Plants
The vegetation on Michaelmas Cay is characteristic of cays found on the outer barrier reef. Low-growing, it consists of beach spinifex, stalky grass, goatsfoot, bulls-head vine, sea purslane and tar vine. Nutrients fertilising the vegetation come from seabird droppings and carcasses. The smaller Upolu Cay is un-vegetated.[1]
Animals
Michaelmas Cay is important as a breeding site for several species of terns. It has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of greater and lesser crested terns.[2] Sooty terns and common noddies also breed there. Other terns that have nested on the cay in the past include roseate and black-naped terns.[3]
Green turtles sometimes nest on the cays. The surrounding reefs have a rich marine fauna, including giant clams.[1]
