Globally, groundwater dependent ecosystems (GDEs) are increasingly vulnerable to groundwater extraction and land use practices. Groundwater supports these ecosystems by providing inflow, which can maintain water levels, water temperature, and chemistry necessary to sustain the biodiversity that they support. Many aquatic systems receive groundwater as a portion of base flow, and in some systems (e.g., springs, seeps, fens) the connection with groundwater is significant and important to the system’s integrity and persistence. Groundwater management decisions for human use may not consider ecological effects of those actions on GDEs, which rely on groundwater to maintain ecological function. This disconnect between...

The GAP National Terrestrial Ecosystems - Ver 3.0 is a 2011 update of the National Gap Analysis Project Land Cover Data - Version 2.2 for the conterminous U.S. The GAP National Terrestrial Ecosystems - Version 3.0 represents a highly thematically detailed land cover map of the U.S. The map legend includes types described by NatureServe's Ecological Systems Classification (Comer et al. 2002) as well as land use classes described in the National Land Cover Dataset 2011 (Homer et al. 2015). These data cover the entire continental U.S. and are a continuous data layer. These raster data have a 30 m x 30 m cell resolution. GAP used the best information available to create the land cover data; however GAP seeks to improve...

This data release is a summarization of the US Geological Survey National Land Cover Database (NLCD) 2001, 2004, 2006, 2008, 2011, 2013, 2016 and 2019 Land Cover datasets and the Landscape Ecology Lab at the University of Massachusetts Designing Sustainable Landscapes (DSL) datasets within the USGS Spatial Hydro-Ecological Decision System (SHEDS) framework. The output is a series of tables consisting of the summarized values of continuous variables and discrete variables, respectively, for each local SHEDS catchment within the SHEDS Hydro-Region 2 for both datasets. An additional output are tables of the continuous and discrete variables individually processed through an upstream accumulation method for each catchment...

Mission Statement: The mission of the cooperative is to facilitate coordinated collection of high quality broad-based soil data to evaluate temporal dynamics, to complement meteorologic, hydrologic and biologic monitoring, and to support decision making and science education. Objectives: Develop and share protocols for field and lab soil sampling and analysis Identify information needs that would benefit policy and management decisions Establish a rigorous multi-scale soils collection program whose continuity is maintained while responding to emerging issues. Synthesize existing soil monitoring data, including a critical review of past research and analysis of time scales of various soil dynamics Compile...
Groundwater influenced ecosystems (GIEs) are increasingly vulnerable due to groundwater extraction, land use practices, and climate change. These ecosystems receive groundwater inflow, which can maintain water levels, water temperature, and chemistry necessary to sustain the biodiversity that they support. Many aquatic systems receive groundwater as a portion of their baseflow or water budget, and in some systems (e.g., springs, seeps, fens) this connection with groundwater is central to the system’s integrity and persistence. Groundwater management decisions for human use often do not consider the ecological effects of those actions on GIEs. This disparity can be attributed, in part, to a lack of information regarding...
