Sea turtle population/mortality monitoring is carried out at several sites along
the Baja California peninsula and in the states of Sonora, Sinaloa and
Michoacán. Local teams implement monthly in-water mark-recapture programs,
survey index beaches for stranded sea turtles, and document evidence of sea
turtle poaching/consumption in their communities. These monitoring surveys allow
us to quantitatively track changes in juvenile turtle populations on
developmental sites, numbers of nesting females at rookeries (in partnership
with several existing long-term projects) as well as the success of our efforts
to reduce threats to sea turtles (poaching and bycatch). In order for this
project to be successful, community members must be trained to carry out the
monitoring and all results must be analyzed and shared with our partner research
organizations. The Grupo Tortuguero coordinator visits each monitoring site four
to six times a year, offering the community teams continuous training and
support.

Bahia de los Angeles
Currently, this is the only sea turtle monitoring site associated with the Grupo Tortuguero in the state of Baja California Norte. The Bahía de Los Ángeles (known also as "LA Bay") is on the Sea of Cortez, and is currently a foraging ground for various species of sea turtle, including the olive ridley and black sea turtles.
In 2005, students from a local High School were involved in a monitoring project meant to determine the reactions of sea turtles to different colored LED lights in the waters. They observed that while red and white lights seemed to have little or no effect, all the species of sea turtle in their study reacted with curiosity to green and blue lights. They recommend that whenever possible, white be used for fishing in sea turtle populated zones, avoiding placing green or blue on nets and lures.

Laugna Ojo de Liebre
Located in the Vizcaíno Biosphere Reserve, this 14 sq. mile lagoon was one of the first sites to monitor sea turtles under the banner of the Grupo Tortuguero and their first year saw 36 captures, of which sadly only 2 were the famed 'caguama' (Loggerhead) turtle. By 2005 having increased community participation in the project, they were able to tag and measure 149 turtles!
Laguna Ojo de Liebre is one of the premiere spots on the peninsula for gray whale watching. The gray whales stop here during their yearly roundtrip migration between their breeding and calving sites along the Baja California Peninsula, and their fridgid arctic feeding grounds in the Bering Sea off the coast of Alaska. To read more about the gray whale, visit Pro Peninsula's Did You Know archive.
Most significant was that the most recent monitoring yielded the largest and heaviest turtles since the project began, which suggests that sea turtles are surviving longer, thus increasing their chances of reaching reproductive moaturity and contributing to population recovery. It is a sign of success for the Grupo Tortuguero, which continuest to strive to help the ancient sea turtle populations of the world continue to thrive for years to come.

Laguna San Ignacio
Located in the Vizcaino Biosphere Reserve on the Pacific coast
of Baja California Sur, is characterized by wide canals 19 to 45 feet deep, with
an abundance of seaweed and eelgrass, and mangroves spanning much of the
coastline.
Laguna San Ignacio is most well known for being home to the most exciting
gray whale watching in the world. Renowned for their friendliness and curiosity,
Laguna San Ignacio's gray whale calves are famous for coming up to the small
'pangas,' and nuzzling up to enthralled spectators as their mothers
encouragingly push them up towards the boat. Although no one can explain this
amazing behavior with scientific certainty, one theory is that due to the small
area of the lagoon (6.7 sq miles), the whales gain confidence in numbers and are
more comfortable approaching humans.
In their first monitoring year of 2001, the Laguna San Ignacio monitoring
team had a modest capture total of 11 turtles. However, in 2002 their results
exploded, tagging 96 turtles with only 7 re-captures. Although 2005 saw their
rates drop to 43 turtles, with 5 re-captures, they were able to interact with
international students from Boston, sharing with them the ecological importance
of marine turtles to the peninsula.

Punta Abreojos
The monitoring site at Punta Abreojos is located in the Estero Coyote, a small uninhabited coastal lagoon. The area is biologically similar to Laguna San Ignacio, covered in sea grass and seaweed. Very little boat or human traffic disturbs the area, making it relatively pristine and unexploited, an excellent opportunity to study the sea turtles that inhabit the peninsula.
In their first year, they were able to capture 164 sea turtles, going down to 163 in their second year. In 2005, the local community project was only able to capture and tag 84 turtles, a significant reduction from years past. However, the study carried out by Grupo Tortuguero in the same site managed to capture and tag 187 sea turtles, pointing to the possibility that sea turtle populations are still keeping steady in the area.

