Its objective is to gather information on most mammal species that currently lack specific monitoring programs.\n\nAt present, the MOMAT project operates thanks to volunteer participation. The data collected help improve knowledge about the species included both in the annexes of the Habitats Directive and in the EU Regulation on invasive alien species.\n\nAll the information generated will contribute to future updates of the Atlas and Red Book of Terrestrial Mammals of Spain, facilitating a better understanding of our fauna and supporting more effective decision-making in conservation."},"samplingDescription":{"studyExtent":"Spain","sampling":"Track and sign surveys were used to detect mammals through indirect evidence such as footprints, faeces, burrows, and feeding remains.
