What are invasive species and why should we care? Freya Berntson, MNRS of NE Indiana Native Plant Society will lead us on an invasive species hike that will allow you to examine first-hand the invasive species we encounter at Eagle Marsh. This training will sharpen our abilities to identify species in the field and differentiate them from possible look-a-likes. Please dress for the weather and bring a water bottle! The barn is not air conditioned, so it can be warm inside. For the hike, wear sturdy shoes and plan to be in full sun the majority of the time. Sunscreen, insect repellent, and hats are highly recommended.
