Keti Bunder
Keenjhar Lake
Chotiari
Reservoir
Pai Forest
It can be inferred the biodiversity runs (highest first) from Keti Bunder >Pai Forest
>Keenjhar Lake> Chotiari Reservoir>Shah Belo.
Interestingly Chotiari Reservoir comes second to last whereas it would be
expected to be on top like it does for mammals, reptiles and amphibians. Keti
Bunder and Keenjhar Lake certainly have the potential to support a diverse
variety of avifauna even though they are subjected to a high level of
environmental degradation.
Looking at similarity index it can be inferred that the index value (highest first)
runs as: Keenjhar lake: Chotiari Reservoir = Keenjhar Lake: Keti Shah>Chotiari
Reservoir: Shah Belo>Keti Bunder: Chotiari Reservoir=Keti Bunder: Keenjhar
lake>Pai Forest: Chotiari Reservoir>Keti Bunder: Keti Shah>Keti Bunder: Pai
Forest>Keenjhar Lake: Pai Forest
Note: Species Similarity decreases from Keenjhar Lake: Chotiari Reservoir =
Keenjhar lake: Shah Belo to Keenjhar Lake: Pai Forest
The list below gives the comparison index for each comparison. Figure 34 gives
a graphical outlay of the index.
