Bird diversity<br />

Mean species richness, equities and diversities in<br />

dry deciduous miscellaneous forest, moist deciduous<br />

miscellaneous forest, evergreen forest, sal forest,<br />

scrub forest, riverine habitat, plantations and<br />

encroached agriculture fallow habitat are given in<br />

Table 22. The most important groups in terms of<br />

species richness were Charadridae, Columbidae,<br />

Capitonidae, Picidae, Muscicapidae, Nectarinidae<br />

and Ploceidae. The species effort curves (appendix<br />

28) revealed that the present species detection efforts<br />

are inadequate and more such efforts are required in<br />

each habitat as most of the curves are tending<br />

upwards. Kruskal-Wallis test revealed that species<br />

richness (x 2 7 = 10.91, p = 0.14), equities (x 2 7 = 7.19,<br />

p = 0.41) and diversities (x 2 7 = 10.37, p = 0.17) did<br />

not show statistically significant variations in dry<br />

deciduous miscellaneous forest, moist deciduous<br />

miscellaneous forest, evergreen forest, sal forest,<br />

scrub forest, riverine habitat, plantation and<br />

encroached agriculture fallow habitat. A perusal of<br />

table 24 revealed that species richness and diversity<br />

were higher in encroached agriculture fallow<br />

habitats as compared to others. This could have been<br />

a result of low sample sizes in agriculture fallows<br />

and plantations. However, more equitable<br />

distribution of species was observed in scrub forest,<br />

evergreen forest and riverine habitats as compared<br />

to dry deciduous miscellaneous forest, moist<br />

deciduous miscellaneous forest, sal forest and<br />

plantation.<br />

Distribution of flagship species<br />

Although very few threatened species were seen<br />

during this survey and the distribution was largely<br />
