Recovery of a Bearclover ('Chamaebatia foliolosa') Plant Community after Site211 Preparation and Planting of Ponderosa Pine Seedlings

摘要

Bearclover inhabits thousands of acres of forest land in northern and central211u001eCalifornia, but little quantification of its recovery after timber harvest, site 211u001epreparation, and planting is available, and the species composition and 211u001edevelopment of the ensuing plant community is largely unknown. Density, foliar 211u001ecover, and height of planted ponderosa pine seedlings, bearclover, whiteleaf 211u001emanzanita, forbs, and grasses were documented from 1986-1996 in northern 211u001eCalifornia. After 11 growing seasons, bearclover and planted ponderosa pines were 211u001edominating, whiteleaf manzanita was increasing, grasses were still numerous, and 211u001ethe forbs had come and gone. A total of 12 plant species were found during the 211u001estudy period. Elongation of bearclover rhizomes took place for 2 years after site 211u001epreparation and then abruptly ceased.
