Metadata details
AAS_4158_POA_ANNUA_seedbank
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 describes the seed bank dynamics of Poa annua on sub-Antarctic Macquarie Island.
The seed bank dynamics spreadsheet quantifies the density and depth distribution of seeds of Poa annua in soil cores collected on Macquarie Island.
The seed burial spreadsheet quantifies the persistence and viability of seeds of Poa annua buried in seed burial bags on Macquarie Island for up to 2 years at varying depths.
Poa annua is an invasive species to Macquarie Island.
Purpose
This data set forms part of a PhD project studying the ecology and control of invasive Poa annua on sub-Antarctic Macquarie Island.
