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: Walk with us at Wingfield Pines!
Saturday, July 12, Time TBD.
Park at the bottom of the entrance drive. The gate will be unlocked for hike participants.

Join board members of the Mt Lebanon Nature Conservancy for a walk along some trails at Wingfield Pines, a natural area in Upper St. Clair owned by Allegheny Land Trust.
We will hike about 1 mile on an easy trail to view mine drainage cleansing pools, Chartiers Creek, wetlands and woodlands. You might spy an American bullfrog from the boardwalk.
Stay tuned for the time of this event, which is still being worked out.
In case of bad weather, we’ll contact all registrants with updated plans.
Twin Hills Trail Work and Stiltgrass Removal
Saturday, July 19, 9 a.m.- 12 p.m.
Meet at the Twin Hills Drive entrance to the park.

Please join our efforts to improve Twin Hills Park. We need to fix up some trails and pull invasive stiltgrass before it goes to seed and becomes even more of a problem.
Please wear long pants and sleeves, and actual shoes, not flipflops for tick and poison ivy protection. Bring water, gloves, loppers, clippers and/or saws.
All activities are weather permitting.
You can park on Northridge if the Twin Hills Drive dead-end is filled up.

School in the Park 2025 recap
Thanks to the seven elementary schools, third grade teachers, chaperones and community volunteers and organizers Sarah Levinthal and Alexis Smith for carrying out another successful season of School in the Park. This is an interactive nature discovery program for Mt. Lebanon’s 3rd grade students held each spring in Bird Park.
Mt. Lebanon Nature Conservancy began this program in 1984, in collaboration with Mt. Lebanon School District. The program’s activities support the school district’s third grade science curriculum.
During their visit to the park, students investigate the Field Edge, Forest and Stream habitats, and learn about adaptations of Birds and Invertebrates. School in the Park is staffed entirely by volunteer instructors from the Mt. Lebanon Nature Conservancy, the community, and high school students. Most of these high school volunteers are graduates of the School in the Park Program themselves!
Thank you!
