Those tiny bursts of white along wooded edges and roadways are reassurance that spring is near. These are the shadbush flowers, and their appearance in late March once signaled the annual return of shad to the Bay. Abundant American shad and its delectable roe became a Lenten favorite in the Maryland Tidewater, but have been off the market for years.

About Terrapin Institute

The Terrapin Institute began in 1998 as a consortium of concerned citizens, scientists, resource managers, and educators dedicated to the understanding, persistence, and recovery of Diamondback Terrapins and other turtles through effective management, thorough research, and public outreach. We work to protect an abundance of adult turtle populations, preserve nesting and forage habitat, and improve recruitment. In return the terrapin has become the perfect metaphor for natural resource stewardship and public engagement; the face of estuarine restoration, and a gateway to the many wonders of our rich tidewater heritage.

   Those tiny bursts of white along wooded edges and roadways are reassurance that spring is near.
These are the shadbush ﬂowers, and their appearance in late March once signaled the annual return of
shad to the Bay. Abundant American shad and its delectable roe became a Lenten favorite in the
Maryland Tidewater, but have been off the market for years. 
    Dogwood blooms oﬀer participants in another famous ﬁshery warning. Striped bass ﬁsherman used
to rely on the ﬂowering dogwood tree as an indicator that spawning had occurred and it was “safe” to
harvest. A little later in the season when the native locusts are in full bloom, watermen know that the
blue crab has had its first of many molts and is now prime for picking. 
    For the tidewater gardener, there is a lesser-known native wetland plant, known as turtlehead due to
the shape of the ﬂower, that blooms in August. When nature goes as planned, turtles of various species
begin to hatch in late summer after 60 or so days of incubation in earthen nests. The bloom of the
turtlehead plant reminds us to watch out for newborn turtles. The Maryland landscape is amazingly
synchronized with those treasured secrets of the Bay. 
    Perhaps the most captivating of seasonal mileposts are diamondback terrapins. Terrapins are turtles
and were among the earliest of American species to be classiﬁed. Terrapins are distinct in that they
inhabit brackish waters exclusively and are believed to remain in their natal waters or small home
range year-round throughout their lifetime. In areas where natural shoreline habitats remain unaltered,
terrapins may use the same nest site year after year. 
    In the Mid-Shore clime along the shoreline and in waterfront gardens it is not unusual to ﬁnd terrapin
hatchlings emerging in late March and April. These little gems are most likely from last year’s nests, in
which they’ve hatched from the egg, but stayed in the underground vessel-shaped excavation and
overwintered for seven or eight months. Typically, these hatchlings are fully developed with cardboard-
thin shells and are desperate to ascend on the ﬁrst warm day of spring. Sadly, many hatchlings
determined to leave the nest at this time may be left vulnerable when the ﬁckle Maryland weather
quickly shifts back to winter, leaving the tiny terps exposed and cold-stunned. 
    After spring has fully set in we become spectators in nature’s most extravagant event. Here in the
tidewater, it’s Marsh Madness; all turtle species are on the move again, seeking suitable nesting and
forage areas, many times living dangerously in the middle of the road in oblivious pursuit to secure the
species. (If it is safe to stop, motorists are urged to move turtles oﬀ the road, placing the turtle in the
direction in which it was traveling. Be extra careful with snapping turtles, which should be regarded
equally as treasured wildlife and moved with aid of a shovel.) As demonstrated in the Tidewater Times
article of July 2000, please try to schedule grass mowing to avoid peak nesting times.
    Terrapins are a signiﬁcant part of the tidewater heritage: entire chapters of Maryland law have been
dedicated to terrapin conservation; delicacies such as terrapin originated in Crisﬁeld in the late 1800s
and proceeded to “spread the fame of the Chesapeake ’round the world,” Mark Twain, H. L. Mencken
and Winston Churchill listed terrapin as a favorite dish, the Baltimore Terrapins were a team in the
short-lived Federal Baseball League; at the encouragement of Crisﬁeld’s Curly Bird, president of the
University of Maryland, the terrapin became a most unusual mascot in 1933; and most recently the
diamondback terrapin was declared the State Reptile. 
    Eventually, as Americans coped with conspicuous consumption, Prohibition, war, and income taxes,
the diamondback terrapin slipped oﬀ the menu and back into the marshes for a brief respite. According
to agency reports, harvests of wild terrapins dropped oﬀ signiﬁcantly in the 1950s as only the diehard
tidewater traditionalists continued to serve terrapin. 
    Unfortunately, by the year 2000 the diamondback was headed for another distinction. Along with
sturgeon, sheepshead, and shad, to name a few, the terrapin was headed for commercial extinction. An
aﬄuent global market and liberal commercial ﬁsheries regulations put Maryland’s terrapin in the
crosshairs of another collapse. When state managers could not be convinced of the pending disaster,
advocates persuaded the Maryland legislature to intervene to manage the terrapin harvest. 
    In 2007, after three years of political angling and a poorly conceived ﬁshery management scheme,
Maryland’s revered terrapins were ﬁnally taken oﬀ the market. (The future of terrapin conservation
remains unclear, but conservation news and ways for citizens to advance the cause will be reported
here on these pages and at www.terrapininstitute.org.) 
    Meanwhile, back on the Bay as the waters warm in brackish tributaries, around late April or so,
terrapins begin to congregate in bails of twenty to thirty. More often we’ll see just their heads breaking
the surface. These may be mating groups, which have emerged a month prior from a long winter’s nap
in the bottom mud, typically in water depths of about ten feet in the quieter coves of the tidewater
system. The larger heads belong to females, which can weigh about ﬁve pounds, and the smaller,
