State

Very low impact

There are few or negligible impacts from this pressure, and accepted projections indicate that future impacts on the marine environment are likely to be negligible.

Low impact

There are minor impacts from this pressure in some areas, and accepted projections indicate that future impacts on the marine environment are likely to occur, but will be localised.

High impact

The current environmental impacts from this pressure are significantly affecting the values of the region, and projections indicate serious environmental degradation in the marine environment within 50 years if the pressure is not addressed.

Very high impact

The current environmental impacts from this pressure are widespread, irreversibly affecting the marine environment, and projections indicate widespread and serious environmental degradation in the marine environment within 10 years if the pressure is not addressed.
