Our Work | Species | Weasel
The weasel (Mustela nivalis) is widespread and thought to be relatively common across Britain, but is under-studied and poorly understood.
Traditionally, gamebag data collected by gamekeepers have been used to record the distribution and abundance of weasels, although the accuracy of these data has been questioned. There is a need to develop an effective survey methodology to monitor population trends in the species.
The Trust has previously developed baited hair-tubes and these were deployed to detect weasels in west Wales as part of the MISE Project.
Currently, we are trialing methods to study weasels and we are working in collaboration with the Dutch Small Mustelid Foundation to trial the ‘Mostela’ which was developed in the Netherlands to monitor weasels and stoats.
