An Endangered Breed
As early as 1789, the Spanish controlled the export of ewes from the provinces of New Mexico to maintain
breeding stock. But in the 1850's thousands of Churro were trailed west to supply the California Gold Rush.
Most of the remaining Churro of the Hispanic ranches were crossed with fine wool rams to supply the demand
of garment wool caused by the increased population and the Civil War. Concurrently, in 1863, the U.S. Army
"improvements" and stock reductions were imposed by U.S. agencies upon the Navajo flocks. True survivors
were to be found only in isolated villages in Northern New Mexico and in remote canyons of the Navajo Indian
Restorations of the Breed
In the 1970's several individuals began acquiring Churro phenotypes with the purpose of preserving the breed
and revitalizing Navajo and Hispanic flocks. Criteria for the breed had been established from data collected for
three decades by the Southwestern Range and Sheep Breeding Laboratory at Fort Wingate, New Mexico.
Several flocks have developed, and the Navajo Sheep Project has introduced cooperative breeding programs
in some Navajo and Hispanic flocks.
The Dine’ were initially responsible for saving the "old type" sheep from extinction. Navajos successfully
maintained original flocks in isolated areas where no other sheep breeds were introduced. Sheep meat, milk
for yogurt and wool for textiles sustained the Dine’ for centuries. Even today, "Sheep is life," is a strong belief
in traditional Navajos.
In 1934 the U.S. Department of Agriculture established the Southwestern Sheep Breeding Laboratory at Ft.
Wingate, New Mexico to determine what sheep might thrive in that region. They assembled some "original old-
type" Navajo sheep from local flocks and for 30 years introduced fine wool breeds and long wool breeds. They
concluded that the best wool for the weavers and the sheep most suitable for the high desert were the "old
By 1977, the "old type" Navajo sheep had dwindled to less than 500 head so Dr. Lyle McNeal formed the
Navajo Sheep Project to revitalize this breed and keep it from further depletion. Through the efforts of
individuals such as Ingrid Painter, Dr. McNeal, Antonio Manzanares, Maria Varela, Goldtooth Begay, Dr. Annie
Dodge Wauneka, Milton Bluehouse and Connie Taylor with the assistance of conservancies such as the CS
Fund and American Livestock Breed Conservancy and Ganados del Valle, the Navajo-Churro Sheep
Association was formed in 1986. There are currently over 4,500 sheep registered with the N-CSA, an
estimated 1,500 on the Navajo Reservation and several hundred undocumented sheep in the U.S., Canada
Breed standards were developed for conformation and wool characteristics using historic records, oral
descriptions from Navajo Elders, the contemporary Spanish churra and research from the Ft.Wingate project.
This included objective measurements by USDA scientists and subjective observations of the samplers woven
and dyed by Navajo weavers employed at Ft. Wingate. Individual breeders located sheep sifted from the
remnant flocks of the Southwest and West Coast and a few sheep still existed at UC Davis in California.
"Wanted Posters" were used by Dr. McNeal’s Navajo Sheep Project to increase awareness of the breed and to
locate old type sheep for a revitalization of the nearly extinct breed. Historic standards were applied to the
existing nucleus of all the "old type" sheep that were located.
In 1986, the N-CSA began registering Navajo-Churro based on phenotype. The registry process is vital to
maintaining standards and providing breeders a network of pedigree information. Even though standards are
used, there is an attempt to maintain the diversity within this landrace population. Each sheep registered must
be "seen" and approved by on site inspection or by mail in photos and fleece samples. All progeny must be
inspected for registration, even if parents are registered. The inspectors must have competence in sheep and
wool. Several on the team are university professors or County Extension Agents who specialize in sheep. The
flock book remains open to all conforming sheep even if they lack pedigree information.
Inbreeding is not a problem except in a few flocks. Committed breeders pay attention and share transportation
expense to long haul stock. Genetic relationships for 2,845 sheep were calculated by Harvey Blackburn, U.S.D.
A. to calculate inbreeding levels for individuals and for flocks. The average for the population was 3.8% in
three generations and increasing. A few flocks had levels of 10.5%. Breeders often refer to "A Conservation
Breeding Handbook" by ALBC for advice on sound breeding schemes for small populations.
