Protected Areas Database of the United States (PAD-US) 3.0 - World Database on Protected Areas (WDPA) Submission
The United States Geological Survey (USGS) - Science Analytics and Synthesis (SAS) - Gap Analysis Project (GAP) manages the Protected Areas Database of the United States (PAD-US), an Arc10x geodatabase, that includes a full inventory of areas dedicated to the preservation of biological diversity and to other natural, recreation, historic, and cultural uses, managed for these purposes through legal
Ken Pierce's Legacy Field Notebooks and Annotated Aerial Photographs, Geological, and Topographical Maps from Across the Western United States 1963-2021 (ver. 2.0, January 2024)
Ken Pierce was a Research Geologist with the U.S. Geological Survey for over 55 years and authored numerous scientific papers, geologic maps, and field trip guides. This data release contains digital scans of 44 field notebooks authored by Ken Pierce or his collaborators. Information contained in these notebooks provided much of the underpinning of Ken Pierce's research on the glacial and geomorph
United States Register of Introduced and Invasive Species (US-RIIS) (ver. 2.0, November 2022)
Introduced (non-native) species that become established may eventually become invasive, so tracking all introduced species provides a baseline for effective modeling of species trends and interactions, geospatially and temporally.
The United States Register of Introduced and Invasive Species (US-RIIS) (ver. 2.0, November 2022, https://doi.org/10.5066/P9KFFTOD), as of 2022-10-23, is comprised of t
Protected Areas Database of the United States (PAD-US) 3.0 (ver. 2.0, March 2023)
The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme ( https://communities.geoplatform.gov/ngda-cadastre/ ). The PAD-US is an ongoing project with several published versions of a spatial database
Protected Areas Database of the United States (PAD-US) 3.0 Spatial Analysis and Statistics
Spatial analysis and statistical summaries of the Protected Areas Database of the United States (PAD-US) provide land managers and decision makers with a general assessment of management intent for biodiversity protection, natural resource management, and outdoor recreation access across the nation. This data release presents results from statistical summaries of the PAD-US 3.0 protection status (
Burn Severity Portal, a clearing house of fire severity and extent information (ver. 7.0, April 2024)
The various post-fire data products available on the Burn Severity Portal are produced using satellite imagery. The timing of the satellite imagery used, relative to the fire event, typically depends on the vegetation type and structure where the fire occurred. Each mapping program produces a suite of data products based on user intended user needs. For more information about each of the programs,
Grain-size analysis data of sediment samples from the beach and nearshore environments at the Pea Island National Wildlife Refuge DUNEX site, North Carolina in 2021
These data provide grain-size measurements from sediment samples collected as part of the USGS DUring Nearshore Event eXperiment (DUNEX) site on Pea Island National Wildlife Refuge, NC. DUNEX is a multi-agency, academic, and non-governmental organization collaborative community experiment designed to study nearshore coastal processes during storm events. USGS participation in DUNEX will contribute
Anthropogenic Disturbances and Natural Variables in the Conterminous United States Linked to Catchments and Buffers of the National Hydrography Dataset Plus Version 2.1
This USGS data release contains landscape variables representing anthropogenic disturbances to stream habitats and natural variables summarized within local and network stream catchments of the National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1) as well as a 90 meter local and network buffer of stream reaches throughout the conterminous U.S. The source datasets compiled and attributed to
Fluvial Fish Native Distributions for the Conterminous United States using the NHDPlusV2.1 and Boosted Regression Tree (BRT) Models
This USGS data release documents species distribution models for 271 fluvial fish species in their native ranges of the conterminous United States. Source data, supporting code and model results are documented in this data package. Boosted Regression Tree (BRT) models were used to develop presence/absence predictions for each of the National Hydrography Dataset Plus Version 2.1 stream segments w
Coarse Range Maps for Fish Species in the Conterminous United States using HUC8s
This USGS data release documents coarse ranges for 123 fish species in the conterminous United States for level 8 hydrologic units from the Watershed Boundary Dataset (WBD). These range maps were derived by combining known fish occurrence information from four data sources: point occurrences from the Aquatic Gap Analysis Project (AGAP) fish database, point occurrences from the IchthyMaps dataset,
Dam Metrics Representing Stream Fragmentation and Flow Alteration for the Conterminous United States Linked to the NHDPLUSV2.1
This USGS data release includes a comma separated value (CSV) file that contains 19 reach-based dam metrics representing stream fragmentation and flow alteration for nearly 2.3 million stream reaches in the conterminous United States. Dam metrics fall into three main categories: count and density, distance-based, and cumulative reservoir storage (described below). These data were developed using
Presence Absence Database of Fish in the Conterminous United States
This USGS data release documents presence and absences of 271 fish species in the conterminous United States for 35,918 stream reaches of the National Hydrography Dataset Plus Version2.1 (NHDPlusV2.1). Sample dates for this dataset span 1990-2019. Fish samples were aligned to the Integrated Taxonomic Information System (ITIS), where each species record was assigned a Taxonomic Serial Number (TSN).
