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.

本数据集为一份Shapefile格式文件，用于划定长棘海星（Crown-of-Thorns Starfish, COTS）初始爆发区，以支撑监测、灭杀及减少农业径流相关投入效益的评估工作。
该长棘海星划定框为长棘海星首次爆发的推测性分布区域。本多边形覆盖北至蜥蜴岛（Lizard Island）、南至绿岛（Green Island）的区域。

制作方法：
本多边形通过ArcMap软件手绘生成，绘制要求为覆盖绿岛至蜥蜴岛以北全部珊瑚礁，且不得切割任何珊瑚礁体。北侧边界设置于蜥蜴岛以北区域，以纳入宁芙岛（Nymph Island），原因在于1996-2000年长棘海星初始爆发期内，该礁体的长棘海星爆发程度与蜥蜴岛相近。

数据格式：
仅含1个多边形且无属性字段的Shapefile文件。
