A natural resource inventory is a comprehensive, point-in-time gathering of information. It can assess either the location or condition of a specific resource, or both. It provides baseline information essential to effectively managing park resources over the long term. During its startup in the early 2000s, the NPS Inventory and Monitoring Division identified and helped complete 12 “basic” inventories. These were foundational elements common to all parks with significant natural resources. Some of the more complex inventories are still in progress.

  • Air Quality Data

  • Air Quality Related Values

  • Base Cartography Data

  • Baseline Water Quality Data

  • Climate Inventory

  • Geologic Resources Inventory

  • Natural Resource Bibliography

  • Soil Resources Inventory

  • Species Lists

  • Species Status and Abundance

  • Vegetation Inventory

  • Water Body Location and Classification
