Learn about Invasive Species, Fish Tracking, Night Skies at Crossroads

Visit Crossroads at Big Creek on March 12, 7 pm, for the Wild Ones lecture “Alien Invaders – Not Welcome!” Kari Hagenow – The Nature Conservancy’s Door peninsula land steward and president of the Invasive Plants Association of Wisconsin – will discuss how invasive plant species steal space, water and other resources from our native habitats and create monocultures. 

The Fish Tales lecture series will continue March 19, 7 pm, with “Where Fish Wander in Green Bay: Tracking Movements of Walleye and Whitefish” by Dan Isermann of UW-Stevens Point. He will discuss how acoustic-telemetry technology enables him to track where walleye and lake whitefish fish spawn and move from southern Green Bay to Bay de Noc and even Lake Michigan. 

The Door Peninsula Astronomical Society (DPAS) will host a viewing night March 28, 7 pm. If the sky is clear, DPAS will point the 16-inch telescope at some of the early-spring sky objects, and the images can be seen live on the 80-inch flat screen in the Stonecipher Center. When the sky becomes sufficiently dark, participants may borrow the viewing binoculars and telescopes, and members will be outside to help participants find constellations and planets. If the sky is overcast, programs will be presented in the inflatable planetarium.

The Collins Learning Center, 2041 Michigan St. in Sturgeon Bay, is open weekdays, 10 am – 4 pm; weekends, 1-4 pm; and during scheduled activities.
