Mohave Desert Tortoise Range - CWHR R005 [ds905]

<div style='text-align:Left;'><div><div><p style='margin:0 0 14 0;'><span><span>Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for California's wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000.

Home Health Agencies & Hospice Annual Utilization Report - Complete Data Set

Home Health Agencies (HHA) provide at home skilled nursing, personal care and therapeutic services. Hospices provide palliative care and alleviate the physical, emotional, social and spiritual discomforts of an individual who is experiencing the last phases of life due to the existence of a terminal disease. In addition, hospices provide supportive care for the primary care giver and the family of the hospice patient. Home health agencies and hospices submit an annual utilization report to the Office at the end of each calendar year.  The report includes information on services capacity, visits, utilization, patient characteristics, and capital/equipment expenditures, and gross revenues. The documentation, including report forms, is available for each reporting year.
Independent Medical Review (IMR) Determinations, Trend

This data is from the California Department of Managed Health Care (DMHC). It contains all decisions from Independent Medical Reviews (IMR) administered by the DMHC since January 1, 2001. An IMR is an independent review of a denied, delayed, or modified health care service that the health plan has determined to be not medically necessary, experimental/investigational or non-emergent/urgent. If the IMR is decided in an enrollees favor, the health plan must authorize the service or treatment requested.
Enforcement Actions, Trend

This data is from the Office of Enforcement in the California Department of Managed Health Care (DMHC). It contains enforcement actions with the information of the organization type, organization name, action date, penalty amount, related party, and violation section (California Health and Safety Code and the California Code of Regulations, title 28) since July 1, 2000. The DMHC Office of Enforcement investigates alleged violations of the Knox-Keene Health Care Service Plan Act of 1975 (the Knox-Keene Act) under the DMHC's administrative powers as a California state licensing agency. The DMHC Office of Enforcement exercises its jurisdiction to prosecute violators in an administrative action before the Director of the DMHC, the Office of Administrative Hearings, or in the California Superior Courts. When the DMHC finds the Knox-Keene Act is violated, the Director is authorized to take a variety of actions, including, assessing administrative penalties and issuing a cease and desist order requiring the subject of the order to stop the offending action. All subjects are afforded appropriate Due Process protections. For additional information, please visit http://www.dmhc.ca.gov/LawsRegulations/EnforcementActions.aspx.
Rate Review Detail, Trend

This data is from the California Department of Managed Health Care (DMHC). It contains all information on health plan proposed premium rates filed with the DMHC since January 1, 2011. The DMHC is committed to providing the public with information in order to expand consumer understanding about premium rate increases. The DMHC does not have the authority to approve or deny rate increases; however, the DMHC's review of proposed premium rates improves accountability in health plan rate setting and often results in a reduction in the proposed rate.
Southern Sea Otter Stranding Database

This dataset is a record of all verified stranded (live sick/injured, dead beached/floating) southern sea otters (Enhydra lutris nereis) in California. The data collected include the date and location of stranding, condition, age class and sex of the animal, morphometrics, and very general external and internal necropsy findings. These data have been collected continually since 1968 and are used to identify unusual mortality events, track causes of anthropogenic mortality for mitigation, and inform resource managers about the extent and causes of mortality affecting the southern sea otter population. These data may also be used during or after an oil spill for Natural Resource Damage Assessment purposes, or to inform best achievable recovery and care of live animals. Prior to 2019, the data were managed by the U.S. Geological Survey (USGS) and data from 1985 to 2018 are available on the USGS website. Data from the earliest years are not yet available in a standardized electronic format, but a subset of the database from 2019 onward is available through this portal. A stranding summary report is also provided for each year starting in 2019.

This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000394. For more information, please visit https://wildlife.ca.gov/Data/Sci-Data.

Fisheries Restoration Grant Program (FRGP) Projects [ds168]

<div style='text-align:Left;'><div><div><p><span>The Fisheries Restoration Grant Program (FRGP) was established in 1981 in response to rapidly declining populations of wild salmon and steelhead trout and deteriorating fish habitat in California. This competitive grant program has invested millions of dollars to support projects from sediment reduction to watershed education throughout coastal California. Contributing partners include federal and local governments, tribes, water districts, fisheries organizations, watershed restoration groups, the California Conservation Corps, AmeriCorps, and private landowners. The FRGP Database began in 1999 to capture and maintain data about habitat restoration projects in California benefiting anadromous fish. The database is managed California Department of Fish and Wildlife (CDFW) and funded by NOAA Fisheries and CDFW. Project locations are based on the grantees maps.

This dataset is a digitized geographical inventory of selected lands owned and/or administered by the California Department of Fish and Wildlife (CDFW). Physical boundaries of individual parcels are determined by the descriptions contained in legal documents and assessor parcel maps relating to that parcel. The approximate parcel boundaries are drawn onto U.S. Geological Survey 7.5'-series topographic maps, then digitized and attributed before being added to the dataset. In some cases, assessor parcel or best available datasets are used to digitize the boundary. Using parcel data to adjust the boundaries is a work in progress and will be incorporated in the future. Township, range, and section lines were based on the U.S. Geological Survey 7.5' series topographic maps (1:24,000 - scale). In some areas, the boundaries will not align with the Bureau of Land Management's Public Lands Survey System (PLSS).</span></p></div></div></div>
