JNCC Management Units for Cetaceans in UK waters (3rd Party Data)
This is a collation of spatial datasets detailing the extent and location of the final agreed Management Units (MUs) for the seven most common cetacean species in UK waters. This dataset is wholly owned by JNCC and Natural Resources Wales (NRW) can access the data through an Open Government Licence. Almost all species of cetacean found in UK waters are part of larger biological populations whose range extends into the waters of other European States and/or the High Seas. Equally, the number of individuals present at any one time may be only a small proportion of those that make use of UK waters throughout the year. In order to obtain the best conservation outcomes for many species, it is necessary to consider the division of populations into smaller management units. Management Units (MUs) should be based on our best understanding of the structure of biological populations and any ecological differentiation within such populations (as outlined in the Appendix). However, the boundaries between MUs may be determined by either political boundaries (e.g. the boundary between Ireland and the UK) or the management of human activities (e.g. ICES divisions used for the collection of fisheries data and management of fisheries). As far as possible, the management units defined in this report have been based on the presence of known populations, with divisions proposed on the basis of ecological evidence and/or divisions used for the management of human activities. Therefore, whilst being consistent with the best biological understanding, an MU refers to the animals of a particular species in a geographical area to which management of human activities is also applied. As such, these MUs comprise partially artificial divisions of often slightly uncertain biological populations.

Each dataset contains the extent of the management units and an estimated abundance and 95% confidence intervals fro the common cetacean species for each of the defined ICES areas. It has been derived from the Inter-Agency Marine Mammal Working Group (IAMMWG), comprising representatives of Natural England (NE), Scottish Natural Heritage (SNH), Natural Resources Wales (NRW) and Joint Nature Conservation Committee (JNCC).
