Detailed Ecological Assessment Report 2008 – Keenjhar Lake<br />
It can be concluded that the index runs (highest firsts) as Keti Bunder >Pai<br />
Forest>Keenjhar lake >Chotiari Reservoir>Keti Shah. It is important to note that<br />
species similarity and species diversity increases from Keti Bunder to Keti Shah<br />
4.4.3.2 Winter surveys<br />
Table 50 and Figure 36 show the biodiversity index for winter results at Keenjhar<br />
Lake.<br />

It is evident from the lower values of biodiversity index in the above table and<br />
graph that the avifauna is not diverse. However, the sites can be arranged on a<br />
scale of species diversity in descending order as:<br />
Pai Forest > Keti Shah > Keti Bunder> Keenjhar lake > Chotiari Reservoir<br />
Again Pai Forest has the highest index followed by Keti Shah and then Keti<br />
Bunder. This is quite unusual since all of these sites are subjected to<br />
environmental degradation, especially Pai Forest. It would have been expected<br />
that the three wetlands, Chotiari Reservoir, Keti Bunder and Keenjhar Lake would<br />
have been on top, especially for avifauna.<br />
Coming to the similarity index, the following list and Figure X gives the similarity<br />
values across all sites<br />
