Description: Fee and conservation easement held land
he California Protected Areas Database (CPAD) contains data on lands owned in fee by governments, non-profits and some private entities that are protected for open space purposes. Data includes all such areas in California, from small urban parks to large national parks and forests, mostly aligned to assessor
Description: Critical habitats are areas considered essential for the conservation of a listed species. Federal agencies are required to consult with the U.S. Fish and Wildlife Service on actions they carry out, fund, or authorize to ensure that their actions will not destroy or adversely modify critical habitat. These areas provide notice to the public and land managers of the importance of these areas to the conservation of a listed species. Special protections and/or restrictions are possible in areas where Federal funding, permits, licenses, authorizations, or actions occur or are required.
When a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An area is designated as “critical habitat” after the Service publishes a proposed Federal regulation in the Federal Register and receives and considers public comments on the proposal. The final boundaries of the critical habitat are also published in the Federal Register.

These data identify, in general, the areas of Final critical habitat for Holocarpha macradenia (Santa Cruz tarplant), Euphydryas editha bayensis (Bay checkerspot bufferfly), Rana draytonii (California red-legged frog), Ambystoma californiense (California tiger salamander), Chorizanthe pungens var. pungens (Monterey spineflower) and Chorizanthe robusta var. robusta (Robust spineflower). Data clipped to the Pajaro River watershed.

Description: The Office of Environmental Health Hazard Assessment (OEHHA), on behalf of the California Environmental Protection Agency (CalEPA), announces the availability of the Communities Environmental Health Screening Tool: CalEnviroScreen Version 2.0 (CalEnviroScreen 2.0). CalEnviroScreen is a screening methodology that can be used to help identify California communities that are disproportionately burdened by multiple sources of pollution. The 2.0 report and supporting documents are available at: http://oehha.ca.gov/ej/ces2.html
Description: By census place, tract, and block group where the annual median household income (MHI) that is less than 80 percent of the Statewide annual MHI
Additionally, this map shows the disadvantaged communities for the purpose of SB 535. These areas represent the 25% highest scoring census tracts in CalEnviroScreen 2.0. Additional information on SB 535 is available at www.oehha.ca.gov/ej/sb535.html CalEnviroScreen 2.0 information on indicators and methodology is described in detail at http://www.oehha.ca.gov/ej/ces2.html
Disadvantaged communities in California are specifically targeted for investment of proceeds from the State’s cap-and-trade program. These investments are aimed at improving public health, quality of life and economic opportunity in California’s most burdened communities at the same time they’re reducing pollution that causes climate change. Authorized by the California Global Warming Solutions Act of 2006 (AB 32), the cap-and-trade program is one of several strategies that California uses to reduce greenhouse gas emissions that cause climate change. Funds received from the program are deposited into the Greenhouse Gas Reduction Fund and appropriated by the Legislature. They must be used for programs that further reduce emissions of greenhouse gases. In 2012, the Legislature passed Senate Bill 535 (De León) directing that, in addition to reducing greenhouse gas emissions, a quarter of the proceeds from the Greenhouse Gas Reduction Fund must also go to projects that provide a benefit to disadvantaged communities. A minimum of 10 percent of the funds must be projects located within those communities. The legislation gives the California Environmental Protection Agency responsibility for identifying those communities. In October 2014, following a series of public workshops to gather public input, CalEPA released its list of disadvantaged communities for the purpose of SB 535. To inform its decision, CalEPA relied on the California Communities Environmental Health Screening Tool (CalEnviroScreen), a tool that assesses all census tracts in California to identify the areas disproportionately burdened by and vulnerable to multiple sources of pollution. Greenhouse Gas Reduction Funds are administered by state and local agencies for a variety of greenhouse-gas cutting programs, including energy efficiency, public transit, low-carbon transportation and affordable housing. Guidelines written by the Air Resources Board help these agencies develop programs that meet statutory requirements for reducing emissions while maximizing the benefits to disadvantaged communities.

Housing growth in and near United States’ protected areas limits their conservation value. Proceedings of the National Academy of Sciences, 107(2): 940-945. Using geographic information systems (GIS), we mapped housing and population counts from the decennial U.S. Census Data at block group level geography to produce a spatially explicit dataset for the coterminous U.S. We also overlaid the raw housing data with the Protected Areas Dataset (PAD version 1.1) to split census block groups into privately and publicly owned sub-blocks, thereby creating a map that more accurately locates where people and houses exist in space. This data is useful within a GIS for mapping and analysis at national, state, and local levels. Purpose: To provide a spatially detailed national assessment of housing density across the coterminous U.S. to support research, policy and management, and inquiries into the effects of housing growth on the environment.
