Soil seedbank data for Stellaria media on Macquarie Island. There are 6 files of soil seedbank data for Stellaria media on Macquarie Island. The first 4 files provide the data and methods on the seed burial experiment both in textural and pictorial form whereby seed was buried in nylon mesh bags at 2 depths across 6 sites and then exhumed twice after 1 and 2 years to determine the longevity and viability of buried seed. The 6th file shows the statistical analysis for these results and provides graphs of the data developed in the statistical software package R. File 5 includes seedbank data collected from beneath 6 plants at each of 4 sites whereby soil cores were taken from beneath the plants and then also two distances away (15 and 60 cm) and the seeds counted at various depths. In this way, seed dispersal was measured. More detailed methods are given in each of the files. Seedbank of S. media sampled using 20 random (GPS referenced) 100 mm depth intact cores (60 mm diameter) at 6 infested sites, then transferred in plastic bags to UNE to be characterised. Freshly harvested seeds buried in nylon bags at 6 sites for monitoring of persistence (germinability, viability and dormancy) in later seasons.
