sediments causing localised smothering and or reducing the quality and quantity of light received at the seabed.
Wildlife can be impacted by human presence through either direct impacts, such as vessels colliding with wildlife (known as vessel strike), or indirect impacts, such as changes to the natural behaviour of wildlife such as breeding, feeding or resting.

    2.4.4     Invasive species
Invasive species can be pathogens that cause disease, exotic marine pests or overabundant native species.
Potential sources of invasive species include climate-driven range changes, vessel ballast and bilge water discharge, vessel biofouling and accidental or deliberate transport of species. Shallower water ecosystems and native species are particularly vulnerable to invasive species. They can impact these values directly, through disease, predation or damaging important habitats; and indirectly, through competition with native species for habitat and food.
The long-spined sea urchin, a range-extending native species, commonly behaves as an invasive species by forming large aggregations that transform kelp habitats into urchin barrens. Long-spined sea urchins have been observed on mesophotic reefs in the north-west of Flinders Marine Park and the centre of Beagle Marine Park.
At the time of making this plan, the only known exotic marine species in the network is in Beagle Marine Park, where there are extensive beds of the introduced New Zealand screw shell, which may be altering the preferred habitat of native doughboy scallops.

    2.4.5     Marine pollution
Marine and land-based activities have the potential to result in marine pollution which may impact on marine park values. Pollution includes the emission of noise or light, marine debris (for example, plastics and lost fishing gear) and discharge of oil, noxious substances (including chemicals and heavy metals) or sewage waste. Pollution can be detrimental to marine life, causing contamination of ecosystems and entanglement, or can be ingested by marine species. Noise pollution from anthropogenic sound can disrupt species behaviour and methods of communication.

3.1           Park management overview
Park management is focused on the protection and conservation of values and, depending on zoning providing for ecologically sustainable use of the values. The Director achieves this by undertaking management actions, primarily to minimise the pressures on the values (Figure 3.1). Management actions include prescriptions, that is, the zoning and rules for activities specified in Chapter 4 of this plan. Additionally, other management actions outlined in Section 3.4 of this plan underpin the effective management of the parks.
The Director works closely in partnership with First Nations people, government agencies, marine park users and stakeholders to deliver a range of management actions. This partnership approach is essential to managing the marine parks
