We work to promote the enhancement, growth and careful use of Mt. Lebanon’s green space parks - BIRD PARK, TWIN HILLS AND ROBB HOLLOW - and to foster an appreciation of and respect for the environment.
The Mt. Lebanon Nature Conservancy has many nature-based programs, volunteer work days, a native plant sale and more. To learn about our events, please see our list of events.
Program: Green Reads Book discussion
Tuesday, Oct. 6, at 7-8 p.m.
Mt. Lebanon Public Library, Meeting Room B
Join the Green Reads Book Group to discuss The Way Through the Woods: Overcoming Grief Through Nature by Long Litt Woon. Request the book at the Mt. Lebanon Library Circulation Desk in September.
A month after Woon arrived in Norway from Malaysia as an exchange student, she met Eiolf. They fell in love, married, and settled into their lives together for 32 years. Then Eiolf’s unexpected death at fifty-four left Woon struggling to imagine a life without her partner and anchor. Adrift in grief, she signed up for a beginner’s course on mushrooming — a course the two of them had planned to take together — and found, to her surprise, that the pursuit of mushrooms rekindled her zest for life.
The next Green Reads book discussion will be Nov. 3. The group, co-hosted by the library and Mt. Lebanon Nature Conservancy, focuses on books related to nature, conservation, and environmental action.
Project: Twin Hills Riparian Area Planting
Sunday, Oct. 25, 9-12
Meet at Twin Hills Drive entrance to the park
Throughout 2026, we are improving a riparian zone along the stream in Twin Hills.
Today, we will be planting native trees and shrubs on about 0.3 acre around the lower (zigzag) bridge. This is the area where volunteers cleared away invasive shrubs in September.
Meet at the Twin Hills Drive entrance. Bring a shovel if you have one, and wear tough gloves or borrow some from us. Dress for the weather.
Sign up here! We will contact you if weather affects our plans. You could also sign up for a park clean-up project on Nov. 14.

Annual Meeting Event: Film Screening & Discussion

Mt. Lebanon Public Library, Meeting Room A
Join us for a film screening of “The Extraordinary Caterpillar” as part of our annual event.
We’ll watch and discuss this award-winning documentary about the smallest inhabitants in our gardens, and the important role they play in the ecosystem. The film features amazing images and unique insights from the scientific community. The event will start with a brief review of LeboNature’s eventful year.
After the film, stay for conversation and light refreshments. This is a great time to mingle, meet like-minded people and learn how you can get involved!
EVENT IS FREE AND EVERYONE IS WELCOME. Suitable for adults and young adults. No registration is required.
