Endangered Species

The Xerces Society collaborates with scientists, land managers, and conservationists to raise awareness about the plight of invertebrates and to gain protection for the most vulnerable species before they decline to a level at which recovery is impossible. Destruction of habitat, introduced species, and pesticides are all leading to the loss of invertebrate species.
