The funding from the Woodland Trust's Community Woodland Network aims to encourage the sharing of information and resources.
Over 200 groups have signed up since the website was launched in 2003 and 94 grants have been issued.
Community Woodland Network manager Paul Bunton said: "Grants give groups the chance to invest more in their projects to sustain them longer term."
Stuart Hislop, a member of the Drews Pond Woodland Project in Wiltshire, said its grant paid for the planting of a wildflower meadow on derelict land around a former asylum.
The application deadline is 30 June. For more information, contact the Community Woodland Network.
