Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2008-03-15
Assessor(s): Short, F.T.
Reviewer(s): Livingstone, S., Harwell, H. & Carpenter, K.E.
Justification:
This is a newly described species. There is very little information on this species and it is recommended that research be carried out on its distribution and ecology, and that monitoring of the population is put in place. This species is listed as Data Deficient. There is a possibility that this species may be threatened due to its very restricted distribution.

Habitat and Ecology [top]

Habitat and Ecology: Halophila sulawesii has a similar vegetative appearance as Halophila ovalis, and has been reported as "deep water H. ovalis" in the literature. However, H. ovalis is a dioecious plant while H. sulawesii is a monoecious one, a feature resembling H. capricorni Larkum, that is the presence of a single male or female flower in separate floral axils of the same rhizome (Kuo 2007).  It is also a member of the Halophila decipiens complex.

Halophila sulawesii is found on coral sand between 10 and 30 m and grows adjacent to corals Seriatopora hystrix and Acropora sp. and other seagrasses such as Halophila decipiens and Halodule uninervis.
Systems: Marine

Threats [top]

Major Threat(s): The major threats to Halophila sulawesii are unknown. Possible threats include the degradation of habitat due to sedimentation and siltation from coastal development.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures for H. sulawesii. Research is recommended for the general biology, taxonomy and threats to this species, and additional field studies are needed to investigate its precise distribution and reproductive biology (Kuo 2007).
