Characteristics of masticated particles in mixed-conifer forests of the western United States: Field data

This data publication contains the results of field work in masticated materials of mixed-conifer forests in 14 study locations. Mixed-conifer masticated materials were investigated in four states of the western U.S., including Idaho, Colorado, New Mexico, and South Dakota. The data were collected from 2012 through 2016 as part of the MASTIDON project, which was a four-year research project to characterize how burning properties of masticated material are affected when different cutting machines are used to treat the forests and when masticated particles are left on the ground for multiple years to decompose. The project was funded by the Joint Fire Sciences Program (JFSP) and RMRS between 2013 and 2016. The masticated particles within this project were created by four different machines, including a vertical rotating head, horizontal drum, chipper, and mower. They had been decomposing in situ in wet and dry areas of the mixed-conifer forests since their initial treatment. This publication gives GPS locations and laser elevation data for each field site and the GPS locations where depth measurements were taken within each macroplot. It gives depths for each of the five fuel layers distinguished within the masticated materials at two scales. The first scale is at three-meter intervals along each of six transect lines. The second scale is within each microplot and quarter plot where samples were taken from the quarter plots for further lab work. The data also contain estimates of vegetation cover and height at each of the depth-measurement locations.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

本数据发布包含了对14个研究地点混交林咀嚼材料的野外工作结果。在包括爱达荷州、科罗拉多州、新墨西哥州和南达科他州在内的美国西部四个州对混交林咀嚼材料进行了研究。这些数据收集于2012年至2016年期间，作为MASTIDON项目的一部分，该项目是一个为期四年的研究项目，旨在表征使用不同切割机械处理森林以及将咀嚼颗粒留在地面上多年分解时，咀嚼材料的燃烧特性如何受到影响。该项目由2013年至2016年间的联合火灾科学计划（JFSP）和RMRS资助。本项目中的咀嚼颗粒由四种不同的机器创建，包括垂直旋转头、水平鼓、切碎机和割草机。它们自最初处理以来，一直在混交林的湿区和干区原地分解。本出版物提供了每个野外站点的GPS位置和激光高程数据，以及在每个宏观图内进行深度测量的GPS位置。它提供了在两个尺度上区分的五层燃料的深度。第一个尺度是沿每条六条横断面线的三米间隔。第二个尺度是在每个取样于四分图并进行进一步实验室工作的微观图和四分之一图内。数据还包括在每个深度测量位置的植被覆盖率和高度估计。本记录来源于为https://data.gov目录提供数据的美国农业部企业数据目录。本记录的数据包括以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService。欲获取完整信息，请访问https://data.gov。
