Forests of Australia (2018)

**This dataset has been superseded by the *Forests of Australia (2023)*. For further information please see:**\r\nhttps://data.gov.au/data/dataset/forests-of-australia-2023\r\n\r\n*Forests of Australia (2018)* is a continental spatial dataset of forest extent, by national forest categories and types, assembled for *Australia's State of the Forests Report 2018*. It was developed from multiple forest, vegetation and land cover data inputs, \r\n including contributions from Australian, state and territory government agencies and external sources.\r\n\r\nA forest is defined in this dataset as "*An area, incorporating all living and non-living components, that is dominated by trees having usually a single stem and a mature or potentially mature stand height exceeding two metres and with existing or potential crown cover of overstorey strata about equal to or greater than 20 per cent. This includes Australia's diverse native forests and plantations, regardless of age. It is also sufficiently broad to encompass areas of trees that are sometimes described as woodlands*".\r\n\r\nThe dataset was compiled by the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) for the National Forest Inventory (NFI), a collaborative partnership between the Australian and state and territory governments. The role of the NFI is to collate, integrate and communicate information on Australia's forests. State and territory government agencies collect forest data using independent methods and at varying scales or resolutions. The NFI applies a national classification to\r\nstate and territory data to allow seamless integration of these datasets. Multiple independent sources of external data are used to fill data gaps and improve the quality of the final dataset.\r\n\r\nThe NFI classifies forests into three national forest categories (Native forest, Commercial plantation, and Other forest) and then into various forest types. Commercial plantations presented in this dataset were sourced from the National Plantation Inventory (NPI) spatial dataset (2016), also produced by ABARES. Another dataset produced by ABARES, the Catchment scale Land Use and Management (CLUM) dataset (2016), was used to identify and mask out land uses that are inappropriate to map\r\nas forest.\r\n\r\nThe *Forests of Australia (2018)* dataset is produced to fulfil requirements of Australia's *National Forest Policy Statement* and the *Regional Forests Agreement Act 2002* (Cwth), and is used by the Australian Government for domestic and international reporting. \r\n\r\nThis dataset is updated every five years for the Australia's State of the Forests Report Series.

*《澳大利亚森林（2018）》*是一套覆盖全大陆的森林覆盖范围空间数据集，依据国家级森林类别与类型编制，专为《2018年澳大利亚森林状况报告》打造。该数据集整合了多份森林、植被与土地覆盖数据源，其中包括澳大利亚联邦、州及领地政府机构，以及外部来源提供的相关数据。

本数据集对森林的定义为：**"一片包含所有生物与非生物组分的区域，以通常具有单一主干、成熟或潜在成熟株高超过2米，且现有或潜在冠层覆盖度（上层林冠）约等于或大于20%的树木为主导。这一范畴涵盖澳大利亚各类原生森林与人工林，无论其林龄。该定义也足够宽泛，可涵盖有时被称为疏林的树木区域"**。

本数据集由澳大利亚农业与资源经济科学局（Australian Bureau of Agricultural and Resource Economics and Sciences, ABARES）为国家森林清查（National Forest Inventory, NFI）编制，该清查是澳大利亚联邦与州、领地政府间的合作项目。国家森林清查的职责是整合、统一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、以不同尺度或分辨率收集森林数据，国家森林清查则通过统一的国家级分类标准对各州及领地的数据进行处理，以实现这些数据集的无缝整合。此外，研究团队还使用多份独立外部数据源填补数据缺口，提升最终数据集的质量。

国家森林清查将森林划分为三大国家级森林类别（原生林、商用人工林与其他森林），并进一步细分至各类森林类型。本数据集收录的商用人工林数据源自澳大利亚农业与资源经济科学局（ABARES）制作的《2016年国家人工林清查》（National Plantation Inventory, NPI）空间数据集。另有一份由澳大利亚农业与资源经济科学局（ABARES）制作的《2016年流域尺度土地利用与管理》（Catchment scale Land Use and Management, CLUM）数据集，用于识别并掩膜掉不适宜标注为森林的土地利用区域。

《澳大利亚森林（2018）》数据集的编制旨在满足澳大利亚《国家森林政策声明》与《2002年区域森林协定法案（联邦）》（Regional Forests Agreement Act 2002 (Cwth)）的相关要求，被澳大利亚政府用于国内与国际报告工作。

本数据集每五年更新一次，以适配《澳大利亚森林状况报告系列》。更多相关信息可访问澳大利亚森林官网：http://www.agriculture.gov.au/abares/forestsaustralia/sofr/sofr-2018
