The animals are walking creatures. In a Walking Encounters/Conference, the walking processes of the animals, the, often, invisible companions of human walkers should be considered. The animals are invisible because they try to avoid the encounter with human beings. What remains from their presence is the footprints they leave on the soil: the animal traces. The proposed walkshop will have as protagonists the invisible walkers: the animals. The animal traces will be explored in a specific area close to Psarades, Prespa, throughout the Encounters/Conference. This area can be named: The Land of Invisible Presences. For seven days the participants will be walking across the Land of Invisible Presences documenting the traces that they detect; the traces will be photographed, registered on the map, creating plaster molds of them. Different periods of the day will be chosen and groups of human walkers will be periodiocally scouting the area for traces. Experts will identify the species that produced them. In that way at the end of the seven days an archive of traces will be created that will include all the various documentations. The main outcome will be a map, both printed and digital, where the position of the traces, the trails of the animals and any other documentation will be recorded. The process will also include the documentation of the footprints of domestic animals, creating a connection between these two parallel words. The process will be under the scientific and ecological guidance and supervision of the Environmental Organization for Wildlife and Nature CALLISTO, and Prespa National Forest. This cooperation will secure that the implementation of the walkshop will not disrupt the habitat of the invisible walkers: the animals.
