Detailed Ecological Assessment Report 2008 – Keenjhar Lake
It can be concluded that the index runs (highest firsts) as Keti Bunder >Pai
Forest>Keenjhar lake >Chotiari Reservoir>Keti Shah. It is important to note that
species similarity and species diversity increases from Keti Bunder to Keti Shah
4.4.3.2 Winter surveys
Table 46 and Figure 36 show the biodiversity index for winter results at Keenjhar
Lake.
Table 46 – Biodiversity index for sites surveyed during winter
S.no Site Biodiversity index
1 Keti Bunder 0.02
2 Keenjhar Lake 0.007
3 Pai Forest 0.044
4 Chotiari Reservoir 0.005
5 Keti Shah 0.032

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