Lesser Sandhill Crane Range - CWHR B150b [ds3227]

CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found. This data is available for download from the CDFW website: [https://www.wildlife.ca.gov/Data/CWHR]. The following data sources were collated for the purposes of range mapping and species habitat modeling by RADMAP.

California US Congressional Districts Map 2020

Final approved map by the 2020 California Citizens Redistricting Commission for California's United States Congressional Districts; the authoritative and official delineations of California's United States Congressional Districts drawn during the 2020 redistricting cycle. The Citizens Redistricting Commission for the State of California has created statewide district maps for the State Assembly, State Senate, State Board of Equalization, and United States Congress in accordance, with the provisions of Article XXI of the California Constitution. The Commission has approved the final maps and certified them to the Secretary of State. Line drawing criteria included population equality as required by the U.S. Constitution, the Federal Voting Rights Act, geographic contiguity, geographic integrity, geographic compactness, and nesting. Geography was defined by U.S. Census Block geometry. Each of the 52 Congressional districts apportioned to California have an ideal population of 760,066, and the Commission adhered to federal constitutional mandates by requiring a district population deviation of no more than +/- one person. These districts also posed some of the Commission’s biggest challenges, and, because of strict population equality requirements, resulted in many more splits of counties, cities, neighborhoods, and communities of interest compared to State Assembly or Senate plans. This layer was not published by the Assembly or Senate Demographics. 1. [Congressional District Boundaries] from Assembly Bill 604 and certified by the California voters under Proposition 50. These districts will take effect in January 2027 and will remain effect for sitting Congressmembers through 2032. 2. Current [district boundaries] and membership, maintained by USDOT.
CA State Senate Districts and Membership 2025-2030

This is the last boundary change until the next redistricting following the 2030 Census. All of the districts now reflect the 2021 Citizens Redistricting Commission(CRC) plan. The only thing that will change is the members' names and parties as elections are held, appointments are made, or party affiliations change. Senate Districts feature layer is updated as-needed and we expect to update it more regularly in the future. Schema: F2020_POP: The 2020 population of the district as reported by the census. F2020_HU: Number of housing units in the district in 2020 as reported by the census. CRC_POP: Citizen's Redistricting Commission population. District: The District is the district number. Party: The Party is the party represented. last_name: The last name is the last name of the representative. first_name: The first name is the first name of the representative. district_website: The district website is the link to the district website.

California State Senate District Active, Deferred and Accelerated Boundaries 2023-2024

Senate Districts in California with boundaries showing active, deferred, and accelerated district boundaries until the 2024 Election. This data is available at a public level for everyone to use. The active districts are comprised of even district numbers with Senators elected in 2022. These even districts use the boundaries edited in the 2020 Census. They were finalized in 2021 so that is why the districts are referenced with that date. The first election they were ready to be used in was the 2022 Election, but not the 2020 election. The 2020 Election used the boundaries of the districts created in the 2010 Census (finalized in 2011). The odd numbered senate districts used the 2011 boundaries in the 2020 election. These odd senate districts will change to the 2021 Certified districts with the 2024 election cycle. Until then the odd numbered 2011 Certified Senate districts are still active. These even and odd districts are labelled as Active Districts in the layer. Since some of these boundaries were changed, there is overlap of some of the odd and even districts. They are referred to as Accelerated Districts and they occur where an existing odd-district is overlain by a new even-district. The constituents in the accelerated areas will have two Senators who may represent them. Some of the district boundaries were changed so that there are gaps with no district coverage at all. If there is a gap in coverage, the area is referred to as a Deferred District. They occur when an area that was an even-numbered district in the 2011 redistricting plan becomes an odd-numbered district in the 2021 redistricting plan. The area does not have a Senator until the conclusion of the 2024 election when the new odd-numbered district becomes active. During the 2023-2024 session the Senate Rules Committee assigns Senators to provide constituent services in deferred areas.
CA Zip Code Boundaries

This feature service is derived from the Esri "United States Zip Code Boundaries" layer, queried to only CA data. For the original data see: [https://esri.maps.arcgis.com/home/item.html?id=5f31109b46d541da86119bd4cf213848] Published by the California Department of Technology Geographic Information Services Team. The GIS Team can be reached at ODSdataservices@state.ca.gov. U.S. ZIP Code Boundaries represents five-digit ZIP Code areas used by the U.S. Postal Service to deliver mail more effectively. The first digit of a five-digit ZIP Code divides the United States into 10 large groups of states (or equivalent areas) numbered from 0 in the Northeast to 9 in the far West. Within these areas, each state is divided into an average of 10 smaller geographical areas, identified by the second and third digits. These digits, in conjunction with the first digit, represent a Sectional Center Facility (SCF) or a mail processing facility area. The fourth and fifth digits identify a post office, station, branch or local delivery area. As of the time this layer was published, in January 2025, Esri's boundaries are sourced from [TomTom] (June 2024) and the 2023 population estimates are from [Esri] Demographics. Esri updates its layer annually and those changes will immediately be reflected in this layer. Note that, because this layer passes through Esri's data, if you want to know the true date of the underlying data, click through to [Esri's original source data] and look at their metadata for more information on updates. Cautions about using Zip Code boundary data Zip code boundaries have three characteristics you should be aware of before using them: 1. Zip code boundaries change, in ways small and large - these are not a stable analysis unit. Data you received keyed to zip codes may have used an earlier and very different boundary for your zip codes of interest. 2. Historically, the United States Postal Service has not published zip code boundaries, and instead, boundary datasets are compiled by third party vendors from address data. That means that the boundary data are not authoritative, and any data you have keyed to zip codes may use a different, vendor-specific method for generating boundaries from the data here. 3. Zip codes are designed to optimize mail delivery, not social, environmental, or demographic characteristics. Analysis using zip codes is subject to create issues with the [Modifiable Areal Unit Problem] that will bias any results because your units of analysis aren't designed for the data being studied. As of early 2025, USPS appears to be in the process of releasing boundaries, which will at least provide an authoritative source, but because of the other factors above, we do not recommend these boundaries for many use cases. If you are using these for anything other than mailing purposes, we recommend reconsideration. We provide the boundaries as a convenience, knowing people are looking for them, in order to ensure that up-to-date boundaries are available.

Santa Catalina Island Fox Range - CWHR M150a [ds3288]

CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found. This data is available for download from the CDFW website: [https://www.wildlife.ca.gov/Data/CWHR].
