Population trends of selected bird species show that the state of the environment in the cultural landscape is still deteriorating, especially in some parts such as Prekmurje and Ljubljansko barje. The population of selected forest bird species is stable, however, a trend of deterioration of its habitat was recorded in recent years, as a result of intensified logging. Bird populations that winter on Slovenian rivers and other water bodies have different trends that are mostly in line with trends of regional biogeographic populations of waterbirds in Europe.
