Community groups are smaller organisations than the big conservation non-government organisations, and have their base in a smaller local area. They may be incorporated bodies such as trusts, or friends of a national park, or groups of volunteers who have banded together to protect a valued local environment.
They are often passionate and knowledgeable about the biodiversity values of a local area, and particularly effective in mustering support from volunteers to manage the land they protect. Most community reserves are prized by local residents, and venues for school children to learn first hand about Australia's flora and fauna. Often they attract visitors from further afield, bringing jobs and cash flow to the local economy.
