As a BCA member club, the TSG encourages its members to be responsible for the caving environment, and the Cave Conservation Code is a simple set of suggestions for maintaining that environment:
Cave Conservation Code
1 Cave with care and thought for the environment.
2 Disturb nothing whether living or geological.
3 Avoid touching formations.
4 Keep to marked routes and never cross conservation tapes.
5 Take nothing but photographs.
6 Do not pollute the cave, leave nothing behind.
Further useful information can be found in the BCA/BCRA Minimal Impact Caving Guidelines leaflet, available to download below.