Mulege
A small fishing town on the Sea of Cortez, Mulege has for years
had the desire and willingness to participate in the Grupo Tortuguero's
monitoring program, protect the nests that have been sighted in the area, and to
help prevent poaching and by-catch. Despite ample support and available
resources from the Grupo Tortuguero, the community has had constant difficulties
acquiring the permits required to do the monitorings; however, they continue to
work diligently through an nascent educational program, where participants go on
excursions through the bay, do beach clean-ups, and other activities that
promote appreciation for the sea turtles and the environment in general.

Loreto
The monitoring site in the Bay of Loreto is located in the Loreto Bay National Park on the Sea of Cortez in Baja California Sur, and was created by presidential decree in 1996.
Loreto has participated in sea turtle monitorings with the Grupo Tortuguero almost since its inception, and in fact it was on a small beach just south of town that the Grupo Tortuguero captured and tagged one of its first turtles. Despite a couple of early years of few captures, monitorings have picked back up in 2006, and so far they've captured 2 black turtles, one on the March 31 and one on April 27; both were in good health and weighed 55 and 121 pounds respectively.
Additionally, the local Grupo Ecologista Antares [Antares Ecology Group] (GEA) focuses its efforts on enforcement, education and outreach, as well as managing the situation of dwindling nests due to coastal transformations brought about by hurricane Marty. In a large part thanks to their efforts, 2004 saw a significant increase in sea turtle sightings and a reduction in sea turtle by-catch.
Most importnatly, much of the Grupo Tortuguero's work would not be possible without the support of the community of Loreto, which has been the host to the Anual GT meeting for nearly a decade. During the 8th Anual Meeting, the people of Loreto received the prestigious Don Manuel Orantes Prize from the Grupo Tortuguero in recognition of their tireless efforts towards helping the group thrive and expand, to the benefit of the environmental movement on the peninsula.

Puerto A. Lopez Mateos
The town of Puerto Adolfo López Mateos, located on the Pacific coast of the peninsula, is unique in all the world, due to the presence of a channel that runs between the peninsula and a series of long narrow islands that run parallel to the mainland. This geography creates the only place in the world where one can see gray whales just a few feet away while standing out on the wooden dock where local fishermen and whale guides moore their boats.
The long islands also offer an excellent opportunity to monitor sea turtle mortality by surveying the long stretches of sandy beach where dead turtles tend to wash up. In 2005, the local monitoring group shockingly found 1'108 dead sea turtles on San Lázaro beach; 982 of them were loggerheads.
Much more encouraging are the community developments that have taken place in Lopez Mateos. In conjunction with Proyecto Caguama, the Grupo Tortuguero has carried out numerous educational events in the community, as well as lively festivals celebrating the turtle as part of the people's culture and identity. During the last few years, Lopez Mateos has seen a drastic reduction in turtle consumption, poaching and by-catch, as well as a rise in the use of responsible fishing techniques on behalf of local fishermen.

San Carlos
The Grupo Tortuguero included this monitoring site (the same
site and team as the community of Puerto Magdalena) within its broad research
project of 2005, having captured and tagged 132 turtles. This site is
extremely important to the work of the Grupo Tortuguero, being that in 2005 at
least one of each of all five species of sea turtles that inhabit the
peninsula were spotted there, the most common of them being the black sea
turtle. Between 2003 and 2004 they was only able to tag 14 turtles, 4 of them
being recaptures, and also found 216 dead sea turtles in the area, mostly from
human consumption on holidays and other celebrations. This is relatively low
when compared to 2001 and 2002, when 44 and 36 turtles were captured
respectivley.
Members from the San Carlos and Bahía Magdalena monitoring teams are also
involved in a brand new organization (born in July of 2005) known as Vigilantes de
Bahía Magdalena (Magdalena Baykeeper). This group, headed by Julio Solís, is
dedicated to surveying water quality in the bay at various points, and creating
awareness in the local community about water quality issues. Their work is
sanctioned by the International Waterkeeper Alliance, in support of one of the
10 most important wetlands areas in North America, as well as a vital calving
site for the Pacific Gray Whale.

Pescadero
In a situation similar to that of Mulege, until now monitoring
has been dificult in the community of Pescadero due to a difficulty in acquiring permits.
Until now, they have only been able to carry out nest spotting, which in 2005
totalled more than 100. Moreover, they have attempted to hide said nests in
order to avoid poaching. They have however reported an important fall in turtle
meat and egg consumption in the local community, but assert that there is a need
for more outreach and education.

