Thanks to this years crew (my wife Jen, Jon Nikkila, Jen Corman, Teresa Bammerlin, Chris Helzer, and the two Conservancy fellows Sarah Lueder and Kate Nootenboom) the 36 species found was the best species total since 1999. This years count is barely over and I’m already looking forward to next years!
