In 2010, TINS initiated an annual butterfly count, centered on Osgood Swamp and encompassing much of the southern Tahoe basin (view map of count circle). The goals of the counts are threefold: to (1) gather data to monitor butterfly populations, (2) give butterfly enthusiasts a chance to socialize and have fun, and (3) to increase public awareness and interest in butterflies and butterfly conservation needs. Experts from around the state have joined the Tahoe count, and more experienced butterfly enthusiasts will be assigned to cover various portions of the count circle, either solo or in small teams. All are welcome, however. We primarily use the count to generate interest in butterflies, and beginners can have a great time learning the basics.

Anyone interested in participating, please contact Will Richardson to be kept up to date on the latest information regarding the 2022 count.
