Lough Neagh has lost three quarters of its winter water birds

Wildlife Extra News - Largest lake in British Isles has lost three quarters of winter water birds
The study, by Quercus, Northern Ireland’s Centre for Biodiversity and Conservation Science, found the number of diving ducks migrating to the lake for the winter months has dropped from 100,000 to less than 21,000 in the space of a decade.
 The research, published in the journal Freshwater Biology, found the ecosystem of the lake has dramatically changed since 2000/01 leading to a huge decline in the numbers of insects and snails living at the bottom of the lake. This combined with the effects of global climate change dramatically affected the numbers of migratory and overwintering water birds, a feature for which the lake is designated a Special Protection Area.
