Treatment regimes consisted of manual release (grubbing) over 3 to 6 years and resulted in vegetation recovery times of 4 to 10 years. Revegetation was remarkably diverse, rapid, and vigorous. At the end of the study, the dominant shrub, deerbrush, had significantly lower average density and foliar cover relative to the control when treated either the first 3 years or the second 3 years, but average height was similar regardless of treatment. Average density of the 11 other shrubs was statistically higher in the control relative to other treatments, but cover and height did not differ. Density, foliar cover, and height of the forbs and graminoids did not differ among treatments at the end of the study. In the control, deerbrush plants numbered 6,100 per acre; other shrubs, 2,550 per acre; forbs, 27,300 per acre; and graminoids, 5,800 plants per acre in 1997. Foliar cover of deerbrush at 22,700 ft² per acre was more than five times that of all other naturally established species combined and slightly exceeded that of pine seedlings in all treatments. 606 $aPonderosa pine$zCalifornia$zPlumas National Forest$xSeedlings 606 $aPonderosa pine$zCalifornia$zPlumas National Forest$xGrowth 606 $aPlant succession$zCalifornia$zPlumas National Forest 606 $aRevegetation$zCalifornia$zPlumas National Forest 615 0$aPonderosa pine$xSeedlings. 615 0$aPonderosa pine$xGrowth. 615 0$aPlant succession 615 0$aRevegetation 700 $aMcDonald$b Philip Mark$01387104 701 $aFiddler$b Gary O$01387105 712 02$aPacific Southwest Research Station. 801 0$bORE 801 1$bORE 801 2$bGPO 906 $aBOOK 912 $a9910696539403321 996 $aDevelopment of vegetation in a young ponderosa pine plantation$93436598 997 $aUNINA
