An annual scientific monitoring plan for the Dadia national park (Dadia NP) has been implemented by the WWF Greece since 2000 and it includes the monitoring of ecological status of the forest, raptor population, and human and natural factors. Particular emphasis has been given to the Black Vulture, a priority species for conservation according to the EU Birds Directive. In 1979, this species was near extinction with a population of 26 individuals and 6 breeding pairs. Since then with the aid of conservation and feeding support measures, the population increased to 20-22 breeding pairs and a total population of 22 individuals in 1999. This population increase trend did not continue for the period after that and has not been expanded to adjacent regions, raising concerns about the future of the population.
To promote the protection and management of the species, a Management plan for the black vulture in Dadia NP, which evaluates the recent status of the population and proposes measures for the short and long term conservation of the species, was drawn-up in 2002 and started to be implemented in 20031. actions as the study of the movements using radiotelemetry, satellite telemetry and visual marks (rings and patagial tags) are implemented. Moreover, studies for the population’s genetic diversity, the physiological condition and the influence of environmental contaminants on the vultures are included. Marking and sampling of vultures was realized by trapping the vultures in a specific movable cage. In October 2003 and during 7 days, 28 black vultures and 46 griffon vultures were trapped, handed, sampled and released. Radiotracking equipments were set in 7 black vultures from which 6 are still tracked around Dadia NP.
