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: The Weedy Garden book and activities
Saturday, Sept. 26, 10-11 a.m.
Mt. Lebanon Public Library
Ever wonder what bugs and birds see in our gardens?
Join the Mt. Lebanon Public Library and the Mt. Lebanon Nature Conservancy for story time and activities that relate to the natural spaces around us! We will be reading “The Weedy Garden” by bestselling author Margeret Renkl, exploring outdoors, and getting our hands dirty while creating some take-home projects. Please dress to go outside!
Suitable for anyone at a preschool or early elementary school developmental stage, accompanied by an adult. No RSVP needed!
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.
Our 2026 Spotlight Project
Twin Hills Park
Riparian Area
This year we are rehabilitating the stream area “between the big bridges” in Twin Hills!
Please join us as we improve the site’s ecology by removing invasive plants. Join us for phase 2 in September and October!
How you can help Mt. Lebanon Nature Conservancy
Click on the “donate” button to make a contribution online. Sustaining donations (posted monthly to your credit card) help us the most because they even out the cash flow of our small non-profit organization.
Send a check donation, made out to “Mt. Lebanon Nature Conservancy,” to: P.O. Box 14901, Pittsburgh, PA 15243. Checks minimize the fees we pay for online processing.
We also highly value the time that volunteers give through the year. Hundreds of people join in to help weed, clip, haul or plant. We welcome other volunteer help, such as working with us to develop new programs; staffing booths at events like Mt. Lebanon’s Earth Day; doing some printing or photocopying; or contributing photographs that we can post to social media or our website.
Thank you!
