The Network ConceptAcross the country, more than 280 parks with significant natural resources have been grouped into 32 "networks." Network boundaries are based on geography and the natural resource characteristics parks have in common.
Parks within each of the networks work together to plan, design, and conduct inventories and long-term monitoring. Today, all I&M networks collect, analyze, and provide park managers with reliable scientific information about key park resources, known as "vital signs."
Information gathered by Inventory & Monitoring networks is shared widely. Network staff produce technical reports, resource briefs, and journal publications, and each network has a website. Use the map below to start exploring our science.
