Evaluation of plant community use and preference by pigs must be considered in light of bias in observations of pigs; survey effort was not distributed equally among plant communities, and pigs were not equally visible in different com- munities. Chaparral was the community sampled most intensively in proportion to its availability, but it was also the community in which pigs were least visible, tending to cancel some of the bias. Moreover, bias in survey effort was relatively consistent from month to month, and hence comparisons among months proba- bly reflected trends in actual pig distribution. Most pigs observed in October and November were in chaparral, grassland, or oak woodland (Table 1). In December and January, occurrence in chaparral and oak woodland declined, while occurrence in grassland increased. Beginning in February and March, and continuing through April and May, few pigs were observed in chaparral as they apparently shifted to more open habitats, appear- ing most often in chaparral-grassland and grassland.
