Natural Power has updated the Ornithological Cumulative Assessment Model (OCcAM), a seabird mortality tool for the offshore wind industry, which is now a free resource managed by the Offshore Wind Industry Council (OWIC). This version includes assessments for nine seabird species relevant to offshore projects, such as the lesser black-backed gull and northern gannet.

The tool provides biometric parameters and allows users to input bird density data for various development scenarios, enhancing early-stage impact assessments. The update has been endorsed by UK statutory nature conservation bodies (SNCBs). A live demonstration webinar will be held on 25th February to guide users on its application.
