| description | Plant diversity in the wetlands of Phobji and Gantey represents an important aspect of the overall
wetland ecosystem. However, over the years, the increasing trend in population has initiated the
building of many infrastructures and accommodations which lie at close proximity to the core wetland
area. This accelerates the expansion of land use to the core wetland area posing a huge threat to the
plant diversity of the wetlands. This research thus studied the plant diversity in human settled area
and core undisturbed area with an objective to assess the influence of human settlement on the plant
diversity. A belt transect method was used for the purpose of vegetation survey and Shannon Wiener
diversity was calculated using the relative dominance. Plants were analyzed for their diversity,
richness, life forms, dominance and invasive nature. Additionally, soil and water parameters were
also tested to see the current situation of the pH and nutrient levels.
A total of 136 species belonging to 39 families was identified in both the areas. Some of the dominant
species identified were Trifolium repens, Rumex napelensis and Pedicularis denticulata. An endemic
plant species Euphrasia bhutanica was also identified in one of the plots of the undisturbed areas.
Two species of orchid was also found along with the endemic plant. Shannon Wiener diversity index
showed the highest index of 3.14 in one of the plots in human settlement area. The overall diversity
index and species richness was found to be higher in the undisturbed areas. Soil analysis did not show
much of a difference in physical and chemical parameters except for a slight difference in potassium
content. Similarly, water parameters did not show much difference but only showed variation in
calcium content.
The findings of the study indicated towards the increasing influence of human settlement in the
wetland. |
