The effects of both water temperature and light levels were tested on two species of seagrass that have different distributional ranges, but which overlap only in the Great Barrier Reef, Australia: Halodule uninervis is a tropical species common throughout the Indo-Pacific and east-African coast, while Zostera muelleri occurs in subtropical and temperate waters of Australia and New Zealand. Disclosure statement. 23, 211–219. Jon C. Day previously worked for the Great Barrier Reef Marine Park Authority between 1986 and 2014, and was one of the Directors at GBRMPA between 1998 and 2014. Declining water quality has led to conditions in which light levels have become the primary limiting factor in many seagrass meadows, and although this tends to have local effects, it is a globally significant problem (Waycott et al. Home Biodiversity Location of the GBR and the threats it is encountering ... Seagrass. Seagrass is also important for carbon sequestration. This reef-bound carbon sink is one of many so-called “Blue Carbon” sinks. The Great Barrier Reef World Heritage Area (GBRWHA) includes one of the world's largest areas of seagrass (35,000 km 2) encompassing approximately 20% of the world's species.Mapping and monitoring programs sponsored by the Australian and Queensland Governments and Queensland Port Authorities have tracked a worrying decrease in abundance and area since 2007.
