Celebrating PDE’s Pearl Anniversary — 30 Years of Protecting the Delaware Estuary

 

The 2026 Experience the Estuary Celebration brought together hundreds of regional environmental leaders, partners, and supporters for a memorable evening honoring the Partnership for the Delaware Estuary’s Pearl Anniversary and our shared commitment to protecting and restoring the Delaware River and Bay.

Together, we celebrated PDE’s 30th anniversary and three decades of science, collaboration, and community impact. Guests enjoyed delicious food, connected with friends and colleagues, and helped build momentum for the next 30 years of a thriving Delaware Estuary.
