Other claims from this paper (7)

Observation Bhadra riparian zones contained 48 tree species from 24 families, dominated by Fabaceae.
Observation Pongemia pinnata was dominant, IVI 35.8.
Observation Leucaena leucocephala was dominant, IVI 30.1.
Observation Eucalyptus was dominant, IVI 18.3.
Observation Terminalia arjuna and Syzygium cumini had very low IVI values.
Association Dominance of non-riparian species suggests anthropogenic pressure on Bhadra buffers.
