Fifty-one Kemp’s ridley
nests, containing 4,805 eggs, were found on Texas beaches during 2005.
Twenty-nine were located on North Padre Island [including 28 at Padre Island
National Seashore (NS)], seven on Galveston Island, one on Matagorda
Peninsula, three on Matagorda Island, two on Mustang Island, six on South
Padre Island, and three on Boca Chica Beach. Only three other Kemp’s ridley
nests have been confirmed in the United States during 2005, including one in
Georgia and two in Florida. |
 |
More Kemp’s ridley nests
were found in Texas during 2005 than in any other year since record keeping
began. The previous record of 42 nests was set in 2004. Additionally, the 28
nests found at Padre Island NS exceed the previous record of 23 nests found
there in 2002. |
 |
Eggs
from 41 of the 51 Kemp’s ridley nests were collected for protected incubation
in the turtle laboratory at Padre Island NS. From these 41 nests, 2,647 Kemp’s
ridley hatchlings were released at the park between June and August. An
additional 87 hatchlings were released from a nest that went undetected at egg
laying, but was found hatching in the dunes at Padre Island National
Seashore. An additional 765 Kemp’s ridley hatchlings from 9 nests were
released on South Padre Island. |
 |
Kemp's ridley sea turtles are the most
endangered sea turtles in the world. |
 |
The species' primary nesting site is near
Rancho Nuevo in Mexico. During the 1940's, an estimated 40,000 female Kemp's
ridleys nested on this Mexican beach. During the 1970’s, the number of nesting
Kemp's ridley turtles fell below one thousand. Measures to protect nesting
Kemp’s ridley turtles and their eggs in Mexico began in 1966 and continue
today. |
 |
Kemp’s ridley is a native nester at Padre
Island NS, with nesting records dating back to the 1940’s. |
 |
In 1978, to help preserve the species, an
international, multi-agency, experimental project started at Padre Island NS,
to re-establish a secondary nesting colony of Kemp's ridley turtles. From
1978-1988, 22,507 eggs were transported from Mexico to Padre Island NS for
incubation and imprinting. After exposure to the Padre Island NS sand and
surf, most hatchlings from this effort were reared at the National Marine
Fisheries Service (NMFS) Laboratory for 9-11 months and released into the Gulf
of Mexico. |
 |
Efforts to detect nesting Kemp’s ridley
turtles have been underway at Padre Island NS since 1986. It is vital to
locate nest sites so that the nesting turtles and their eggs are available for
study and protection. Components of the detection effort have included beach
patrols and public education. Other groups also led detection efforts in
other areas of the state. Padre Island NS staff provided training, technical
assistance, and/or guidance to those other programs. |
 |
Documentation to date shows that 13 different
individuals from this project returned to nest in Texas, with a total of 27
nests recorded from these turtles. Additionally, 13 different individuals that
had been taken directly from Mexico as hatchings between 1989 and 1993 and
head-started for 9-11 months at the NMFS Laboratory have also been recorded
producing a total of 15 nests in Texas. |
 |
More confirmed Kemp’s ridley nests have been
found at Padre Island NS than at any other single location in the United
States, making it the most important nesting beach for this species in the
United States. |
 |
Kemp’s ridley turtles nesting at Padre Island
NS include individuals not affiliated with the experimental imprinting or
head-starting projects (i.e. wild turtles), head-started individuals from the
experimental imprinting project, and head-started individuals that had been
taken directly from Mexico as hatchlings. |
 |
Overall, the number of Kemp’s ridley nests
found on the Texas coast has increased during the last decade (1995 - 4 nests,
1996 - 6 nests, 1997 - 9 nests, 1998 - 13 nests, 1999 - 16 nests, 2000 - 12
nests, 2001 - 8 nests, 2002 – 38 nests, 2003 – 19 nests, 2004 - 42 nests, 2005
- 51 nests). |
 |
Hatchlings are about the size of a silver
dollar and are black on top and bottom. |
 |
Adult
Kemp's ridley turtles are olive green on top and creamy white on the bottom,
weigh 80 to 100 pounds, and are approximately 2-1/2 feet in length. |
 |
Kemp's ridley turtles
sexually mature in 10 to 15 years, and seek nesting sites at that time. |
 |
Satellite transmitters were attached to the first four Kemp’s ridley turtles
found nesting at the National Seashore during 2005. This study was initiated
in 1997 and information from it has been used to predict where and when the
turtles might nest again within the nesting season and to aid with nest
detection efforts. Another objective of this study is to gather information
on where the turtles go between and after nesting. |
 |
Various other studies of
the nesting Kemp’s ridley turtles and their eggs continued. |
 |
In addition to the 51 Kemp’s ridley nests
located on the Texas coast during 2005, two loggerhead and four green sea
turtle nests were documented. One of the loggerhead and all four green turtle
nests were found at Padre Island NS and those eggs were transported to the
incubation facility there for protected care. The eggs from the loggerhead
nest found on South Padre Island were transferred to a protective corral
there. |
 |
The
public was invited to attend 10 of the hatchling releases held at the National
Seashore during 2005 and overall over 2,000 people attended. |
 |
Extensive media coverage of the project continued during 2005. On July 29,
the project was featured on an ABC World News Tonight segment in which Dr.
Donna Shaver, Chief of the Division of Sea Turtle Science and Recovery, was
named the “Person of the Week”. |

Community support of the
Kemp’s ridley project reached unprecedented levels during 2005. Nearly 140
volunteers participated in the patrol program at Padre Island NS. The
Beautify Corpus Christi Association, other community groups, and local
representatives spear-headed and funded three significant actions focusing on
Kemp’s ridley and the importance of this area to this endangered species. On
March 16, the 9-foot bronze Kemp’s ridley sculpture entitled “Journey’s End”
by world famous artist Kent Ullberg was unveiled in Ullberg Park on Padre
Island. In the summer, the State of Texas passed a Resolution naming North
Padre Island and Padre Island National Seashore the Sea Turtle Capital of
Texas and stating: “Be it Resolved that North Padre Island be recognized for
its vital role in the conservation of sea turtles in the Gulf of Mexico and
that all those involved in that important work be extended sincere best wishes
for continued success in their endeavors”. Lastly, in November, four 15’x5’
sign bridge panels at the entrance to North Padre Island on the John F.
Kennedy Causeway featuring Kemp’s ridley were painted, providing a lovely
gateway to the island and special reminder to residents and visitors that
Kemp’s ridleys are important inhabitants here. |
