Detailed Ecological Assessment Report 2008 – Keenjhar Lake Relative abundance was calculated and categorized into five divisions (Rare, Less Common, Common and Very Common). At country level Common species were the most abundant category (42 species, 76.4%) followed by Less Common (11 species, 20%) with very few representation from Rare or Very Common categories. Abundance at local (relative) level was dominated by Less common (23 species, 41.8%) followed by Common (16 species, 29%) and then Rare (13 species, 23.6%). Very common was only represented by two species (3.6%). Figure 13 gives an account of both local and country status.
