Event Info

This will be the fourth year the annual nest count has taken place in partnership with Sorby Mammal Group and Roseanna from the DVLP Team. The last three years have seen a steady increase in discarded harvest mouse nests left over from the summer months when they are most active.

Worsbrough Mill & Country Park is one of the best areas for harvest mice locally, due to the habitat availability and preference’s of the female mice when making their nests to rear their young. Annual data allows us to monitor territories and any changes in population which is vital to protect the species.

Volunteers will meet at 11.00am the free car park for the TPT near Wigfield Farm at SE343037. We will then venture out on site focusing predominantly on the reeds within the wet woodland to search for discarded summer nests and signs of harvest mouse occupation.

The aim is to map the areas used by harvest mice and to compare nest counts with previous years so we can continue to monitor and protect such an important and threatened species.We are hoping to make this an annual monitoring project.

Wellies and sensible outdoor clothing is strongly advised, as are strong gloves for searching in reeds. No experience required. Please book in advance if possible using the details below.
