The Northeast Temperate Network (NETN) was established by the US National Park Service (NPS) to monitor ecological conditions in 13 parks located in seven northeastern states as well as six additional states through which the Appalachian National Scenic Trail passes. The broad-based, scientifically sound information obtained through long term natural resource monitoring will have multiple applications for management decision-making, research, education, and promoting public understanding of park resources.

Knowing the condition of natural resources in national parks is fundamental to the NPS's ability to manage park resources. Parks are open systems, and the challenge of protecting and managing their natural resources requires a partnership-based ecosystem approach. Natural resource monitoring provides site-specific information needed to understand and identify change in complex, variable, and imperfectly understood natural systems and to determine whether observed changes are within natural levels of variability.
