Crossett Experimental Forest site, station Selection logging stands at Crossett Experimental Forest, study of production volume of pine in units of cubicMetersPerHectare on a yearly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters
(Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and
Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest)
to support the collection and analysis of long-term ecological datasets.
The project is a large synthesis effort focused on improving the accessibility
and use of long-term data. At present, there are ~50 state and federally funded
research sites that are participating and contributing to the EcoTrends project,
including all 26 Long-Term Ecological Research (LTER) sites and sites funded by
the USDA Agriculture Research Service (ARS), USDA Forest Service,
US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal
(http://www.ecotrends.info). This web portal enables the continuation of data
compilation and accessibility by users through an interactive web application.
Ongoing data compilation is updated through both manual and automatic
processing as part of the LTER Provenance Aware Synthesis Tracking
Architecture (PASTA). The web portal is a collaboration between the Jornada LTER
and the LTER Network Office. The following dataset from Crossett Experimental Forest (CRO)
contains production volume of pine measurements in cubicMetersPerHectare units
and were aggregated to a yearly timescale.

EcoTrends项目由Debra Peters博士（约尔纳达盆地长期生态研究站（Long-Term Ecological Research, LTER），美国农业部农业研究局约尔纳达实验牧场）与Ariel Lugo博士（卢奎约长期生态研究站（LTER），美国农业部森林服务局卢奎约实验森林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。
该项目是一项大型综合研究计划，核心目标是提升长期生态数据的可获取性与利用效率。目前共有约50个州级及联邦资助的研究站点参与并为EcoTrends项目贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究局（Agricultural Research Service, ARS）、美国农业部森林服务局、美国能源部、美国地质调查局（United States Geological Survey, USGS）与众多高校资助的研究站点。
EcoTrends项目的数据可通过探索型网络门户（http://www.ecotrends.info）获取。该门户依托交互式Web应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究站溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据汇编工作通过手动与自动结合的处理方式完成更新。本网络门户是约尔纳达LTER与LTER网络办公室的合作成果。
本次涉及的Crossett实验森林（Crossett Experimental Forest, CRO）数据集，包含以立方米每公顷（cubicMetersPerHectare）为单位的松树材积测量数据，且已按年时间尺度完成数据聚合。
