  12. 12.  The higher number of rare species in the study area is important for conservation point of view.  It is concluded that the bird analysis study site exhibits diverse homegarden habitat and is rich in bird species. The wide variety of the bird species like hornbills, woodpeckers, warblers, drongos, flycatchers, kingfishers, starlings, crows and kites indicates richness and diversity of the bird species in the study area.  Our study highlights the importance of conducting and documenting bird diversity at different land-use type. It is important to carry out repeated inventories of the Konkan coast in order to track regional and global changes in population of bird species.  The study demonstrates rich floral and avifaunal diversity of homegardens.  Therefore, the priority should be given to the region for conservation and sustainable management of floral biodiversity of homegardens, which is facing pressure from increasing population, land-use changes, deforestation and developmental activities.  The variation in species richness, dominance and diversity for homegardens vegetation components indicate dynamic nature.
  13. 13.  Although ornithological knowledge of the Western Ghats is significant, understanding the avifaunal diversity is still important for conservation planning and restoring ecosystems in long term management. We therefore suggest further systematic and long term avian survey to document changes in overall species richness and diversity in Konkan coast of Western Ghats.  Being an ecological indicators as well as aesthetic reasons it is important to understand how birds are affected by human induced land-use changes. Therefore, it will help for better conservation planning of avifauna of the study area in the future.  The outcomes of our study will provide baseline data for monitoring and conserving the vegetation and avifaunal diversity of tropical homegardens vegetation and other land-use types.  The present study conclude that land clearing, land breaking and nuclear power project installation will affect the biodiversity and carbon balance. Therefore, the study suggests that it should not be started at Jaitapur for future environmental health, safety, public health, security and to avoid future hazards of loss of biodiversity.
