The present study was carried out in Behali Reserve Forest, a semi-evergreen forest of Assam, India to record and analyze the woody species diversity and community characteristics using random sampling. Altogether, 35 quadrats (20 m × 20 m) were randomly established and studied from August 2018 to April 2019 spreading across nine study sites. A total of 128 (118 identified and 10 unidentified) woody species from 83 genera and 43 families were found in the sampled area of 1.4 ha. Lauraceae with 19 species was the richest family by species followed by Euphorbiaceae and Phyllanthaceae (eight species each). Altogether, 787 individuals were recorded from the sampled plots and the stand density ranged between 250 individuals × ha-1 to 725 individuals × ha-1 with mean stand density of 543 individuals × ha-1. Species-wise density analysis revealed that Magnolia hodgsonii (96.43 individuals × ha-1) has the maximum tree density. Plot wise analysis showed that Dikal (58.32 m 2 × ha-1) recorded the maximum basal area as well as the equitability index of 0.95. In Serelia, we recorded the highest Simpson index (0.92), Shannon H index (2.76), Brillouin index (2.11), Menhinick (3.49), Margalef (5.29) and Fisher alpha index (26.59). In Radhasu, we recorded maximum evenness (0.90), dominance (0.58) and Berger-Parker index (0.65). The maximal values of Chao index (38.53) was recorded in Hatimara. Our study also revealed that diversity was maximal for the community under medium level of disturbance in the reserve, while communities under the lowest and highest disturbance pressure had minimal diversity. The Behali Reserve Forest exhibited a great species richness (118 species), mean basal area (44.42 m 2 × ha-1) and stand density (in total, 788 individuals per study area of 1.4 ha) compared to the other forests of the northeastern region of India.

“…Phrynium capitatum, Thysanolaena maxima and Gynocardia odorata. The domestication and cultivation of NTFPs is carried out so that people can produce them in larger quantities and also to protect these species from over exploitation in their natural habitat (Tynsong and Tiwari, 2010). The study shows that the War Khasi community has often been very creative in devising traditional techniques in which production of economically important NTFPs are actively promoted.…”

Ever since their emergence on this planet, human beings have depended on forest resources for much(??) of their requirements, ranging from food, fuel to shelter. Sustainable extraction of forest resources has been promoted by conservationists and development agencies as a feasible strategy for forest dwellers that does not diminish the resource base. Yet surveys of actual resource use suggest that for poorer resource-dependent communities without access to markets, non-timber forest products (NTFPs) can only act as a safety net and a supplementary income source. In southern Meghalaya, India, NTFPs and medicinal and aromatic plants (MAPs) have become an important source of cash and subsistence income for poor people living in or near forests. People in this region have traditionally been collecting different forest products from private forests as well as community conserved forests. The study reveals that NTFPs contribute significantly towards the annual cash income of the local population. The contribution of NTFPs to their income was highest in the case of poor families (9.89%), followed by middle income families (3.34%) and the least for the higher income families (1.34%). Our household survey revealed that 100% of the population is directly or indirectly dependent on NTFPs. Household response indicates diversity in both the types and uses of products collected.

“…The region is rich in biodiversity with majority of endemic species are facing high degree of threats. Further, the region is characterized by high variation in altitudes, soil types, and ecological conditions along with diverse life forms which provide necessary conditions for the region to serve as storehouse of varieties of plant and animal species (Tynsong and Tiwari 2010;. According to World Wildlife Foundation, the entire Eastern Himalayas, which consists of entire eight states of Northeast India and the neighboring countries like Bhutan, Southern China, and Myanmar, have been listed among 200 Global Ecoregion .…”

Abstract. Ao A, Changkija S, Tripathi SK. 2020. Species diversity, population structure, and regeneration status of trees in Fakim Wildlife Sanctuary, Nagaland, Northeast India. Biodiversitas 21: 2777-2785. The plant species composition and diversity represent the overall health of the forest ecosystems and provide useful insight on forest conservation, and the species regeneration is important in assessing the potential of the forests to serve the society on sustained basis. This present study aimed to assess the species diversity, population structure, and regeneration status of the trees in temperate forest of Fakim Wildlife Sanctuary, Nagaland, Northeast India. Tree species composition, population structure and regeneration status were analyzed by randomly establishing eight plots of 0.1 ha within the sanctuary. Density, basal area, abundance, evenness, and other diversity indices were calculated for mature trees with girth at breast height (GBH) ≥ 30 cm. A total of 60 tree species belonging to 40 genera and 27 families were recorded. The most dominant families recorded were Lauraceae and Rosaceae. The total tree density recorded from the forest was 432.5 individuals ha-1 with a basal area 42.8 m2 ha-1. Cinnamomum zeylanicum and Lithocarpus pachyphyllus had the highest density with 17.58 individuals ha-1 and Lithocarpus pachyphyllus had the highest basal area with 2.64 m2 ha-1. The species with the highest IVI was Betula alnoides (17.13). Girth class of 30-60 cm had the highest density and basal area with 280 individuals ha-1 and 20.7 m2 ha-1. The diversity indices such as Shannon-Wiener index, Simpson index, Pielou evenness index, and Margalef species richness index were 3.90, 0.93, 0.92, and 11.59, respectively in the wildlife sanctuary. The present study showed that 41% of tree species exhibited good regeneration status, 31% as fair regeneration, 8% as poor regeneration and 20% had no regeneration. The present data will be useful to understand the current status of tree species and will serve as baseline information to the forest department, policymakers and conservationists to develop management plans for the conservation of priority species in the area.
