Sofia Hedman will do her Masters thesis (at Umeå University), partly in our Goodstream measures. A large number of specially developed ”camera traps” will be used to investigate populations and individual movemenet patterns of Mustelids (polecat, mink, otter etc). In total 47 cameras are deployed in 4 catchment areas and several of the them (17) will be located along Trönningeån. The picture shows one of the camera traps.
