2. Application of GIS in Plant Taxonomy, Species Distribution and Ecology

C. Sudhakar Reddy



Abstract

The use of Geographic Information System (GIS) in of plant taxonomy, ecosystem management and various components of biodiversity is reviewed. Incorporation of geo-referenced ground data brings out the drive areas of habitat shrinkage and species loss. Satellite remote sensing offers global coverage and continuous measures across space at high spatial and temporal resolutions. The review demonstrates the use of geographic information technology in mapping and monitoring of species and habitats, gaps in the exploration and conservation, characterization of habitat and landscape level biodiversity, species distribution pattern and modelling, threat evaluation from species to ecosystem level, delineation of ecological corridors and intact forest landscapes, hotspot analysis, modelling of forest cover change and analyzing relationship of plant functional types and climate. Integrated analysis of vegetation types, disturbance regimes and biological richness will be useful for designing optimal sampling and identifying sites for systematic inventories whereas gap analysis help to know the status of botanical exploration and the representativeness of protected area network.
