This GIS dataset holds positive records from the National Otter Survey of Ireland 1980/1981 by the Vincent Wildlife Trust. The survey was the first systematic study of otters and their wetland and coastal habitats to be undertaken throughout the Republic of Ireland and Northern Ireland. It took place between January 1980 and March 1981. The survey provided a base-line against which further studies could be compared and thus assist monitoring of populations and distribution.
