TCV (The Conservation Volunteers) have a Croydon ACE team (Action for Croydon’s environment) that have their head quarters in Coombe Woods . The ACE team carry out many hours of conservation each year. Just an example relevant to Croydon Central Parks is the removal of bracken from Addington Hiils , to prevent the heath from disappearing.
In Coombe Woods they have been busy repairing damaged fencing and clearing fallen trees to sustain the paths , marked by logs , within this award winning wood. ACE also carry out work in many other local parks and are always keen to hear from volunteers to join their work days. You can find further details from their website.
