Associação Transumância e Natureza (ATN) is a non profit environmental NGO, created in 2000, at Figueira de Castelo Rodrigo, Guarda District, in the northeastern part of Portugal.
The name comes from an international foudation (Transhumance and Nature Foundation), which was one of the founders. The name is a reference to the extinct activity of transhumance  - an old tradition of shepherds, who conducted the herds of sheep a long way, in order to take advantage of pasture land at different altitudes and times of the year.
