The roads in Sea Isle City, New Jersey, can attain peak capability through the summer time months, nevertheless it’s not simply due to vehicular site visitors.
Each yr starting round late May, dozens of feminine diamondback terrapins—medium-sized turtles with a definite diamond-shaped sample on their shell—start their annual migration from the coastal marshes the place they reside, throughout the barrier island to the seashores and sand dunes the place they can provide beginning safely. For roughly two months, they battle the roadways, slowly strolling backwards and forwards from one facet to the opposite whereas making an attempt to outlive the numerous vehicles, vans and vans that move their means.
Diamondback terrapins are only one turtle sort in an unlimited world of turtle species. From the large tortoises of the Galapagos Islands to the inexperienced sea turtles that nest in Costa Rica’s Tortuguero National Park, the quantity of turtle range on the planet is excellent. However, whereas turtles have roamed the Earth for greater than 200 million years and have outlived dinosaurs, at this time, they’re among the most threatened wildlife on the planet. That’s why World Turtle Day and its mission of turtle conservation is so essential.
Beginning in 2000, World Turtle Day (May 23) highlights the significance of defending turtles and their habitat across the globe. It’s additionally the proper alternative to study turtle range and methods of serving to these extremely endangered creatures.

Why Are Turtles and Turtle Conservation Important?
From their dietary habits to the dispersing of seeds, turtles are important to sustaining biodiversity, and their disappearance would have a catastrophic impact on how ecosystems operate. Turtles assist preserve coral reefs by consuming organisms like sponges that compete for area. They dig burrows that different mammals can make the most of and are prey that different wildlife depend upon.
Nat Hab lately paired up with the Turtle Survival Alliance, an action-oriented non-profit that helps and manages restoration packages for endangered turtles and tortoises worldwide. As a part of a current Daily Dose of Nature, our weekly webinar collection, Jordan Gray, TSA’s communications and outreach coordinator, introduced with Nat Hab Expedition Leader Arpita Dutta on turtle range within the U.S. and TSA’s aim of zero turtle extinctions.
Here are a number of foremost takeaways from the episode:
What’s the Difference Between a Turtle and a Tortoise?
Turtles, tortoises and terrapins all fall underneath the “turtle umbrella,” which describes a reptile with a bony shell on its again. There are 476 residing species and subspecies of turtle and tortoise inhabiting Earth at this time, represented by 352 distinct species. Surprisingly, solely seven of those are marine, that means the majority of the world’s turtles really reside on land. These are those you may see meandering alongside the facet of a avenue, sitting atop a log sunning itself in your native park and even wandering throughout your yard.
“When it comes to turtle conservation,” says Jordan Gray, TSA’s communications and outreach coordinator, “there’s a whole other world of turtles out there [in addition to sea turtles] for us to focus on.”

Born within the USA
It seems that the U.S. has “far and away” the best turtle range on the planet, says Gray. There are 88 species and subspecies of turtles all through the nation (the subsequent nation even near the U.S. with regards to turtle range is Mexico, which has 65 species and subspecies).
Turtles are seemingly in every single place—within the Lower 48 alone, you’ll discover species just like the western painted turtles of the Pacific Northwest; desert tortoises residing all through the sandy flats and rocky foothills of the Southwest; leatherback sea turtles nesting alongside North Carolina’s barrier islands; and yellow mud turtles dwelling within the oxbow lakes and flooded fields of central states like Missouri and Kansas.
But whereas turtles exist from coast-to-coast, it’s the jap U.S.—and extra particularly, the Southeast—that’s thought-about a real biodiversity hotspot. In truth, the world round Mobile, Alabama, has one of many highest concentrations of turtle range on the planet, with not less than 18 distinct species residing among the many area’s slow-moving waters, corresponding to muddy rivers and soft-bottom salt marshes and swamps. These embrace black-knobbed sawback, Alabama red-bellied and Gulf Coast spiny softshell turtles.
The Many Risks Facing Turtles
Despite bigger, extra seen wildlife, corresponding to Arctic polar bears and Africa’s black rhinos, getting the majority of media consideration, turtles even have the next danger of extinction than these megafaunas. More than half of the world’s turtle and tortoise species are listed as critically endangered, endangered, or susceptible. One such species is the critically endangered Madagascar big-headed turtle, which is closely poached to be used as meals and as a part of the unlawful pet commerce. But whereas poaching is a giant challenge with regards to turtle dangers, it’s not at all the one one.

