AbstrAct .—Arabian falconry creates a significant demand for falcons that is met through cap - tive-breeding and wild-take. In relation to wild-take, the convention on International trade in Endangered (cItEs) currently only allows the international trade of one important fal - conry species, the saker ( Falco cherrug ), and this trade is effectively limited to one source country, Mongolia. Market demand for wild-sourced saker Falcons is greater than can be supplied by Mongolia alone; consequently there is also an illegal, unregulated trade in this species along with the ( Falcon rusticolus ) and ( F. peregrinus ). the vast majority of these falcons are sourced from Asian countries. We describe recent advances in the develop - ment of a program in Mongolia that uses artificial nests to create a demonstrably sustainable har - vest of saker Falcons for the Arabian falcon trade. the development of a credible sustainable harvest requires a sound biological basis, a transparent system of monitoring, recording and report - ing together with a strong regulatory framework. the potential conservation benefits of such a system, together with the potential for developing legal, sustainable harvests in other countries for different falcon species, are discussed.

THE MONGOLIAN SAKER FALCON TRADE falcons were illegally trapped in Mongolia each year, but it is thought to number at least the capture and international sale of saker 300 per annum (Zahler et al. 2004). Falcons in Mongolia began after the 1990 Democratic revolution, during a period of Mongolia has exported an average of 286 economic and social upheaval following the saker Falcons per year over the last decade collapse of the soviet union.
