Lower Rahway River, New Jersey
The lower Rahway River is the longest, unbridged river mouth ecosystem in the northern half of New Jersey. This riparian corridor is pivotal to hundreds of thousands of resident and migrating insects, fish and birds twice a year, and therefore has regional importance. Tidal marsh areas are ecologically and economically important since the bioavailability of nutrients is 300% higher than terrestrial biomes.
Common to rare resident species are clinging to existence in this area, but the short-sighted continue to propose and implement disruptive roads, fill projects or development.
In 2011, NBP with its close partner Rahway River Watershed Association (RRWA), applied for and received seed monies to purchase some lands along the lower river mouth. NBP needs interested citizens to assist us in these important efforts. Please contact us below if you may be able to help.
Although this valuable open space is integral to all local and regional greenway plans that espouse healthy, sustainable, recreational development, it is not well understood or appreciated as a unique, sustainable economic and recreational asset by various politicians and governmental entities. Naturally we need to do a better job of getting the message out.
Also look at the various other articles about the terrapins and other animals of the lower Rahway River in the Journal, River of Biodiversity:

Diamondback Terrapin Study, NJ
Diamondback Terrapins are clinging to existence on the lower Rahway River in NJ. Please see below for exciting ways you can help the terrapins.
The Rahway River is the longest unbridged, river mouth ecosystem in the northern half of NJ. Several years ago our scientists observed the ornately patterned terrapins in the river’s marshes. The turtles are wary which may be related to past, intense hunting pressure for the food markets. The word terrapin is an alteration of torope, from the Virginia Algonquian language and the terrapin was a sought after delicacy by various peoples.
From 2008 to 2015 we have organized surveys that concurrently visit all the feeder creeks and the main channel of the lower river to assess the ecology, population and spatial distribution of the turtles. Data collected indicates that although food is plentiful and water quality has improved over the last decades there are few hatch year or juvenile turtles in the area. Only a few, large, aging females and several males have been observed.
Here is a link to one story on our terrapin studies; look for other articles at the Journal, River of Biodiversity:
Because of the intense development, including warehouses, railroads, highways and fill events that continue to encroach on the river and its supporting marshes and uplands, the nesting areas have been reduced. The terrapins’ reproductive ability to sustain the population has been permanently damaged and a species that has been here for tens of thousands of years is threatened on the river.
We are looking for schools, colleges, municipalities, companies, individuals and donators to assist in this project by contacting us for one of the following project needs:
Science-citizen surveyors to visit the river in small water craft.
Donations of boat or money to assist the study and implement the solutions.
Be ready to send support letters for actions as needed.
Please contact us if you would like to assist us and learn more.
In a small section of the 42,000 acre Joint Base the insect, herptile and avian grassland community is exceptional. NBP, as a Department of Defense approved biological contractor performed extensive formal surveying of breeding birds while leading various biodiversity-centric field trips for the public. Check our field trip section to get on our trip waiting list or see if we have a trip scheduled.
Avidiversity Studies in NJ
Studying the most diverse taxon of vertebrates in the Eastern US, birds, provides broad ecological data and often insight into which niches and habitats are being degraded or lost. NBP, stakeholders, scientists and our volunteers have carefully reviewed contemporary location data for high avidiversity and exact species present, and converted this into action by proposing specific areas for preservation efforts.

