In August each year, grouse and forest birds are inventoried using standing bird dogs along predefined line transects across the country. Data from the line transect sampling is registered and stored in "Hønsefuglportalen".
The portal is owned and operated by the Norwegian Institute for Nature Research (NINA), and is utilized by several public and private land owners. NINA is, together with the Inland University of Norway (INN), responsible for analysing the data and reporting the results to stakeholders prior to the start of the hunting season.
Look at data and estimates to view time series. The overview only includes public stakeholders affiliated with Hønsefuglportalen.
Hønsefuglportalen app is available in Google Play for Android and in Appstore for iOS/iPhone
