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.

MLK Day of Service: Native Plant Seed Sowing

  • Monday, Jan. 18, 2027, 9-noon

  • Mt. Lebanon High School

Mt. Lebanon Nature Conservancy is leading an interactive workshop on winter seed sowing as part of Martin Luther King Jr. Day of Service sponsored by Mt. Lebanon’s Community Engagement Advisory Board.

You can help improve our community’s ecology and resilience by growing native plants that best serve native pollinators, birds and critters. At this workshop, you’ll sow seeds that will germinate when the weather warms. You’ll leave the workshop with a recycled container of sown native seeds. Your plants will be ready to go into the ground in the spring, and you can plant them in your own garden or join the Conservancy to plant the seedlings in our parks. Seeds, soil and containers provided.

The workshop will take place at Mt. Lebanon High School. Sign up via the municipality’s interest form, coming soon.


Project: Twin Hills Winterization Project

  • Saturday, Nov. 14, 10-1. Note the 10 a.m. start!

  • Meet at Chatham Park Drive (Carriage Park Apartments) entrance to the park, off Green Tree Road

We’ll be working mainly in the western part of the park today. We’ll switch out tree-tubes and install cages, and winterize the stairs by replenishing the gravel.

Bring a shovel or steel rake 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.

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!
