Abstract | During the past year, an area on the Jornada Experimental Range infested with creosotebush and some honey mesquite was rootplowed and seeded with the arid land seeder prototype equipment developed in the 1960's. Lehmann and Boer lovegrasses, black and sideoats grama, yellow bluestem, blue panicgrass and forwing saltbush were used in the seeding. The Jornada Experimental Range is planning to treat about 200 acres with this equipment so the effects of rootplowing and seeding on the ecosystem can be studied. Other vegetative rehabilitation equipment that members of the workgroup are developing are a low-energy grubber, new rangeland seeder, disk chain and land imprinter. |
