| Abstract |
A wind power plant can be the cause of bird collisions during the installation and operational time. Wind power plants comprise the wind turbines themselves, interconnecting cables, transformer stations, and ancillary infrastructure including access roads. Their impacts on birds could be divided in to two categories: direct effects (collision) and indirect (habitat loss, barrier effect, disturbance). Even relatively small increases in mortality rates may be significant for populations of some birds, especially large, long-lived species with generally low annual productivity.
Crete has been characterized as an area with very high wind-energy potential due to its mountainous and rugged terrain and the strong winds that prevail almost throughout the year. The aim of the thesis is the assessment of wind power plants’ effects on vultures and specifically on the population of Griffon Vulture (Gyps fulvus) on the island of Crete. Initially, we did the spatial mapping of existing and planned projects of wind power plants according to the requests submitted to Regulatory Authority for Energy for the region of Crete. Secondly we estimated the theoretical collision risk and the expected mortality of the species based on the number of risk flights. For this reason we used a widely applied collision risk model (BAND) which takes into account the griffons’ morphometric characteristics and volatile behavior as well as the size of each wind power plant and the technical characteristics of wind turbines. The data have been processed in a way that we can make assumptions on the model parameters and the combination of wind power plants’ facilities. Field work took place during February and June (2011, 2012) in order to estimate Griffon’s population number and its fecundity. Finally we appraised population's rate of increase during 1996-2012.
The estimated mortality rate is considered high for this species since it approaches the theoretically acceptable number of deaths for the cretan griffon population but without taking into account any demographic factors. Population Viability Analysis is an essential next step for the assessment of collisions’ effects on the population.
