Cronin, E. H.
Herbicide treatments that effectively control tall larkspur also convert the tall-forb community to a grass-dominated community. The composition of the grass community is determined more by the grazing system imposed on the treated area than by the herbicide treatments. Early grazing reduces mountain brome and increases letterman needlegrass. With protection from grazing, the converted grass community can produce abundant high-quality forage and watershed cover superior to that of the former larkspur-dominated tall-forb community.

Papanastasis, V.
The effect of amount of mulch, nitrogen fertilizer, and clipping frequency was studied on herbage and seed production of annual ryegrass (Lolium multiflorum Lam.) seeded on a burned brushland in California. The experiment was continued for 2 years but, in the second year, actual grazing by meadow mice (Microtus californicus) was substituted for the clipping treatment. Available nitrogen in the soil was found deficient in both years but the deficiency was more pronounced in the relatively dry year. Meadow mice reduced herbage and seed yields significantly in the second year. It is concluded that the decline of annual ryegrass in burned brushlands is associated with a corresponding decline through immobilization of available soil nitrogen released by brush burning.

Old World bluestem and Selection 75 Kleingrass established stands more rapidly and produced more topgrowth the year of seeding than did Bell Rhodesgrass or green sprangletop at three locations in South Texas. Based on crude protein content of foliage at maturity, the grasses ranked Selection 75 Kleingrass > Bell Rhodesgrass, green sprangletop > Old World bluestem. Old World bluestem foliage contained only slightly more than 6% crude protein at maturity. However, crude protein content of Old World bluestem, Bell Rhodesgrass, and green sprangletop decreased only slightly from maturity to dormancy. Selection 75 Kleingrass crude protein levels in foliage dropped from about 13% at maturity to less than 9% during dormancy.
