  • Title
    Plant species composition on two rock outcrops from the northern Western Ghats, Maharashtra, India
    Type
    Journal Article
    Description
    The Western Ghats are full of high altitude plateaus/rock outcrops amidst mesic forests. Throughout the world, rock outcrops are isolated habitats and known for their uniqueness with respect to environmental variables and biodiversity and well known as centers of species endemism. In India such special habitats are geographically known but very less information is available about their floristic wealth. Available studies are occasional and limited to ecology. Due to a lack of appropriate information and errors in the study models of random sampling, important habitats may get misinterpreted and pose a threat to conservation. A comprehensive botanical study of two rock outcrops, Durgawadi Plateau (DP) and Naneghat Plateau (NP), on the escarpment of the northern Western Ghats revealed a very high within-site (360 taxa on DP and 249 taxa on NP) and between-site plant diversity totaling to 443 taxa of specific and infraspecific ranks. The individual outcrop areas are very small (2.8793km2 and 0.7524km2 respectively for DP and NP) but harbor a huge diversity of flowering plants. The commonly shared taxa are relatively low (37% of the taxa recorded) indicating that the two outcrops are floristically very distinct from each other. They are also distinct in terms of soil composition, though on the same crest line of Sahyadri and quite close to each other. The study emphasizes the need for micro-level inventories of smaller areas by taking intensive surveys for documentation of different aspects of the abiotic and biotic diversity as well as other environmental and anthropogenic variables.

    CEPF Western Ghats Special Series: Avian collision threat assessment at Bhambarwadi Wind Farm Plateau in northern Western Ghats, India
    Type
    Journal Article
    Description
    To address the shortage of power in India, wind energy is increasingly harnessed as an alternate and renewable energy source. There is a rapid increase in the number of wind farms at suitable sites all over the country. Some of the key sites with optimal wind velocities are the plateaus on the Western Ghats - a global hotspot of biological diversity. The rocky plateaus on the Western Ghats are terrestrial habitat islands facing extreme micro-environmental conditions; however, scanty information is available on the ecology of these plateaus. We undertook a two-year study to assess the impact of wind farms on birds. We also documented the avian diversity at Bhambarwadi Plateau, northern Western Ghats, India. To the best of our knowledge this is the first such study in India. We recorded 89 avian species on the plateau, 27 of which flew in the risk area swept by the rotor blades, and hence are potentially at risk of collision. The collision index (the number of bird collisions with wind turbines over a period of one year assuming that the birds do not take any avoidance measure) for these species were estimated. We also identified species at risk from collision with transformers and wind-masts, and at risk from electrocution. Reduction in avian activity in the study area was evident with progress of wind farm erection. Despite the small footprint of an individual wind turbine, the associated infrastructure development causes wider habitat modification and destruction resulting in a displacement effect. Therefore, wind farm erections in strategic locations such as biodiversity hotspots should be subject to prior site based strategic environmental assessments (SEA) as well as environmental impact assessment (EIA) studies.
