AAS_4158_POA_ANNUA_Ecology
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
This data set contains data on the ecology of Poa annua on Macquarie Island collected over a 3 year period. It contains information on the longevity of plants (Longevity), morphology of the plants and how plants allocate biomass to the different plant components (Biomass) and vegetation surveys describing the plant communities Poa annua inhabits. The sites used in this study were distributed across an altitudinal and Poa annua density gradient and are described in the spread sheet (study sites).
Poa annua is an invasive species to Macquarie Island.
Purpose
This data set was collected as part of a PhD project studying the ecology and control of Poa annua on Macquarie Island in order to inform management of invasive species in the sub-Antarctic.
