Threat Vessel strike: Continuing growth in shipping and recreational boating increases the potential for vessel strikes on wildlife. Surface-breathing animals are most at risk but the impact would not be discernible at the ecosystem level. Vessel waste discharge: Increases in vessel traffic will mean there is likely to be more vessel-based waste discharge in the future. Effects on biodiversity are anticipated to be minor under current management arrangements. Wildlife disturbance: Projected increases in population and a continuation of current increases in recreational vessel ownership, particularly in southern and central areas, are likely to lead to an increase in disturbance of wildlife from the presence of boats, snorkelling and diving activities and access to islands. The increase may cause some localised effects, for example on nesting seabirds.
