“…Without the basic understanding about the structure of a community, it is impossible to know its functioning. Thus a lot of phytosociological studies have been conducted throughout the world to understand the structure of different forest communities (Campbell et al, 1986;Timilsina et al, 2007;Top et al, 2009;Sambare et al, 2011;Erenso et al, 2014). In Indian scenario, several phytosociological studies have also been performed in different tropical forests: Western India (Sharma and Upadhyaya, 2002;Panchal and Pandey, 2004;Krishna et al, 2014), Peninsular India (Parthasarathy et al, 1992;Visalakshi, 1995;Parthasarathy, 1999;Mani and Parthasarathy, 2005;Gunaga et al, 2013), North East India (Bhuyan et al, 2003;Kumar et al, 2006;Kibria and Saha, 2011;Sarkar and Devi, 2014) and Northern India (Singh and Singh, 1991;Sagar et al, 2003;Pandey and Shukla, 2003;Chauhan et al, 2008;Tripathi and Singh, 2009;Behera et al, 2012).…”

A phytosociological assessment was done in Terai-Bhabar region of the central Himalaya to understand the current status of a monotypic genus Indopiptadenia. Identification of different forest communities within the region was also accomplished. Cluster analysis and PCA revealed five forest communities (i.e., sal miscellaneous forest, sal dominant forest, lowland miscellaneous forest, teak plantation and Indopiptadenia population) on the basis of their species composition. Out of these 5 communities, Indopiptadenia population attracted more attention due to its small and declining population. The unique habitat of this small population found chiefly on gravely-sandy soil along the water streams edges places it before the natural threats of floods and cutting of river banks. The lowest tree density (440.00 stem haG values were exhibited by this plant community. This suggests that the population of Indopiptadenia is more exposed forest community in comparison to others and faces higher degree of anthropogenic pressures for their fodder and timber values.

“…Variations in these attributes are observed due to climate, topography, soil and anthropogenic factors. These factors along with forest succession causes local and landscape level variations in forest attributes and produce spatial heterogeneity (Timilsina et al 2007).…”

With the growing global concern about climate change, relationship between carbon stock density and tree species has become important for international climate change mitigation programmes. In this study, 150 Quadrats were laid down to assess the diversity, biomass and carbon stocks in each of the forest ranges (Barkot Range, Lachchiwala Range and Thano Range) of Dehra Dun Forest Division in Doon Valley, Western Himalaya, India. Community level carbon stock density was analyzed using Two Way Indicator Species Analysis. Species Richness and Shannon Weiner index was correlated with the carbon stocks of Doon Valley. Positive and weak relationship was found between the carbon stock density and Shannon Weiner Index, and between carbon stock density and Species Richness.

“…The diversity (H) was determined by using Shannon-Weiner information index [51] as H= -∑ni/n log2 ni/n; where ni was the SIV value of a species and n was the sum total SIV values of all species in that forest type. Simpson's diversity index [52] was calculated as Ds = 1-Cd, Where Cd = Simpson's concentration of dominance = (∑ni/n) 2 . Indices used to calculate 'r' species evenness included Peilou's Index [53] as E 1 = H/ln (s) and Sheldon's Index [54] E 2 = eH/s, where H is Shannon-Wiener's Index and 's' is the number of species.…”

The study was conducted on sub-tropical forest of districts Jammu and Samba of Jammu province of Jammu and Kashmir state, India with the objective of determining floristic composition, species diversity and structure of woody vegetation in drier Kandi Siwaliks. The forests of Kandi belt represent typical subtropical vegetation with distinct vertical zonation of three forest types i.e., Northern dry mixed deciduous forests (5B/C2), Himalayan subtropical scrub (9/C1/DSI) and Himalayan subtropical Pine forest (9/C1a) in an altitudinal range of 300 m asl to 990 m asl. The community analysis was performed using stratified random sampling involving 0.01 % of the total area for each community. Accordingly, 750 quadrats of 400 m 2 and 100 m 2 were laid for trees and shrubs respectively after attaining their species area curve. Various phytosociological parameters and diversity indices have been used to reveal the community structure, species richness, diversity and evenness for the phanerophytes in different forest types. A total of 112 species comprising 65 trees and 47 shrubs belonging to 92 genera and 48 families were recorded from the forest. The vegetation analysis revealed the dominance of Mallotus philippensis (SIV %, 6.4), Acacia modesta (10.44 %) and Pinus roxburghii (24.27%) as over storey elements in northern dry mixed deciduous forests, Himalayan subtropical scrub and Himalayan subtropical Pine forest respectively. The northern dry mixed deciduous forests occupying 27.3 % of the study area revealed maximum species richness and diversity as indicated by the higher values obtained for Shannon-Wienner's index and Simpson's index of dominance. Most of the forest landscapes are influenced by human disturbances and thus necessitates the need for immediate conservation action plan to ensure sustainable utilization and better management of forest.
