Figure 1.
Comparisons of vegetation variables describing control and fuel-reduction plots along the Middle Rio Grande, New Mexico, measured from 2000 to 2007. Values are the number of individuals per circular plot of adjusted to number of individuals per hectare. Bars represent means and 95% confidence intervals. For each species of woody vegetation, differing letters indicate significant (P < 0.05) differences between treatment types. Treatment types: CHH, removal of exotic shrubs and woody debris followed by two applications of herbicide; CHPH, removal of exotic shrubs and woody debris followed by herbicide, then planting of native shrubs; PHFH, removal of exotic shrubs and woody debris followed by herbicide and fire. Values have been changed from the number of individuals per plot to the number of individuals per hectare.
