Extraction of mammals - Seal hunting (HOLAS 2)

Short description

This dataset is built from the following Human activities dataset: • Hunting of seals The number of hunted seals (see separate metadata on hunting of seals) were averaged over 2011-2014 separately for grey seals, ringed seals and harbour seals (e.g. number of hunted grey seals / year). In Sweden the numbers of hunted grey seals in 2011 (74) were reported for the whole Swedish territorial waters), but here the numbers were set only to Swedish Gulf of Bothnia, as corresponding numbers were reported there in 2013 (75) and 2014 (65). The area of the reporting unit was used to calculate the number of hunted seals / km2 and the data was converted to 1km x 1km grid. For the Baltic Sea Impact Index, the values were normalized. Normalized value 0.5 was set to the level of quota for hunting of seal species in the Baltic Sea. The following quotas for hunting were used: Grey seal: 2000, Ringed seal: 350, Harbour seal 230.

Lineage

Data source: Data reported by HELCOM Contracting Parties. See separate fact sheet on hunting of seals. Data quality: Datasets used to build the layer include numbers of hunted seal, reported for different units in different countries (counties, territorial waters). Due to differences in the reporting units, the accuracy of the data varies across the Baltic Sea. Seal hunting not reported for all countries. Attribute information: Raster value representing number of hunted seals in the hunting district in relation to hunting quota. Spatial coverage: Entire Baltic Sea. Spatial resolution: Original data reported for counties and territorial waters, depending on country. Here 1 km x 1 km grid.
