| Abstract: | Landscape ecology, inter alia, addresses the question as to how altered landscape patterns affect the distribution, persistence, and abundance of a species.
Landscape ecology plays an important role in integrating the different scales of biodiversity from habitat patch to biome
level. Satellite remote sensing technology with multi-sensor capabilities offers multi-scale information on landscape composition
and configuration. Advances in geospatial analytical tools and spatial statistics have improved the capability to quantify
spatial heterogeneity. Globally, landscape level characterization of biodiversity has become an important discipline of science.
Considering the vast extent, heterogeneity, and ecological and economic importance of forest landscapes, significant efforts
have been made in India during the past decade to strengthen landscape level biodiversity characterization. The generic frame
work of studies comprises preparation of national databases providing information on composition and configuration of different
landscapes using multi-scale remote sensing techniques, understanding the landscape patterns using geospatial models to elicit
disturbance and diversity patterns and application of this information for bioprospecting and conservation purposes. Studies
on hierarchical linkage of multi-scale information to study the processes of change, landscape function, dynamics of habitat
fragmentation, invasion, development of network of conservation areas based on the understanding of multi-species responses
to landscape mosaics, macro-ecological studies to understand environment and species richness, habitat and species transitions
and losses, landscape level solutions to adaptation and mitigation strategies to climate change are a few of the future challenges.
The paper presents the current experiences and, analyses in conjunction with international scenario and identifies future
challenges of Indian landscape level biodiversity studies. |
