Macquarie Island vegetation and habitat surveys

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)本数据集为麦夸里岛（Macquarie Island）一系列非随机样地的植被调查汇总。2017/2018年夏季，研究人员于样方内记录了维管植物（vascular plant）物种盖度。 本次调查作为AAS 4305项目的一部分，在麦夸里岛具备关键生态价值的样地开展植被调查工作。本数据集记录了每个样方内的维管植物、裸地及苔藓植物（bryophytes）的盖度。本次调查由3名不同调查人员完成。无脊椎动物采样于无脊椎动物样地，贼鸥（skuas）调查于贼鸥样地，掘穴海燕（burrowing petrel）样地则涵盖了掘穴海燕未出现的样地。 数据集包含以下字段： Unique quadrat identifier：唯一样方标识符 Latitude of site centroid：样地中心点纬度 Longitude of site centroid：样地中心点经度 quadrat：每个样地的样方编号 area：样方面积，可选值为1m²或100m² shape：样方形状，可选值为方形（square）或圆形（circle） GPSacc：GPS坐标关联类型，y代表坐标关联具体样地，n代表坐标关联区域概略范围 date：调查日期 obs：数据采集者，可选为Melissa Houghton（MH）、Toby Travers（TT）或Jez Bird（JB） Study site：描述样地选择的动机 species：物种、分类类群或地表覆盖特征 cover：盖度等级：0（未出现）、1（盖度<5%）、2（5%~25%）、3（25%~50%）、4（50%~75%）、5（75%~100%） peat_depth：泥炭层深度（单位：米） veg_height：植被高度（单位：米）
