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



Check out an article in April’s Mt. Lebanon Magazine to see how root structures match growing conditions.

NATIVE PLANT SALE 2025

  • Be ready to snap up your favorites after 8 a.m.!

  • The sale offers 18 native species (subject to supplier availability). They are in the form of “landscape plugs,” which are young plants with highly developed root systems.

  • Plants are sold in strips of either 4 or 5 plugs, depending on the species.

  • Strips cost $25-$27.50, depending on the plant and how much it costs us wholesale. A few will be available as single plants.

  • Plant pickup will be May 3, 10 a.m. - 1 p.m. at Sunnyhill Unitarian Church, 1240 Washington Road. There will also be an in-person sale on May 3, with the same plants on offer as via the online sale.


PROGRAM: Spring wildflower hike

Join a spring hike through Boyce Mayview Park to search for spring ephemerals. This is an excellent opportunity to explore a green space in neighboring Upper St Clair. Boyce Mayview is known for mayapples, spring beauty, trillium, and more spring wildflowers that are not to be missed!


This video pans around the area where volunteers will be planting on April 19.

PROJECT: Spring planting in Bird Park

  • Saturday, April 19, 9 a.m.- 12 p.m.

  • Meet at the Beadling Parking lot at Bird Park

  • Sign up HERE!

This will be so much fun! Join in a park improvement project to plant native trees and shrubs in an area of the park (uphill from the soccer field) that a volunteer crew cleared in March. We’ll also be installing tree tubes or fencing to protect the new plants from browsing deer.


Thank you!

~ 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.
