Important marine mammal area
Important Marine Mammal Areas (IMMAs) were formulated by the Marine Mammal Protected Areas Task Force (MMPATF), a joint initiative created in 2013 by the International Committee on Marine Mammal Protected Areas (ICMMPA), the International Union for Conservation of Nature’s (IUCN) World Commission on Protected Areas (WCPA) Marine Vice Chair, and members of the IUCN Species Survival Commission (SSC). The IMMAs are defined as "discrete portions of habitat, important to marine mammal species, that have the potential to be delineated and managed for conservation".
