Dimension, volume, and biomass data for hand-piled fuels in California and Washington

Land managers and air quality regulators need a tool to accurately and efficiently estimate the biomass and emissions from burning of hand-piled fuels as pile burning becomes a more widespread and common practice for treating high fire hazard areas with surface fuels in excess of desired levels. This data publication contains dimensions, volume, and biomass measurements of hand-constructed piles of different types of debris, with a variety of shapes and sizes, in forest and woodland areas in Washington and California. Study sites include the Sequoia National Forest, Okanogan-Wenatchee National Forest, Whiskeytown National Recreation Area, and the Los Padres National Forest where sample sites were typical of hand-piling operations in the West. Data include measurements, taken in 2008, of 121 hand-constructed piles composed primarily of coniferous (n=63) and shrub/hardwood (n=58) material.Our objective was to quantify the relationships between pile composition, pile size, and pile biomass by measuring and weighing hand-constructed piles composed of different types of debris (i.e., conifer, shrub, and hardwood) with a variety of shapes and sizes.Original metadata date was 05/01/2015.

土地管理者及空气质量监管者亟需一款能够精确且高效估算手持堆积燃料燃烧产生的生物质和排放量的工具，鉴于手持堆积燃料燃烧成为处理地表燃料超出预期水平的高火险区域的一种日益普遍且常见的做法。本数据出版物包含华盛顿州和加利福尼亚州森林和林地不同类型垃圾堆积物的尺寸、体积和生物质测量数据，这些堆积物形态各异，大小不一。研究地点包括塞奎亚国家公园、奥坎根-温奇国家森林、威士忌镇国家休闲区和洛斯帕德雷斯国家森林，其中采样地点典型地反映了西部手持堆积操作的特点。数据包括2008年采集的121个手持构建堆积物的测量数据，这些堆积物主要由针叶树（n=63）和灌木/硬木（n=58）材料构成。我们的目标是通过对由不同类型垃圾（即针叶、灌木和硬木）构成的，形态和大小各异的堆积物进行测量和称重，量化堆积物组成、堆积物大小和堆积物生物质之间的关系。原始元数据日期为2015年5月1日，于2016年12月15日进行了少量元数据更新。
