Some of the main pressures on the environmental value of coasts are described below.
They are barriers to achieving this strategy’s targets, so planning and action will need to find ways to minimise their effects.
Some of the native coastal vegetation is secure on public land but population growth and development will continue to create pressure for clearing at some sites.
In addition, incremental damage to native vegetation from recreation, illegal clearing, vandalism and rubbish dumping are inevitable pressures of increasing resident and visitor populations.
Climate change is expected to expose coasts to:

These pressures increase the possibilities of:
Coastal wetlands are among the most valuable, internationally significant natural assets in this region and highly vulnerable to climate change. Declining freshwater inputs and rising seawater intrusions may degrade and ultimately change coastal wetlands by reducing their size, converting them to dry land or transforming them from (for example) saltmarsh to mangrove swamp.
Invasive weeds and pest animals are major barriers to achieving targets for native vegetation quality along the coast and inland.
Weed invasions compete with native vegetation and damage its ability to provide habitat. Much of the coastal zone has ongoing weed problems that are difficult to control.
These pressures are now well-established. Ongoing control is critical but expensive. It needs to be carefully targeted to maximise its benefits.
Likely targets for control include:
It is expected that a Coastal Action Plan will be developed for the coast of the Port Phillip & Western Port region by the Victorian Government (led by the Central Coastal Board). The plan may generate improved information of existing or new pressures on the environmental values of the coasts and may lead to this section being revised.
A method has been used to determine the current condition of coasts (Method and Condition) and targets have been set for the future (Targets). Lead organisations are committed to achieving these targets (Leadership). Targets and leadership arrangements will be determined in consultation with relevant departments, agencies and delegated land managers. Arrangements are in place to monitor and report on progress and success (Monitoring & reporting).
