Dadia Forest in north-eastern Greece is well known for its diversity of breeding birds of prey. In 1980, the area was declared a wildlife reserve. One of the most endangered species at that time was the Black Vulture Aegypius monachus. To help the population of Black Vultures a feeding station was established in 1987. A monitoring programme from 1984 until present indicates that the operation of the feeding station has coincided with an increase in the numbers of Black Vultures wintering in Dadia by nearly threefold, an increase in the number of breeding pairs from 10 to 21, and an increase in breeding success from 40% to a peak of 95%. A slight faltering in the continued rise in the numbers of Black Vultures in Dadia is attributed to a poisoning event in 1995.
