As a science-based organization, the Xerces Society produces dozens of publications annually, all of which employ the best available research to guide effective conservation efforts. Our publications range from guidelines for land managers, to brochures offering overviews of key concepts related to invertebrate conservation, from books about supporting pollinators in farmland, to region-specific plant lists. We hope that whatever you are seeking—whether it's guidance on making a home or community garden pollinator-friendly, advice on developing a local pesticide reduction strategy, or detailed information on restoring habitat—you will find it here!
Use the search functions to sort by publication type (books, guidelines, fact sheets, etc.), location, and/or subject (agriculture, gardens, pollinators, pesticides, etc.).
The Xerces Society opposes rescission of the definition of “Harm” under the ESA, Docket No. FWS-HQ-ES-2025-003. We respectfully submit the following comments in strong opposition to the proposed rule that would rescind the regulatory definition of “harm” under the Endangered Species Act (ESA). If enacted, this action could undermine implementation of the ESA by creating confusion about its protections and weakening deterrents to habitat destruction.
On August 18, 2020, the Xerces Society filed a petition to list the western ridged mussel as an endangered species under the U.S. Endangered Species Act. The western ridged mussel has been lost from 43% of its historic range. In addition, sudden die offs of western ridged mussels have been observed in Oregon and Washington.
About 25% of all known organisms on the planet are animals that live in the soil through all or a portion of their lives. The majority of these animals are invertebrates that interact with microbes, plants, and each other, forming the life of healthy soils.
The Xerces Society submitted this petition for listing the loopy five firefly (Photuris forresti) under the Endangered Species Act (ESA) in 2023.
