COTS Initiation Zone Polygon 2016 (Accelerated Partnership, AIMS)

This dataset corresponds to a shapefile that defines the COTS initiation zone for use in the evaluation of the merit of investment in surveillance and cull and reducing agricultural run off.The COTS box is a speculative area of primary outbreaks of Crown-of-Thorns Starfish.This polygon includes Lizard island to the north and Green Island in the south.Methods:The polygon was drawn free hand in ArcMap based on the requirement to cover all reefs from Green Island to just north of Lizard Island without cutting through any reefs. The northern boundary was chosen just north of Lizard Island to include Nymph island because this reef showed outbreak levels of COTS similar to Lizard Island during the 1996-2000 outbreak initiation period.Format:Shapefile with 1 polygon and no attributes.References:Wooldridge, S.A. and Brodie, J,E.

本数据集为用于评估监测、灭杀及减少农业径流投入效益的长棘海星（Crown-of-Thorns Starfish, COTS）初始暴发区划界的形状文件（shapefile）。该长棘海星划定范围为推测的长棘海星初始暴发潜在区域，此多边形覆盖北至蜥蜴岛（Lizard Island）、南至绿岛（Green Island）的海域。
方法说明：本多边形通过ArcMap手绘绘制，需覆盖绿岛至蜥蜴岛以北的全部珊瑚礁且不切割任意一处礁体。考虑到1996-2000年长棘海星初始暴发期间，宁芙岛（Nymph Island）所在礁体的长棘海星暴发程度与蜥蜴岛相近，因此将北部边界设于蜥蜴岛以北以纳入宁芙岛。
数据格式：本数据集为仅包含1个多边形且无属性字段的形状文件（shapefile）。
