Easter Sunday is a celebration of rebirth, resurrection, springtime, life.  And this Easter Sunday – right on cue – a warm day turned into a mild night, the mild night met with rain, and together they gave rise to lots and lots of life.   The amphibian migration was underway…in a big way!

 

Our teams were ready.  Despite heavy bellies and a long day with family, at least 50 trained volunteers came out to “guard” the animals at road-crossing hot spots.  From nightfall to around 11:00 pm we escorted, ferried, and tallied more than 3,000 salamanders and frogs across! (Numbers are still coming in from other teams.)

It was a heart-pounding pace, often with multiple animals entering the roadway at once.  They didn’t seem to understand the danger, but we humans were darting in and out, racing against car tires and grabbing up slippery critters as fast as slippery critters can be grabbed…while still being safe, orderly, and polite to passing motorists.  A lot of drivers stopped to see what all the speed-walking was about.  One woman said “God bless!” when I showed her a fat female spotted salamander and told her about the migration.  Another guy must have been a local because he just asked “how many tonight?”

 

Everyone had an exhilarating night – the kind of migration night we plan for but don’t often get.  It was a lot of fun and we saved a lot of lives.  From the vehicle count, most of those little animals wouldn’t have stood a chance.  A few still didn’t.

Before heading home from the site where I was working, I took a midnight stroll down to the vernal pool.  It’s so neat to watch salamanders swimming around.  Especially the big spotted salamanders.  They spend almost their entire year underground in the woods, yet they are graceful and natural in the water.  They even look excited to be there, swirling around each other in contest and attraction.  I felt lucky to know about this wonderful thing.  It felt great to have made some of it possible.  Look at those gorgeous animals!  And their impossibly bright yellow spots!  They are colors lost in the night, but not by our watchful lights.

Following Monday’s all-night amphibian foray – and the prolonged terror/adrenaline rush of playing real-life Frogger – I drove home through a rainy sunrise on Tuesday.  According to a weather app on my phone, the rain would keep falling all day and end (wouldn’t you know) right around sunset.  “You gotta be kidding me,” I think is what I slurred.

Warm nighttime rain is the simple cue for mass movement, like what we had before dawn that day.  But nature is seldom that simple, so the task of monitoring an amphibian migration can get hairy.  The warm, soaking daytime rain would get the attention of those slumbering frogs and salamanders. Even if it stopped before dark, the wet ground and road would entice some of them to move.  Maybe a lot of them?  And right at the time when nighttime traffic would be heaviest on the roads.

So we sided with caution and rallied the teams to hit the streets at dusk.  I went back to Byram to lead a group of volunteers there while others covered different hot-spots. 

The rain did end early – earlier than expected even – and by nightfall our team was spreading out over a damp road.  It was a relief to see that a migration was happening anyway, albeit at a slower pace.  And the cars were filing through our setup (cones and signs, buffered by police) in threes and fours…99 vehicles in the first hour!  Basically, there was a car for every salamander that dared to cross the white line.

We did our best to stay ahead of the traffic.  By 11:00 pm the temperature was dropping, the road was drying, traffic was slowing, and so were the amphibians.  We paced the road below a starry sky with Orion front and center.  We had tallied another 175 spotted salamanders, 41 Jefferson’s salamanders, and 52 spring peepers.  Despite the heavy car flow early on, more than 85% of those animals made it to the safe side of the road – and eventually to their breeding pool below – with a little help from some friends.

The ingress migration to the pools is probably close to half-over across much of NJ, so we’ll be out few more times yet! 

 

THANKS to all the dedicated people who have helped so far.  It’s a diverse group of heroes, from long-time amphibian crossers like George Cevera and Carl Bernzweig, to new volunteers like Karen Ruzycki.  We have help from local partners like Margaret McGarrity of Byram Township, and engineering students from NJIT who want to help design solutions to the roadkill problem.  A couple reporters came out this week to cover the story and ended up shuttling amphibians, too.  We thank the Sussex County Division of Engineering for issuing us the permit to assemble on their road.  Thanks also to the Byram Police Department for their willingness to provide traffic control and their respect for our project, which I’m sure seems a little unusual.   And that’s just at one location.  Great job, everyone!

POST #2 ON THE 2013 AMPHIBIAN MIGRATION

by MacKenzie Hall, Amphibian Crossing Project Coordinator

 

The past week has been like a wild trip through biomes and time zones.  A half-foot of wet snow buried NJ on Friday, but it didn’t stand a chance against a  sunny weekend above 50˚F and the valiant arrival of Daylight Savings Time.  Bam!  Spring.  Suddenly birds were singing, crocuses were blooming, and salamanders were stretching their hamstrings for the journey ahead.

