Forests of Australia 2018B

Forests of Australia (2018) is a continental spatial dataset of forest extent,\r\nby national forest categories and types, assembled for Australia's State of\r\nthe Forests Report 2018. It was developed from multiple forest, vegetation\r\nand land cover data inputs, including contributions from Australian, state\r\nand territory government agencies and external sources.\r\nA forest is defined in this dataset as "An area, incorporating all living and\r\nnon-living components, that is dominated by trees having usually a single\r\nstem and a mature or potentially mature stand height exceeding two metres\r\nand with existing or potential crown cover of overstorey strata about equal\r\nto or greater than 20 per cent. This includes Australia's diverse native\r\nforests and plantations, regardless of age. It is also sufficiently broad to\r\nencompass areas of trees that are sometimes described as woodlands".\r\nThe dataset was compiled by the Australian Bureau of Agricultural and\r\nResource Economics and Sciences (ABARES) for the National Forest\r\nInventory (NFI), a collaborative partnership between the Australian and\r\nstate and territory governments. The role of the NFI is to collate, integrate\r\nand communicate information on Australia's forests. State and territory\r\ngovernment agencies collect forest data using independent methods and\r\nat varying scales or resolutions. The NFI applies a national classification to\r\nstate and territory data to allow seamless integration of these datasets.\r\nMultiple independent sources of external data are used to fill data gaps\r\nand improve the quality of the final dataset.\r\nThe NFI classifies forests into three national forest categories (Native\r\nforest, Commercial plantation, and Other forest) and then into various\r\nforest types. Commercial plantations presented in this dataset were\r\nsourced from the National Plantation Inventory (NPI) spatial dataset\r\n(2016), also produced by ABARES. Another dataset produced by ABARES,\r\nthe Catchment scale Land Use and Management (CLUM) dataset (2016),\r\nwas used to identify and mask out land uses that are inappropriate to map\r\nas forest.

澳大利亚森林数据集（2018）是一份覆盖全大陆的空间数据集，包含森林范围、国家森林类别及类型信息，为《2018年澳大利亚森林状况报告》编制而成。该数据集整合了多种森林、植被及土地覆盖数据输入，包括澳大利亚联邦、州及领地政府机构与外部来源提供的资料。

本数据集对森林的定义为："包含所有生物与非生物组分的区域，以通常具有单一主干、成熟或潜在成熟林分高度超过2米、且上层林冠现有或潜在覆盖度约等于或大于20%的树木为主。" 该定义涵盖澳大利亚多样的原生森林与人工林（无论树龄），其范围亦足够宽泛，可包含有时被称为林地的树木区域。

该数据集由澳大利亚农业与资源经济科学局（ABARES）为国家森林清查（NFI）编制——NFI是澳大利亚联邦与州及领地政府间的合作伙伴关系。NFI的职能是整理、整合并传播澳大利亚森林相关信息。各州及领地政府机构采用独立方法、在不同尺度或分辨率下收集森林数据；NFI则对这些州级与领地级数据应用国家分类标准，以实现数据集的无缝整合。此外，还利用多个独立外部数据源填补数据空白，提升最终数据集的质量。

NFI将森林分为三类国家森林类别（原生森林、商品人工林及其他森林），并进一步细分为多种森林类型。本数据集中的商品人工林数据来源于ABARES编制的国家人工林清查（NPI）空间数据集（2016）；此外，ABARES编制的流域尺度土地利用与管理（CLUM）数据集（2016）被用于识别并掩膜掉不适宜归类为森林的土地利用类型。
