This map service is an information surface representing the maximum class within the soil map unit polygon for flooding frequency probability. Each component (and therefore soil map unit polygon) falls into one of the following classes according to NRCS: None, Very rare, Rare, Occasional, Frequent, and Very frequent. This service reports the significant component (making up at least 15% of the map unit) with the maximum flooding frequency probability class. Another service exists for flooding frequency class which reports the dominant class in the soil map unit. The concept is similar but for some cases knowing the dominant flooding frequency component may be a more useful information surface. Esri is providing...
The USGS GAP Analysis Program has developed range maps and distribution models for 1401 species, 604 of which are found within the SRLCC. This record's parent folder contains several examples of GAP species web services. The GAP website has a complete list of available web services for species as well as a map viewer for species data. Species: Bighorn Sheep ( Ovis canadensis) There are two web services for this species: the range map, showing the geographic limits within which the species can be found, and a distribution model, which predicts the environment within the range that is suitable for occupation by the species. Link to metadata for GAP range maps and distribution models. To access services, select...

GAP distribution models represent the areas where species are predicted to occur based on habitat associations. GAP distribution models are the spatial arrangement of environments suitable for occupation by a species. In other words, a species distribution is created using a deductive model to predict areas suitable for occupation within a species range. To represent these suitable environments, GAP compiled existing GAP data, where available, and compiled additional data where needed. Existing data sources were the Southwest Regional Gap Analysis Project (SWReGAP) and the Southeast Gap Analysis Project (SEGAP) as well as a data compiled by Sanborn Solutions and Mason, Bruce and Girard. Habitat associations were...

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of California. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of California. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of conditions...

This map service contains summaries of habitat condition indices (HCI scores) from the National Fish Habitat Action Plan (NFHAP) 2010 assessment for Ecological Drainage Units (EDUs) in the Conterminous United States. Initial HCI scores were developed using landscape factors representing human disturbances summarized to local and network catchments of river reaches throughout the Conterminous United States. Habitat condition scores were based on responsiveness of biological metrics to anthropogenic landscape disturbances throughout ecoregions. Separate scores were created by considering disturbances within local catchments, network catchments, and a cumulative score that accounted for the most limiting disturbance...

This spatial data layer provides an indirect estimate of emergent, scrub-shrub and forested tidal wetland losses for 55 non-lagoonal estuaries spanning the contiguous United States West Coast. Losses are defined as those areas that were tidal wetlands prior to European settlement, but are no longer tidal wetlands today. Losses were estimated by comparing the National Wetland Inventory‘s mapping of current tidal wetlands to the Pacific Marine and Estuarine Fish Habitat Partnership (PMEP)’s West Coast Estuary Extent mapping. The estuary extent layer represents the likely historical extent of tidal wetlands, so areas not identified as current tidal wetlands in the National Wetlands Inventory (NWI) are considered...

The Passage Assessment Database (PAD) geospatial file contains locations of known and potential barriers to salmonid migration in California streams with additional information about each record. The PAD is an ongoing map-based inventory of known and potential barriers to anadromous fish in California, compiled and maintained through a cooperative interagency agreement. The PAD compiles currently available fish passage information from many different sources, allows past and future barrier assessments to be standardized and stored in one place, and enables the analysis of cumulative effects of passage barriers in the context of overall watershed health. The database is set up to capture basic information about each...

The USGS Governmental Unit Boundaries service from The National Map (TNM) represents major civil areas for the Nation, including States or Territories, counties (or equivalents), Federal and Native American areas, congressional districts, minor civil divisions, incorporated places (such as cities and towns), and unincorporated places. Boundaries data are useful for understanding the extent of jurisdictional or administrative areas for a wide range of applications, including mapping or managing resources, and responding to natural disasters. Boundaries data also include extents of forest, grassland, park, wilderness, wildlife, and other reserve areas useful for recreational activities, such as hiking and backpacking....
The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition. NAIP is administered by the USDA's Farm Service Agency (FSA) through the Aerial Photography Field Office in Salt Lake City. This "leaf-on" imagery is used as a base layer for GIS programs in FSA's County Service Centers, and is used to maintain the Common Land Unit (CLU) boundaries. NAIP projects are contracted each year based upon available funding and the FSA imagery acquisition cycle. Beginning in 2003, NAIP was acquired...
