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.).
Known only from southern Oregon and northern California between the Coast and Sierra Cascade Ranges, Franklin’s Bumble Bee has the most restricted range of any bumble bee in the world. Its entire distribution can be covered by an oval of about 190 miles north to south and 70 miles east to west. However, there has been a precipitous decline in numbers and localities of occurrence since 1998. No Franklin’s Bumble Bee were observed during surveys in 2004.
