Protection inside marine reserves
In the region of the Eastern Pacific there are various marine reserves which offer protection to the species that remain within their limits. The function of these reserves is vital to the conservation of endangered marine fauna and maintenance of the extraordinary value of World Heritage Sites.
Unprotected migratory species
However, marine reserves offer insufficient protection for the conservation of these species. Their nature leads them to cover large distances and to leave the area of the reserves, leaving them open to a large number of threats.
