Modelled old-growth forest boundaries.

This layer contains identified areas of modelled old-growth forest derived from both vector and grid based analysis. Areas delineated as old growth forest are identified to meet the Victorian definition of old-growth forest based on a set of modelling criteria, rules and input datasets. The data is not reliable at scales less than 1:100,000 (ie 1:25,000), not all old-growth polygons have been confirmed by field checking and the reliability of the modelled linework has not been verified.

本图层包含通过矢量（vector）与栅格（grid）分析得到的模拟老龄林（old-growth forest）识别区域。被划定为老龄林的区域，需符合基于一系列建模标准、规则及输入数据集所确立的维多利亚州老龄林定义。该数据在比例尺小于1:100000（即1:25000）时可靠性不足，并非所有老龄林多边形要素均已通过野外核查确认，且模拟线划要素的可靠性尚未得到验证。
