Tortuguero is
one of Costa Rica's most popular ecotourism destinations – a microcosm
of rainforest, freshwater and marine biology. This untamed stretch of Caribbean Coast is connected to Limon,
the region’s only port city 50 miles (80 km) to the south, by a series
of rivers and canals that parallel the sea. It is a special and widely
varied ecosystem web of marshy islands, beaches, canals, lagoons and
dense rainforest that is habitat for a multitude of animal and plant
life. A trip through the serpentine maze of canals is likened to
cruising on the Amazon, albeit on a much smaller scale.
In this
steamy labyrinth of coastal rainforest, swamps and waterways, live
howler, spider and white-faced monkeys, three-toed sloths, caimans,
crocodiles, about 405 species of birds, myriad amphibians, reptiles and
insects, and animals threatened with extinction like jaguars, tapirs,
Great Green Macaws, and West Indian Manatees.
Tortuguero National Park’s beach is recognized as the Western
Hemisphere’s most important nesting site for the endangered Green Sea Turtle, and a major nesting site for the critically endangered Hawksbill and Leatherback sea turtles.
West Indian Manatees
Swimming slowly and gracefully underwater, resembling
more a pale cousin to the walrus (minus the tusks) than a mermaid from
old sailors’ lore, the West Indian Manatee lives a near-secret life in
secluded canals of Costa Rica’s Tortuguero National Park.
The
world’s fragile West Indian Manatee population is endangered and was
thought to be extinct in Costa Rica until a small group was located in
remote lagoons within the Tortuguero National Park. The gentle marine
mammals live in warm tropical waters that once ranged from the Southern
United States down the Caribbean to Brazil. Today, only a few small
populations remain in isolated pockets around Florida and Central
America’s Caribbean waterways. The re-emergence (or rediscovery) of a
manatee population is very significant, states the Save the Manatee Foundation.
“Tortuguero's
manatees, which were considered locally extinct less than two decades
ago, have made a remarkable recovery, but we still do not know whether
or not there is a viable population,” reports the Save the Manatee
Foundation, which is dedicated to protecting Costa Rica's remaining
population of manatees around Tortuguero. Estimates show perhaps 100
manatees inhabiting the lagoons of Tortuguero and Barra del Colorado.
The large, pale grey or brown marine mammals
measure about 3.65m (12 ft.), weighing up to 800 kg (2,000 lbs) and are
herbivores, eating only sea grasses. Their large snouts and sensitive
mouth whiskers give them a walrus-like resemblance, though scientists
say they are more closely related to elephants. They
have flexible front limbs which they use to steer while swimming and to
push food into their mouths, or to hold them up on sandy bottoms, and a
large paddle-shaped tail that pushes them through the water at 1-3 km
(3-5 mi) per hour.
Manatees have a voracious appetite, which helps
to keep them warm; they eat up to 10 times their body weight each day –
about 40kg (100 lbs) of plants. Being mammals, they breathe air and
must rise to the surface every 15 minutes or so to breathe, more often
when active. The animals are solitary, coming together only during mating season and for the first two years of a calf’s life when it stays with its mother.
In
the past, manatees were hunted for their flesh to eat and for their
very tough hides. But in more recent decades, the greatest threat has
been chemicals and sediments washing into Tortuguero’s waterways from
banana plantations. Although manatees have returned to the area, they
are being squeezed between steadily expanding agriculture and increased
human traffic. Ironically, the boom in ecotourism is taking a toll with
escalating boat traffic. Fast motor launches full of tourists heading to
the beaches and eco-lodges of Tortuguero race through the lagoons and
rivers, and collide with slow-moving manatees or scare them away.
Manatees have moved west in Tortuguero toward more remote lagoons,
seeking quiet places to mate and are rarely seen, making it difficult to
study and research the unusual creatures. Taking a tour of the canals by kayak is your best bet for trying to spot the elusive manatees.
Sea Turtles
The Tortuguero coast of Costa Rica’s northern Caribbean region is a 22-mile-long,
desolate,
volcanic black sand beach littered with driftwood and tree logs tossed
up on shore from wild ocean storms. There is nothing but beach and low,
swampy jungle for miles and miles. You can’t swim here because of rough
surf, strong currents and sharks that will eat you – adding to the
isolation.
That’s just perfect for the Green Sea Turtles and
Leatherback, Hawksbill and Loggerhead sea turtles that have been coming
here since at least 1592, according to scientific records, to nest and
hatch their young in Tortuguero’s extreme solitude.
The
name “Tortuguero” means “turtle catcher” in Spanish, and the turtle
population came perilously close to extinction in the 1960s when nearly
every female turtle arriving to lay its eggs was killed for turtle soup.
The Caribbean Conservation Corporation, now known as the Sea Turtle Conservancy,
put a stop to that after renowned sea turtle expert and ecologist Dr.
Archie Carr founded it in 1959 to study and protect the Caribbean sea
turtles. The Tortuguero National Park was created in 1970 and preserves
more than 46,900 acres (19,000 hectares), along with the 22 miles of
nesting beach, making it one of the largest remaining lowland wet
tropical forests in the country.
It is one of the most visited
sites during turtle nesting and hatching season. Some 50,000 tourists
show up annually. From July to October, the Green Sea Turtles arrive en masse to nest. March to July brings the giant Leatherback Sea Turtles and Hawksbill turtles
nest from May to November. Only female turtles come ashore to nest,
usually under the protection of night when it is cooler, mysteriously
returning to the exact beach where they were born
During
these months, thousands of huge female turtles crawl their way up the
beach to dig their nests, lay their soft, golf ball-size eggs, and
return to the ocean. In 2010, there were 180,310 Green Sea Turtle nests,
the highest year on record, equating to a nesting population of 30,000 to 60,000 female turtles, according to the Florida-based Sea Turtle Conservancy.
Incubation
takes about 60 days, and then hundreds of tiny four-inch-long sea
turtle babies hatch all together and race to the sea. Some nights, the
beaches are swarming with sea turtles. It’s an exciting time. They're
like little windup toys with their little flippers paddling away to
cross the sand out into the surf. Visitors are able to respectfully
witness the “circle of life” on guided tours; no one is allowed on the
beaches unaccompanied after 6:00 pm to prevent poaching.
Sea
turtles grow slowly, taking about 15-50 years to reach maturity,
depending on the species. It is theorized that some species can live
over 100 years, though there is no way to determine the age of a sea
turtle from its physical appearance. What scientists do know is that
turtles have been swimming Earth’s waters for a long time – the earliest
known sea turtle fossils are about 150 million years old. However, the
Sea
Turtle Conservancy reports that only in the past 100 or so years, the
world’s sea turtle population has dwindled dramatically as humans have
killed them for their meat, eggs, skin and colorful shells. Destruction
of areas where the turtles feed and nest, and pollution of the world's
oceans, are all taking a serious toll on remaining sea turtle
populations, notes the Sea Turtle Conservancy.
Tortuguero
Ecotourism
has helped Tortuguero preserve its natural resources and culture by
providing employment to former turtle hunters who now guide tourists to
the turtle nesting beaches. Costa Rica’s West Indian Manatees are
another potential ecotourism draw that can elevate their protected
status like the sea turtles, along with creating additional jobs and
needed revenue for the community. Protecting the manatees’ waterways
from encroachment by banana plantations and road construction will not
only protect the environment but also will help keep Tortuguero's unique
features – its isolation and distinctive ecosystem – intact.
