Press & Media

The Xerces team includes nationally recognized experts on a range of issues, including pollinator conservation, pesticide impacts, habitat creation, and protecting endangered species. We work to understand and protect insects and other invertebrates in all landscapes, from wildlands to backyards.

Our staff is known as a reliable source of science-based advice at the forefront of invertebrate protection, and can provide information and perspective on all aspects of invertebrate conservation. In each of the last three years, Xerces Society staff were quoted or our work was mentioned in thousands of media articles that reached over one billion people worldwide.

For general information about our work, please see our blog, publications, and other information on our website. Follow us on social media for the latest updates, as well.

We’re happy to give media interviews. Please direct all inquiries to Matthew Shepherd, Director of Communications & Outreach: (503) 807-1577, [email protected].

April, 20 2016
Last night, with a vote of 4 to 1, the City Council of Milwaukie, Oregon, passed a resolution to help protect and restore bees and other pollinators. The resolution will halt the use of neonicotinoids and other like insecticides on public property within city limits. Clackamas County’s integrated pest management plan will mirror the resolution, meaning the suspension of use will extend beyond city limits.

The latest count of monarch butterflies overwintering in Mexico found that the population which will migrate to the United States rebounded again this year. Monarch numbers increased to 150 million from 42 million last year, according to data collected by the World Wildlife Fund Mexico and announced today. Today’s numbers show a substantial increase from the last two years (the two lowest years on record) but are still far below a number that most scientists consider sustainable. Scientists estimate the population size by counting the number of hectares of trees covered by monarchs, and found that 4.0 hectares were occupied this year. Researchers estimate that there are approximately 37.5 million monarchs per hectare.

Results from a survey of monarch butterfly overwintering sites in California show that there are more monarchs overwintering in the state this year than last. Volunteers with the Xerces Society’s Western Monarch Thanksgiving Count visited 187 sites and tallied a total of 271,924 monarchs. Although more monarchs were counted, the average number of monarchs per site is not significantly different than last year’s count, and this year’s population estimate represents a 39% decline from the long term average. The number of monarchs counted this year is but a fraction of the 1.2 million monarchs recorded in the late 90s.

First reports from monarch overwintering sites in California surveyed during the Xerces Society’s Western Monarch Thanksgiving Count suggest that 2015 may have been a better year for the beleaguered monarch butterfly in the western United States. The overall population size is still far lower than it was in the 1990s, when more than one million butterflies were counted.
November, 04 2015
Data released today show that monarch butterfly populations at overwintering sites in California may be remaining stable. Volunteers with the 2014 Xerces Society Western Monarch Thanksgiving Count visited 185 sites, nearly two dozen more than the previous year, and tallied a total of 234,731 monarchs. This is up from the 211,275 counted in 2013. However, the average number of butterflies per site was slightly down, and the overall increase is likely due to the fact that more sites were surveyed this fall.
