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.
Bumble Bee Conservation
Many formerly common North American bumble bees are now in steep decline; we have been documenting their status in order to better conserve them.
Western Freshwater Mussels
We are working to understand the status of western freshwater mussels; anecdotal evidence suggests they have experienced dramatic population declines.
The Xerces Society works to protect the sites where monarchs thrive, breed, migrate, and overwinter.
Red List of Aquatic Invertebrates
We are creating a Red List of the most vulnerable aquatic invertebrate species; our goal is to raise awareness and provide conservation tools before these animals decline to a level where recovery is impossible. Read more
Red List of Bees
An online list of species profiles that review the status of approximately fifty North American bees that are most at-risk of extinction.
Red List of Butterflies and Moths
An online list of species profiles that review the status of the approximately fifty North American butterflies and moths most at-risk of extinction.
Pacific Northwest Butterflies
We advocate for the conservation of many Pacific Northwest butterflies by collaborating with state and federal agencies and private landowners.
