S1 DATA. Table of proposed management strategies for conserving Antarctic biodiversity to the end of this century, detailing strategy objectives, specific actions that make up the strategy, costs, and feasibility of each action. S2 DATA. Workbook containing the numerical values underlying the figures in the main text and Supporting information. The values for each figure are provided in separate worksheets. These values were calculated from the raw values using the methods described in the “Materials and methods” section of the main text. The cost and feasibility values are available in S1 Data. The averaged expert intactness and benefit values are available on the Australian Antarctic Data Centre: https://doi.org/10.26179/5da8f8e7a2256. S1 TEXT. PDF file containing the supporting figures and tables for “Threat management priorities for conserving Antarctic biodiversity”. File contains Figs A–F and Tables A–N. DATA AVAILABILITY STATEMENT : Antarctic priority threat management database containing intactness values, benefits and uncertainties for each biodiversity taxon are available from the Australian Antarctic Data Centre (AADC; https://DOI.org/10.26179/5da8f8e7a2256). Action, cost and feasibility information, as well as the numerical values underlying the Figures, are included within the paper and its Supporting Information files. Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climate change. Yet no large-scale assessments of threat management strategies exist. Applying a structured participatory approach, we demonstrate that existing conservation efforts are insufficient in a changing world, estimating that 65% (at best 37%, at worst 97%) of native terrestrial taxa and land-associated seabirds are likely to decline by 2100 under current trajectories. Emperor penguins are identified as the most vulnerable taxon, followed by other seabirds and dry soil nematodes. We find that implementing 10 key threat management strategies in parallel, at an estimated present-day ...
