Across the time series Martes martes is the most frequently occurring speciesMethods
The tracks of red fox. pine marten. stoat and pygmy weasel crossing an observation line 5970 m long running westwards from the summit of Varriotunturi were counted in the winters of 1968/69 - 1980/81 by skiing along this line once a week during the snowy season of the year. Only tracks that were at most 2 days old when recorded in November - April are taken into account in the present calculations. If the same individual had crossed the line more than once within a few minutes at points lying between two recording sticks 20 m apart. this was regarded as only one crossing. In order to render the results for the different months comparable. all monthly means (per 100 m of the observation line) were calculated per four observation times on the basis of those observations in which fresh tracks were visible. Unit of abundance = MeanCount, Unit of biomass = NACitation(s)
