Status of woody vegetation along riparian areas in Gonarezhou National Park, Zimbabwe

We assessed the composition and structure of woody vegetation along Save, Runde and Mwenezi rivers in Gonarezhou National Park, Zimbabwe. Data were collected from 62 sample plots between April and May 2011 using a stratified random sampling design. Our results showed significant differences in plant height, shrub density and numbers of stems per plant across the three major perennial rivers. However, there were no significant differences in basal area, tree density, dead plant density, browsed plant density, fire damaged plant density and species diversity. Our findings suggest that disturbances, e.g., herbivory, are affecting the woody vegetation structure in all major rivers in Gonarezhou. We therefore, recommend for the continuous monitoring of riparian vegetation in Gonarezhou and other similar protected areas
