Data description

Grimsö wildlife monitoring: red fox reproduction data

Last changed: 18 June 2024

Data from a monitoring programme of red fox (Vulpes vulpes) reproduction in the area around SLU Grimsö Wildlife Research Station. Each year, during weeks 22–26, all known dens in the vicinity of the station are visited and several indicators are examined at each den to determine whether it is used for reproduction during the year.

The number of dens visited varies from year to year due to forestry activities but has been between 150 and 230 since the mid-1970s.

Evidence of use by badgers (Meles meles) is also noted but is not included in this dataset.