Biodiversity Studies in Suburban and Urban Habitats
Union, Bergen, and Hudson Counties in NJ and other metropolitan areas are heavily developed and populated. By studying and observing altered habitats and impacts on flora and fauna, we can develop corollaries to what spreading urbanization will do and recommend preemptive actions. The areas’ open spaces are inundated with invasive plant species and a significant portion of our plant, invertebrate and vertebrate animal diversity has been lost.
This reduces the quality of life for citizens and lessens the number of children that develop science skills since they have diminished and fewer experiences with nature. Research has shown that outdoor recreation helps children manage stress and increase coping ability. Natural areas stimulate children’s imaginations and foster creativity. Damaged natural communities are detrimental to human ecology and indirectly to local economies as we have less home grown scientists to supply the technical work force which helps drive innovation and economic productivity.
Regardless, suburban and urban habitats show some resilience and recuperative abilities; they can retain recreational, educational, ecological and economic value if action is taken. Please read about our various projects below and at this site and contact us if you would like to join NBP in addressing some pragmatic needs. NBP has completed or designed the following projects/studies plus more not listed:
We reviewed the results of several Union County, NJ Bioblitzes and documented the reduction of insect and bird biodiversity potentially caused by the destruction of forest understory due to white-tailed deer over population, habitat fragmentation and invasive plants.
The results were summarized in a presentation for the State of Biodiversity in the Rahway River Watershed conference.
This presentation or a custom version may be able to fulfill the program or presentation needs of your conference, group, class or meeting.
In 2011, NBP with its close partner Rahway River Watershed Association (RRWA), applied for and received seed monies to purchase some lands along the lower Rahway River mouth. NBP needs interested citizens to assist us in these important land preservation efforts. Please contact us if you may be able to help.
Recorded in Metropolitan Area but Extinctions are Increasing – In the last decade we examined the avidiversity of Union County, NJ with the Rahway River Watershed Association (RRWA). We carefully surveyed open spaces, parks, rivers and the Arthur Kill by foot, boat and canoe and located some of the key breeding bird and migratory stopover areas in the county. Collectively these areas have ecotourism potential and prove that urban areas are important regional, refueling areas for Neotropical migrants. Increasing open space acreage and quality of habitat is difficult but needed to preserve local biodiversity and insure that migrants can survive their passage through our area. Keeping local habitats intact and healthy is important in staving off local, regional and nation-wide extinctions.

is a Problem in Developed Areas – Plastics concentrate in our wetlands, rivers, lakes and beaches; this litter draws the attention of many foraging animals decreasing their feeding efficiency; often it is ingested leading to sickness and sometimes death.
The problem has multiple causes such as the lack of a “bottle bill” in NJ, coupled with minimal enforcement of litter laws and ignorant litterers.
NBP does not believe that these yearly, organized cleanups that are common can even partially solve the problem. Treating the symptom, litter everywhere, is not the answer. Incentivizing and monetizing a solution when the plastic is still in someone’s hand via a “bottle bill” along with enforcement would reduce the litter.
Citizens have a finite amount of time they can volunteer to good causes. Using this valuable goodwill for yearly cleanups leaves other important initiatives understaffed. It would be more efficient to have these precious hours used towards a real solution rather than as a crew of lifetime, unpaid garbage collectors. The volunteers should be used to demand and lobby for a cleanup bill. After its passage our citizens’ goodwill can be utilized for more valuable initiatives like habitat restoration, invasive control, nest box erection, citizen science, etc.
An example of the failure of cleanups occurred in 2010. There was a tremendous concentrating of litter on one side of the Lower Rahway River after a Northeaster. NBP, RRWA, Kinder-Morgan Inc. and PA Associates applied significant manpower and materials to remove several dumpsters of recyclable litter.
If you are interested in assisting NBP in addressing non-point pollution, litter or a bottle bill in NJ please contact us.
Local extinctions, called extirpations, if not addressed can eventually lead to county, state or even complete, range-wide extinctions. NBP has studied fauna in several NJ counties and we are preparing Extinct and Endangered species lists for various areas. We feel these lists will bring some attention to the neglect of our open space and natural heritage. It may also serve to educate elected officials and government departments that these resources are valuable and once lost they cannot be easily restored.
Extinctions hurt suburban and urban areas by lowering our children’s exposure to the natural sciences, damaging our quality of life and lessening the interest and recreational value of these areas.
If you would like to assist NBP in addressing these issues or like assistance in developing and instituting plans to study your local natural assets please contact us.
A compilation of endangered and extinct species of NJ areas based on NBP fieldwork was begun in a presentation for the State of Biodiversity in the Rahway River Watershed conference.
