Pellet Counts The amount of deer duuu on an area may be nsed as an indicator of total deer pressure on range forage. A eount of deer pellet groups on ])lots scattered throughout the Lassen-AVashoe range yielded averages which rellect the nvnnber of deer on the ai-ea each year nndti|)lied by their leugth of stay. These averages may be used dii'eclly as an index of intensity of range use by deer. The averages for the four winters under consideration were as follows : 1!J4'J-.jU 2G1 f^roups per acre 1950-51 276 groups per acre 1951-52 4.38 groups per acre 1952-53 236 groups per acre The highest pressure occurred during the winter of 1951-52, when record snowfalls drove in deer from marginal ranges and confined them on the study area for a protracted period. The lowest pressure occurred during the relatively mild, open winter of 1952-58, when the deer herd, which had been reduced by the die-off of the previous year, remained scattered on the range.
