In terms of the number of pure Finn sheep imported, the trial was large-scale. It was started in 1979 by the Libyan Agriculture Research Centre which imported 450 pure Finn ewes and 50 rams from Finland. The flock was raised pure on a farm near El-Marg city in a big agriculture project named "El-gabal El-Akhdar" or Green Hill. The area is relatively of high elevation and has mild weather as compared to the severe desert conditions around.
Soon after the arrival of the flock it faced many difficulties including health problems and poor adaptation. The big flock diminished drastically and the trial was terminated completely within two years.
