Abstract

Rottnest Island is a marine reserve lying 20 km offshore from Perth, Western Australia. It has a subtropical climate and, due to the south flowing, warm Leeuwin Current, many tropical as well as temperate marine species are found here. Many marine organisms are considered as isolated, at their southernmost extent. The marine reserve is mostly in shallow (less than 20 m depth) water and is made up of the following main habitat categories: sand, seagrass, mixed seagrass and reef, reef, intertidal platform and reef wash. The reef habitat (~ 45%) occupies the largest area, followed by seagrass (21%) and sand (20%) (Rottnest Island Management Plan 2003-2008). The island also has important coral communities, though not extensive in cover. Bathymetry of the waters surrounding Rottnest Island is quite varied, owing to the presence of many submerged limestone formations, favourite spots for divers and snorkellers.
