This map package contains four resistance surfaces, one which is the same surface at two different resolutions (30m and 90m). The resistance surfaces were used in Linkage Mapper and Omniscape to model naturalness connectivity in Southwest Washington. Naturalness resistance values from all the inputs can be found in the report methodology.We made three different resistance surfaces, using the data inputs, found here, for testing in sensitivity analyses. For the first, we started with a conventional methodology for creating resistance surfaces (Using Gnarly Landscape Utilities), and then combined this result with nuanced layers about road impacts and building density impacts. These nuanced layers have continuous numerical...

The U.S. Geological Survey collected groundwater samples from 71 domestic wells and 4 springs in Nevada, Yuba, Sierra, and Placer Counties, California in 2015-2016. The wells and springs were sampled for the Yuba and Bear Watersheds Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic drinking water supply. The Yuba and Bear Watersheds Shallow Aquifer Study Unit includes portions of the watersheds of the Upper Yuba (hydrologic unit code 18020125) and Upper Bear (hydrologic unit code 18020126) that are within the Sierra Nevada Province....

A geodatabase containing shapefiles representing the geologic units present within the study area, as well as the locations where sampling ocurred, field photography conducted by John Armentrout ocurred, and satellite imagery providing overhead views of key points of John Armentrout's study.

This data set contains features representing potentially restorable wetlands (PRW). Potentially restorable wetlands are defined as those areas that are not currently classified as wetland by the USFWS National Wetland Inventory, and have hydric soil characterisitcs that would support hydrophytic vegetation. Input data for generating this layer includes soils data in SSURGO format, and the current National Wetlands Inventory (NWI) wetlands data. The soils data was used to extract those areas that have a dominant drainage class attribute of poorly or very poorly drained. These soils are considered capable of supporting wetland vegetation. The PRW layer does not include existing wetlands. This data covers the entire...

This map package shows the priority areas agreed upon by the ALI on 2/3/2014 (Map A-11 in the report "Arid Lands Initiative. 2014. Spatial Conservation Priorities in the Columbia Plateau Ecoregion: Methods and data used to identify collaborative conservation priority areas for the Arid Lands Initiative.")

Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are accelerated by climate change.

The East Pisco Basin is one of several forearc basins situated on the coastal plain of Peru between the Andean Cordillera and Peru-Chile Trench. During the Cenozoic, successive marine transgressions across the East Pisco Basin deposited sequences of Paleogene and Neogene age. Biochronologic studies suggest that a hiatus of approximately 12 million years (~32-20 Ma) separates the youngest Paleogene deposits from the oldest Neogene deposits. A newly recognized lower Miocene sequence, provisionally named the Tunga Formation, shortens that hiatus. The following database provides location and description of samples from the East Pisco Basin, checklists of microfossil assemblages, and taxonomic notes for those assemblages.
