India with diverse forests and equally diverse vegetation types
Out of 17000 species of flowering plants 2863 species are trees
About 69 percent (228 million ha) of India is • dry land – arid, semi-arid and dry sub-
humid• heavily populated• livelihood and food security
Three major programs on tree diversity at ATREE
1. Mapping and monitoring tree diversity and estimating value of ecosystem services
2. Understanding and enhancing the role of tree diversity in livelihoods , using participatory approaches.
3. Restoring tree diversity, also using participatory approaches

Effective management for conservation requires disentangling the effects of different drivers to identify those mostresponsible for species decline.
