Service Identification
Abstract: In the German EEZ of the North Sea, we distinguished ten benthic communities and six international fishing fleets(averaged over the years 2005-2008). From this we produced spatially explicit estimates of benthic disturbance, which was computed as theratio between relative local mortality by benthic trawling and the recovery potential after a trawl event. Results showed great differences in spatial patterns of benthic disturbance when accounting for different environmental impacts of the respective fleets.Here, the so-called weighted DI is shown, where the largest impact to the searfloor is assigned to large beam trawlers, targeting flatfish,mainly sole.
Purpose: The map illustrates the Disturbance Indicator (DI) of benthic infaunal communities in relation to local fishing pressure. The disturbance indicator is the ratio between mortality induced by a fishing métier and the recovery potential of the prevailing community.

Constraints: The DI is a theoretical approach to the quantification of the risk of benthic trawling. We used a static infaunal community distribution described by Rachor and Nehmer (2003) and built on a previous study by Fock et al. (2011) and references therein, describing the relationships between mortality due to benthic trawling, recovery time and recovery frequency for each community in relation to the typical sediment category inhabited.
