It's simple: We work to secure a future for endangered species, and your contributions make our work possible.

We don't spend a lot of time or money promoting ourselves — we put our members' donations directly to work saving wild creatues and the wild places they call home.

However you give, your support provides vital life support to the plants and animals that need it most.

If you're interested in making a philanthropic or planned gift, or making a gift of stocks or securities, please contact Chief Development Officer Paula Simmonds at (646)-770-7206 or email psimmonds@biologicaldiversity.org.
