Mustelid trap catch 12 months to July 2017

Ark catch map 2017

Every year, early Summer sees an explosion in the number of invading mustelids, as the females leave their nest and take their litter with them. Regularly there is a concentration of catches on the periphery, but this year there has been a higher presence in the internal areas. The reason for this is not apparent, as there is not a similar pattern in rat presence.