San José del Cabo
San José del Cabo is a few miles away from the popular tourist destinaton of Cabo San Lucas. The kind of tourism activity that takes place in the area is one of the largest threats to local sea turtles, as sea turtle nests are threatened by horses and vehicles, or simply by the presence of human traffic.
During their 3 years of work in the area, ASUPMATOMA (Asociación Sudcaliforniana de Protección al Medio Ambiente y a la Tortuga Marina [Southcalifornian Association for the Protection of the Environment and Marine Turtles]) has protected 88% of the nests they've found, releasing a total of 18'113 hatchlings. In addition, they are currently working closely with 18 different hotel companies and 100 important members of the local community in order to promote continuing protection of sea turtles.
Another highlight within the community is the Don Manuel Orantes turtle camp, named after the pioneer of sea turtle conservation in the Baja California peninsula. Children are invited to participate in educational activities, as well as releasing turtle hatchings and helping them find their way to the ocean. The program has a firm belief that we must begin educating and involving children today, if we wish them to create a better world for tomorrow.

Cabo Pulmo
Cabo Pulmo is currently a Natural Protected Area located almost
on the tip of the Baja California Peninsula, on the Sea of Cortez. Not only an
important ecosystem for leatherback and olive ridley nests, Cabo Pulmo National
Park is one of the most biodiverse ecosystems in the entire continent. It is
home to 236 species of fish, as well as a stop for the Pacific Gray Whale, the
Whale Shark and many other animals. Furthermore, Cabo Pulmo holds one of the
three only living coral reefs in all of North America, and the only one on the
peninsula.
Between 2005 and 2006, ACCP (Amigos para la
Conservación de Cabo Pulmo [Friends for the Protection of Cabo Pulmo]) carried
out monitoring projects mainly on the sea turtle nesting beaches and involving
more than 70 local youth. 64 nests were found, 48 of them were successfully
protected, although 24 had to be relocated. Their work resulted in 4'590
hatchlings being safely released.

Desemboque
Known also as the Comcaac Nation, the indigenous community of the Seri in the Mexican state of Sonora have a long and deep seated cultural relationship with the leatherback turtle (Dermochelys coriacea) in particular, traditionally viewing the animal as the guardian of their people. Working together with the Grupo Tortuguero, Seri leaders have made efforts to educate their community about the current plight of the leatherback turtle, bringing about a profound cultural transformation. They are developing the belief that it is now the Seri people's time to return the favor to their ancient guardians by becoming their protectors.
The Seri monitor sites at both Desemboque and Punta Chueca, and have been studying the sea turtles in their waters for 5 years. In 2004 they were able to capture and measure 45 sea turtles, 43 of them black and 2 of them hawksbill. In 2005, the Seri community of Punta Chueca jointly received the Grupo Tortuguero's Don Manuel Orantes prize with the community of Colola, Michoacán in recognition of their efforts towards preserving Baja's Black sea turtles.
One of the Grupo Tortuguero's largest support organizations, Pro Peninsula, collaborated with the Seri people to carry out a traditional Seri Leatherback Turtle Release Ceremony, such as hadn't been held since 1981. During the 4 day event, Seri eldress Cleotilde Morales passed on an important part of her cultural heritage, keeping alive the appreciation and connection between the Seri and the leatherback. If you'd like to view photographs of the ceremony, please visit the Grupo Tortuguero's Photo Gallery, or Pro Peninsula's Photo Gallery. |

Mazatlan
Active for almost 30 years, the Mazatlan Aquarium in the Mexican state of Sinaloa runs a program for sea turtle nesting protection that also boasts a broad and in-depth environmental education program, promoting an appreciation of Mexico's natural and cultural patrimony, as well as an integrative perspective of the environment, including it as an important part of society and human life. During their 30 years of existance, they have touched the lives of 2'900 individuals, and protected 1'455 nests, 137'778 eggs, releasing approximately 94'000 hatchlings.
In addition to the nesting program in Mazatlán, the municipality of Guasave under the CIICIR (Interdisciplinary Center for Investigation on Integrated Regional Development) of Sinaloa is one of the most recent additions to the monitoring work of the Grupo Tortuguero. Since their induction, they've engaged in numerous educational and outreach activities, including 15 two session workshops on sea turtle biology and conservation, which included outings to find beached turtles, and witness mother turtles laying their eggs on the local beaches. At one point, participants found a beached olive ridely turtle that had suffered injuries to it's posterior fins, and was severely dehydrated; the turtle (nicknamed 'Singa') was taken to the CIIDIR of Sinaloa for rehabilitation, and was successfully released 4 months later. In addition, the children of the community participated in the Mazatlan Aquarium's annual youth conference, further integrating themselves into the work of the Grupo Tortuguero. The group plans on starting in-water sea turtle monitoring on May 6th of 2006.

