The objective of this publication is to serve as a basis for further conservation work at national and private levels and to raise awareness among all stakeholders. In a country like Greece, with varied topography and climate, one expects great diversity in livestock as a result of their adaptation to these conditions. The book documents information available on one breed/variety of buffalo, 37 of cattle, 13 of chickens, 4 of donkeys, 39 of goats, 20 of horses, 6 of pigs and 46 of sheep, mostly with photos. It lists breeds' risk statuses, based on the following six categories: not at risk, vulnerable, critical, endangered, unknown or extinct. Generally, the category with highest frequency is “unknown” (37%) followed by “endangered” and “critical” (17% each). The proportion of extinct breeds/varieties is highest in cattle (41% of all listed cattle breeds/varieties) while the highest percentages of “unknown” breeds are in chickens (69% of all listed chicken breeds) and goats (68% of all listed goat breeds/varieties). Other information includes official acceptance, population size, colour and other phenotypic traits, performance traits, and area of distribution. Species and breeds within species are arranged in alphabetical order for easy reference. Not all breeds/varieties documented are rare, however. The Karagouniko sheep, for example, has a population of 220 000.
