Springfield, H. W.
Seed characteristics of winterfat are being investigated because this shrub species has value in revegetation. Seeds collected 4 consecutive years in New Mexico were tested for viability at 1- to 4-week intervals after collection. After-ripening was completed within 10 weeks for all except one collection, which required 25 weeks. Variation in the after-ripening process among years probably resulted from differences in environmental conditions during seed formation. Seed technologists and others working with winterfat need to be aware of the after-ripening requirement.

Frischknecht, N. C.; Baker, M. F.
During cyclic population peaks, voles kill and damage sagebrush and other shrub species over large areas. Damage is greatest when a dense, ungrazed herbaceous understory exists and when the snowpack persists throughout the winter. If peaks in population could be predicted, grazing should be managed to leave all possible herbaceous cover on areas where killing of brush is desired; conversely, grazing by cattle should be heavy where perpetuation of shrubs is preferred.

Arnold, P. K.
Remote sensing from satellite systems offers real potentials for data collection on rangeland problems, structure, and use. When techniques, now being tested at a number of locations, have been more fully developed, more information from remotely based sensors will be available for reducing the uncertainties surrounding daily policy and management decisions. Techniques under development are discussed.
