Table A - Identification of populations/breeds
Table B - Identification of stocks in need of conservation.
(see Section 3.4)
For all breeds identified in table A above and not found in larger numbers in neighbouring countries.
Table C - Critical Populations
Immediate action is needed to prevent extinction.
Table C1 - Critical Live Population
A live animal conservation project must be established.
Objectives
To increase the population size as rapidly as possible to at least an effective population size (Ne) of 50.
To maximize the genetic influence of all the founder animals.
To minimize the loss of heterozygosity due to inbreeding, drift and selection.
To use the conservation herds to monitor and characterize the breed.
Methods
Sample as much of the population as possible. Ideally all animals should be included.
Breeding groups should be as small as possible and at different locations to reduce the risk of disease.
Each individual animal should contribute equally to the next generation, mating groups of one male : one female with each male being replaced by one son and each female by one daughter.
Selection should only be against gross abnormalities.
Table D - Endangered Population
Action to conserve is needed to prevent further erosion of the genetic variation found within the population.
Table D1 - Endangered Live Population
(See Section 4.4)
Objectives
To increase the population size and maintain it on an effective population size (Ne) of no less than 500 animals.
To minimize the loss of heterozygosity due to inbreeding, drift and selection.
To use the conservation herds to monitor and characterize the breed.
Methods
A well planned conservation herd should be established and/or a programme to co-ordinate the farmers and institutions already using this breed.
Selection should be against gross abnormalities and to maintain the breeds known characteristics.
Table E - Insecure Populations
Action is needed to evaluate the breed and prevent substantial loss of genetic variation.
