The present study analyzes the diversity and usage of NTFPs and evaluates their importance in the day to day life of the people of rural Meghalaya. People use 172 NTFPs belonging to 139 plant species mainly for food, medicine and fuelwood and to a lesser extent for construction, handicrafts and ornamental purpose. These 139 plants belonged to 117 genera and 70 families with Rosaceae, Poaceae and Fagaceae families as the dominant NTFP yielding families. Fruits from shrubs and trees are most commonly harvested by people. Collection and availability of NTFPs for use as food are more during the summer season, which is also the period with least availability of job. NTFPs for subsistence use are greater in number than those having commercial value. The most commonly harvested plant parts are fruits and leaves. Roots, rhizomes and whole plants are extracted in lesser quantity which is a positive approach from sustainability point of view. NTFPs and other forest products also form a vital part of the rural household's income generation activities.
Firewood serves as the principal source of energy for cooking and heating, for many rural communities, but the impact of firewood extraction on the forest is often undermined. The present study was undertaken to assess the firewood consumption pattern by households living near community forests of East Khasi Hills District, Meghalaya and the impact of such activity on species diversity and population structure on such forests. Data on firewood consumption and preferred firewood species, and impacts of firewood harvesting on species diversity and population structure were collected through household surveys and phytosociological studies respectively. The surveyed households showed high dependency on firewood and the consumption pattern varies with the family size. The preferred firewood species are those of hardwood trees such as Quercus spp., Lithocarpus spp., Castanopsis spp. and Myrica spp. Firewood extraction have negative impact on forests, resulting in decrease in species diversity and population of the preferred firewood species. Statistical analysis revealed that species richness and diversity and density differ significantly in protected and unprotected forests. Despite low per capita consumption of firewood and precautionary measures like regulated harvesting in the study area, firewood harvesting cannot be ignored as an important cause of forest degradation and biodiversity loss. More research into local ecological and cultural contexts and perceptions concerning costs and benefits can help devise sustainable management options, including alternative sources of fuel.
This paper describes a stream biomonitoring program that builds capacity in undergraduate college students in the field of freshwater ecology and conservation. The program involves sampling of aquatic macroinvertebrates and hydrological parameters in streams of the state of Meghalaya, India. Several colleges from Shillong initiated short-term, one-year and long-term biomonitoring of streams in East Khasi Hills and Ri-Bhoi districts. Nine stream locations sampled over October-December in 2014 provided a snapshot of physical and biotic conditions, thus enabling the examination of spatial trends in water quality parameters and aquatic biota. A year-long sampling study from 2014-2015 provided a seasonal view of stream parameters at Lwai (clean) and Umkaliar (moderately polluted) streams. Results from both sampling sets suggest that turbidity negatively affected the richness of pollution sensitive taxa. Dissolved Oxygen values were lower in polluted streams and were non-significantly lower in summer than in winter. After an initial training in the field, the sampling was conducted by college students under supervision from their lecturers. Data obtained on macroinvertebrates adds to the sparse information available on stream ecosystems in the biodiversity-rich northeast Indian region. We hope the paper provides a template for monitoring of vital ecosystems in this and similar regions.
