Forests are the most important habitats for a large number of Norway’s bird species, and just over one third of all breeding bird species are mainly associated with forests. At present, the total area of forest in Norway is increasing and the average age of the trees is rising. However, the area of undisturbed natural forest is shrinking.

The population index in the figure above is based on combined figures for 24 forest bird species, and shows that breeding populations of Norway’s most common forest species have been relatively stable over the past 20 years. Populations of most of the 24 species, for example blackbird, chaffinch and hedge accentor, have been stable in the period 1996–2017, while some species, such as the song thrush and chiffchaff, have shown a small rise, and others, including the robin and tree pipit, have shown a small decline.  

Many of the species that are most strongly associated with natural forests are less common, and population trends for these species have not been registered.
