What's here
Each card is one kind of habitat. Under it, each official type's own area here, from its own map or model and year, so you can see then and now. Areas are never added together. A dashed name is PLOT's proposal for where a type belongs.

Next step · proposed
Confirm whether the 2007 Jawbone Marine Sanctuary management plan is still current
- Barrier. Several claims here rest on a 2007 plan. Parks Victoria's page says the plan directs management until reviewed, but does not say whether a review has happened or is planned.
- Proposed action. Ask Parks Victoria whether the 2007 plan (and the 2007 Management Statement for the Flora and Fauna Reserve) has been reviewed or replaced.
- Done when. A dated statement from Parks Victoria on the plan's status is linked as a source.

Next step · proposed
Link Jawbone Marine Sanctuary's reef and seagrass monitoring results
- Barrier. Parks Victoria describes ongoing reef and community seagrass monitoring at the sanctuary, but no dated results were found, so PLOT can describe the sanctuary's habitats but not their condition or change.
- Proposed action. Ask Parks Victoria for its latest intertidal and subtidal reef monitoring reports and any Sea Search seagrass records for the sanctuary, and add them as sources.
- Dated monitoring results with methods are linked as sources, or Parks Victoria confirms none are published.

What PLOT looked for and didn't find
No water-quality testing sites within the sanctuary (as stated in 2007)
Parks Victoria's 2007 plan states that EPA Victoria monitors water quality in Port Phillip but has no testing sites within the sanctuary. This pilot did not find a more recent statement either way.
What would close it: Current EPA Victoria (or other) water-quality sampling sites and dated results covering the sanctuary, with methods.
Reef and seagrass monitoring results not located
Parks Victoria describes ongoing intertidal and shallow subtidal reef monitoring and community seagrass (Sea Search) and fish (Reef Watch) monitoring, but this pilot did not locate published, dated results.
