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!

A Scientific Review of Causes, Consequences, and Management Alternatives
This report outlines key aspects of bark beetle outbreaks, their relationship to fire risk, and presents alternatives to large scale logging practices. Additionally, it suggests that government efforts to stem the infestation of insects in forests across the American West may be ineffective and are unlikely to mitigate future infestation or decrease wildfire risk. In fact, government efforts to cull and control insect outbreaks, which play “an important role in the development and maintenance of forest,” could have significant short-term and long-term impacts on national roadless forests, according to the report. Currently, state and federal agencies continue to spend millions to battle spreading mountain pine beetles and other insects across western states. In recent years, mountain pine beetles have infested millions of acres in Colorado, Wyoming and Montana.
The Science Behind the Role These Insecticides Play in Harming Bees. 2nd Edition; Revised & Expanded
Now availaible as a revised and expanded second edition, our report examins the science behind the role these insecticides play in harming bees.
Washington State
The objective of this conservation strategy is to identify geographic areas within the state of Washington with the highest potential to support rare and declining bumble bee species and provide guidance and recommendations for management of those areas. Maintaining sufficient populations of each focal species is essential to the long-term persistence of these animals. This will require protecting and enhancing habitat for foraging, nesting, and overwintering, while ensuring connectivity between habitat areas, across jurisdictions.
The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. The IUCN Red List Categories and Criteria provide an easily and widely understood system for classifying species at high risk of global extinction, so as to focus attention on conservation measures designed to protect them. This latest version of the classification system was adopted by the IUCN Council in February 2001 and reflects comments from the IUCN and SSC memberships and the final meeting of the Criteria Review Working Group.
Distributions, Threats, and Conservation Recommendations
Anecdotal reports of firefly declines have been on the rise in recent decades. While population declines have been documented for some species in Europe and Asia, the picture was not as clear in North America. With the exception of a few localized studies, no effort had previously been made to assess the conservation status of the 171 described taxa in the United States and Canada.
