Natural Resource Monitoring

The Inventory & Monitoring (I & M) program was created to monitor the natural resouces of more than 200 National Parks. Monitoring may be how NETN tracks the health of 13 National Parks in the Northeast, but protocols are how the monitoring is accomplished. Monitoring protocols describe what will be measured where, how, and how often. They are detailed study plans designed to verify that if changes are detected by monitoring, they are actually occurring and not being caused by measurement variability or the use of differing monitoring methods.

Each monitoring protocol includes a narrative providing the rationale for selecting a particular resource for monitoring, a framework for making necessary decisions or revisions relative to that protocol and its development, and standard operating procedures (SOP's) that explain, step-by-step, how each procedure will be accomplished. Some protocols are updated on a yearly basis and some remain unchanged for several years.

Vital Signs

Because most protocols address multiple vital signs, the NETN program is organized around protocols, rather than vital signs. What are "vital signs"? The I & M program defines a vital sign as "a subset of physical, chemical, and biological elements and processes of park ecosystems that are selected to represent the overall health or condition of park resources, known or hypothesized effects of stressors, or elements that have important human values" (https://science.nature.nps.gov/im/monitor/). Many vital signs apply to multiple parks in the network, creating a framework for a standardized, comprehensive monitoring program.

NETN vital signs were selected based on conceptual models and prioritized based on importance, management needs, and feasibility of implementation. These vital signs provide a peer-reviewed, prioritized list of monitoring categories that helps guide NETN's monitoring program. The table below shows NETN monitoring protocols and the parks that employ them.
