| One of the most widespread yet manageable pressures imposed on the seabed is that resulting from disturbance of the substrate by towed demersal fishing gear (bottom fishing and dredging). Demersal fishing gears are deployed on every continental shelf in the world and, in UK waters, the footprint of fishing is estimated to account for over 99% of the known footprint of all human pressures on the seabed. It is, therefore, essential that current and future management of fishing activities are based on an improved scientific rationale in order to improve the long-term sustainability of this activity. While the impacts of demersal fishing on the biological characteristics of the seabed have been well-studied, the approaches have tended to focus on assessing... |

| Aim : The speciesarea relationship (SAR) is increasingly being used to set conservation targets for habitat types when designing protected area networks. This approach is transparent and scientifically defensible, but there has been little research on how it is affected by data quality and quantity. Location : English Channel. Methods : We used a macrobenthic dataset containing 1314 sampling points and assigned each point to its associated habitat type. We then used the SAR-based approach and tested whether this was influenced by changes in (i) the number of sampling points used to generate estimates of total species richness for each habitat type; (ii) the nonparametric estimator used to calculate species richness; and (iii) the level of habitat... |
