We outline a model of the probability of seal movement between different haulout locations and the distance between them. The approach comprises a likelihood-generating dispersal kernel and a probability-generating normalization method. The model is specified to the haulout network used by common seals in the Orkney and Shetland Isles and fitted to inter-colony movement data obtained via satellite telemetry. Model selection indicated that the probability of movement is best modeled as a zero-inflated inverse function of distance. Currently , this work is being generalized and extended spatially, temporally and across species. We discuss how these results can be put to use to define biologically relevant management units for seal populations in the UK.
