Geo-gardening at Trendlewood Quarry, Nailsea

Geo-gardening - Sunday 3rd February 2013

On Sunday 3rd February 2013 a Joint Gardening Force (JGF) from Friends of Trendlewood Park (FoTP) and Avon RIGS Group descended on Trendlewood Quarry in Nailsea and proceeded to spend a few hours clearing ivy and other encroaching vegetation from the lower parts of the quarry face in three areas.

These three areas were selected to demonstrate the differing bedding types – from varves to massive -  in this Pennant Sandstone of the Downend Formation and the differing types of deposition – point bars and channel deposits.

This is the first part of the implementation of the quarry management plan that was agreed at a site meeting between N Somerset Council, Friends of Trendlewood Park and Avon RIGS Group. The second part which will be carried out by the N Somerset Green Team will consist of clearing the upper levels of the face and removing a few selected trees that are in danger of falling and have extended their roots into the joints and fissures rock close to the face and so are damaging the exposure.
