Macrolgae, commonly called seaweeds, are marine plants that photosynthesize, but reproduce without flowers (seagrasses are an example of a marine flowering plant). Macroalgae are visible to the naked eye (in contrast to microalgae), and generally grow attached to the seabed or reef substrate.

Seagrasses are marine plants found in estuaries, reefs and deep water environments throughout the northeast Australian seascape. They form meadows that provide nutrient-rich habitat for many animals, for example, sea cucumbers, fish, urchins, marine turtles, dugongs, sharks and rays all use seagrass meadows at some time during their life cycle.

Crustose coralline algae (CCA) are a red macroalgae (seaweed) that accumulate calcium carbonate and generally grow as encrusting, pink-colored, veneers over the reef substrate. While often inconspicuous to the casual observer, CCA play a vital role in the maintenance of many coral reef systems.

Coastal she-oaks (Casuarina equisetifolia) are an evergreen tree (6 to 20m high) found on coastal sand dunes, beach fronts in sands alongside estuaries and behind fore-dunes, and on gentle lower hills/headlands. Other common names include beach casuarina, beach she-oak or whistling tree.

Pisonia; or Birdlime Tree (due to the fact that at times nesting birds become covered with the sticky fruits).

On coral cays, pisonia forests are tolerant of temporary saltwater and freshwater inundations and can tolerate full water lenses and waterlogged conditions better than other woody competitors. Pisonia are, however, prone to shed branches during storms; the fallen trees and/or branches sprout and revegetate the damaged forest areas. Pisonia wood is rather weak and soft and decays rapidly after the trees fall.

Barramundi is an iconic species throughout northern Australia and are important for all fishing sectors economically, socially and culturally. Catches of barramundi vary spatially and temporally and can be significantly related to river flow or rainfall and evaporation. Variability in catch probably represents changes in underlying stock abundance linked to environmental drivers.

The Great Barrier Reef (GBR) was listed as a World Heritage Area because of its Outstanding Universal Values. This website highlights the connectivity of these world heritage values between the Great Barrier Reef with the surrounding regions: the Coral Sea, Torres Strait and Hervey bay. Understanding this connectivity highlights the importance of co-management between these neighbouring regions where connectivity is strong.

Environment Australia is tasked with managing the networks of Commonwealth Marine Reserves (CMRs). This is particularly challenging for the CMRs in the remote and poorly known N and NW regions, such as the Oceanic Shoals.

Environment Australia is tasked with managing the networks of Commonwealth Marine Reserves.  This is particularly challenging in the remote and poorly known N and NW regions. Researchers from Australia's NESP Marine Biodiversity Hub's D1 project highlight five key environmental variables that may help predict biodiversity patterns across these regions.

In partnership with the Western Australian Department of Parks and Wildlife, Western Australian Marine Science Institution scientists on the Australian Institute of Marine Science vessel RV Solander recently spent 15 days in the field collecting data to help determine what flatback sea turtles in north-western Australia eat.

Flatback sea turtles (Natator depressus) are endemic to northern Australia and one of only two sea turtle species that are not distributed globally (7 species in total). Nesting occurs only on tropical Australian beaches, many in NW Australia’s remote Kimberley region. Under threat from coastal development, predation from feral animals and climate change, flatbacks are listed as a vulnerable species under the WA Biodiversity Conservation Act 2016 and the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and data deficient by the International Union for Conservation of Nature.
