Furcellaria lumbricalis distribution
Distribution of Furcellaria lumbricalis based on data submission by HELCOM contracting parties. Mainly pointwise occurrences of Furcellaria were submitted, originally gathered in national mapping and monitoring campaigns, or for scientific research purposes. From Estonian waters, a predictive model was used (200m resolution), that was converted to presence/absence using minimized difference threshold (MDT) criteria. For Poland, only confirmed occurrence of Furcellaria were included (Slupsk bansk, Rowy reef and reef at Orlowo cliff). All data (Furcellaria points and the raster presenting predicted presence of Furcellaria) were generalized to 5km x 5km grid cells.

Data source:
Denmark: Point data from national monitoring along (dive and video, points and transects), data from 2007-2015. Data is available through Miljøportalen
Estonia: Modelled distribution of Furcellaria lumbricalis based on observations from national monitoring (dive and drop video), 2005-2014.
Finland: Point data gathered during the national marine mapping programme VELMU (2004-2015) and inventories from Åland Islands.
Germany: Point data originally gathered for monitoring and research purposes (video, photos, dive, wading, snorkeling), data from 2010-2015.
Latvia: Point data of from national monitoring (dive and drop video) campaigns during 2006-2013.
Lithuania: Polygon data on the distribution of Furcellaria.
Poland: Point data digitized based on Polish Marine Atlas and corrected using expert opinion.
Russia: No GIS data reported. Furcellaria occurs in the Kaliningrad region, although not presented on the map.
Sweden: Point data from national monitoring and mapping surveys (1995 -2015) extracted from SMHI SHARK database.
2018 updates: Updated data from Sweden and Finland and new data from Russia were included.
Data quality:
Mapping is not exhaustive and sampling density varies between the countries.
Attribute information: Raster value representing presence (1) or absence (0)
Spatial resolution: 1 km x 1 km grid (originally 5 x 5 km).
