October 16 at 12 p.m. - Nature at Mac Walking Tour Sign-up here
Join us on a hike through the west end of campus, stopping at focal ecological sites along the way, where you will see views of the creek and ongoing research and conservation. During the hike, our staff are eager to tell you about our restoration efforts.
Please be sure to be prepared for weather conditions, including muddy trails (wear shoes that you won’t mind getting dirty, as well as being comfortable, closed-toe, durable shoes). We also recommend wearing long pants and long socks to keep ticks and poison ivy from coming into contact with your skin. Bring water, sunscreen, and bug spray as needed, as well as sunglasses and a hat. The hike is of easy to moderate difficulty depending on experience, with a few hills, but we will be sure to take lots of breaks!
Hike starts outside the College Crescent entrance to Mary E. Keyes Residence building at 12 p.m.
October 28 & 29 - Waste Audit Sign-up here
Join us for McMaster’s 2025 Waste Audit and help make a measurable impact on campus sustainability! Volunteers will help sort and collect data from waste samples to understand better what’s being thrown away and how we can improve McMaster’s waste diversion rate.
There are three shifts available each day:
- 8 a.m. – 11 a.m.
- 11 a.m. – 2 p.m.
- 2 p.m. – 4 p.m.
Waste audit locations will vary across campus depending on the shift selected. Details will be shared with volunteers prior to their shift.
