Description: The objectives of our study were to determining the effects of velvet mesquite (Prosopis velutina) removal, control of the resulting basal sprouts, and mulching treatments on herbage production (standing biomass) and selected soil chemicals (nutrients) shown to affect herbage production on the Santa Rita Experimental Range. Mesquite control treatments consisted of overstory removal by chain saw with and without control of the resulting basal sprouts. Mulching treatments were applications of mesquite wood chips, commercial compost, or lopped-and-scattered mesquite branchwood. Mesquite removal resulted in increases for total herbage production and the production of native herbaceous species. Production of the nonnative Lehmann lovegrass (Eragrostis lehmanniana), the dominant herbaceous species, was unchanged. The mulching treatments did not affect herbage production. None of the treatments affected soil chemical properties thought to influence herbage production.
