Cedar Creek Ecosystem Science Reserve site, station Old Field 45 at Cedar Creek, study of plant biomass of Cyperus in units of gramsPerSquareMeter 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 Cedar Creek Ecosystem Science Reserve (CDR) contains plant biomass of Cyperus measurements in gramsPerSquareMeter units and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（约拿盆地长期生态研究（Long-Term Ecological Research, LTER）站点，美国农业部农业研究服务局（United States Department of Agriculture-Agricultural Research Service, USDA-ARS）约拿实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究（Long-Term Ecological Research, LTER）站点，美国农业部林业局（United States Department of Agriculture-Forest Service, USDA-FS）卢奎洛实验林）于2004年创立，旨在支持长期生态数据集的收集与分析工作。本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应用效率。目前共有约50个州级及联邦资助的研究站点参与并助力EcoTrends项目，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服务局（United States Department of Agriculture-Agricultural Research Service, USDA-ARS）、美国农业部林业局（United States Department of Agriculture-Forest Service, USDA-FS）、美国能源部（United States Department of Energy, DOE）、美国地质调查局（United States Geological Survey, USGS）及众多高校资助的研究站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户依托交互式网络应用程序，支持用户持续开展数据整合与数据访问工作。作为长期生态研究溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，常态化的数据整合工作通过手动与自动处理相结合的方式完成更新。该网络门户是约拿LTER与LTER网络办公室的合作成果。来自雪松溪生态系统科学保护区（Cedar Creek Ecosystem Science Reserve, CDR）的下述数据集包含以克每平方米（gramsPerSquareMeter）为单位的莎草属（Cyperus）植物生物量测量数据，且已按年度时间尺度进行聚合。
