Montipora floweri

Montipora floweri is a stony coral in the family Acroporidae, forming encrusting to plate-like colonies characteristic of the genus Montipora. Like other scleractinian corals, it relies on symbiotic zooxanthellae for energy and secretes a calcium carbonate skeleton that contributes to reef framework building. Colonies provide structural habitat and refuge for a range of reef-associated invertebrates and fish, supporting broader reef biodiversity.

As a sessile filter- and photo-feeding organism, it is highly sensitive to changes in water quality and surrounding substrate condition.

The species occurs in marine neritic waters within the Indo-Pacific region, with confirmed records from Australia and Palau. It inhabits shallow reef environments typical of the genus, where adequate light penetration supports its symbiotic algae.

Montipora floweri is classified as Endangered, with a decreasing population trend. It faces a broad combination of pressures: harvesting and fishing activity that damages reef structure, recreational use of reef areas, competition or predation from invasive and native pest species, and disease outbreaks. Water quality is further degraded by domestic and urban wastewater discharge, agricultural runoff linked to non-timber crop production, and other unspecified pollution sources.

Habitat shifting and alteration, likely associated with broader environmental change, compounds these stressors by affecting reef stability and coral recruitment.

Conservation attention for this species is largely embedded within regional reef management frameworks in Australia and Palau, including marine protected area networks, water quality regulation, and reef monitoring programs targeting Acroporidae corals generally. Species-specific interventions remain limited.

Given the cumulative and ongoing nature of the threats affecting its habitat, and its narrow environmental tolerances, the species' population trajectory is expected to continue declining unless water quality and reef protection measures are substantially strengthened across its range.
