Saturday 16 September (Geoconservation Day): Wren’s Nest. Directed by the reserve wardens. Meet for a 10.30 start at the Warden's office adjacent to the former Mons Hill college. Approach along the access road leading into the new development adjacent to the Caves Pub on Wrens Hill Road. The day will involve scrub clearance and a 'geo-blitz' to record findings. Bring gloves, stout footwear and packed lunch. Wardens will provide tools, hard hats if necessary and a hot drink. Finish around 2.30.
