This forest is dedicated to Nagraj Devta and is dominated by tree species, including Quercus floribunda, Quercus semecarpifolia and Rhododendron arboreum. The highest values of below ground bio- mass density, total biomass density and total carbon density were (34.81±1.68) Mg·ha^-1, (168.26±9.04) Mg·ha^-1 and (84.13±4.18) Mg·ha^-1 for Pinus wallichiana. Overall values of total biomass density and total carbon density calculated were 1549.704 Mg·ha^-1 and 774.77 Mg·ha^-1 respectively. Total value of growing stock volume density for all species was 732.56 m3·ha^-1 and ranged from (144.97±11.98) m3·ha^-1 for Pinus wallichiana to (7.78±1.78) m3·ha^-1for Benthamidia capitata.展开更多

The management practice varies and there are forests with high degree of protection, where no extraction(sacred forests) is allowed. There are also forests with moderate-level of protection and-extraction(reserved forests) as well as forests with low level of protection and open extraction(village forests). The present study was conducted to understand the impact of this traditional management system on the level of human disturbance, and on community composition and structure of the forests in Khasi hills of Meghalaya. The result revealed that disturbance index was low, whereas species richness, density and basal cover were significantly high in forests with high degree of protection(sacred forest) than those with low protection(reserved and village forest). Majority of endemic and threatened plant species were restricted to sacred forests as compared to the other forest types. Though these practices have ensured the sustainable use of forest resources by the local people but due to increased human-pressure and-disturbances, more effective conservation strategies need to be undertaken. Therefore, providing alternatives for fuelwood to local people, environmental education, encouraging afforestation and developmental activities involving local communities are recommended.展开更多

We conducted a multifaceted rapid assessment to evaluate the conservation status of the grove eleven years after it was designated a World Heritage Site. We recorded a rich diversity, consisting of 2 rock types, 3 minerals, 88 plant species, 108 insect families and 4 mammal species. Our survey also enabled us document up to 40 cultural artifacts. However, the plants, small mammals and insects collected, in their role as indicator taxa, demonstrate that biodiversity decreases extending outward from the core area of the grove into the buffer and outside zones. In addition, the detection of heterotrophic bacteria and fungi from microbiological analyses in water samples of the Osun River which runs through the grove raises health concerns. Our findings lead us to recommend that efforts be stepped up to deter encroachment of the buffer and outside zones into the core area of the grove. Furthermore, careful repair of deteriorating cultural artifacts should be undertaken regularly, with the actions of visitors monitored adequately to prevent depletion of biodiversity and pollution of the environment.展开更多

Cherrapunji besides being highest rainfall receiving area, is characterized by complete deforestation and soil erosion with sparse grasses forming the surface growth, whereas the sacred forests are conserved in their pristine nature due to religious beliefs of the indigenous tribes. The effect of deforestation and land degradation on soil microbes, soil organic carbon, soil nitrate nitrogen, soil pH, soil temperature, and fungal CFU/g were investigated from the two contrasting sites. The sites showed great variability in physical and chemical parameters including soil composition, temperature, pH, soil carbon, nitrogen content, water availability and enzyme activities. The population count of fungi was higher in sacred forest soil than degraded land of Cherrapunji. In both soil types, Penicillium perpurogenum markedly dominated and the co-dominant species (Aspergillus sp., Fusarium sp. and Trichoderma sp.) were common in both virgin and degraded soils. A total of 63 species were identified during the study period. The species composition between the two sites showed some variation as Syncephalastrum sp., S. chartarum, Gliocladium sp., Eupenicillium osmophilum and Eurotium sp. were not present in Cherrapunji. The undisturbed sacred forest fungal communities had significantly higher Simpson, Shannon and evenness indices than that of degraded soil of Cherrapunji. The prolonged anthropogenic activity in the area leading to degradation coupled with heavy rainfall has decreased the diversity level of fungal communities and masked the pristine differentiating effect of soil on the fungal community.展开更多
