One initiative has already begun to address the need for further monitoring of climate change impacts. The ECN Central Coordination Unit, working with the national conservation agencies, has developed plans for a network of sites to monitor the effects of climate change on biodiversity at designated conservation sites, using a subset of ECN measurements. An initial pilot study of ten upland sites in England, Scotland and Wales was adopted as a practical first objective given the limited resources available (Sier, 2005a and b) and two initial sites (Creag Meagaidh NNR and Ingleborough NNR) have started.
