Events
There are hundreds of environmentally-related events every year in Indiana, and for now at least I lack the time to find and list that many. So, the focus of this page is on events that are perhaps of interest across the state, rather than local events. Having said that, I'll include local stuff if I have time. Know of something that should be included? PLEASE let me know. Thanks!

2026 Phenology Hike
Clegg Memorial Garden, Lafayette
5:00 pm
Join NICHES Land Trust at Clegg Memorial Garden for their Phenology Hike series to track seasonal changes in plants throughout the 2026 growing season. Phenology is the study of seasonal patterns in nature, observing and tracking events like when plants bloom, leaves appear, or fruit ripens, and how these events change over time. These guided hikes are designed to help participants practice native plant identification, learn to use field guides, and keep track of their observations. You are welcome to bring your own guides, and some will be available to borrow through the Clegg Library. No prior plant identification knowledge is required to participate! Please dress for the weather and consider bringing study hiking shoes, water, and a snack.
