Long-term bird population changes in the protected areas of Finland under climate change Climate warming causes poleward shifts of species ranges and populations. Also in Finland both ranges (Ref. 1) and mean weighted densities (2) of species have shifted northwards during the past 40 years. Moreover, climate change and other human influences such as land use and hunting may cause changes in population sizes. Protected area (PA) network is one of the key instruments to maintain biodiversity in a changing climate and alleviate abrupt changes in species distributions and densities (3). In order to analyze the ability of nature reserves to maintain populations we compared the observed changes …
