Description

Data from the Norwegian breeding bird monitoring scheme from 2006 up until today. The project is carried out in cooperation between BirdLife Norway, Norwegian Institute for Nature Research (NINA) and the Norwegian Environment Agency, and is the most important project for monitoring population trends for Norwegian bird species on land.

Purpose

New data will be made available after quality control is finished, normally at the start of the following year.

Sampling Description

Study Extent

The samples are made in grids with 20 counting points (some grids have fewer points due to lack of accessibility to points, first-year sampling have determined any points which should be excluded). Counting points are found by the use of a GPS. The exact counting point used should be chosen within a distance of up to 20 m to the point that the GPS indicates. A selection of species are also counted when moving between counting points.

Sampling

Exactly 5 minutes registration is made at each point. Counting of birds starts after the observer is in place at the point and things have calmed down. Birds frightened away by the observer shall not be recorded at the sampling point if they are not observed within the five minutes the registration takes place. Such cases are recorded in the line sampling if the species is relevant there.

Quality Control

By regional contacts in Birdlife Norway and by project coordinator in NINA
