Acropora vaughani

Acropora vaughani is a stony coral belonging to the family Acroporidae, one of the most diverse groups of reef-building corals. Like other Acropora species, it forms a calcium carbonate skeleton that provides the physical structure of reef ecosystems, offering habitat and shelter for fish, invertebrates, and other marine organisms. Colonies grow in branching formations, expanding through the deposition of new skeletal material by their polyps, which capture plankton and derive additional energy from symbiotic algae (zooxanthellae) living in their tissues.

This species occurs in marine neritic waters—shallow, nutrient-influenced zones near coastlines—across parts of the Indo-Pacific, with recorded populations in Australia, China, and Japan.

Acropora vaughani is classified as Endangered, with a decreasing population trend. It faces a wide array of ongoing pressures, including fishing and harvesting activities that damage reef structures, recreational activities such as diving and boating, and pollution from domestic wastewater and agricultural runoff, which degrade water quality. Disease and competition from invasive or problematic native species further stress colonies, while habitat alteration, storms, flooding, and even terrestrial fire and fire suppression practices in adjacent catchments contribute cumulative harm.

As a branching coral, it is also particularly vulnerable to physical breakage and bleaching events linked to warming seas.

Conservation efforts for Acropora species generally include marine protected area designations, water quality regulation, restrictions on harmful fishing practices, and coral restoration projects involving fragment propagation and outplanting. Regional monitoring programs track reef health across its range countries.

Given the breadth and persistence of threats affecting its habitat, the species' outlook remains concerning, with continued population decline expected unless water quality and reef management measures are substantially strengthened.
