Restoring floodplains and protecting urban communities may not sound like a typical workday for the biologists of Conserve Wildlife Foundation of NJ (CWFNJ). However, multiple staff and board members of CWFNJ were present at the annual Blue Acres Floodplain Restoration Fall Planting and Clean-up Day on October 27^th, clearing weeds, trash and planting new trees and shrubs at the Tremley Point restoration site in Linden. Blue Acres, a program created by the New Jersey Department of Environmental Protection, helps residents in low-lying areas that are subject to repeated flooding by buying out their properties and aiding in homeowner relocation. The acquired properties eventually become buffer zones, such as floodplains, that protect surrounding communities from the impact of storms and rising sea levels by acting as natural floodwater storage. The land purchased through the Blue Acres program may also be restored into functional wetlands, habitat for wildlife and open green space for the community to enjoy. Blue Acres not only provides disaster relief for residents whose homes have been destroyed or damaged by flooding and surges caused by large storms, but also contributes to the NJ Climate Change Resilience Strategy by proactively creating wetlands and floodplains to lessen the severity of future flood events.

When looking at the expansive mudflats along the marshes of the Delaware Bay, it is hard to imagine that the area was once densely vegetated and home to a variety of bird species. This spring, CWF began work on a new marsh restoration project funded by the National Fish and Wildlife Foundation and led by Ducks Unlimited and the U.S. Fish and Wildlife Service (USFWS). CWF was contracted to assist with biological monitoring at sites targeted for marsh restoration along New Jersey’s side of the Delaware Bay. Restoration efforts for our sites are being directed toward mudflats that exist due to significant physical alterations made to the marsh in the past. The story of how these mudflats came to be lies in the area’s history and roots in salt hay farming.

As early as 1675, settlers arriving on the Delaware Bay built dikes in salt marshes to protect land from saltwater inflow and create an environment more conducive to salt hay farming and development. One of the most important types of salt hay harvested along the Delaware Bay was Spartina patens, a crop that was widely used as bedding and feed for livestock due to its high nutritional value. By the mid-1800s, at least 14,000 acres of marsh were impounded in Salem County alone with comparable areas altered in both Cumberland and Cape May counties (Cook, 1870). Impoundments restricted tidal flow within the marsh, which stopped the natural process of marsh accretion in which sediment is consistently added to the marsh to increase its elevation. Additionally, drier conditions exposed marsh soil to too much air, resulting in the breakdown of soil and further loss of elevation.

When the Barnegat Light habitat restoration was completed to benefit piping plovers several winters ago, the partners anticipated it would need periodic maintenance to keep it in optimal condition. As it has turned out, the inlet beach site has needed more frequent attention, an annual winter “touch-up” to prep the site for the nesting season. With this in mind, earlier this month, Todd Pover, CWF Senior Wildlife Biologist was on-site for nearly a week to oversee the habitat work. 

The maintenance this winter primarily focused on the two foraging ponds, as those features have proved critical to the success of the plovers utilizing the site. Thick vegetation was mechanically removed from about three-quarters of the perimeter of the large pond. Excessive vegetation can obstruct piping plovers, especially their chicks, from using the pond’s edge to feed. The heavy vegetation can also provide cover for predators. Meanwhile, the smaller pond was filled in with sand due to late fall/early winter storms and tidal surge. Although the small pond has needed to be “refreshed” each winter, this was the first time it had to be entirely re-dug. Experience has shown that having two ponds present at the site – giving plovers alternative feeding options if one pond is not accessible or as productive during a portion of the season – has been a key element in boosting productivity, especially as more plovers chose the site to nest. In addition to the pond work, some vegetation thinning or removal was also completed to enhance the suitability of the nesting areas as plovers prefer sparsely vegetated areas to lay their eggs.

The results are in! It wasn’t a great year for upland sandpipers at the McGuire Airfield. Numbers of breeding pairs at this location have decreased to an estimated two pairs. Numbers can be variable from year to year so there is still hope for better news in 2023.

Upland sandpipers typically require a minimum of 100 acres for breeding habitat and so large expanses of open, grassy land is a high priority. Over the past five years, long term efforts have been ongoing to complete a large-scale grassland restoration at the McGuire Airfield. So far, roughly 500 acres have been converted to native warm season grasses with another 100 acres to be completed by next spring. Our goal is to help create and maintain grassland bird nesting habitat for Upland sandpipers and other species.

Hurricane Ida. Hurricane Irene. Superstorm Sandy. These weather events represent three of the four most devasting storms recorded in New Jersey history. Though data dates back 218 years, all 3 have occurred within the past 11, substantiating concerns over the effect of climate change on tropical cyclone severity. Therefore, taking measures to safeguard communities from devastating floodwaters is more important now than it ever has been. But who said helping people can’t, in turn, help wildlife?

As the coordinator for CWF’s Amphibian Crossing Project, I think it’s safe to say I spend more time than the average person hoping for rain to pop up in springtime forecasts. April 22, however, is always an exception. What could be better than warm and sunny conditions to inspire folks to get outside and celebrate Earth Day by giving back to the planet that gives us, well, everything? Mother Nature certainly came through with the weather last week, handing us one of the most glorious days of the season thus far, while the Elizabeth Mayor Chris Bollwage, Union County Board of County Commissioners, Groundwork Elizabeth, and their partners offered a destination for all the aspiring wildlife warriors: Phil Rizzuto Park.

Restoring valuable wildlife habitat in northern new jersey

By MacKenzie Hall, Private Lands Biologist

Last week, a park in Hillsborough Township got a makeover.  Following “a shave and a haircut,” more than seven acres of fallow farmland were planted with 1,500 native trees and shrubs.

This afforestation is the latest partnership between Hillsborough and the Conserve Wildlife Foundation to improve wildlife habitat on township-owned lands.  The park (on Wertsville Road between Montgomery & Long Hill Rds) sits on the northern edge of the Sourland Mountains, which hold significant values to forest wildlife, migratory songbirds, human residents and recreationists.  Our project will extend this forest cover and all of its benefits.

We selected 25 different native tree & shrub species with a variety of things in mind…for example:

• Red, white, black, and chestnut oaks will produce acorns, a great food source for many animals;
• White pines grow densely to shelter wildlife in winter;
• Hackberry and sassafras are larval food sources for certain types of butterflies;
• Tulip poplars grow quickly and are loved by bees;
• Shagbark hickories are important bat roosts in summer;
• Elderberry, bayberry, and dogwoods produce fruit to fuel migrating songbirds as well as animals who winter here.

While the trees are in the ground, this project is still “in progress.”  The next step is to install temporary fencing to protect the saplings from deer browse.  We’ll also have to fight the invasive plants – like autumn olive and multiflora rose – that grew so heartily at the site before. And lastly, we still have 150 trees and shrubs to plant at the neighboring Otto’s Farm Park.  Please contact me (908-782-4614 x 104) if you want to help!

A huge “THANKS!” goes out to Conservation Resources, Inc. for funding a large part of this restoration, to the US Fish and Wildlife Service’s NJ Partners for Fish and Wildlife program for donating 1,000 of the trees and shrubs, to the D&R Greenway Land Trust nursery and Pinelands Nursery for their beautiful plant products, to Hillsborough Township for investing in their local wildlife, and to the 20 volunteers who helped with the tree planting.
