---- Public Summary from Project ----
Australia's World Heritage listed subantarctic Heard and McDonald Islands are experiencing rapid climate change. Their terrestrial and coastal ecosystems are poorly known. This multidisciplinary project will gather baseline data on ecosystem biodiversity and species distribution, and make predictions about responses to future environmental change, providing vital information for conservation protocols.

The download file contains two excel spreadsheets and a pdf copy of the referenced paper.

Three species, Bryoerythrophyllum recurvirostrum, Philonotis cf. tenuis and Syntrichia filaris have been added to the list of moss species known from the island, bringing the total to 40 moss taxa.