snake-like heads are the males, which weigh significantly less, about a pound and a half. 
    The terrapin spends most of its life in shallow brackish waters and uses land only to nest. The
species occurs from New England’s Cape Cod all the way to Texas. Seven sub-species have been
classiﬁed. The Chesapeake variety is the largest and hardiest.    Both male and female terrapins are
known to bask at the water’s surface and along the shoreline as a means of jump-starting their
metabolisms. In this region terrapins are active March through mid-December and may become
trapped in stone revetments, crab pots, fyke nets and other ﬁshing gear and snagged on ﬁshing hooks.
Otherwise, terrapins are essentially inactive while tucked away and overwintering in the bottom of the
Bay. Oyster dredging, spoil placement operations and marine construction may impact terrapin
populations during winter months. 
    By mid-May, as days lengthen and temperatures rise, we may notice terrapin heads just oﬀ shore,
surveying for nest areas. If spring is oﬀ by a few weeks, expect the terrapins to be also. These animals
are highly dependent on temperatures and have been observed surfacing on a warm winter’s day.
During a cool spring, typical terrapin behaviors may be delayed until mid-June. 
    Once things start, look out. Large, lumbering females begin the nest march in late May and continue
through mid-July. Nesting females may target the same general nest area year after year. The bulk of
the land-based terrapin activity may occur during the ﬁrst three weeks in June. We’ll see them crossing
roads, boat ramps, golf courses, and lawns, determined to ﬁnd a high, warm spot on land in which to
deposit about a dozen eggs. 
    In lieu of the once vast linear tidewater beaches and sand dunes, driveways and mulch beds are
usually warmer and higher than the surrounding landscape. To maternal terrapins gravid with eggs,
these high points appear to be the ideal nesting ground. Mulch beds have been known to produce a
healthy hatch of an entire clutch; driveways, not so much. 
    Relocation of terrapin eggs from driveways or high traﬃc areas to more hospitable nest sites is
possible. (The Terrapin Institute can help with the relocation procedure and protecting nests from
predators.) 
    After hatching in August or after overwintering and emerging in March/April, roadside ditches may
provide a substitute pathway to the nearest tidal marsh, which hatchlings seem to prefer during their
first two or three years. 
    Patience with these wayward wanderers will be rewarded many fold. Terrapins and other turtle
species may appear clumsy, disoriented, and of little utility, but clearly these animals know a thing or
two about survival. They are the Iron Man of the animal kingdom, having persisted for over 230 million
years on just about every continent. Turtle tips on survival may come in handy for us higher order,
more complicated beings. 
    Terrapins may be a younger turtle species, but they enjoyed these tidal shores long before mankind;
their populations ﬂourished with few natural predators; they have withstood near annihilation,
recovered, and adapted to major impediments in habitats.   Provided we don’t wipe them out
altogether, terrapins may prove to be among the few land-based wild species that can actually adapt
and cohabitate with us. Turtles in general, and terrapins in particular, may allow us to crack the code
on our own medical mysteries, especially in geriatrics and infectious diseases, but only if there are
abundant numbers of various turtle species in the wild. 
    In addition to protecting natural shoreline habitat and helping turtles cross the road, residents are
urged to use a by-catch reduction device (BRD) in all crab pots set in shallow waters. By-catch
reduction devices have been required since 1999, but the regulatory agencies have been cash strapped
and unable to promote the BRD among new tidewater residents. (The Terrapin Institute is available to
help with this requirement.) 
    The Mid-Shore and Talbot County in particular oﬀer some of the best conditions in which to observe
terrapins and study the evolving habits of these ancient creatures and many other wildlife interactions.
First, there is a relative abundance of terrapins in the Choptank and Miles rivers and Eastern Bay of
Talbot County. Second, a substantial degree of naturally occurring tidewater habitat remains intact.
Third, and most important, there seems to be an inherent and profound conservation ethic among core
residents, which in turn has allowed for a realistic perspective on future growth, sustainability, and
restoration. There seems to be a heightened awareness for protecting nature where it naturally exists
instead of merely replacing one natural habitat for another and calling it ecological restoration. 
    For a private conservation organization like the Terrapin Institute and Research Consortium, Inc., this
area seems to be the right place to be. Our new permanent research station in the Bay Hundred area
puts us closer to our reason to be and among those with similar goals and objectives. The Terrapin
Institute plans to be open to visitors on weekends from noon to 4 p.m. and upon request otherwise. The
terrapin research station will open oﬃcially May 9, when we will celebrate Diamondback Terrapin Day
(May 13) and Chesa-Preakness (the Saturday before the Preakness Race). There will also be a terrapin
display and crab pot BRD retroﬁt at the Neavitt Community Flea Market on June 13. If we may help you
to learn more about the diamondback terrapin, other turtle species, and ways to preserve the vital
tidewater habitats of this area we all love so much, please call the Terrapin Institute at 410-745-8359. 
    This turtle has taught us to be tolerant and persistent, qualities we wish for in our children and in our
friends. Through this species we’ve observed residents new to the area become deeply aware of their
footprint and conservation capacity. This species has become the Face of Restoration, and what an
adorable face it is.
   Sidebar: Terrapins have been selected to illustrate an educational video on climate change for middle
school students. A U. S. Fish and Wildlife Service videographer recently visited Talbot County to capture
the terrapin in its tidewater splendor; the footage will be available soon on the Internet. Check in later
