Science Supporting Parks

The National Park Service cares for our parks and the diverse life they support, so that future generations can enjoy and learn from them just as we do. 

In 32 Inventory and Monitoring networks across the country, we gather, analyze, and communicate information on specific park natural resources—the plants, animals, and ecosystems that can indicate the overall biological health of parks. Inventories help us understand the range of natural resources in and around parks. Monitoring helps us understand how these resources are doing over the long term. 

Good decisions start with good information. The information we collect helps parks make sound, science-based management decisions that help us preserve America's special places.

    Why We Monitor

    The National Park Service Inventory and Monitoring Program conducts long-term ecological monitoring within National Park sites, collaborates with a variety of partners, and provides valuable data to park managers and the public.

Inventories

A set of basic inventories, including vegetation, species, landforms, air, and water, gives us a common starting point for monitoring.

Monitoring

Through careful, consistent long-term monitoring, we can detect if park resources are stable or might be changing.

Monitoring for Climate Change

When coupled with climate trends, long-term monitoring can help park managers make decisions in the context of a changing climate.

How do we know if parks are healthy? We measure their vital signs, of course!
