Long-term recovery of Wyoming big sagebrush after four treatments

Article Abstract:

The recovery pattern of Wyoming big sagebrush is examined by comparing plots that were treated four different ways to determine an effective control of the plant growth. The recovery of the plant is rapid after a plowing and seeding grass treatment. Recovery is slower after burning. Plowing, spraying, and rotocutting treatments result in more sagebrush cover in the long-run. The prohibition of grazing for 30 years did not affect the sagebrush cover in untreated plots. Recovery patterns exhibit successional trends, a cognizance of which is useful for long term control of the bush.
