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.
Keywords: Herbivory, perennial rivers, savanna, species diversity, woody vegetation.