Colola
The community of Colola very recently added itself to the work of the Grupo Tortuguero. In the municipality of Coire Opio in the Mexican state of Michoacan, the indigenous community of Colola has begun to promote the sustainable use of the three species of sea turtle that nest on its beaches: the leatherback, olive ridley and black turtles.
Throughout 2005, they patrolled a 3 mile long beach, watching for and tagging turtles during 24 hour stretches. As a result, they were able to protect a total of 3'300 incubated turtle nests, totalling 259'320 eggs, most of them black sea turtles. When added to the nest totals not under incubation which were nonetheless monitered and protected, a grand total of 235'202 hatchlings were released. When added to their total of 235'059 released hatchlings from 2004, the indigenous community of Colola has contributed to the work of the Grupo Tortuguero by protecting 470'264 sea turtles.
In addition to their sea turtle project, the people of Colola are committed to developing their community as per the sustainable development law of Mexico, improving their quality of life, rescuing indigenous culture, and building an ecotourism program that supports and promotes the protection and appreciation of marine turtles. In 2005, the community of Colola jointly received the Grupo Tortuguero's Don Manuel Orantes prize with the community of Punta Chueca, of the Seri of Sonora, in recognition of their efforts towards preserving Mexico's Black sea turtles. They also participated in the Seri Leatherback Release Ceremony held in February of 2005, a solemn tradition that hadn't been seen since 1981. |

Agua Verde
The port of Agua Verde is located about 40 miles south of Loreto. In September of 2005, Niparajá volunteers and staff began monthly in-water sea turtle monitorings.
The initial coordinates chosen for monitoring in Agua Verde yielded only one small 14 pound hawksbill turtle in the first several months. In the month of May of 2006, Niparajá finally decided to change to a site just north of Agua Verde known as La Brecha, frequented by poachers to hunt for turtles. From May to August, 4 black turtles were captured and measured, indicating that this site will likely provide better results. The group of volunteers also works in the community to raise awareness about protecting sea turtles and the environment.
It is believed that this is a seasonal site for sea turtles as they move from one feeding ground to another, and the majority of turtles have been observed during the spring and summer months; it is crucial to continue monitoring to verify this theory.

El Pardito
El Pardito is a small island located between the islands of San José and San Francisquito, about 70 miles from Baja California Sur's capital city of La Paz.
With the help of Niparajá, local fishermen began in-water sea turtle monitoring in El Pardito in September of 2005. During 11 months of active monitoring, they've captured 60 turtles, all of which were measured, tagged, photographed, and re-released into the ocean. Having obtained only one re-capture during this time, it is possible that El Pardito is only a transitory destination for sea turtles, and not a premanent feeding ground such as the coastal lagoons of the peninsula's Pacific coast.
Many local fishermen have reported seeing the increasingly rare hawksbill turtles, of which they managed to capture one during the past year, the rest of their captures being black turtles.

Agua Blanca
Recently incorporated into the Grupo Tortuguero, the community of Agua Blanca currently carries out both monitoring and nest protection projects. Their studies focus mainly on the effects of changes in temperature on nest incubation. They also participate in tagging turtles that they find along the beach, and have found that from 2000-2001 they sighted 16 nesting females, only 2 in 2002-2003, 6 in 2003-2004, and only 1 in 2004-2005. Evidently, there has been a drastic drop in nesting sea turtle numbers at the site.
Agua Blanca was also the site of the first Seri Leatherback Release Ceremony in over twenty years. In collaboration with Pro Peninsula and SEMARNAT, the Grupo Tortuguero helped Seri eldress Cleotilde Morales perform the sobering 4 day ceremony, passing on an important tradition to the next generation of sea turtle conservationists, the Seri youth. If you'd like to see pictures of the ceremony, please visit the Grupo Tortuguero's Photo Gallery, or Pro Peninsula's Photo Gallery.

San Cristobal
Located near to the town of Todos Santos, Punta San Cristóbal is
an important nesting site for the olive ridley turtle.
Part of the Programa Golfina under ASUPMATOMA
(Asociación Sudcaliforniana por la Protección del Medio Ambiente y de la Tortuga
Marina [Southcalifornian Asociation for the Protection of the Environment and
Marine Turtles]), sea turtle monitoring takes place along a 13.5 miles of
nesting beaches. The nest protection project has encouraging results. In 2005 a
total of 326 nests were protected, including 34'887 eggs and 25'075 hatchlings.
Moreover, 37 turtles were captured and tagged along the beaches, and only 9 dead
turtles were found on the coast.
