Abstract

The present study was conducted in five communities of a sub-tropical swamp forest of Doon Valley, India. The aim of the present paper is to study the various changes in the community structure as a result of change in seasons and soil moisture regime. In moist communities local species were dominant and as the soil moisture (%) lessened their dominance decreased. Importance Value Index (IVI) of all dominant species of the swamp varied significantly during the study period, indicating that they are noticeably affected by the changes in the moisture regime of the swamp. Various indices of association were calculated to find out species association and the results of these indices shows that all the local species were closely associated. Species richness, Shannon- Wiener diversity index (H'), concentration of dominance (Cd) and beta diversity (β) of the five communities were also calculated. Pearson's correlation was used to find out relationship between soil moisture (%) and diversity indices. The results of the correlation analysis reveal that soil moisture (%) was negatively correlated with species richness and H' and positively related with Cd and β diversity.

Abstract

The present study enumerates floristic diversity of the Karwapani swamp forest in Doon valley, Uttarakhand. This study was conducted in the year 2002-2003. The plant diversity of Karwapani swamp forest is represented by 53 families, 130 genera and 155 species of angiosperms. The present study reveals low diversity of angiosperms when compared with Babu and Dakshini probably due to closed canopy of tree species. Dicots contributed approximately 83% of the floral diversity. The tree layer of the forest is dominated by Shorea robusta, which is associated with Mallotus philippensis, Mangifera indica, Syzygium cuminii etc., and the shrub layer is dominated by Ardisia solanacea, Asparagus adscendens, Calamus tennuis, Clerodendrum viscosum and Lantana camara while the herbaceous layer includes, Nasturtium officinale, Ageratum conyzoides, Oplismanus compositus, Pouzolzia pentandra and Mentha piperata.

Abstract

Govind Wildlife Sanctuary and National Park, Uttarakhand is characterized by rich diversity of ethno-botanical plants. The present investigations is an attempt for the documentation of MFPs used by local people of the sanctuary, from the floristic diversity data collected from Sep., 2005 to March, 2007. We used participatory rural appraisal and standard vegetation sampling methods in three sites located at different altitude, to investigate about the ethnobotany of plants. The present study reveals that the 173 plants belonging to different families are used for various purposes by local people. From 137 species reported from the Har-ki-Dun site, 112 species out of them were MFPs whereas in Osla site out of 64 species recorded, 30 species were MFP and in Bencha site within 47 species, 17 were MFP species.The 14MFP species were reported from other locations in the sanctuary.

Abstract

The present paper is a result of exploration of entire Jaunsar-Bawar Chakrata, Dehradun, Uttarakhand. In all 706 plants have been listed. Of these 583 belong to dicotyledons and 123 to the monocotyledons. The dicotyledons are distributed with 107 families and 371 genera. While monocotyledons are distributed with 14 families and 81 genera.

Abstract

The Chakrata Forest Division is in Dehradun district. The locals of Chakrata are tribal and popularly known as 'Jaunsaris'. These people live in the small gathering near the forest and still depend on natural resources for their day to day need. A total of 17 plant species are recorded from the wilderness that are consumed by locals by directly collecting from the forests. Species like Diplezium has become so popular that it is routinely collected from the wild and sold in the nearby market. There are many other species which are used as vegetables, and few are used as spices and condiments. These include herbs, shrubs, trees and ferns. Parts of the plants are used as vegetables include stem, twigs, leaves etc.
