Other habitat-forming intertidal biota
Intertidal community dominated by habitat-forming fauna such as bryozoans, sponges, tubeworms, crinoids and/or ascidians.
Disclaimer: Ecosystem type descriptions are based on biophysical attributes identified in Central Queensland through expert advice and supported by scientific literature. Not all ecosystem types are mapped based on current inventory, and many of the ecosystems described here may also occur in other parts of Queensland.
Intertidal community dominated by habitat-forming fauna on any type of substrate (i.e. unassigned), and also consolidated substrates of carbonate platform, rock base, pavement or boulders, or intermediate coffee rock. Communities are dominated by biota other than seagrass, macroalgae, mangroves, saltmarsh, corals, oysters and barnacles, and typically include a low density, high species diversity mixed community of fauna, such as sponges, ascidians, crinoids, tubeworms and/or bryozoans, that is, reefal gardens not dominated by hard or soft coral.
Reefal gardens can provide substantial habitat for mobile fauna, such as fishes, in an otherwise structure-less environment.

Substantially under-mapped due to lack of inventory.
Depending on the consolidation, this ecosystem usually occurs as a co-type of other ecosystems, at low densities, including:
