Seagrass meadows: pan-regional species (e.g. Halophila spp. and Halodule spp.)

This map shows the connectivity of Seagrass meadows: pan-regional species (e.g. Halophila spp. and Halodule spp.) in the Great Barrier Reef and its surrounding areas: Torres Strait, Coral Sea and Great Sandy regions. The arrows indicate the strength and nature of the connection between the regions. This map is intended to identify where one region is dependent on a neighbouring region.

Additional notes: Most connectivity is characterised as passive dispersal. It is heavily dependent on oceanography, especially in second half of year. Seed dispersal is also assisted by dugong movement, but this is mostly restricted to within regions, except may be Great Sandy to Southern GBR and Torres Strait and far northern GBR.

The data for this map was developed based on expert opinion (Catherine Collier, Len McKenzie, Paul Marshall).
