The CGBD organizes Working Groups to target attention on selected topics and to explore the process of strategic, collaborative grantmaking. Working Groups of 25-50 interested funders convene on a regular basis through conference calls and meetings.

The CGBD produces BIODIVERSITY, a quarterly newsletter for members, interested organizations (NGOs) and individuals. The newsletter contains research articles, briefs on issues related to biodiversity, a schedule of important events and highlights of recent projects and member activities.

The CGBD secretariat meets with NGO representatives at their request, at staff invitation, or CGBD member request. The secretariat does not recommend proposals or projects to members. It offers advice on and may suggest possible avenues for support.
