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.).

"Rapid butterfly declines across the United States during the 21st century" is a study published in Science. The study found that populations of butterflies across the United States are declining. In addition to dramatic declines for individual species, the study concluded that total abundance of butterflies has declined by 22% from 2000 to 2020. That means that for every five butterflies seen 20 years ago, now there are only four.
