Parameters of Poultry Breeds on ALBC Conservation
Priority List (2010)
Poultry breeds on the ALBC Conservation Priority List generally
conform to certain genetic and numerical parameters.
1. The breed is from one of the four traditional
U.S. poultry species (chickens, ducks, geese, and turkeys).
2. A bantam breed may be listed if there is no large
3. The breed census satisfies numerical guidelines:
- Critical: Fewer than 500 breeding birds in the United
States, with five or fewer primary breeding flocks (50 birds or
more), and estimated global population less than 1,000.
- Threatened: Fewer than 1,000 breeding birds in the United
States, with seven or fewer primary breeding flocks, and estimated global population less than 5,000.
- Watch: Fewer than 5,000 breeding birds in the United
States, with ten or fewer primary breeding flocks, and estimated global population less than 10,000. Also included are breeds with genetic or numerical
concerns or limited geographic distribution.
- Recovering: Breeds that were once listed in another category
and have exceeded Watch category numbers but are still in need
- Study: Breeds that are of interest but either lack definition
or lack genetic or historical documentation.
4. The breed is a true genetic breed (when mated
together, it reproduces the breed type.)
5. The breed has had an established and continuously
breeding population in North America since 1925. Or, if imported
or developed since 1925,
- The foundation stock is no longer available.
- Must meet numeric guidelines for inclusion.
- Must have at least five breeders in different locations in
the United States.
- The global population is threatened and the United States population
is making a contribution to conservation of the breed.
Breeds not meeting all these criteria may be placed in the "Study" category
Conservation categories are based on the estimated number of
breeding birds, males and females, and the number of breeding flocks.
Given the vulnerability of poultry to predators, the number of flocks
is important. "Conservation breeding flocks" are those
of 50 birds and above.
