Pollinator Conservation Resources for Washington, D.C.

Welcome to our Pollinator Conservation Resource Center! The Xerces Society produces dozens of publications each year to inform and guide conservation efforts and to share the latest science-based conservation information. You can browse the list below or filter results by publication type, keyword, or a combination of the two. When filtering by keyword, we suggest leaving the publication type as "any" to show the widest number of results.

The goal of this tool is to evaluate pollinator habitat at a given urban, suburban, or rural site and identify areas for improvement. This process will also help users prioritize the most essential next steps to take for pollinators at the site.
Pollinators are essential to the health of our environment and for bountiful farm crops. There are four straightforward steps that you can take to help them: grow flowers, provide nest sites, avoid pesticides, and share the word.
Minimizing Risks to Pollinators and Beneficial Insects
Even pesticides allowed for use in organic agriculture can cause harm to bees and other beneficial insects. This guide provides a brief overview of how to select and apply pesticides for organic farm operations while minimizing pollinator mortality.
A Comparative Overview
This fact sheet is intended to be a quick reference to help you select and use organically-approved pesticides with the least impact on bees and other beneficial insects.
Most of North America’s native bee species only forage over a distance of a few hundred yards, so with a little planning, your yard can provide a safe space for bees and other pollinators to thrive.
This fact sheet delves into how these impacts on pollinators occur, and offers mitigation measures and alternative pest management strategies.
"On behalf of our millions of members and supporters, the undersigned organizations and companies are writing to urge you to protect pollinators in the next Farm Bill."
Restoring monarch habitat, including roadsides, is important to the species’ recovery. A diversity of milkweed species is found on roadsides, on which readily monarchs lay their eggs, but roadsides provide more than just milkweed. They can also provide diverse nectar sources to feed adult monarchs and other pollinators. This guide highlights best management practices to reduce the impacts of herbicides on monarchs.
A diversity of milkweed species is found on roadsides, and play an important role in supporting the life cycle of monarchs. This guide can help you recognize the most common native species of milkweed on roadsides in your region.
Land managers and land owners can bring wildflowers back to low diversity, established grass stands through a process known as interseeding. This publication provides guidelines and specific strategies for interseeding wildflowers into established grasslands and identifies species of wildflowers most likely to establish and persist in the Midwest and Great Plains.
Fall 2014
An update of the Xerces Society's monarch conservation efforts to date.
Reports of the IUCN Bumblebee Specialist Group are available at their website:

Wild monarch butterfly populations have declined by an estimated 90% in the past two decades, due to habitat loss primarily in the Midwestern U.S., where these migratory butterflies spend the summer months. Monarch butterflies are routinely purchased from commercial growers for release at weddings, funerals, and other celebrations, and to raise in classrooms and exhibits for educational purposes. Out of concern for monarch conservation, some private citizens are also rearing hundreds to thousands of monarchs in backyard operations for release into the wild.

For financial, health, and cultural reasons, serious declines in pollinator populations are causing global alarm. Many electric power companies are concerned about the decline in pollinators and would like to understand more about pollinator science, conservation opportunities, and associated costs and risks. Through management of large real estate assets, there is ecological potential to enhance pollinator habitat through well-designed, ecologically meaningful, and cost-effective actions on property that power companies manage. This technical brief provides an overview of pollinators, considerations for power companies, and an introduction to conservation strategies.
An Identification Guide

More than ever before, there is widespread interest in studying bumble bees and the critical role they play in our ecosystems. Bumble Bees of North America is the first comprehensive guide to North American bumble bees to be published in more than a century. Richly illustrated with color photographs, diagrams, range maps, and graphs of seasonal activity patterns, this guide allows amateur and professional naturalists to identify all 46 bumble bee species found north of Mexico and to understand their ecology and changing geographic distributions.

This fact sheet for growers provides information and resources to encourage nurseries to grow native milkweed.
Monarch Butterfly Nectar Plant Lists for Conservation Plantings is a helpful tool for ecological restoration, providing lists of plants known to support monarch adults and caterpillars.
Agroforestry Note #34, General #8 [Agroforestry Notes, February 2007]
This fact sheet from the USDA National Agroforestry Center provides an overview of ways to enhance landscapes to support native bees.
