The Sourland Conservancy presents: Talk of the Sourlands 
The Sourland Conservancy will continue to host our annual education series this fall. Previously held at the Hopewell Train Station, we have decided to take the program on the road this year. Taking our show “on the road” will help us reach more people all around the Sourlands. Talks will take place at the Titusville Presbyterian Church and Duke Farms, among other places throughout the Sourland Region. We have some exciting speakers lined up, including local artists, native tree and birds of prey experts, the African-American connection to our lands, and more!

You can find our upcoming talks and registration links below!

Just a Walk: Otto’s Farm Park

August 23, 2023, at 6:00 PM

Join us for a casual walk at the Otto’s Farm Park Preserve to explore a new path, or rediscover a trail with us. As a group, we will take a relaxing walk in the woods to admire the unique flora and fauna of the Sourlands, breathe in the fresh air, and enjoy the relaxing sights and sounds of a lovely public preserve, as well as each other’s company!
This hiking series is free, but participants are required to register and sign a waiver to attend. Donations are appreciated.
Fall Tree Sale & Plant Swap

October 8, 2023 at Duke Farms Market
October 14, 2023 at the Sourland Conservancy office

Over one million trees in our beautiful Sourland forest will die within the next few years. That’s twenty percent of all trees – in our gorgeous public parks and preserves, in our yard, and probably in yours. One of the best ways to help the Sourlands is by transitioning your mowed lawn to a beautiful native garden. Planting native trees, shrubs, and flowers in your yard will help you save time, money, and the planet!

This year we will be offering a “Biodiversity Kit & Bed Design” sale to help you transform your lawn into that beautiful native garden of your dreams. Stay tuned to learn more!
