The Xerces Society is an international non-profit organization dedicated to protecting biological diversity through invertebrate conservation. The Society advocates for invertebrates and their habitats by working with scientists, land managers, educators, and citizens on conservation and education projects. Our core programs focus on endangered species, native pollinators, and watershed health.



Current Programs

Aquatic Macroinvertebrate Biomonitoring. Monitoring invertebrates in a stream is a valuable method of assessing the health of a watershed, bringing biological monitoring to the grass-roots level. The program has provided training and technical assistance to hundreds of volunteers and professionals across the Pacific Northwest. We will use this program to expand our conservation and education efforts in other freshwater and marine habitats.



Pollinator Conservation. Increasingly, human activity disrupts the vital ecological service that pollinators provide. We collaborate with land managers to implement habitat improvements, and work with local communities, agencies, and scientists to promote habitat restoration, training workshops, and education activities.



Protecting Endangered Invertebrates. We are working to protect rare, threatened, and endangered invertebrates and their habitat across the United States. We work with land managers, scientists, and other conservationists to ensure that these "at-risk" species will continue to grace our world in the years to come.
