Resilience of the tropical dry evergreen forest in the human-impacted region of Coromandel Coast, India

Abstract : An assessment of the resilience of Tropical Dry Evergreen Forest (TDEF) formation was made using quantitative vegetation and surface soil pollen surveys in 14 sites around Pondicherry within the heterogeneous landscape of the Coromandel coast of southern India. The sites for vegetation and soil surface pollen samples were selected using a stratified random sampling. Vegetation or land cover quantities were measured in quadrats where 325 angiosperm species representing 75 families of Angiosperms of the present vegetation were recorded. The relative densities of species evaluated from three distinct sites helped to compare them across time, the trajectory of individual species and the TDEF itself. The vegetation study indicates that some of the TDEF species have the ability to ‘recover’ and adapt to changing conditions and anthropogenic pressures. The study also demonstrated the significance of the use of pollen to reconstruct the past land cover.
