Southern Plains Range Research Station site, station Southern Plains Range Research Station Watershed 1, study of plant biomass of Bouteloua curtipendula 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 Southern Plains Range Research Station (SPR)
contains plant biomass of Bouteloua curtipendula measurements in gramsPerSquareMeter units
and were aggregated to a yearly timescale.

EcoTrends项目由Debra Peters博士（若那盆地长期生态研究站（Long-Term Ecological Research, LTER），美国农业部农业研究局若那实验牧场）与Ariel Lugo博士（卢奎洛长期生态研究站（Long-Term Ecological Research, LTER），美国农业部林务局卢奎洛实验林）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。本项目为大型综合研究工作，核心目标在于提升长期生态数据的可获取性与利用率。目前共有约50个由州政府及联邦政府资助的研究站点参与EcoTrends项目并贡献数据，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（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）及众多高校资助的相关站点。EcoTrends项目的数据集可通过探索性网络门户（http://www.ecotrends.info）获取，该门户依托交互式网络应用，支持用户持续开展数据汇编与数据共享工作。作为LTER溯源感知综合跟踪架构（PASTA）的组成部分，持续开展的数据汇编工作通过人工与自动两种处理方式实现更新。本网络门户由若那LTER站点与LTER网络办公室合作开发。本次提供的南部平原牧场研究站（Southern Plains Range Research Station, SPR）数据集，包含以克每平方米为单位的垂穗草（Bouteloua curtipendula）生物量测量数据，且数据已按年度尺度进行聚合。
