Halophila minor is a widespread species. It is threatened locally by coastal development and reduced water quality in some regions, but these are not thought to be causing serious declines on a global scale. This species is thought by some to be a synonym with H. ovata. Research on the taxonomy is recommended for this species. This species is listed as Least Concern.
|Range Description:||Halophila minor has an Indo-Pacific distribution. In the Pacific, it is found from southern Japan to Taiwan and Hainan Island (China) as well as southern Viet Nam and throughout Southeast Asia and the Philippines, the Caroline and Northern Mariana Islands. It also occurs in the Torres Straits through the Great Barrier Reef of Australia, New Caledonia and Vanuatu. In the Indian Ocean, it occurs on the east coast of Africa from Kenya through northern Mozambique.|

|Population:||There is no population information for this species. The population status is unknown.|
|Habitat and Ecology:||
This species is ephemeral with rapid turn-over and high seed set, and it is well adapted to high levels of disturbance.
This species normally grows on coral sand or muddy sand together with H. ovalis or with other tropical seagrasses in shallow water. It also extends into deeper water down to seven m where it forms sparse patches with other species such as Halodule pinifolia (Kuo et al. 2006).
|Major Threat(s):||This species is threatened by coastal development and changes in shoreline land-use. It is also affected by water quality from sedimentation, trawling and mechanical damage from boats. These are local threats and are not thought to be causing serious declines on a global scale.|
|Conservation Actions:||There are no species conservation measures for this species. Research on the taxonomy of this species is recommended.|
