What’s Happening at Waterloo?

Tuesday, April 11th, 2017

By Allegra Mitchell, CWF Biologist

 

Waterloo Village in Byram Township, Sussex County is more than a tourist attraction and local gem, it is also home to the largest cross-road amphibian migration in New Jersey. Each spring, frogs, toads, and salamanders stir from their hibernation to make their way to their breeding sites. Some of these sites, like the one at Waterloo, are vernal pools – small, temporary bodies of water that appear in early spring as snow melts and rain and groundwater gathers, and disappear throughout the summer as they evaporate. The ephemeral nature of these pools can’t support fish, which would prey on amphibian eggs and larvae. Vernal pools therefore provide some protection for amphibian offspring, with many species such as wood frogs and spotted and Jefferson salamanders – both of which are listed as New Jersey species of Special Concern – relying exclusively on these vernal pools for breeding.

 

 

The greatest challenge for amphibians breeding at Waterloo Historic Village is crossing Waterloo Road. Living in the most densely population state takes a toll on many species of wildlife in the form of habitat loss, degradation, and fragmentation. Each year, many amphibians become victim to vehicular collision as they move from their hibernation sites across Waterloo Road to the vernal pool in which they reproduce. Amphibians may be disproportionately affected by vehicle-caused road mortalities compared to other wildlife because of their tendency to migrate en masse to breeding sites. These annual road mortalities can have devastating effects on amphibian population sizes, especially for the local at-risk salamander populations. In fact, as little as about 10% annual risk of road mortality in spotted salamanders can lead to the local extinction of an entire population.

To address this problem, the Conserve Wildlife Foundation of New Jersey (CWF) and the New Jersey Endangered and Nongame Species Program (ENSP) organized amphibian rescue efforts. Since 2002, dedicated volunteers have assisted frogs, toads, and salamanders across Waterloo Road during the busiest migration nights. This aid has proven effective in reducing amphibian road mortalities, but it is not a permanent solution to the problem. Efforts are underway to construct under-road tunnels to help guide amphibians safely across Waterloo Road. These tunnels will provide safe passage for these critters throughout the breeding season, including on their migration back into the woods where they will hibernate. Since this return migration is more sporadic and less weather-dependent than migration to the vernal pool, it is much harder to protect amphibians as they make their way back to the forest.

 

 

This year, CWF scientists have begun the initial phases of research to understand current amphibian population sizes and the impact of vehicle traffic on these animals at Waterloo. Scientists and volunteers have been out 7 days a week since amphibian migrations began in late February to tally daily roadkill on Waterloo Road. This study will be used to evaluate changes to frog, toad, and salamander populations as the under-road amphibian tunnels are installed. CWF scientists have also conducted egg mass counts in the vernal pool at Waterloo Village to estimate the current population sizes of the different amphibian species in the area. Having this knowledge will allow CWF to improve on future projects to minimize road-related human-wildlife conflicts.

Along with improving conditions for amphibians in this location, CWF’s work at Waterloo Village will serve as an example of New Jersey statewide initiatives to reconnect wildlife habitat as a part of the Connecting Habitat Across New Jersey (CHANJ) program. The goal of CHANJ is to make our state landscapes more permeable to wildlife movement so that all of New Jersey’s residents – human and wildlife – will have the space they need to thrive.

 

In an effort to bring people and wildlife together in a positive way at Waterloo Village, CWF scientists are leading educational walks for the public and local schools. Through hands-on interaction, local residents can learn about and appreciate the remarkable wildlife right in their own back yards and what they can do to support conservation efforts.

 

All New Jerseyans can help wildlife this season by planting native plants for their gardens, building bat boxes where bats can roost, and, of course, by keeping an eye out on the roads, especially on warm, rainy nights when amphibians might be migrating.

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.

Shorebird Expedition Brazil: Trapping shorebirds in Panaquatira

Saturday, February 25th, 2017

By Larry Niles, LJ Niles Associates LLC

The capture of Arctic nesting shorebirds first brought us to Brazil in 2013.  We brought 125 geolocators and caught both ruddy turnstones and red knots, attaching 85 on the former and 30 on the latter.  But we also came to create a new perspective on shorebirds in this place, one of the most important shorebird habitats in the world.

