Description

Our project investigates the effects of herbivory that prairie and meadow voles, Microtus pennsylvanicus and Microtus ochrogaster, have on the composition of vegetation in a restored tallgrass prairie and savanna. We utilized data from twelve 2 by 2 plots established in 2003, 6 of which were dedicated vole exclusion plots. We mainly observed the abundance and heights of grass and forbs and their interaction based on the vole’s diets. We predicted that grasses in access plots are more likely to be overabundant and forbs in exclusion plots are more likely to exceed the abundance and height of grasses.
