that few people were aware of the critical services the marsh provided through protection from storm surges and flooding. Mills decided to do something about it. He had a vision: undisturbed salt marsh acting as a buffer and a nursery, sustaining the life within and around it, and a world-class organization dedicated to learning about it to ensure its conservation and to educating people about the importance of protecting it. For the past 50 years, The Wetlands Institute has embraced Mill’s vision and worked to address the challenges affecting the health and well-being of these marshes and the wildlife that depend on them. Our roots trace back to these early days, and the uninterrupted work that has been done here is incredibly powerful. As scientists, our ability to document change relies on detailed records of conditions in the past. The Wetlands Institute, thanks to the tireless work of so many before us, is extremely well-positioned to take on a leadership role
studying, preserving, and conserving these marshes and coastal ecosystems now and well into the future. Now more than ever, the threats to these marshes are acute. The onslaught of rapidly rising sea is at the forefront of issues affecting the entire back-bay system, our beaches, and our island communities. There is no question the change is already here, and critical questions emerge about how the role of wetlands is changing as a life-support system for fisheries, migratory birds, and storm protection. What does it mean for their future? For our future? If we consider what measured sea level looks like, the best records come from nearby Atlantic City where sea level has been rising at a rate of 0.16 inches per year, which may not sound like a lot – but that is equivalent to 1.34 feet of rise in the last 100 years. If it’s helpful to think about what that actually means for the marshes, below is a graph that shows the actual water level measured in the marsh at The Wetlands Institute as part of a detailed

s our year of celebrations for the 50 anniversary of The Wetlands Institute comes to a close, it’s fitting to look forward to the next 50 years. Throughout the year we have reflected upon the remarkable legacy of research, conservation, education, and stewardship that underpins the impact of The Wetlands Institute in our community and beyond. It’s a history I am proud to be a part of, but even more so, it’s the opportunity to lead our 2020 vision for the future that I am so keen to tackle. Fifty years ago, Herbert Mills, founding director of The Wetlands Institute, saw the future. If left unchecked, rampant development would consume the vast acreage of salt marsh stretching the length of South Jersey’s Atlantic coast. He knew that the loss of such an invaluable resource would be catastrophic for the incredible network of life that depends on the marshes for food and shelter, as well as the coastal communities that benefit from the marshes for recreation and aesthetic value. He also knew th
