The present study was carried out in four community based religious conserved forests areas i.e., Ansuiya Devi, Ulkagari, Maroor and Jameshwar in Garhwal Himalaya. The aim of the study was to access the ecological and diversity status. The selected sites have status either of reserve forest, communal forest/Van Panchyat or a combination of these apart from having several temples of religious significance. Study was conducted following the stratified random sampling technique by placing random quadrats of 10 m × 10 m size at forest floor. A total of 240 species of plants were recorded from the four study sites, which varied from 93 in Jameshwar to 119 in Ansuiya Devi. The density of these forests ranged from lowest of 782 trees/ha in Jameshwar to 1352 trees/ha in Maroor. The total basal cover (TBC) for trees showed a range of 31.67 m 2 /ha in Ulkagari to 84.34 m 2 /ha in Ansuiya Devi. Distribution pattern of whole herb and shrub layers were found contagious whereas only three tree species were found randomly distributed. Shannon diversity index (Hʹ) for tree species was recorded highest in Ansuiya Devi (2.93) whereas; lowest value (2.10) was recorded in Maroor. Species richness (Margalef index) for trees ranged from 3.29 to 4.35. The study is a pioneer in the aspect and can be helpful in making protocols and policy implications to protect these sites by involving local communities in biodiversity conservation outside the protected area network.

“…Decrease in stem density has been attributed to disturbance intensity (Ramirez-Marcial et al 2001) in Mexico, tree cutting for domestic use in Indonesia (Smiet 1992), and selective and commercial extraction of timber (Elouard et al 1997;Pomeroy et al 2003) in Western Ghats. Several studies have reported more intensive exploitation of forests close to human settlements than those located in remote areas (Acharya 1999;Sagar et al 2003;Ramacharitra 2006). Bhat et al (2011) also observed stem density decreased by (45.5%) in different study sites over a period 25 years in Uttara Kannada district, Western Ghats, south India.…”

Forest tree diversity inventory and its periodical monitoring are important to understand changes in tree population structure and to provide information useful for biodiversity conservation and reserve management. In a long-term forest dynamics program in Indian tropical dry evergreen forest, this communication deals with tree diversity changes at decadal interval. The initial inventory of tree diversity was carried out in 2003, in four tropical dry evergreen forest sites -(much disturbed sites Shanmuganathapuram -SP and Araiyapatti -AP and moderately disturbed sites -Karisakkadu -KR and Maramadakki -MM) on the Coromandel Coast of peninsular India, by establishing four 1ha permanent plots, one in each site. In 2013, the four plots were re-inventoried for tree diversity (≥10 cm gbh) changes which yielded 56 species from 46 genera and 26 families. The studied forest sites are threatened by disturbance due to multiple reasons; cutting of trees inside of the forest, grazing by goats, construction of temple approach road, and some aspects cultural attachment of local people like constructing new, additional strctures of temple by denuding a portion of forest etc.. Tree species richness over a decade increased by four species in site SP, two species in site AP, and one species in site KR, but decreased by one species in site MM. Tree density decreased drastically by 480 (28.92%) and 102 (12.63%) stems ha -1 respectively in sites SP and AP, but moderately increased by 82 (12.09%) stems ha -1 in site KR and 26 in ten years. The long-term forest monitoring data will be valuable to understand forest dynamics and for conservation and management of this and similar tropical forests.

“…The tree species viz., Prosopis juliflora, Albizia amara and Ziziphus jujuba showed highe IVI values, it is due to dry climatic conditions and relatively a disturbed ecosystem. The species compositions of all regional levels directly or indirectly related to the variation of environmental factors [24] and disturbances [25].…”

ABSTRACT. The present study deals with the quantitative floristic inventory of Peddagattu and Sherepally area, Nalgonda district, Telangana State, India. The study resulted in documentation of 50 tree species belongs to 41 genera and 35 families. The families, Mimosaceae, Caesalpiniaceae and Fabaceae are dominated. Among the tree species Cassia fistula has showed highest IVI in Peddagattu, while in Sherepally Albizia amara has recorded highest IVI. Shannon-Wiener index (H') ranges from 2.41 to 3.03. The present study can serve as baseline information for phytosociolgical studies on tree species of Peddagattu and Sherepally area, a proposed site for Uranium mining project, Nalgonda district, Telangan State, India.
