Descriptive nameUSGS Protected Areas Database--Arizona
File namepad_usgs
Spatial domainArizona
AbstractThe USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public open space and voluntarily provided, private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastral Theme (http://www.fgdc.gov/ngda-reports/NGDA_Datasets.html). PAD-US is an ongoing project with several published versions of a spatial database of areas dedicated to the preservation of biological diversity, and other natural, recreational or cultural uses, managed for these purposes through legal or other effective means. The geodatabase maps and describes public open space and other protected areas. Most areas are public lands owned in fee; however, long-term easements, leases, and agreements or administrative designations documented in agency management plans may be included. The PAD-US database strives to be a complete “best available” inventory of protected areas (lands and waters) including data provided by managing agencies and organizations. The dataset is built in collaboration with several partners and data providers (http://gapanalysis.usgs.gov/padus/stewards/).

Arizona Game & Fish Department is the current state steward for the PAD-US coverage in Arizona, and it compiled updates for the most recent version (1.4) in 2013. See more information.
Known errors/qualificationsThe most recent version (1.4) of PAD-US was published by the US Geological Survey's GAP Analysis Program in May 2016. Data come from many contributing organizations and are continuously being updated and improved. Some geometry errors are apparent--potentially due to digitization, mismatched projections, varying levels of precision or non-current data.

Some County-owned preserves are NOT on this layer, and land ownership and GAP status on PAD-US may not conform to the latest available information through Pima County. PAD-US does include a number of the 1997 and 2004 open space bond acquisitions.
