March 7
1:00 PM - 2:00 PM PT/ 2:00 PM - 3:00 PM MT/ 3:00 - 4:00 PM CT/ 4:00 PM - 5:00 PM ET

Mormon crickets and grasshoppers are an important part of western grassland ecosystems, supporting the food needs of dozens of bird species such as the declining American Kestrel and Western Meadowlark. Yet public lands in the Western United States, especially in Montana, Wyoming, and Oregon, are frequently sprayed with pesticides to kill these important native insects.

Join American Bird Conservancy (ABC) and the Xerces Society for Invertebrate Conservation on March 7th at 2pm MT/4pm ET to find out how this program impacts important bird prey like caterpillars and beetles. ABC's Hardy Kern and Xerces' Sharon Selvaggio will discuss how conserving habitat for beneficial invertebrates, as well as birds and other grasshopper predators, is part of the solution for keeping grasshopper populations manageable.


  • Hardy Kern, Director of Government Relations, Birds and Pesticides Campaign, ABC
  • Sharon Selvaggio, Pesticide Program Specialist, Xerces Society

Sharon assists Xerces staff, partners, and the public to reduce reliance on pesticides and understand pesticide risk to invertebrates. Sharon previously worked at Northwest Center for Alternatives to Pesticides, the U.S. Fish and Wildlife Service, and the U.S. Forest Service, and integrates her focus on pesticides with her experience managing natural areas and agricultural lands. Sharon earned a Master of Science in energy and resources and a Bachelor of Arts in biology, both from the University of California, Berkeley. Sharon spends a lot of time in her vegetable garden, which has an always-buzzing insectary/pollinator patch, and she is a frequent visitor to the Pacific northwest's wildlands for recreation

March 7
4:00 PM - 5:00 PM PT
Cramer Hall 53 - Portland State University
Portland, OR

Portland State University's Department of Environmental Science and Management is presenting a winter seminar series on pollinators. The series continues with Scott Black, executive director of Xerces Society for Invertebrate Conservation. 

Though they are indisputably important, insects and other invertebrates are experiencing a multicontinental crisis evident as reductions in abundance, diversity and biomass. The loss of insect diversity is driven by habitat loss and degradation, pesticide use, climate change, diseases and more. The science is clear: It is impossible to address the loss of biodiversity without addressing climate change, but equally impossible to tackle the full impacts of climate change without working to protect and enhance biodiversity. Scott will discuss how nature-based solutions can address both. 

This event is hosted by the Department of Environmental Science & Management, Portland State University

Join Rich Hatfield, Xerces Senior Endangered Species Conservation Biologist, to take a deep dive into the reproductive females of bumble bees, including cuckoo bumble bees. We'll primarily look at the solitary phase of the lifecycle, including what is known about where and how they hibernate, and what we know about what it takes to establish a nest and how they select a site. We'll likely have as many questions as answers in this webinar, but please join us for an exploration into the lesser known aspects of bumble bee ecology.

This webinar will be recorded and available on our YouTube channel. Closed Captioning will be available during this webinar.

May 15
5:30 PM - 7:30 PM PT
Level Beer 5211 NE 148th Ave
Portland, OR

Join the Xerces Society and the Columbia Slough Watershed Council to talk about providing residential landscapes as habitat for invertebrates. Please join us! 

Populations of many invertebrate species are declining, but home gardeners can play an important role in their conservation as yards are well positioned to provide habitat for these species in residential landscapes. We will talk about why these creatures are important and how to create invertebrate habitat year-round at home. We will also touch on the risks pesticides pose to invertebrates at home and across the broader urban landscape (including urban waterways).
