Santa Barbara Coastal site, station Isla Vista, Santa Barbara Channel, study of animal cover of Phyllactis in units of percent 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 Santa Barbara Coastal (SBC) contains animal cover of Phyllactis measurements in percent units and were aggregated to a yearly timescale.

生态趋势项目（EcoTrends）由黛布拉·彼得斯博士（约尔纳达盆地长期生态研究站，美国农业部农业研究局约尔纳达实验牧场）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收集与分析工作。该项目为一项大型综合研究工程，核心目标是提升长期生态数据的可获取性与应用效能。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并贡献数据至生态趋势项目，其中包含全部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）及众多高校资助的研究站点。生态趋势项目的数据集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汇编并获取相关数据。作为长期生态研究溯源感知综合跟踪架构（PASTA）的组成部分，正在推进的数据汇编工作通过人工与自动处理相结合的方式完成更新。本网络门户由约尔纳达LTER站与LTER网络办公室联合开发。以下来自圣巴巴拉海岸（Santa Barbara Coastal, SBC）的数据集，包含以百分比为单位的叶海葵属（Phyllactis）动物覆盖度测量数据，且已按年际尺度进行聚合。
