Marine wildlife is thriving in
the country’s biggest metropolitan area, and a rescue group is working to keep
it that way.

Stranded sea turtles usually
start appearing along the Northeast coast of the United States in late
November, as the animals that did not make it south in time to avoid falling
ocean temperatures become hypothermic and unable to swim or feed. But in the
fall of 2015, said marine biologist Rob DiGiovanni, “turtles started to
increase more in early December. Maybe because of the climate we had at the
time”—it was the world’s warmest November and December on record—“we had
animals come in alive on the 23rd of December, still able to be revived.”
As the executive director of the
Riverhead Foundation for Marine Research and Preservation, DiGiovanni runs the
only organization in New York licensed to assess and pick up stranded seals,
dolphins, and sea
turtles—all protected species under federal law—from the state’s
2,625 miles of coastlines, beaches, bays, and estuaries.
Nursing marine animals back to
health takes skill, dedication, and money. But the group’s challenge is to get
the word out that Long Island’s beaches—despite being nestled in the nation’s
most densely populated metropolitan area and best known as a summer party
destination—are also habitat for wild animals that need special treatment when
they show up onshore.
“Education and outreach are among
the biggest things we can do to let people know they’re here, that they’re
protected,” said DiGiovanni. “Maybe people are seeing animals but just assuming
that they’re not there, so sightings go unreported.”
Walking along a Long Island beach
in early February, DiGiovanni pointed to the “wrack line": a jumbled band
of seaweed, shells, and trash running parallel to the waterline, thrown dozens
of feet inland by the high tide. This was where cold-stunned sea turtles
typically turned up, he said, although it takes an attentive eye to spot a
brown-green animal lying, probably motionless, in the brown-black tangles of
sea kelp and driftwood.
“After high tide, walk the beach
and look at the wrack line for something unusual,” said DiGiovanni. “If you
find a turtle, don’t move it. Don’t touch it. Make sure it’s secure, and then
find a stick to mark where the animal is,” so that rescuers can find it—because
each length of beach looks much like another. And always call in the sighting,
DiGiovanni stressed, because hypothermic turtles may appear dead but may still
be saved, while dead turtles can provide scientists and wildlife managers with
valuable information.
We were not spotting any sea
turtles on this day—it was late in the stranding season to find survivors, said
DiGiovanni. But we were seeing plenty of litter. As we walked and talked, we
steadily filled a kitchen can–size garbage sack with cigarette butts, plastic
shopping bags, tangles of fishing line, and other plastic
trash, along with beer and soda cans.
“This might not seem like it did
a lot, but it made a difference,” said DiGiovanni as he tossed the bag into the
backseat of his car. “If you weren’t writing this story, that’s one bag of
garbage that would still be on this beach.”
In 2002, Riverhead rescuers
picked up a seal entangled in four pounds of plastic fishnets and line; a
picture of the animal features prominently in the Riverhead Foundation's educational
exhibit at the Long Island Aquarium, where it is based.
“Marine debris is something we
always see in our animals, and it’s not going away,” said biologist Samantha
Rosen, the Riverhead Foundation's education coordinator, who organizes several
beach cleanings a month through the group’s new “Pick
It Up” program.
Rosen, now in her mid-20s, first
got interested in marine mammals when her mother brought her to a whale autopsy
“with the people who are now my bosses,” she said. She went on to volunteer
with the group, then interned while studying biology at a nearby college, and
joined the staff about two and a half years ago.
“You’re excited that you get to
work with these animals,” she said, “and nervous because you want to save
them.”
The Riverhead Foundation gets an
average of 200 hotline
calls a year. In 2015 its rescue teams, which include staff and
volunteers, responded to calls about 71 stranded seals and 24
cetaceans—dolphins, whales, and porpoises. Less than halfway into 2016, the
group has rescued more than a dozen seals.
