Using a Grid to Estimate Production and Utilization of ShrubsSpringfield, H. W. (Society for Range Management, 1974-01-01)Production of fourwing saltbush plants was estimated from photographs against a 1-inch grid. All squares partially or completely obscured by plant material were counted. Utilization of several shrub species was estimated from photos taken before and after browsing by deer. With modification, the technique could be used for other species and situations.
Winterfat Seeds Viable after 8 Years Refrigerated StorageSpringfield, H. W. (Society for Range Management, 1974-01-01)Five collections of winterfat seeds from New Mexico were stored in cans under refrigeration (34-42 degrees F) and ordinary temperatures (55-95 degrees F). After 8 years of storage, viability ranged from 51 to 80% for the refrigerated seeds, but practically no seeds remained viable under the warmer storage temperatures.
