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 <strong>note</strong> that<br />

species similarity and species diversity increases from Keti Bunder to Keti Shah<br />

4.4.3.2 Winter surveys<br />

Table 46 and Figure 36 show the biodiversity index for winter results at Keenjhar<br />

Lake.<br />

5 Keti Shah 0.032<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 />
