That’s a Wrap for the Pilot Season of a New Collaborative Project with NJDEP Focusing on Pine Barrens Tree Frogs

Friday, August 12th, 2022

CWF intern Connor Zrinko inspects a large tadpole he collected while dipnetting.

At quick glance, Pine Barrens tree frogs (PBTF), with their vivid green backs, deep purple sides, and vibrant yellow thighs, might put folks in mind of Central and South American rainforests. Based on their visage, they could, theoretically, be at home beside red-eyed tree frogs and poison arrow frogs – the poster children of amphibian diversity. They have occupied that spotlight themselves. In fact, in his 1983 Endangered Species series, American pop artist Andy Warhol chose to immortalize the PBTF in silkscreen as the lone representative of herptiles. But these tiny beauties do not favor the tropics. Occurring in three disjunct populations across the eastern United States including the Florida/Alabama panhandle, the Carolinas and, naturally, New Jersey, PBTF are habitat specialists. They reside in seepage bogs where the water is relatively acidic, due to the presiding vegetation. Sadly, as is the case with many animals reliant on very specific landscape features, habitat loss and fragmentation pose a concern for the persistence of this species, which is listed as threatened in New Jersey.

CWF is very excited to be partnering with NJDEP, Division of Watershed Protection and Restoration on a long-term study aimed at better understanding the effect of development on vulnerable species. We will measure abundance, adult health and survival, and larval growth of Pine Barrens tree frogs within a population impacted by encroaching construction to evaluate whether current wetland regulations, including buffer size, are sufficient for species conservation.

Note: For the health and safety of our staff, volunteers and the communities where we work, CWF staff and volunteers are practicing social distancing and following all state and CDC guidelines to prevent the spread of COVID-19.


Two days before Governor Murphy announced the statewide stay-at-home order, the first day of spring had sprung. Human life came to a screeching halt, but the natural world nevertheless began its annual transition towards warmer weather, longer days, and new life.

Osprey Numbers Surge Above Post-DDT Milestone

Statewide Census Documents over 650 nesting pairs in New Jersey

by Ben Wurst, Habitat Program Manager

An osprey prepares to land on a natural nest. Barnegat Bay, NJ.

Since we began to work more closely with ospreys in 2006, we have documented the population grow beyond the historic population estimate of 350-450 nesting pairs (Henny 1977) to a new historic milestone. In 2017, a total of 668 active nests were recorded during a statewide census of nesting ospreys, which is well above the post-DDT milestone of 500 nesting pairs, and show that the population continues to grow. This is the second census conducted without the use of manned aircraft since 2009 after all known osprey nests were released and mapped online in 2013. Despite the lack of aircraft, we’re still able to obtain an accurate representation of the size and health of the statewide population, while reducing the overall project cost. (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…)

Shorebird Expedition Brazil: The rights of traditional communities

Monday, February 27th, 2017

By Larry Niles, LJ Niles Associates LLC

Over the last few days of our expedition, we left the state of Para and flew to Sao Luis in the adjacent state of Maranhao. There we began the next phase of our work, trapping red knots, ruddy turnstones and other species, as we have done since 2014.

 

 

But prior to leaving Para, while we stayed in the village of Apiu Salvatore, the fishermen asked to meet with Max. He hadn’t planned it, so at first, the reason was unknown. The fishermen of the village knew Max represented ICMBio, and that Apiu Salvatore fell within Resex Gurupi-Piria, one of the Brazilian agency’s many extractive or Resex reserves. As I described in the previous post, ICMBio conserves natural resources in each reserve for the benefit of traditional communities, such as this one. So Max had a good idea what the community had on their mind.

 

David and Danielle prepare for the meeting with the fishermen of Apiu Salvadori.

 

We entered the large open meeting space under a thatch roof with a good breeze cooled by a sudden evening downpour. The association leader, Antonio, got down to business. He explained the problem of immense ships lurking offshore, spreading giant purse seines or immense lines of baited hooks, and stealing all the fish. It threatened their own lives, not only their livelihoods but their very existence. One could see very clearly how vital fish were to these fishermen. The community consumed virtually no goods; most of their daily needs came from the sea or their backyards. Chickens, pigs, even lambs filled backyards.  Fruit like mangos and avocados literally fell from the trees. I saw no washing machines, microwaves, coffeemakers, or nearly any of the appliances that litter a typical U.S. kitchen.

 

There was one modern device found in every hut and cabin, no matter how small or dilapidated. All had TVs.  How, I imagine, can they fit in this primitive world while gapping at the lives of the rich and famous? These were not people ignorant of the world, but unfortunately, they could be innocent as lambs when faced with the greedy schemers and politicians of Brazil. And as the ongoing corruption scandals here evolve, it seems like nearly every politician serves their own or other greedy interests.

 

So it is understandable that the fishermen’s first thought was to go to the Catholic Church. But then we came. So they asked for Max’s advice.

He quickly determined the fisherman had no idea they had legal rights to the fishery. He patiently explained the concept of ICMBio reserve system, the system of which they are a part. In theory, they could unify and certify their observations, take it to a judge and get a decision that would force the government to stop the theft by the international fishing fleet, at least in principle. Max and Danielle explained these rights and the group seemed sufficiently inspired. At least they left happy.

 

Why did they not know their rights? Max explained to me that the reserve manager for this area covered 60 other villages and that ICMBio has suffered 3 years of budget cuts. He reminded me how long it took to get to this village. So it’s the usual story familiar to U.S. agency biologists.  Here, as it is in rural U.S., but with a more obvious impact, starving good government often only starves the people who live on the land, the land itself and the wildlife, who depend upon it.

 

For me, it meant something more. We proposed this project to create better protection for shorebirds. We took the usual approach. First, do the surveys then will create scientifically defensible descriptions of the habitat’s value.  Finally, we overlay the threats: shrimp farming, oil spills, human disturbance, predators etc. then develop counter-measures.

 

I learned that nigh there is only one threat in this, one of the most important shorebird habitats in the world. It looms large above all others – if you erode ICMBio’s system of protection all the other threats will grow and decimate the fragile ecology of the area. Grow the ICMbio system and the traditional communities will enforce their legal right to conserve. They can monitor the threats and work with the agency to stop them. The laws already exist. The monitoring system is already in place. But this meeting pointed out they need more help.
