Inventories

Natural resource inventories are extensive, point-in-time efforts to determine the location or condition of resources.

The primary purpose of these inventories is to assess and document the current condition and knowledge of natural resources in the parks, providing a solid baseline for long-term monitoring and management. Inventories allow comparison of existing conditions to the natural or desired state of parks.

NCRN Inventories

These inventories were intended to fill-in data gaps on species status and abundance for vertebrate and vascular plant species in the parks through targeted field investigations.

Basic Natural Resource Inventories

Twelve basic resource inventories are defined as part of the Natural Resources Inventory and Monitoring Guidelines (NPS-75). They are intended to provide park managers with the minimum information needed to effectively manage the natural resources of their park.

  1. Air Quality - focuses on indicator pollutants regulated under the Clean Air Act, including ozone, particulate matter, visibility, mercury, and acid deposition of nitrogen and sulfur. Air quality data is displayed by park in an NPS Air Quality Conditions & Trends Tool and also in web map in the NPS AirAtlas .
  2. Air Quality Related Values - provides information on the types and amounts of air pollutants that cause harmful changes to resources including: visibility, vegetation, soils, water, fish, and wildlife. Download a 2016 report on Air Quality Related Values for National Capital Region Network Parks here.
  3. Base Cartography - Online access to legacy and current geospatial data sets is provided by the USGS National Map and EarthExplorer, as well as the US Department of Agriculture Geospatial Data Gateway. These federal systems have superseded NPS efforts to acquire and store digital spatial data files.
  4. Climate - provides access to climate data on NPS lands. Access to climate data, especially in light of climate change, is fundamental to our understanding of the status of ecosystems and species and their response to climate variability. Download the full NCRN Weather and Climate Inventory report.
  5. Geologic Resources - provides digital geologic map data, and a park-specific geologic report. This inventory aims to raise awareness of geology and the role it plays in the environment. Full reports, data, and maps can be found at the NPS Geologic Resources Inventory Publications Page.
  6. Natural Resource Bibliography - Natural resource-related information products concerning national parks are managed and cataloged in the IRMA Data Store.
  7. Soils Resources - Includes maps of the locations and extent of soils; data about physical, chemical, and biological properties of those soils; and information about use issues for each kind of soil. Data and reports are here under "Soil Survey Data".
  8. Species Lists - The core of the species lists inventory is NPSpecies, a web-based system that provides a way to build, manage, and share park species information. NPSpecies includes standardized information on species occurrence in parks, including scientific names and their synonyms, common names, abundance, residency, nativeness, and more. Park species lists through NPSpecies are available on the NCRN website.
  9. Vegetation (Map) Inventory - includes classifications, descriptions, and detailed maps of vegetation communities for each park. The NPS Vegetation Inventory Products page provides links to all final products.
  10. Baseline Water Quality - Baseline physical, chemical, and biological water quality data that was collected, documented, and summarized from existing, readily-available, digital water quality data collected in the vicinity of parks. Data is located at the on the NPS Baseline Water Quality Data Inventory & Analysis webpage.
  11. Water Body Location and Classification - A high-resolution (1:24,000, 1:63,360 in Alaska) database for 8-digit hydrologic units/sub-basins containing national park units is available as the National Hydrography Dataset. The Hydrographic and Impairment Statistics database provides water impairment summary statistics of surface hydrography (acres of lakes, miles of streams, etc.) within and adjacent to each national park unit.
