The Nature Conservancy was honored to welcome Commissioner Potosnak and the New Jersey Department of Environmental Protection team into the field to see firsthand how tidal marsh restoration is helping strengthen New Jersey's coast.

This work demonstrates how investing in nature can strengthen resilience, safeguard coastal marshes and help communities adapt to a changing climate. By restoring and elevating vulnerable salt marshes, we can create healthier habitat for wildlife, buffer coastal communities from storms and flooding, and support landscapes that are essential to our state's economy and quality of life.

We appreciated the opportunity to discuss both the promise and the challenges of scaling marsh restoration efforts across the state. Thank you to Commissioner Potosnak and the NJDEP team for their continued leadership and collaboration. We look forward to advancing this critical work together. 🌱

Do you want to see fall migration in action? Now is the time to plan a trip to TNC's South Cape May Meadows preserve.

Our land stewards shared this awesome footage of thousands of tree swallows at the preserve. Each year, beginning in late summer and typically continuing through October, tree swallows fill South Cape May Meadows as they prepare for their long migration south.

Tree swallows are very social birds and during migration form enormous flocks numbering in the hundreds of thousands of birds, which have been known to darken the skies of Cape May in the fall. They supplement their insect diet with berries and can be seen landing by the masses on bayberry trees at our South Cape May Meadows Preserve.

Since 2023, The Nature Conservancy and our partners from the Newark Tree Canopy Initiative have been planting trees across the city as part of a larger effort to expand Newark's canopy cover. 🌳

Last week, TNC staff went into the field to measure the impact of this work. Using thermal cameras, TNC is monitoring temperature differences in areas where trees have been planted compared to locations with little or no tree cover. These images help us visualize how trees reduce heat, cool sidewalks and gathering spaces, and create more comfortable neighborhoods during intense periods of heat. By tracking these temperature changes over time, we're gathering data that demonstrates how planting urban trees can help communities and city residents adapt to rising temperatures, and build a more resilient future.

One less dam is blocking New Jersey's rivers! 🐟🌊

The removal of a small wooden weir dam on Lopatcong Creek in Warren County is having a big impact, reconnecting approximately 13 miles of stream habitat to the Delaware River and improving connectivity for wildlife. The benefits were immediate, with restored stream flow and improved habitat conditions, including the removal of litter from the site.

The Nature Conservancy would like to extend a huge thank you to our partners at Trout Unlimited, whose dedicated volunteers removed the dam by hand with chainsaws, hard work, and determination, and to the private landowner whose support made this project possible.

Footage from the field! 📹

This adorable least tern chick was spotted at the one-mile of protected beach at South Cape May Meadows preserve. Enhanced with nesting enclosures, decoys, bird call boxes and other conservation measures, this site had the highest success rates for least terns in New Jersey in 2023 and 2024, producing about 80 fledglings per nesting season—more than half the state’s annual fledgling totals!

A beautiful moment with a luna moth. 💚

While luna moths aren't considered rare, seeing one can be. Adult luna moths live for only about a week and are active primarily at night, making encounters uncommon. Have you seen any this summer?

Eyes to the skies! Fall is on the horizon as raptor migration begins across New Jersey. This annual movement typically begins in mid-August and lasts through December, with peak activity in September and October. 🦅

Our preserves are raptor-spotting hotspots! Here's a small sampling of the amazing raptors you can see and hear at our preserves, along with the best times to spot them.

A century-long barrier is gone and baby American shad have returned! 🐟

For the first time in more than 100 years, juvenile American shad have been documented above the former Columbia Dam site in the Paulins Kill. The discovery confirms that dam removal restored access to historic spawning habitat and allowed the species to successfully reproduce upstream.

This milestone finding reminds us why long-term restoration and monitoring are so important. Seeing a struggling migratory fish species return, spawn and produce young in habitat that was inaccessible for over 100 years is a powerful example of the many benefits that can result from reconnecting rivers.
