Abstract

In response to the strategic plan required by the Agricultural Act of 2014, the USDA Forest Service Forest Inventory and Analysis (FIA) program is initiating a strategic inventory of the nation’s urban forests. The inventory is designed to provide timely and credible data on urban forests, thereby meeting an expanding need for information on trees located in communities where more than 80% of people live. The program monitors the status and trends of trees in urban settings (i.e., urban forests), enabling assessment of their composition and structure, ecosystem services and values, health, and risk from pests and disease. At full implementation with funding, resources, and partnerships in place, the program as designed would provide annual updates of urban forest conditions on approximately 68 million acres of land and for 100 of the most populous cities in the United States. The traditional forestland inventory of FIA continues and is complemented by the new urban inventory providing the means for a more complete assessment of the tree and forest resources across the United States.

美国国家战略性城市森林清单

摘要

为了响应《 2014年农业法》所要求的战略计划，USDA森林服务森林清单和分析（FIA）计划正在开始对美国城市森林进行战略清单。该清单旨在提供有关城市森林的及时，可靠的数据，从而满足对80％以上人口居住的社区中树木信息的不断增长的需求。该计划监测城市环境（即城市森林）中树木的状况和趋势，从而能够评估树木的组成和结构，生态系统服务和价值，健康状况以及病虫害风险。在资金，资源和伙伴关系到位的充分实施下，该计划的设计将为美国100个人口最多的城市提供约6800万英亩土地的城市森林状况的年度更新。国际汽联的传统林地清单仍在继续，并得到了新的城市清单的补充，这些清单为更全面地评估美国树木和森林资源提供了手段。
