| Description |
We have quantitatively analyzed the tree
species diversity with respect to soil nutrient status in
three sites of a sacred forest ecosystem of Niyamgiri
hill range, Eastern Ghats, India. Extensive field
surveys and sampling were conducted in 3 sites of the
hill range: Site 1 Pterocarpus dominated forest (PTF)
(19°40'02.2" N and 83°21'23.1" E), Site 2 Mangifera
dominated forest (MAF) (19°40'02.8" N and
83°21'40.8" E) and Site 3 Mixed forest (MIF)
(19°36'47.1" N and 83°21'02.7" E). A total of 28
families, 42 genera, 46 tree species, and 286
individual trees were recorded on an area of 0.6 ha.
Tree density varied between 470 and 490 individuals
ha-1 and average basal area between 3.16 and 10.04 m2
ha-1. Shannon Index (H′) ranged from 2.34 to 4.53,
Simpson’s Index ranged from 0.07 to 0.09, and
equitability Index ranged from 0.7 to 1.34. The
number of individuals was highest in the girth at
breast height (GBH) class of 50-70 cm. The soil
nutrient status of the three forest types was related to
tree species diversity. The soil pH value of the three
sites reflected the slightly acidic nature of the area.
Species diversity was positively correlated with
organic carbon and phosphorus and negatively with
nitrogen, EC and pH. The results of the current study
may be helpful to further develop a conservation plan
for tree species in tropical sacred forest ecosystems.
