"Wander & Wonder" walks take place at Muller Field Station at the south end of Honeoye Lake every Friday from 9:00 a.m. to 10:00 a.m. during FLCC's semesters. Free to attend. No registration required.
Every Friday during FLCC’s semesters, everyone is welcome to Muller Field Station for a Friday morning Wander & Wonder walk. Each week, MFS staff and friends take the same channel trail loop, noting seasonal changes with a fresh perspective of an ever-changing special guest.
The walk begins at 9 a.m. and departs from the Muller Field Station parking lot. We head south along the channel trail, up through old fields, and around back to our main driveway- measuring just under 1 mile. This walk takes 1-1.5 hours, depending on the observations made, both big and small.
No registration needed.
You may have heard of biochar and its many benefits when added to your soil, but just what is it and what are the benefits to using it. Biochar isn’t something new it was developed by pre-Columbian indigenous populations in the Amazon Basin (mainly modern-day Brazil) over 2,500 years ago. Did you know you can make your own biochar at home from different types of biomasses such as woody plant material and even grasses.
Sonnenberg Gardens and Cornell Cooperative Extension are hosting a free workshop on Saturday April 18, 2026 from 10:00 am-12:00 pm. Rain date Sunday April 19, 2026 from 11:00 am-1:00 pm.
The workshop will be held at Sonnenberg Gardens, 250 Gibson St. Canandaigua NY. The instructor is Kathleen Draper who has been involved in the biochar industry for the past 15 years as an educator, researcher, and consultant. Kathleen will be doing a live demonstration on how to make biochar that you can do the same at home and explain just what it is, its many uses and how biochar improves your soil and impacts climate change.
You must register for this event by contacting Cornell Cooperative Extension at 585-394-3977 ext.427 or email Nancy .

We stumbled upon this treasure of plants in 2025 and knew we needed a visit to see the trillium and other spring ephemerals this year. Located between Zurich Bog and Kraai Preserve, you'll find the Sanctuary at Crowfield Farm near 2488 Arcadia Zurich Norris Road. We will have a carpool leave from the Sly Street parking lot in Canandaigua at 9 AM on Saturday, April 25th and will post our CANANDAIGUA BOTANICAL SOCIETY signs at the entrance to the property.
You are sure to be equally delighted in our leaders Carol and Dave Southby of the Burroughs Audubon Nature Club!
The trillium grow along a large west facing hill. Bring your hiking poles if you have them.
