Try searching this site by country and browse the NGO's that are working there. You never know what you will find. This search engine was developed by David Oldenkamp at Indiana University and James Jacobs at Stanford. The website is from UC Berkeley.
From the International Union for Conservation of Nature and Natural Resources, this database provides taxonomic, conservation status and distribution information on all kinds of species. NOTE: Read the introduction for what is and is NOT included in the database.
To search by country, select "Other Search Options" then "Location" for a list of endangered speices by region.
Countries where WWF maintains offices are listed on the side. Some countries will clearly label environmental issues or problems. For the rest try a general search under country name and "environment" or "pollution" or even just a country name and see what comes up. If the site is not in English, look for a tab (flag, or something labelled "English").
You can also just search in the main WWF page, http://wwf.panda.org/
