Feeling the heat of summer yet-your local Algific Slopes are loving it! Algific(cold air)Slopes are a unique micro-climate found in the Driftless area in Northeast Iowa. These sensitive ecosystems are only found in a few places of the world, Iowa being one of them. Algific slopes formed when warm summer air is drawn into sinkholes and is cooled as it flows over iced blocks of limestone. The cool air then escapes through the vents on the sides of the Algific Talus slope. The Fish & Wildlife Service diagram below shows the process in-depth.
Algific Slopes contain a large number of diverse species not typically found in Iowa. Some of these species include: Canada Yew, Balsam Fir Tree, Golden Saxifrage. Also the Federally Endangered Iowa Pleistocene Snail and Federally Threatened Northern Monkshood plant-both of these species can only survive on Algific Slopes. The other day the naturalists at Osborne had the opportunitity to view the Northern Monkshood for the first time. The picture truly can do no justice to the beauty and sensitive requirements of this fragile plant we are blessed to have in our county.
For more information on Algific Slopes in Northeast Iowa you contact Osborne Nature Center or the U.S. Fish & Wildlife Service who manages the Driftless Area National Wildlife Refuge.
