Abstract: This Plan proposes strategies and concrete actions for the preservation, recovery, sustainable use and knowledge of the populations of aquatic mammals that inhabit the marine and continental waters of Colombia (South America) in relation to the main threats identified in the national territory. We have structured it around five strategic lines and each of them brings together the lines of action adapted to the needs identified during the construction of this document: (i) research and monitoring; (ii) sustainable management; (iii) information and disclosure; (iv) education, training and participation, and v) a last strategic line focused on political regulations and institutional strengthening.
