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.

Our 2026 Spotlight Project
Twin Hills Park
Riparian Area
This year we plan to rehabilitate the stream area “between the big bridges” in Twin Hills!
Please join us as we improve the site’s ecology by removing invasive plants in March and September, and planting native species in April, May and October.
Project: Twin Hills riparian area planting
Saturday, April 18, 9-12
Twin Hills Park, Chatham Park Drive entrance ( 40°23'52.2"N 80°03'24.8"W )
In 2026, Mt. Lebanon Nature Conservancy volunteers will improve the riparian area along Twin Hills Park’s stream.
We will be planting native trees, shrubs and perennials in the 0.3-acre area where we removed invasives in March. We also will be enclosing each new plant in deer-protection fencing.
If at all possible, please bring a gallon or two of water to give the new plants a drink. Bring a shovel and gloves if you have them, or borrow some from us. Dress for the weather.
Sign up here. You’ll receive notifications if weather affects our plans.

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.
