Citizen science reveals seal site variability on a regional scale
Monitored by amazing CSG volunteers
Previous publications have provided a short term snapshot of seal information over localised areas (Steven, 1935; Davies 1957; Smith, 1966; Summers, 1974; Prime, 1985; T. Leeney et al, 2010)
Cornwall Seal Groups research aims to add breadth (spatially and temporally) and depth (in terms of detail about age/sex; land/sea habitat use and inter/intra annual variation) to demonstrate the variability of sites and their usage by seals
To gain this insight, fragmented coastal sites across the SW peninsular of England were monitored by a large number of local, volunteer citizen scientists, surveying their own patch regularly over a sustained period of time.
Such an understanding of habitat use, by which seals and when, is essential for effective conservation
Way more seals use these sites than implied by the max counts
(E.g. 832 IDs at West Cornwall in 2013)
Seals move through these sites with seasonally repeated patterns
