Aerial Fire Retardant Avoidance Areas: Terrestrial (Feature Layer)

This layer contains features of aerial fire retardant avoidance areas delivered as part of the 2011 Nationwide Aerial Application of Fire Retardant on National Forest System Land Environmental Impact Statement. This Feature Class shows areas, provided by each National Forest who used aerial fire retardant from 2000-2010, where the aerial application of fire retardant should be avoided in order to prevent the potential of impacts to Federally listed threatened or endangered species as identified through consultation, or Forest Service sensitive species. Data includes location of terrestrial and hydrographic areas where the application of aerial fire retardant is to be avoided. Current aerial fire retardant standards prohibit application within 300 feet of hydrographic features. Therefore, this data may contain duplicate hydrographic areas already covered by existing standards. This data is to be used in planning and implementation phases of USFS fire activities to help prevent misapplication of aerial fire retardant in known areas of TES species or water features throughout National Forest lands. Provided here is a National merged dataset derived from each National Forest contribution. This data has been merged, dissolved, and erased of attributes contained in each original component dataset. For this purpose, specific attributes are not necessary, as any spatial areas depicted simply show areas where aerial fire retardant use is to be avoided as stated in USFS guidelines.

本层包含作为2011年全国空中喷洒阻燃剂环境影响评估的一部分提供的空中阻燃剂避难区域特征。该特征类别展示了2000-2010年间使用空中阻燃剂的各国家森林所提供的区域，其中空中阻燃剂的喷洒应避免，以防止对联邦名录中已确定的受威胁或濒危物种（通过协商确定）或森林服务敏感物种可能产生的影响。数据包括应避免空中阻燃剂喷洒的陆地和水文区域的地理位置。当前空中阻燃剂标准禁止在水文特征300英尺范围内进行喷洒。因此，此数据可能包含已被现有标准覆盖的重复水文区域。此数据用于美国森林服务机构（USFS）火灾活动的规划和实施阶段，以帮助防止在已知的国家森林土地上的受保护物种或水域区域中误用空中阻燃剂。此处提供的是基于各国家森林贡献的全国合并数据集。该数据集已合并、消融并去除了原始组成部分数据集中的属性。为此目的，特定属性并非必需，因为所描绘的任何空间区域仅显示根据美国森林服务机构（USFS）指南应避免使用空中阻燃剂的区域。该记录来源于美国农业部企业数据库存，该库存输入至https://data.gov目录。此记录的数据包括以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService、CSV、Shapefile、GeoJSON。欲获取完整信息，请访问https://data.gov。
