Early Thanksgiving Counts Show a Critically Low Monarch Population in California
Published on November 29, 2018
The California overwintering population has been reduced to less than 0.5% of its historical size, and has declined by 86% compared to 2017. While western monarchs are facing unprecedented challenges right now, there is still hope that we can recover the population if we work quickly, strategically, and together.

New Research Confirms Decline in Western Freshwater Mussels
Published on October 27, 2017
When we talk about native freshwater mussels (not the invasive zebra mussels you’ve heard so much about), we often start by mentioning how obscure they are, that they look like rocks and live in places where they go largely unseen. It’s true that freshwater mussels aren’t as showy as butterflies, or as celebrated as bees, Read more …
Expanding Our Understanding of Pesticide Impacts on Invertebrates
Published on April 28, 2017
In an effort to keep up with the constantly expanding information available about pesticides and their impacts on pollinators and other invertebrates, the Xerces Society created the Impacts of Pesticides on Invertebrates database (pesticideimpacts.org). The database is a collection of summaries of recent research articles; it does not include the articles themselves, but does provide Read more …
Obligate Mutualism Blooms in the Desert
Published on April 18, 2017
Tikaboo Valley, Nevada. Home of the Extraterrestrial Highway, the infamous black mailbox, UFO seekers, cattle ranchers, and desert wanderers.
