THE AXIOS FERAL HORSES (2008-2012) The feral horses of Axios’ river are an important part of the regional fauna that additionally attract the tourist’s attention. Due to the modernization of the agriculture the domestic horses of this area were left free, since they were not necessary for the ordinary work in the fields. The horses used to wander around the banks of Axios’ river, where they found fertile ground and shelter to multiply their population, resulting after more than 5 decades in a robust trunk horse, the “Axios horse”, which has a very uniform conformation, medium height and phenotypic characteristics derived mainly from Thessalian, and Pindos ponies (and maybe from Thoroughbreds). However the local farmers complain that the horses damage their cultivations, especially during the periods of the river’s flood, when the horses are moving elsewhere for food and shelter. The Greek Society for the Protection and Preservation of Indigenous breeds of Domestic Animals “AMALTHEIA” executed a “SURVEY REGARDING THE POPULATION AND THE BEHAVIOUR OF AXIOS FERAL HORSES” in 2008 for SAVE FOUNDATION. The Survey was financed from the Greek Ministry of Environment through the Axios – Loudias – Aliakmonas Management Authority. The main aim of this project was to monitor the status of these horses and motivate the local community to accept their existence. Our research activities included count of the total horses’ population and the population of each herd using binoculars, and photo cameras from the ground and from the air with helicopter. Also were monitored the preferred locations where the horses use to gather, mate and reproduce, and were also assessed the social behaviour of these horses within their herds, the age range and sex distribution of the horse population and the rate of their multiplication. The foals and nursing mares and the elderly horses of each herd were counted. The Survey has been continued informally to this day by “AMALTHEIA” in order to monitor any changes in the status of the equine population. Conclusions The total equine population in Axios region in 2008 was 67 individuals, i.e. 34 males, 14 females, 7 of non-identified sex and 12 foals, forming 4 reproductive groups, 1 bachelor group and 3 isolated individuals (1 captured). In the years following the 2008 Survey, the population diminished resulting today in 40 horses i.e. 23 males and 17 mares forming two big distinguished groups. The east bank group included most of the bachelors. The west bank group is still in equilibrium. The area where the horses live is restricted by natural and man-made obstacles (channel, river, fences) and by the expanded edible flora and salted areas. Extended degradation of the natural environment is caused by the existence of illegal farm premises, where considerable number of animals is kept, the old wire fences, and the contamination of the river by garbage. The large population of imported cattle in this area is the main cause of soil deterioration due to overgrazing and depression from their footmarks. Big tractors and trucks entering the area further destroy the environment. However the good nutritional status of the horses throughout the year shows that the deterioration of the pastures mainly affects the cattle, which are multiple in numbers (more than 1700) in comparison with horses. The majority of the equine herds, due to lack of suitable land, are forced to share partly their territories and pastures showing that their population is on critical state, because otherwise each stallion would prefer to keep his herd out of the reach of his competitors. This phenomenon is now more intense than 4 years ago. Unusually large number of carcasses and skeletons of horses and cattle have been founded in the area. The local Veterinary Service has isolated the lethal bacterium Bacillus “anthrax” from some of these carcasses. Due to the outbreak of anthracosis in the livestock of the area, strict sanitary measures should be followed as the burning or deep burying of the cadavers and the vaccination of the ruminants and the equids every spring. Unfortunately, no action has been taking place in the last 5 years. The main causes of death seem to be injuries and the anthracosis. However the main reason for the horse population decrease must be the capture and withdrawal of females from the region. The existence of carnivores (wolves etc.) does not seem to affect significantly the population of the horses. Conclusively, it is vital to follow a rational administration of the Axios Delta region, NOT ONLY because the population of the feral horses is on critical level. The Axios delta is part of a National Park, a Natura 2000 area, protected by the Ramsar convention with 277 species recorded. Amaltheia has proposed the necessary measures to prevent further deterioration of the environment, contamination, decrease of the horses’ numbers and horse migration to cultivated areas. However the situation since 2008 has only changed to the worse. More illegal fences, restriction of the natural habitat of the horses, more carcasses exposed and now due to the rise of fuel prices the river bank forest is in danger. “AMALTHEIA” is committed in the continuation of monitoring the status of the Axios Delta feral horses in order to inform the authorities and provide for their welfare.
