AbstractDeterioration of arid rangelands around the world is a major concern to the present and future management of these vast land resources. Revegetation efforts are hampered by excessive inputs with low expectations of success. We are implementing natural passive methods such as water, wind, and animals to disperse and establish desirable grass and shrub species on the Jornada Experimental Range in southern New Mexico. In bajada habitats, we have established small seeding blocks and gully seeders along shallow, gentle sloping drainages utilizing portable watering systems. Once desirable grasses and shrubs are established, they will slow water runoff, deposit soil and debris, and produce seed for downstream seeding. In coppice dune habitats, we are establishing fourwing saltbush (Atriplez canescens (Pursh) Nutt.) in seeding blocks for wind and rodent dispersal of seed to determine its competitive ability with mesquite. Additionally, we are determining the potential of using livestock to increase seed of desirable species in specific areas. These low input methods are being incorporated into routine animal and land management practices that are expected to have long-term influences on changing vegetation patterns.
