"Proyecto Tagua”
a Conservation Action Program for the endangered Chacoan
Peccary in Paraguay.
Forward by Mike Quick, Curator of
Mammals.
One
of the rarest mammal species in our zoological collection is
the Chacoan peccary or Tagua as they are referred in native
Guarani language. The Chacoan peccary was first encountered
by non-Paraguayan field biologists in 1972 and reported in
1975 by Dr. Ralph Wetzel. The species is considered
“Seriously threatened or endangered” by the IUCN/SSC Pigs,
Peccaries and Hippos Specialist Group and IUCN red list
considers them “Endangered”. Dr. Kurt Bernischke of the
San Diego Zoological Society established the first
in-situ captive breeding colony of peccaries in 1985
with funds provided by SDZS and the Lincoln Park Zoo. The
colony suffered high mortalities in the years following it
inception. By 1992 the herd had grown to 44 animals the
majority of which were born in captivity. In 1996 a mixed
group of 10 animals were imported into the United States
from the Paraguayan colony. The current North American SSP
population is derived from this import. All animals
currently managed by the SSP are the property of the country
of Paraguay.
The Chacoan peccary SSP was developed
in the early 1980’s with only the animals located in
captivity at the Proyecto Taguá in Paraguay. This was the
first SSP to manage an in-situ population without
animals in North American zoological collections. There are
less than 50 animals outside of their native range and all
are held in North American Zoos. Sedgwick County Zoo is one
of seven institutions to manage this endangered species in
their collection. Here we manage 5 males, maintain the
international studbook and recently acquired the fund to
manage the conservation program in the Paraguayan Chaco.
Description of Proyecto Tagua
adapted from a letter by Dr. Dennis A. Meritt, Jr., Adjunct
Professor, DePaul University and SSP Coordinator Chacoan
Peccary:
The conservation program to manage the
Chacoan peccary or Tagua is located in Paraguay, South
America, in the Chaco at the site known locally as Fortin
Toledo. Toledo is approximately 35 kilometers from the
nearest community with central services. This is Filadelphia,
a Mennonite community. Here one can buy food, water, diesel
fuel, small equipment and supplies, and there are links to
the rest of the world by telephone and sporadically, by
internet. There is a good community hospital, medical care,
dental assistance, two hotels, and several places to eat
regional specialties. Filadelphia has dependable water and
electricity but no sewage system.
Fortin Toledo is less than an hour away
by improved dirt roads from Filadelphia. Here at a rented
estancia are the headquarters of “Projecto Tagua”, the
project to manage the Chacoan peccary in native habitat.
The
estancia is approximately 15 hectares in size. There is a
ranch house with three bedrooms and two full baths, a
storage barn and several smaller out buildings. A small
swimming pool that is currently non-functional serves as a
home to a variety of amphibians during the rainy season.
Electricity is available on a regular basis. Water, however,
is provided by rainwater collected and stored in two
cisterns adjacent to the house. It is then pumped to an
overhead water tower and distributed from that high point.
Availability of water is totally dependent on annual rains.
When there are sufficient rains then there are supplies of
water. When the rainy season is short or fails to come then
supplies are short. In an emergency water can be purchased
locally. Water is a valuable commodity in the Chaco and is
used wisely on a year around basis for washing, bathing and
cooking.
Directly
across from the estancia are a series of large natural
habitat field enclosures used in the management of the
Chacoan peccary colony. There are five large field
enclosures with five smaller isolation pens. Each of these
areas has native vegetation, a shelter to allow animals to
retreat from the elements, a source of water for drinking
and/or bathing, and feeding sites were the animals are
provisioned once daily. At present there are some 32
individuals of both sexes and mixed ages. All animals are in
good health and condition. The lineage of each is known and
recorded. In addition the project is maintaining six
collared peccaries and six white-lipped peccaries, 3 males
and three females of each. Dr Juan Campos, Proyecto Tagua
manager in his doctoral work at Kansas State University’s
School of Anatomy and Physiology, will use these.
Adjacent to the estancia and the
peccary field enclosures is the historic military site the “Trincheras”,
one of the sites of the Bolivian - Paraguayan War in the
1930’s. This is a national monument and is infrequently
visited by dignitaries, military personnel and occasionally
by tourists. Even today remnants of the conflict may be
found in the area of Fortin Toledo and “Proyecto Tagua”,
including bullets, metal fragments, and spent artillery
shells. Several years ago a portion of the Trincheras was
restored by Paraguayan military personnel and the area
fenced to afford it some degree of protection. There are
foot paths through the area to allow visitors a first hand
glimpse of where Paraguayan soldiers spent a significant
portion of their lives during the conflict.
Proyecto Tagua has the full endorsement
and philosophical support of various local, regional and
federal organizations and entities in Paraguay. These
include the leaders of the Mennonite community of
Filadelphia, the Governor of the State of Boqueron where the
project is located, that of the wildlife authorities at
Fauna Silvestre, SENACSA, the equivalent of our US
Department of Agriculture, and the Ministry of the
Environment among others. It has received endorsement from
the regional office of World Wildlife Fund and the
Paraguayan conservation organization, the Moises Bertoni
Foundation. The project is well known and widely respected.
