Seedling emergence data for Stellaria media on Macquarie Island. There are 4 files on seedling emergence data for Stellaria media on Macquarie Island. The first 3 files are plot maps showing the locations of the seedling emergence plots at Finch Creek, Gadgets Gully and Island Lake. The last data file includes percentage vegetation cover in 15 plots per site prior to the experiment and then seedling emergence counts 1 and 2 months after 3 treatments were imposed, being either intact vegetation, half the vegetation cleared and all the vegetation cleared. More detailed methods are given in the latter file. In-situ emergence monitored in 10 cleared plots (0.5x0.5m) at each of 3 sites over summer. Ex-situ experiments with and without native plant competition and simulated grazing conducted to identify key processes in the success or otherwise of S. media post herbivore eradication. Live plants (and seeds for backup) brought back to UNE from MI. Bulked soil (for use here and at 6) to a depth of 100 mm, collected from MI as in previous project work.
