July 27 – Scarabs Monthly Meeting: Effect of Fire on Butterflies, by Rich Hatfield, Xerces Society

Burke Museum

UW, 17th Ave NE and NE 45th St, Seattle, WA

7:00 pm July 27

Scarabs meet in the Burke Museum classroom, in the rear of the museum building, NW corner of the University of Washington Campus in Seattle; enter from the museum loading dock.

Fire can be a beneficial management tool for maintaining healthy habitats. However, it must be used with caution to avoid eliminating the very species that it is meant to benefit. Controlled burns are often used by land managers to remove invasive weeds and maintain natural plant communities. How these burns affect butterflies and other insects is less well understood. A recent study by the Xerces Society examined the effect of controlled burning on a rare Pacific Northwest butterfly, the mardon skipper (Polites mardon).”Controlled” burning (often not as well controlled as the managers hoped) also affects many other invertebrates, including spiders!

Rich Hatfield, a conservation biologist at the Xerces Society in Portland, specializes in pollinators and will be in town to lead a bumble bee workshop. Rich will present the results of this study in the larger context of the impact of controlled burns on butterflies and other pollinators.

As always, all are welcome at our meetings, whether members or not. (Dues paying members get a newsletter by postal mail).
