Scientists Fear for Nesting Turtles

 

May 08, 2006 — By Lynn Brezosky, Associated Press

SOUTH PADRE ISLAND, Texas — Endangered Kemp's ridley sea turtles emerge here

every spring from the Gulf of Mexico, leaving smeary trails of flipper prints

from surf through sand to nests where they lay their eggs.

 

But a planned beach-restoration project could mean vehicles intruding on the

nesting grounds, sand dumped over eggs or new sand obscuring the paths to

turtles' nests.

 

The city is awaiting a decision from the Army Corps of Engineers on a variance

from the Endangered Species Act that would allow the project to begin this month

or next. Officials say the beach erosion caused by tides and last year's

hurricanes is threatening property and needs to be repaired soon.

 

" Probably from a sea turtle standpoint, it's the worst two months of the year to

do it, " said Jeff George, curator of Sea Turtle Inc., South Padre's hospital for

injured sea turtles and a partner with Fish & Wildlife in rescuing turtle eggs.

 

Jody Mays, a biologist for the U.S. Fish and Wildlife Service, and other turtle

experts agreed May and June are the two worst months.

 

" But I don't want to be a tree hugger and say we can't do it, " he said. " We can

help put patrols out there and protect the nests. At the same token, you also

have to say, why do you have to do it in May or June? "

 

If not alleviated soon, the erosion could harm hotels and other properties, said

Catherine Ball, planner for the town of South Padre Island.

 

Ball said the town was prepared to provide some extra hands -- college students

or volunteers -- to help find the turtle nests. Each year biologists collect and

guard the eggs until late summer, when thousands of baby turtles scamper to sea.

Without biologists' intervention, only a few would survive.

 

Without major disturbances, this year promises to be a good one for nest finds.

At least 25 had been discovered on Texas beaches this past week, compared with

five for the same period last year. By the end of April 26, the first day of the

protection project, 10 nests had been found. The eggs will be monitored for the

48- to 62-day incubation period.

 

Once born, the turtles spend their lives at sea, with only females coming on

shore again to nest on the beach where they were hatched.

 

The vast majority of Kemp's ridleys nest on a beach in the Mexican state of

Tamaulipas, just south of Texas.

 

A home movie from 1947 shows about 40,000 nesting there. But the population has

diminished dramatically because eggs were harvested for food or because shrimp

trawls and gill nets trapped and drowned the turtles.

 

Beaches along South Padre and North Padre islands have been less-used nesting

spots, and biologists hope their efforts to protect them will bring more females

and create another major resting ground.

 

The beach on the north end of town, where South Padre's strip of hotels and

high-rise condominiums peters out, has been eroding for many years, said Don

Hockaday of the University of Texas-Pan American Coastal Studies Laboratory.

 

The town usually keeps on top of the problem by using spoils from dredgings of

the ship channel leading to the Port of Brownsville.

 

In January it became clear that Katrina, Rita and other storms from the 2005

hurricane season had dragged so much sand into the channel that ships were in

danger of grounding.

 

The port used took most of its annual dredging budget to remedy that problem,

and the scooped sand was dumped at sea.

 

Unfortunately, South Padre officials realized too late, the winter tides had

been particularly hard on the island and they could have used the sand.

Long-forgotten retaining walls were re-emerging, and dune markers that used to

be 2 feet higher than the beach are now 5 feet higher.

 

The schedule for the next port dredging, which would have begun in early fall,

depends on what happens with the federal budget for 2007.

 

" Right now we need sand, " Ball said. " The erosion is not only taking dunes, it's

lowering the elevation of the beach. "

 

The town has identified another source of sand and has applied for the variance,

which would allow the work to go forward during turtle season, Ball said.
