Healthy Trees, Healthy Streams: Managing Waterways for a Resilient Future

Associate Director, Land Stewardship and Ecology Lea Johnson, Ph.D.

Conservatory Ballroom

A watershed is more than just a geographic area—it is a vital, interconnected community of land, water, and life. At Longwood, we understand that all water has value, from the moment it falls as rain or snow to the second it leaves our property and begins its journey into the Delaware Bay. Through mindful ecological research and active stewardship, we preserve and restore riparian buffers of native trees and shrubs, safeguarding the nearly 5 miles of streams that intersect on our property from pollutants, erosion, and elevated water temperature. 

Join our Associate Director of Land Stewardship and Ecology Lea Johnson, Ph.D. and learn more about our water stewardship story and the powerful connection between mindful land management and a thriving natural world.
