Recovery of chaparral after wildfires was studied at five sites along an elevational gradient from 300 to 1550 m. In January, two months after fire, shrubs at all sites had begun resprouting but no shrub seedlings were present. Shrub resprouts were more abundant at the higher elevations although by June average shrub size was smaller at the higher than at the lower elevations. Initial shrub seedling densities were much higher than often reported for southern California chaparral and was probably due to sampling early in the growing season. Estimates of seedling mortality from March to June ranged from 68% and was dependent on the species. Herbaceous vegetation was most extensively develope at the lowest elevation site. At some sites, herbaceous petennials were a major part of the cover and these species typically established early in the season, largely from resprouts. Annuals were abundant at all but the highest elevation site and non-native annaul species dominated the flora at the lowest elevation site. |
