Coppetts Wood and the Glebelands were designated a Local Nature Reserve by the Borough of Barnet in 1997. You can find a map of the reserve here. The Reserve has five distinct sections, with different habitats: Coppetts Wood, the Scrublands, Coppetts Close Triangle, the Green Link and the Glebelands. The Natural England website has more information on the Reserve.
The Coppetts Wood Conservationists meet on Sunday mornings throughout the year with the aim of maintaining the nature reserve, increasing its biodiversity and enjoying some sociable exercise. If you come along, you could find yourself digging a new pond, or raking out an old one; clearing bushes or bramble to encourage a more varied habitat, planting trees or a hedge. Volunteers span an age range from two to eighty-two.