Of the 34 turtles Riverhead
picked up during the 2015–16 stranding season, there are 11 survivors: 10 green
sea turtles and one Kemp’s ridley, all endangered species. They swim in two
sizable standing pools in the group’s animal care area, a warehouse-size
expanse behind the aquarium’s exhibition space that also houses more than a
dozen wood-walled enclosures for rescued seals, each with a small tank of
circulating water. Plexiglas portholes allow staff to check on the patients
without adding to the animals’ stress.
It’s an airy, clean, well-lit
space, with the no-frills atmosphere of any veterinary facility: a place
optimized for tending injured and traumatized wild animals.
Off to one side, a small exam
room fronted by two-way mirrors offers an education opportunity to aquarium
visitors, who can observe unseen as animals rescued from the nearby beaches receive
care.
Rehabilitating a rescued sea
turtle or marine mammal doesn’t come quick or cheap. Seals usually need about
two months to recover, at a cost of roughly $10,500 per animal in housing,
medicine, and fish. Turtles stay in care for six to eight months, at a cost of
about $15,000 per animal, because they cannot be released until summer. Nursing
a dolphin back to health also takes months and costs up to $100,000.
The group relies primarily on
public donations and grants to meet expenses, along with some funding that the
National Oceanic and Atmospheric Administration provides to its marine rescue
network.
“When you look at a species
like the Kemp’s ridley, which is so endangered, any animal you can save is
important,” DiGiovanni said. “It’s what we do as a society, to care for
animals. We don’t want to see them suffer, so if there are things we have
introduced to the environment that cause them harm, having a program that can
respond to those harms is needed.”
With a staff of 11 employees and
two volunteer veterinarians, it’s a lot of ground to cover. But DiGiovanni
suspects that many stranded animals are never spotted. “We cover the hot
spots,” he said, but “until we can get better coverage of our beaches on Long
Island, we’re not going to really know the magnitude of the problem.”
Mendy Garron, the stranding
network coordinator for NOAA’s Greater Atlantic Region, which stretches from
Maine to Virginia, said that the group accomplishes an impressive amount of work
given its size. “Dead animal response, live animal response, and rehabilitation
and release. Some organizations might do two of these,” she said, while
Riverhead does all three and is also the region’s only marine mammal rescue
organization authorized to rehabilitate stranded cetaceans, such as dolphins.
“They don’t just do the response
and rehab but also are involved in aerial survey work for population studies,”
she said. “They do a lot of tagging work and also have expertise in large whale
necropsies—which we utilize both in and beyond the region. They’re not just
serving New York but benefiting the national network as well.”
Riverhead’s territory includes
New York City’s 520 miles of urban waterfront, where conditions pose
sometimes-insurmountable challenges. In 2013, the group experienced a public
backlash after opting not to rescue a common dolphin trapped in the Gowanus
Canal, a muddy Brooklyn waterway better known as an industrial
waste site than as a haven for marine life.
“Whenever we’re going to attempt
a rescue, we look at the safety of the animals and the rescuers,” DiGiovanni
said. “When we were talking with the police and fire departments, they said
they would not be able to rescue us if something happened. It’s very difficult,
but I think the people we had there made the calls that needed to be made.” The
experience and its aftermath were traumatic for his team.
Garron said that Riverhead made
the right call, particularly as common dolphins that show up so far from their
typical habitat far offshore are usually too sick or injured to recover. “Most
of the outcomes for those situations are not good—the animal dies or has to be
humanely euthanized,” she noted. “NOAA Fisheries has to do a better job of
getting that message out to the public. There is so much involved in what
Riverhead does that people don’t see and understand the whole picture.”
With 16 seals and 11 sea turtles
under care, Riverhead is looking forward to a spring and summer of returning
animals to the wild. Seals can be freed year-round, and the group intends to
release two this week. The turtles will have to wait for the return of summer warmth.
Releases attract hundreds of
residents, which helps spread the word about caring for New York’s marine life,
DiGiovanni said. “We’ve focused on getting good at this work. Now we need to
build the support system with the community.”
