed at four different grazing strategies. Range management strategies tested were (A) no grazing, (B) grazing without control of livestock distribution (8.2 ha/AUM), (C) grazing with control of livestock distribution (7.7 ha/AUM), and (D) grazing with control of livestock distribution and cultural treatments to improve forage production (2.8 ha/AUM). Nitrate-N, PO4, Ca, Mg, K, and Na were significantly (p
