According to the Shannon’s Index, the fenced area has a higher diversity which indicates less competition between species. The lower value of the unfenced area indicates that invasive plants have decreased the ability for other plants to survive in that community. In the fenced community, the Simpson’s Index shows more diversity in comparison to the unfenced community. While the fenced area has greater species richness due to the number a species found it has a lower evenness than the unfenced community. Due to the decreased species richness in the unfenced community there is a higher dominance of species found there. This allows for the dominant species to spread and take over. This can be seen from how the fern takes over much of the understory floor. The Sorenson’s Index reveals some overlapping qualities between the two communities but not enough to consider them identical.

The biodiversity of the given ecosystems may also be influenced by the human influence whereby the disturbance caused by human beings on the ecosystems may adversely affect the native plants while favoring the existence of the invasive species of plants. Since the ecosystem existed in equilibrium where by the number of deer were in proportional to the number of the native plants, the increase in the number of deer results in the decrease in the number of native species of plants while favoring the increase of the number of the invasive species (Knight
