Jaldapara Wildlife Sanctuary has been surveyed for the availability of type and amount of Non-Timber Forest Produces. A total of 132 species has been recognised as NTFP producers which include plants of different habit groups, occupying different strata and types of vegetation. While the existence of an established market for only 22 of these articles are there a list of another 27 articles have been provided for which proper markets need to be developed immediately. Prices for at least 33 articles could not be ascertained. Stress has provided for the proper survey of NTFPs in North Bengal vegetations and to develop strategies for their proper sustainable extraction and utilisation.- Wasteland Reclamation by some Papilionaceous Taxa - Possibilities and Prospects

Assuming the importance of Papilionaceous plants in improving the habitat conditions in the highly degraded vegetations attempt has been made to record such plants growing naturally ill semiarid and chiefly red-lateritic soils of Sambalpur District of Orissa. As much as 62 such species has been recored growing naturally in this tract. The phenology of the plants along with its nodulation has also been collected. Introduction of these plants in the plantation of tree species will improve the habitat conditions gradually and thus the valuable germplasm of the important taxa will be conserved.- Phytosociological Studies of the Ground Flora in Different Types of Vegetation on Tiger Hill, Darjeeling District, West Bengal

A large part of Tiger Hill forest (Darjeeling, West Bengal) was clearfelled in the first decade of this century and a part of it was planted with Cryptomeria japonica (L.f.) D. Don in 1921. Now there exists three types of vegetation side by side: (i) Natural Forest, (ii) Plantation Forest and (iii) Grassland. Phytosociological studies were made to understand the differences in the ground covering vegetation within these vegetational types and to understand tbe Relative Density, Relative Frequency and Importance Value of its elements. Altogether 85 species and 3,672 individuals were recorded from just 15 one-square meter quadrats. While 33.33% species were same between Natural Forest and Plantation Forest, it is only 7.25% between Natural Forest and Grassland and 13.84% between Plantation Forest and Grassland. Theropbytes (40%) appeared to be a most successful lifeform, but Chamaephytes (24.7%) were also well represented along witb 14.12% Cryptophytes, 12.94% Hemicryptophytes and 8.23% Phanerophytes. Most of the 31 species of angiosperm recorded from the Plantation Forest were sparsely distributed, feeble and produced only few or no flowers. A more spaced plantation of Cryptomeria japonica mixed with selected broad-leaved non-resinous trees has heen suggested here to improve the picture. However, all species recorded from Natural Forest (37 spp.) and Grassland (43 spp.) were normal in their development and reproduction though were much affected with grazing.- Angiospermic Flora of Bethuadahari Reserve Forest, Nadia (india)