Throughout the day on Monday (March 11) a long wall of rain crept eastward across the US.  It couldn’t possibly miss NJ, and the temperature would hold around 50˚F overnight – excellent predictors for a migration.  The question was when the rain would hit and whether a rainfall starting very early in the morning would trigger many amphibians to move.  There seem to be almost unlimited permutations for how the important factors of ground thaw, temperature, rainfall, date, and time of night can converge, and after almost 10 years with the Amphibian Crossing Project I still learn new and surprising things.

A handful of us chose to wait out the rain at one of our big road-crossing sites in Byram (Sussex Co.).  At least 3 hours before the rain even started, someone noticed a salamander crossing the dry road.  We spread out to cover more ground and kept counting.  By the time the first raindrops hit we had already tallied (and ferried) 190 salamanders and 20 frogs across the asphalt threshold dividing their forest habitat from the breeding pool below.  We were all pretty surprised and excited by what we were seeing.

The rain came around 2:30 am, and in the 4 hours before dawn the road was swimming with frogs and salamanders.  We did our best to keep up with the count, and the rescue, especially as vehicle traffic picked up toward dawn.  Eight cars per hour around 3:00 am, then 10 cars per hour, then 26.  By 6:15 it was hard for the last of us – Bob Hamilton and I – to keep our feet on the pavement as the vehicle count crested 100 per hour.  We also started to lose the battle against roadkill – as many animals were getting hit as we could save.  Luckily it was just a short period, and at dawn the migration would pause.   Our totals for that night:  1,119 salamanders and frogs, 954 of which made it to their destination!

Our “scouts” all across northern & central NJ had similar reports.  A big migration had happened before dawn, and there was some roadkill as evidence.  But you can listen for a happier kind of evidence – the honking and peeping of those who made it to their pool.  The harbingers of spring are arriving.

Volunteers Survey New Jersey’s Eagle Population…

Every January NJ participates in the National Midwinter Eagle Count.   Volunteers surveyed for eagles statewide during the weekend of January 12th & 13th.    Due to dense fog the visibility was poor in many of the survey areas but despite this the total count was  297 bald eagles.  This is 38 less than 2012’s high count of 335 bald eagles.  Four golden eagles were also counted during the survey.

2013 Midwinter Eagle Survey Results

  • Southern NJ: 264 bald eagles
  • Northern NJ: 33 bald eagles
  • Total bald eagles: 297

Thank you to all volunteers who participated!

February is a great time to get out and view eagles in New Jersey.  So far twenty-one pairs of eagles are incubating (on eggs) while others pairs are busy getting ready for the season.  Not only can you spot resident birds this time of year but wintering eagles as well.  The Cumberland County Winter Eagle Festival takes place this Saturday the 9th. This is a good opportunity to see eagles and other raptors and learn more about them.  I’ll be there at the CWF table so stop by and say “Hi”.

On Saturday, January 19, Conserve Wildlife Foundation of NJ (CWF) will host an osprey platform construction day from 10:00 am to 3:00 pm at Tuckahoe Wildlife Management Area in Woodbine, New Jersey. Volunteers who signed up in advance are helping to build up to 20 new platforms to replace those lost or damaged in Superstorm Sandy.

Constructing these platforms now will allow CWF time to install them before the start of the osprey nesting season in April. Ospreys mate for life and typically return to the same nest year after year.

Since Sandy slammed into the coast of New Jersey in late October, biologists with CWF have been actively surveying and assessing damage to habitat that wildlife needs to survive. Many osprey nesting platforms were right in the middle of the high winds and strong storm surge associated with Sandy. The majority of the platforms weathered the storm; others need repairs or must be replaced. We have already installed 5 new nesting platforms. Two platforms were installed on December 1st on Herring Island (N. Barnegat Bay) in an area of homes that sustained significant damage. The other three platforms were installed in the Wildwood area.

The Conserve Wildlife Foundation is a small staff with a lot going on.  If you glance through our conservation projects, you’ll see that volunteers have a role in almost everything we do.  This hardy fleet of dedicated helpers allows us to cover more ground, stretch our dollars, reach wider audiences, and continue our upward and outward evolution as a group.

We’ve featured a handful of people on our Volunteer Profiles page so far, with Robert Hergenrother being the most recent.  We enjoy learning more about their unique backgrounds and interests and hope you’ll check them out, too.  

Thank you to ALL of our wonderful volunteers!

CWF VOLUNTEERS GO “CAMP” ing

RESULTS FROM THE 2012 SURVEY SEASON.

