Abundance and Diversity of Small Mammals Found in Forest Habitat Compared with Prairie Habitat

Abstract

Many factors can influence the biodiversity in a particular habitat. In this study, we looked at the biodiversity of small mammals in four forested habitats and four prairie habitats. We predicted that heterogeneous habitats would be more diverse, while disturbed areas would be less diverse. We set up a 5 x 10 trap-grid in each of the eight habitats, using a combination of Sherman, Russian, and Longworth traps. We checked traps in the forest habitats once a day for three consecutive days and traps in the prairie habitats twice a day for three consecutive days. Results indicate that biodiversity of small mammals is greater in most of the forested sites than in prairie sites. We also observed that the red-backed vole and the deer mouse were present in both forest and prairie habitat while other species found were only common in prairie or forest.