Financial support comes solely from donor funds raised in
the United States by the AZA - Species Survival Plan Species
Coordinator for the Chacoan peccary.
Since its inception in the mid-1980’s
various studies have been conducted related to the Chacoan
peccary and its natural history. A range of publications
have resulted that detailed these studies including those
related to reproduction, nutrition, pathology, behavior, and
immobilization. In the 1990’s the project undertook a field
survey to try to determine relative numbers of Tagua in
nature in the area of its former habitat. More recently an
analysis of breeding results, including litter size,
survivability and sex ratio of offspring was published.
Initiated informally during the same
time were observations of the various forms of animals
present in the area on a seasonal or year around basis.
These have included observations of birds, reptiles and
amphibians and mammals. The area in and around Proyecto
Tagua is rich in biodiversity, both plant and animal. It
offers an opportunity to study the natural history and
behavior of a variety of organisms on a long-term basis.
Five years ago a systematic project was
initiated to begin to identify the avian life forms that use
and inhabit the area of Fortin Toledo. Using various
techniques, including the annual capture, measurement,
banding and release of birds, some insights to the
diversity, population numbers, and site faithfulness of bird
life has been obtained. Now in its fifth season, birds are
captured using mist nets, are measured, marked and released.
Each receives an individual leg band uniquely identifying
the individual for recapture studies. Each bird handled and
released carries a numbered aluminum band embossed with the
projects name, “Tagua”. In 2002 during a three week banding
effort more than 1400 individuals were marked and released.
A significant number of recaptures from earlier years have
been recorded.
The opportunity continues for various
studies related to the flora and fauna of the Chaco. A plant
inventory of the area immediately surrounding Toledo needs
to be completed. The area abounds with wildlife ranging from
the Salt Desert Cavy to several species of armadillo.
Geoffroy cats and jaguarundi are not infrequently seen at or
near the project. A range of birds of prey, parrots, rheas,
chachalacas, and several dove species all call Toledo home,
seasonally or year around. During the long rainy season,
especially during late October and into November, dozens of
species of amphibians, frogs and toads, reappear. These
feed, court and reproduce during the time of water
abundance. Literally tens of thousands of amphibians may be
seen and heard during this time in a good year. Much needs
to be done to identify and gain insights to these life
forms. Various species of harmless as well as venomous
snakes may be found around the project, as well as several
species of lizards, including the tegu. Freshwater turtles,
tortoise, and caiman are found at or near Toledo. Each of
these provides various opportunities for study in a range of
scientific disciplines. The site of “Proyecto Tagua” is an
ideal place to conduct various short and long-term
ecological studies.
Due to various family circumstances
which have developed in the past several months, the
estancia and surrounding 15 hectares that is used by
Proyecto Tagua as a rental property may become available for
purchase. While the exact amount that may be required to
obtain this property is at present unknown it is thought to
be somewhere in the neighborhood of US $40,000.00 all
inclusive. This would be a unique opportunity to secure a
site to be used as a Chacoan Center for Ecological Research
and Studies.
For the past ten years, under the
auspices of the Zoological Society of San Diego who managed
SSP solicited donor monies, “Proyecto Tagua” has flourished
and has turned out to be one of the least expensive
conservation action programs anywhere in Latin America. San
Diego can no longer serve as a money manager for the SSP and
its SSP Coordinator. They have decided to focus their
activities elsewhere. This provided the Sedgwick County Zoo
and its staff with the opportunity to assume responsibility
for money management of donor funds and to identify itself
with a successful conservation program in a unique part of
the world, the Chaco of Paraguay. Further, it provides the
special opportunity for staff to undertake additional
studies related to the flora and fauna of the Chaco at
minimal cost in terms of personnel and other resources.
Donor funds to operate “Proyecto Tagua” underwrite the basic
expenses associated with operation of the project. These
include house rental, electricity, diesel fuel, truck
maintenance and insurance, animal food and supplies,
veterinary care and supplies, personnel costs, and food
allowance for the manager and his assistant. Current annual
expenses, completely covered by donor funds to this point,
total approximately US $35,000.00 for the operation of
“Proyecto Tagua”.
This unique environment and its
specially adapted life forms is found no where else in the
world. The Chaco continues to be impacted by the presence of
human activity but there is still time to make a difference.
Except for the AZA – SSP conservation program for Chacoan
peccary there is no other action program committed to the
Chaco and its biodiversity. The area in and around
“Proyecto Tagua” at Fortin Toledo can provide the Sedgwick
County Zoo and its staff with the opportunity to actively
participate in a conservation action program for a
critically endangered species, the Chacoan peccary,
Catagonus wagneri. Additionally, the continued presence of
conservation activities at the site allows informal as well
as formal education opportunities for a range of audiences
whether casual tourists, the citizens of Paraguay or
residents of Filadelphia. Historically, the Sedgwick County
zoo and its staff have been contributors to conservation
activities in Paraguay including, but not restricted to
animal management, training, zoo assistance, interpretation
and education. The recent acquisition and management of
donor SSP funds for the Proyecto and the SSP Coordinator
continue to confirm our commitment to this region and its
wildlife. Future consideration will be given to exploring
the possibility of developing a Chaco Center for Ecological
Research and Studies at the project site. |