When people first hear the word CAMP they might think of going out in the woods and setting up a tent, but CWF’s CAMP project is all about monitoring New Jersey’s amphibian population. CAMP stands for the Calling Amphibian Monitoring Project.

In 2012 33 volunteers participated and surveyed a total of 33 routes out of 63. Volunteers conduct roadside surveys (after dusk) for calling amphibians along designated routes throughout the state. Each 15-mile route is surveyed three times during the spring. Each route has 10 stops, where volunteers stop, listen and record all frog and toad calls for 5 minutes.

In 2012 15 out of the 16 New Jersey amphibian species were detected. The only species not detected was the Eastern Spadefoot.  Northern Spring Peepers were the most common species detected on 31 of the routes while Green Frogs were detected on 22 routes.  Both the American Bullfrog and Southern Leopard Frog were heard on 16 of the routes.

In NJ there are four frog and toad species of conservation concern; the Southern gray Treefrog  is a state endangered species, the Pine Barrens Treefrog  is a state threatened species, and the Carpenter Frog and Fowler’s Toad are both  special concern species. The Southern Gray Treefrog was detected on 2 of the CAMP route, the Pine Barren Treefrog on 3 of the routes, the Fowler’s Toad on 13 of the routes and the Carpenter Frog on 7 of the routes.

CAMP data is entered into the North American Amphibian Monitoring  Program (NAAMP)  database housed by the USGS Patuxent Wildlife Research Center. All of the occurrence data for these species is  extracted from the NAAMP database, quality checked for validity, and entered into the Biotics database by CWF & ENSP staff. These data will then be used in future versions of the Landscape Project maps.  These maps are used by planners in various state, county, municipal and private agencies to avoid conflict with critical wildlife habitat.

Thank you to all CAMP volunteers!

2012 is a Record year for nesting bald eagles in NJ.

NJ Bald Eagle population continues to increase.

In 2012 a new record high of 135 eagle pairs were monitored during the nesting season. One hundred and nineteen of those were active which means they laid eggs.  A total of 165 young were produced this year and fledged (left the nest). That is 46 more than 2011’s 119 young produced.  Twenty-seven new eagle pairs were found this season, 15 in the south, 2 in central and 10 in northern NJ.  While all of these numbers are good news for NJ eagles they still need protection.  The two major threats that bald eagles in NJ face today are disturbance and habitat loss.

The NJ Bald Eagle Project has a dedicated group of volunteers who monitor nests throughout New Jersey.  They help to prevent disturbance at nest sites by educating the public about eagles.  The success of the eagle project is directly related to these wonderful volunteers.

Volunteers needed!

Since 2009, we’ve been active in helping to restore wildlife habitat to a former golf course in lower Cape May County. In place of the large lodge on the site we are building a “Backyard Habitat Demonstration Site.” It will feature several different habitat treatments that homeowners can use to provide habitat for wildlife in their own backyards. It includes the creation of scrub-shrub habitat, forested habitat, nectar producing plants, wildflower meadows, a pond, and a brush pile.

The site was designed by landscape designer Jeanne Marcucci with greenjean gardens LLC. Last week the site was prepped by NJ Fish & Wildlife. After the site was plowed we laid out paths that run throughout the site. Next compost will be spread to some areas (wildflower beds) and plants will be delivered on October 9th. The team at Planet Earth Landscaping will be assisting us the the compost spreading and planting.

Volunteers are needed to help plant the many native plants that were ordered on October 10-11th from 10-2pm each day. For more information or to volunteer contact Ben Wurst.

Landowner Recognized…

for his contributions to the NJ Bald Eagle Project

by: Larissa Smith, Biologist/Volunteer Manager

Landowner Robert Johnson with Eagle Project volunteers Earl and Mary Ellen Holton.

Landowners are an important component of the NJ Bald Eagle Project since fifty-six percent of  eagle nests are found on private property in NJ.  This year we recognized a landowner for his contributions to the project over the years.  Mr. Robert Johnson has had a pair of eagles nesting on his property in Cumberland County since 2003.  He has always been very protective of the pair and makes sure that they aren’t disturbed during the nesting season as well as keeping the nest observers updated on any activity that he has seen or any problems. He helps the volunteers by cutting the grass in his field so that they can drive in and park when monitoring the nest. This year when the volunteers truck got stuck in the mud at another close by nest Mr. Johnson came with his backhoe and pulled them out.

Mr. Johnson received a certificate of appreciation and an  eagle frame handmade by CWF biologist Ben Wurst www.reclaimednj.com.  The photo in the frame was of Mr. Johnson holding an eagle chick during a eagle banding on his property.

On behalf of the NJ Bald Eagle Project we thank Mr. Johnson for his dedication to NJ eagles.
