This dataset is a collection of vegetation surveys across a series of non-random sites on Macquarie Island. Vascular plant species cover was recorded in quadrats during the summer of 2017/2018. This is vegetation surveys undertaken on Macquarie Island at sites of key ecological interests, as part of AAS 4305Species cover of vascular plants, bare ground and bryophytes is documented for each quadrat. There were three different observers. Invertebrates were sampled at invertebrate site, skuas at skua site, burrowing petrel sites includes sites where burrowing petrels were absentThe data contains the following fields:Unique quadrat identifierLatitude of site centroidLongitude of site centroidquadrat: Quadrat number at each sitearea: Quadrat area size either: 1m2 or 100m2shape: Quadrat shape either: square or circleGPSacc Whether GPS coords relates to site (y) or general area (n)date: Date of surveyobs: Data collection by: Melissa Houghton (MH), Toby Travers (TT) or Jez Bird (JB)Study site: Describes the motivation behind the site selection. species: Species, taxonomic group or ground featurecover: Cover class: 0 (not present), 1 (less than 5%), 2 (5-25%), 3 (25-50%), 4 (50-75%), 5 (75-100%)peat_depth: Peat Depth (m)veg_height: Vegetation height (m)
