Why you should join the OCA

All around the world, orchids are disappearing because their habitats are being taken for agriculture, mining, development, or some other human activity. Joining the OCA puts you together with hundreds of others who are working to protect orchid habitats. The OCA is the premier US organization focusing its efforts on protecting tropical orchid habitats. Other groups, such as Conservation International and the World Wildlife Fund, are also working to conserve tropical habitats, but the OCA is the only one to focus on orchids. Thus, if you are an orchid lover, the OCA is your natural conservation choice.

In addition to the sure knowledge of your good works, membership in the OCA entitles you to priority inclusion in our Orchids in the Wild® trips and guarantees you e-mail delivery of our periodic newsletters. Your donations are used only for conservation; we have no paid employees and our directors serve pro bono. Because the OCA is a 501(c)3 public charity, your donations are fully tax deductible. Join now!
