North Temperate Lakes site, station Oneida County, WI (FIPS 55085), study of number of farms in units of number 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 North Temperate Lakes (NTL)
contains number of farms measurements in number units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（约纳盆地长期生态研究站，美国农业部农业研究服务局约纳实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站，美国农业部林业局卢奎洛实验林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。本项目为大型综合整合研究项目，核心目标为提升长期数据的可获取性与应用水平。目前已有约50个州级与联邦资助的科研站点参与并为EcoTrends项目提供数据支持，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（ARS）、美国农业部林业局、美国能源部、美国地质调查局（USGS）与众多高校资助的站点。EcoTrends项目的数据可通过探索式数据门户（http://www.ecotrends.info）获取。该门户依托交互式网页应用，为用户提供持续的数据整合与数据获取服务。持续的数据整合工作依托LTER溯源感知综合跟踪架构（PASTA），通过手动与自动结合的处理方式完成更新。本数据门户由约纳盆地LTER站与LTER网络办公室联合开发。本次收录的北温带湖泊（NTL）数据集包含以数值单位记录的农场数量测量数据，并已聚合至年度时间尺度。