Habitat Destruction and Fragmentation
Human actions corresponding to setting up housing, establishing agricultural lands and logging, in addition to pure occasions like earthquakes and floods, can break up native ecosystems and have devastating results on turtle habitats and turtles normally.
The critically endangered lavatory turtle is one turtle species that’s notably affected by one of these habitat fragmentation. North America’s smallest turtle, lavatory turtles depend on fens—peaty wetlands that require a gentle supply of groundwater—to outlive. When their habitat is drained, divided and transformed into every little thing from farmlands to grazing areas for livestock, lavatory turtles are left remoted. They’re now residing in pocket wetlands, the place probabilities of their survival develop into slim.
Plastics and different Ocean Debris
Ocean particles, together with plastics, is a large menace to marine life. Sea turtles can get caught within the refuse and even feed on it, which may then block their intestines to allow them to’t digest meals. The toxins in sure plastics can result in infertility in male turtles. Depending on the sharpness of an object, it may well additionally rupture an organ.
Climate Change
While local weather change is affecting all of us, one turtle species that’s having an particularly important impact on is the wooden turtle, endemic to North America’s northeastern territory. While wooden turtles spend hotter months feeding on berries and earthworms in open fields, moist meadows and forests, they overwinter within the native waters, hibernating amid fast-flowing rivers and streams. However, hotter winters are resulting in elevated flooding, which very often seashores wooden turtles on land whereas they’re nonetheless in a semi-dormant state. If they don’t make it again to the water earlier than temperatures as soon as once more drop, they’ll freeze to demise.
Crab Traps and Fishing Gear
Turtles are typically interested in the bait utilized in blue crab traps. They push their means into the traps to feed and sometimes drown as soon as inside. Turtles can get entangled in fishing strains or die from swallowing hooks. The alligator snapping turtle, a bigger creature with a giant head and a ridged shell that resembles the pores and skin of an alligator and resides in cypress swamps and bayou throughout the southeastern U.S., together with Houston waters, is especially inclined to leisure and industrial fishing.
Ways to Help Protect Turtles
Here’s the excellent news about turtles: They’re resilient creatures. All we need to do is give them a serving to hand.
Thankfully, you don’t need to be a specialist or have a scientific diploma to help with turtle conservation. In truth, “citizen science” and a ardour for saving wildlife play an enormous half of their total care. There are varied packages within the U.S. the place you may act as a citizen scientist for an hour, day or week. It could also be taking part in a coastal cleanup or becoming a member of your city’s group board in an effort to guard native wetlands.
If you see a diamondback turtle crossing the road in oncoming site visitors, you may transfer it to the facet of the highway within the route that it was already going (bear in mind, nonetheless, to by no means deal with turtles unnecessarily).
Or, if a feminine diamond has been killed on the way in which to put her eggs, name an area wildlife middle and allow them to know. They can then rescue the eggs, hatch them and launch the infants again into the wild when prepared.
TSA presents volunteer alternatives that anybody can be a part of, together with snorkeling waters like Florida’s Weeki Wachee Springs and Comal Springs, in New Braunfels, Texas, to assist hand-capture turtles, measure and mark them. “The work can be rigorous,” says Gray, “but fun.”
Nat Hab additionally presents a number of expeditions that highlight turtles, together with its Galapagos adventures and Natural Jewels of Costa Rica journey. Your presence on these journeys helps promote sustainable tourism and conservation initiatives, together with people who assist turtles.
Another good way to assist transfer towards “zero turtle extinction” is a TSA annual membership ($50/common membership, $25/seniors). In addition to reductions on TSA merchandise and occasions, 100% of every membership price goes towards conservation motion. What a method to have a good time World Turtle Day!
