ACTION ALERT: Support ecological management of the most valuable public resource for our coastal ecosystem and economy

The Atlantic States Marine Fisheries Commission is accepting public comment on the establishment of ecological management of Atlantic menhaden (Brevoortia tyrannus), which is a keystone species. Basically, a keystone species is one that plays a large role in the ecosystem where it lives. If a keystone species is lost then the ecosystem would dramatically change or cease to function, causing widespread effects to other species that benefit. In New Jersey, ospreys have largely benefited from a healthy menhaden population as we’ve had relatively high reproductive rates (more than double what’s needed to sustain population) over the past decade. From 2006 to 2016, the population has grown by 30% and above the pre-DDT, historic milestone of over 500 nesting pairs. Around 82% of the state population of ospreys nests along the Atlantic Coast and we observe menhaden at a huge number of nests during our mid-summer surveys. If menhaden numbers drop, then we will likely see osprey numbers follow suite, as reproductive rates will decline, as they are in the Chesapeake Bay.

Osprey 78/D: A Second Chance

“Chump” is rescued, rehabbed, and released

Chump, what are you doing down there? Photo by Northside Jim.

On Sunday, August 30 I woke and checked my email early that morning. I had an urgent message from Deb Traster, who lives adjacent to the Long Beach Island Foundation of the Arts & Sciences (LBIF). She said that something was not right with one of the young ospreys that fledged from a nearby nesting platform where I banded three nestlings with red bands on July 7. One was on the ground and could not take off. Fearing the worst (entanglement), she checked it out and sought help. After getting in touch with me, I reached out to my buddy, Northside Jim to see if he could get there that morning. (more…)

Part I: The Importance of Grassland Habitat

By Meghan Kolk, Wildlife Biologist

In this blog series, my goal is to examine the importance of grassland habitat in our state, introduce CWF’s new habitat restoration project, and highlight many of the species of grassland birds our project aims to benefit. So, first I’ll start off with a little background information about grasslands and why we need to preserve, restore and create more of this critical habitat. (more…)

Citizen Scientists Needed to help collect data on nesting ospreys

by Ben Wurst, Habitat Program Manager

Two young ospreys and an adult on a nest in Ocean County.

This year we are hoping to get a better estimate of the size and health of the osprey population in New Jersey. Up from only 50 pairs in the early 1970s to an estimated 600+ pairs today. Ospreys are an indicator species and as top tier predators, they show the effects of contaminants in the environment before many other long lived species. They are our new age “canary in the coal mine” so keeping tabs on the health of their population is key to assessing the health of our estuarine and marine ecosystems. (more…)

Shorebirds, eagles, horseshoe crabs and more….

May is a great time to visit the Delaware Bay beaches. The horseshoe crabs are spawning and shorebirds are feeding on the eggs. Please respect the beach closures, so that the shorebirds can feed undisturbed.
