The Xerces Society is a nonprofit organization that protects wildlife through the conservation of invertebrates and their habitat. For forty years, the Society has been at the forefront of invertebrate protection worldwide, harnessing the knowledge of scientists and the enthusiasm of citizens to implement conservation programs.
In June, Oregonians were stunned by the mass death of over 50,000 bumble bees outside of Portland, Oregon, caused by an insecticide available in any garden store or home center. Xerces is an effective national and international voice for science-based conservation advocacy and we need your immediate involvement to expand our work and protect invertebrates from events like this one.
