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


Green Reads: “Raising Hare”

  • Tuesday, Sept. 1, 7-8 p.m.

  • Mt. Lebanon Public Library, Meeting Room B

Join the Green Reads Book Group for a lively discussion of Raising Hare: A Memoir by Chloe Dalton. Ask at the Mt. Lebanon Library Circulation Desk in August.

Dalton writes of her experience rescuing and raising a baby hare (leveret) during the COVID-19 lockdown in the English countryside. The memoir details the unlikely, years-long relationship that develops as the wild hare becomes a companion, and explores themes of freedom, trust, and the human-animal bond.

Project: Twin Hills Riparian Area Clearing

  • Saturday, Sept. 19, 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 clearing invasive shrubs and vines from about 0.3 acre, so the area will be ready to plant in October.

Meet at the Twin Hills Drive entrance. Bring clippers or loppers if you have them, 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 to help plant trees and shrubs on Oct. 25.

Program: Migratory Bird Day Hike

  • Meet at Beadling Parking Lot, Bird Park

In celebration of Migratory Bird Day, join Mt Lebanon Nature Conservancy Board Member and Ornithologist  Dr. Jim Saracco as we hike through Bird Park looking for birds, especially species migrating through. Learn how you can contribute data to a citizen science project (e-Bird) through the Cornell Lab of Ornithology. Be sure to wear sturdy footwear, dress for the weather and bring a pair of binoculars. If you are interested, you may download Cornell Lab of Ornithology’s free app (Merlin) onto your mobile device and practice using it during the hike. 

We will be meeting at the Beadling Parking Lot to begin our walk. This event is suitable for adults and high school students.

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!
