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.).
In 2018 and 2019, the number of monarchs overwintering in California dropped to 1% of the historic population size. In 2020, that number dropped even further to less than 0.01% of the historic size, volunteers counted less than 2,000 monarchs during the annual Western Monarch Thanksgiving Count. For every 2,250 monarchs there were 30 years ago, there is only one left flying today.
The Xerces Society joined a group of environmental and health organizations to petition the California Department of Pesticide Regulation to regulate the planting of crop seeds coated with systemic insecticides. California's pesticide regulatory system has a loophole that allows for unchecked use of insecticide-coated seed on farms throughout the state. Neonicotinoid insecticides are commonly used as seed coatings, resulting in significant contamination of California's waterways and ecosystems as they move off-field.
