Natural Lands Trust (NLT) is a non-profit land conservation organization with headquarters in Media, Pennsylvania, dedicated to the management, protection, and conservation of eastern Pennsylvania and southern New Jersey’s native forests, fields, steams, and wetlands. The organization owns and manages 41 nature preserves—totaling more than 21,000 acres—located in 13 counties in Pennsylvania and New Jersey. Seventeen of the preserves are open to the public for recreational use; the others have limited visitation due to the presence of sensitive ecosystems or limited facilities.