 

For all intents and purposes, shorebird work in this area started in the mid 1980’s, when Canadian biologists, Guy Morrison and Ken Ross surveyed from an airplane, the entire coast of South America.  In this monumental and dangerous survey they established an invaluable historic baseline of the number of Arctic nesting shorebirds wintering in South America. This was before shorebirds caught the interest of the public, and way before foundations and agencies devoted significant funding or staff time.  They surveyed the entire continent, but on the coast of Maranhao and Para they found the motherlode of shorebirds.  They did not, however, get close and personal.

That challenge belonged to a team led by the late Allan Baker of the Royal Ontario Museum and Ines Serrano, then with CEMAVE, the Brazilian counterpart of USGS.  They also flew the coast but followed up with a ground survey and the capture of a small group of red knots. Along with Guy and Ken, their work cemented the hemispheric importance of this area.

Over the last 4 years we captured knots, turnstones, sanderlings, whimbrels, collared plovers, semi-palmated sandpipers, semi-palmated plovers as well as South American terns and other species. Last year we recaptured 20 geolocators in a catch of over a hundred ruddy turnstones.  But only in 2013 were we able to catch red knots. Although abundant in the region, populations are estimated at 10 to 15K, they are remote and elusive.

 

So we were happy to find on our first day of surveillance this year over 400 red knots. They roosted within a flock of about 1000 shorebirds located at the west end of a small working class beach resort called Panaquatira, about an hour out of Sao Luis. The flock including black bellied plovers, semi-palmated sandpipers and plovers, collared plovers, South American terns, Black Skimmers and a few whimbrels. We readied that night for an early morning attempt.

 

First we needed to figure out the tide. It rises and falls 13 feet in northern Brazil, twice that in Delaware Bay. The spring tide or full and new moon tide increases the range to 18 feet.  Consequently, the high tide line moves every day and catching birds with a cannon net depends on placing the net near the predicted tide line, because birds move with it to stay as far from the dangers lurking on dry land. Wind speed and direction changes the high tide line, and so does barometric pressure.

 

So much rides on where we place the net. On our first two attempts, we missed by just a few yards, but it could have been a mile. The birds moved with the tide and stood just outside the 30 by 100-foot area within which the birds must be to be caught. We tried moving them but they spooked and most gradually left the area altogether. Ultimately, we fired but caught only two knots and two whimbrels.

 

We were blessed on the third day. We arrived near dawn, over four hours before high tide so we had plenty of time to measure elevations. We knew the morning’s high would be about four inches lower than the previous night’s high, which snaked along the sandy peninsula used by the birds to roost. Standing on the tide line we used a method borrowed from Clive Minton to determine the location on the beach four inches lower.

 

Laying my head flat on the sand I trained my eye towards the horizon. This establishes a level line. Using her hand, Stephanie marks four inches on her leg than moves until the four inch mark lines up with the level line. Her location depends on the slope of the beach. In this way we determined the location of the tide line four hours hence. We dug in the net.

Larry Niles and Mandy Dey take training on measuring elevation from Clive Minton in Australia.

At about an hour before high tide, shorebirds started crowding into the area around the net. At first, oystercatchers, black bellies, short-billed dowitchers and a small flock of skimmers. Most of the knots hung back on an adjacent sand bar. With a little push, they too piled in right into the catch area.

 

We fired and caught 175 knots, 30 sanderlings, 20 short-billed dowitchers and 5 black-bellied plovers. Among the knots were 3 with geolocators. We flagged, banded and measured 145 birds, all the while releasing unprocessed birds that appeared stressed by the heat. By late afternoon we were back at the house cracking open beers. We completed all our objectives with one day to spare.

One of the many values of catching shorebirds is examining their condition and molt. Here we compare two knots, an adult on the right and a second year or sub adult on the left. The latter molts its flight feathers much earlier than adults and it shows in the fading to brown. (Photo by C. Buiden).
