On 15 February 2016 was installed in a culvert on the 114 National road a camera-trapping system adapted to an adjustable stand. This system allows us to assess through videos and photographs what kind of species are able to use this artificial structure to cross this high traffic road. This action had the collaboration of Carlos Martins and João Cuco (Infraestruturas de Portugal [IP], Évora), and Eng. João Morais from Departamento de Estruturas Especiais (IP, Lisboa).
