MR 5 Grey and harbour seal density maps
Grey and harbour seal density maps
[symple_toggle title=”Summary”]
This report describes seal density maps, produced by the Sea Mammal Research Unit, University of St Andrews as a deliverable of Scottish Government Marine Mammal Scientific Support Research Programme MMSS/001/11. The report outlines how the maps can be interpreted and the extent of their limitations with a set of caveats. Appendix 1 describes methodology and software used.
Grey seal (Halichoerus grypus) telemetry data from 1991-2011 and harbour seal (Phoca vitulina) telemetry data from 1991-2012 were combined with count data from 1988-2012 to produce UK-wide maps by species of estimated density and associated confidence intervals. The usage maps are available for download as GIS shape files from the Marine Scotland Interactive website (http://www.scotland.gov.uk/Topics/marine/science/MSInteractive/Themes).
