Forest area as a proportion of total land area

Forest area is sourced from the same Australian publication as that used to inform Australia’s Country Report to the UN FAO Global Forest Resources Assessments (FRA). The FRA will be the ongoing mechanism by which this indicator will be regularly populated. Updates of this indicator occur every 5 years.\r\nThe established Australian forest cover definition used for reporting (no minimum extent, > 2 m height, > 20% canopy cover, irrespective of agricultural usage) differs from the UN methodology, however it is accepted by the UN FAO as suitable to the Australian environmental context.\r\nNote: The UN FAO Global Forest Resources Assessments (FRA) will be the ongoing mechanism by which SDG indicators 15.1.1 and 15.2.1 will be populated after the Voluntary National Review with statistical annex is submitted in 2018. ABARES prepares Australia’s Country Report to the five-yearly FRA, with the next FRA due for release in 2020. Australia’s Country Report is underpinned by data published in the five-yearly series Australia’s State of the Forests Reports published by ABARES and prepared in collaboration with state and territory governments.

森林面积数据的数据源，与澳大利亚为编制提交给联合国粮食及农业组织（United Nations Food and Agriculture Organization, UN FAO）的全球森林资源评估（Global Forest Resources Assessments, FRA）国家报告所采用的数据源一致。全球森林资源评估（FRA）将作为该指标定期更新数据的长效机制，该指标每5年更新一次。
澳大利亚用于报告的既定森林覆盖定义（无最小面积要求、树高大于2米、冠层覆盖率大于20%，不受农业用途限制）与联合国的评估方法存在差异，但联合国粮食及农业组织认可该定义适配澳大利亚的实际环境条件。
注：2018年提交带有统计附件的国家自主审查报告后，联合国粮食及农业组织全球森林资源评估（FRA）将作为可持续发展目标（Sustainable Development Goals, SDG）指标15.1.1与15.2.1的长效数据更新机制。澳大利亚农业与资源经济科学局（Australian Bureau of Agricultural and Resource Economics and Sciences, ABARES）负责编制澳大利亚每五年一届的全球森林资源评估国家报告，下一次全球森林资源评估报告预计于2020年发布。澳大利亚的该国家报告以ABARES发布的五年期系列报告《澳大利亚森林状况报告》的数据为支撑，该系列报告由ABARES联合各州及领地政府共同编制。
