The distribution of Osilinus lineatus (Monodonta lineata) (Da Costa) at its eastern English Channel limit in 2004
Author & date of last revision: admin on 20 November 2011
Populations of Osilinus lineatus, on Isle of Portland and east Dorset shores have been assessed for the year 2004. The numbers recorded for sites between Portland Harbour and White Nothe indicate a significant increase in population size in recent years. Comparison with populations recorded before the 1963 winter shows that the sparse populations of that time are now represented by only those east of White Nothe. Western Ledges in Portland Harbour support a thriving, apparently breeding, population.
