Founded in 1972, the Woodland Trust is the UK’s leading woodland conservation charity and has four main aims: to prevent the further loss of ancient woodland, while expanding the area of new native woods; to restore and improve woodland biodiversity; and to increase people’s understanding and enjoyment of woods.

Eco-friendly cards: recycled envelopes, paper from sustainable forestry, compostable outer slips.
