Grebes are specisalised waterbirds which inhabit marshlands and reed-fringed lakes. Their dependence on wetlands is total and as a result they are particularly vulnerable to changes in ecosystems and their deterioration.

Over the last 30 years the African wild dog population has declined dramatically. Dogs have disappeared from 25 of the 39 countries in which they were previously found, and only 6 populations are believed to number more than 100 animals.
