4 distinct species

Across the time series Tetrastes bonasia is the most frequently occurring species

Methods

The abundance of the tetraonid species in different parts of thecountry. the long-term population trends in respective areas and thedelimitation of areas in which the fluctuations of a single tetraonid species aresynchronous were studied. Route censuses of tetraonids give only relativedensities. because they are carried out in optimal grouse habitats. but thecensus results are suitable for the purposes mentioned above. Between 500and 800 route censuses are carried out annually; the total length of theseroutes has varied between 20.000 and 30.000 km annually. Unit of abundance = MeanCount, Unit of biomass = NA
