Plants are the backbone of life on Earth and an essential resource for human well-being. Yet despite our reliance on plants, as many as 100,000 plant species are threatened with extinction in their native habitats around the world.

On May 18, join botanic gardens and zoos throughout the U.S. in celebrating Plant Conservation Day. This online toolkit gives you all the resources—background, promotional materials, and education activities—you need for a successful Plant Conservation Day at your site. Follow the links in the toolbar above to start planning!

Plant Conservation Day is a joint project of the Association of Zoological Horticulture Inc. and Botanic Gardens Conservation International.
