How We Work

What does our inventory and monitoring work entail? What tools and techniques do we use? Some of the answers might surprise you!

National Park managers across the country need a broad-based understanding about the status and trends of park natural resources. The Inventory & Monitoring Division systematically gathers and analyzes information on the plants, animals, and ecosystems that are within parks.

Parks use this information for planning, research, education, and to help guide decisions related to park management. Results are also shared widely with other agencies, researchers, and scientists.

I&M Central Office

Staff at the Inventory and Monitoring Central Office, based in Fort Collins, Colorado, work with all 32 I&M networks to establish priorities, develop standards, and set the overall direction of the division.

I&M is under the National Park Service's Natural Resource Stewardship and Science Directorate (NRSS). The directorate provides scientific, technical, and administrative support to national parks for the management of natural resources

Here's how to contact us.

Primary Goals

Inventory & Monitoring staff and networks share a set of common goals, established when the division was first launched.

  • Inventory the natural resources under National Park Service stewardship to determine their nature and status.
  • Monitor park ecosystems to better understand their dynamic nature and condition and to provide reference points for comparisons with other, altered environments.
  • Establish natural resource inventory and monitoring as a standard practice throughout the National Park system that transcends traditional program, activity, and funding boundaries.
  • Integrate natural resource inventory and monitoring information into National Park Service planning, management, and decision making.
  • Share National Park Service accomplishments and information with other natural resource organizations and form partnerships for attaining common goals and objectives.

To accomplish these goals, more than 280 parks with significant natural resources were grouped into the 32 I&M networks, which were determined based on geography and shared natural resource characteristics. The network organization increases collaboration among parks, information sharing, and economies of scale in natural resource inventory and monitoring.

The 2040 Conservation Initiative

The creation of 32 networks embodied a bold vision in which any National Park Service unit—regardless of size, location, or budget—would have the strong science it needed to support good decisionmaking. Today, more than 270 parks have basic natural-resource inventories. In those parks, ecologists follow strict protocols to track the condition of park “vital signs”—key resources that indicate ecosystem health and provide early warning of problems. And parks have access to a servicewide, user-friendly database of natural-resource information.

Now, we set our sights on 2040. How can we leverage the foundation we’ve built to ensure parks are prepared to meet the challenges ahead? What is the next bold vision that will allow us to capitalize on our progress and propel us through the next two decades?

I&M Conservation Initiative Goal: 2,040 for 2040

By 2040, I&M, together with its partners and parks, will generate 2,040 science-based solutions to promote resilient ecosystems. Learn more about this initiative!
