Title: Primary production and canopy cover in bitterbrush-cheatgrass communities

Aboveground grass and forb production averaged 126 g m/sup -2/ yr/sup -1/ and ranged between 10 and 195 grams over a four year period 1975-1978. The low production year was 1977, a year of extreme drought. Production was not significantly different between unburned sites and burned sites five years post burning (1970). Canopy cover and species composition were similar on burned and unburned sites except for the shrubs, bitterbrush (Purshia tridentata) and sagebrush (Artemisia tridentata), which were killed by burning. There was no indication that shrubs were invading the burned areas as seedlings or vegetatively through sprouting. The implications of burning and mule deer (Odocoileus hemionus) management are briefly discussed.
