Community structure and population status of Drosera burmanii Vahl

Quantitative data of community structure and the current status of ecologically and economically important Drosera burmanii Vahl. Populations were gathered at Tripura, India, from two different stands, Suryamaninagar (Site i) and Ishanchandranagar (Site ii). The area of occupancy of Drosera in both sites was measured. A total of 31 species (26 genera of 18 families) were recorded to be associated with Drosera. Species richness index, dominance index, diversity index and evenness index from both sites were analyzed. The relative importance value (RIV) was calculated for all the species found in the study sites and was highest for Drosera. Individuals of Drosera were also categorized into mature, juvenile and seedlings based on the presence and absence of reproductive organ. This is the first report of the species from the Tripura region. Local ethno-medicinal use of the Tripuri tribe is also documented.
