Publications Library

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!

To better inform consumers about the plants and seeds they buy, a state could require labeling of plants and plant materials that have been treated with a neonicotinoid. Retail establishments can also institute such labeling voluntarily, and some already have.

Imagine that the city of Los Angeles had shrunk to the size of the town of Monterey. You’d be shocked. Basically, that is what has happened to the monarch butterflies that overwinter in California. At Thanksgiving 2018, the population of western monarchs hit a record low of less than 29,000 butterflies, a decline of 99.4% since the 1980s, when the number of monarchs flying to California for the winter is estimated to have been 4.5 million. For every 160 monarchs there were 30 years ago, there is only one left flying today.

Western monarchs need everyone’s help. In 2018, the population hit a new low, less than 29,000 butterflies—a loss of more than 99% since the 1980s. This Western Monarch Call to Action aims to provide a set of rapid-response conservation actions that, if applied immediately, can help the western monarch population bounce back from its extremely low 2018–19 overwintering size. Long-term conservation effort is needed to rebuild the western population of monarchs. The goal of this call to action is to identify actions that can be implemented in the short-term, to avoid a total collapse of the western monarch migration and set the stage for longer-term efforts to have time to start making a difference.
Based on the best available data for when and where monarchs breed in the West, we have developed regionally appropriate monarch breeding habitat management windows, when management activities are least likely to have negative effects on monarchs.
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.
