Data Acquisition

The northern region’s forests stretch across a complicated landscape with numerous stressors that impact forest health and ultimately, human health.

Our Research

A strategic-level inventory is conducted to monitor and assess forest character and health for the 20-state northern region, as well as four Plains States.  The inventory is an ongoing annual process that provides updates on conditions each year.  The strategic-level inventory generates the broadest information we have and is integrated into a national system of Forest Inventory and Analysis.  This level of monitoring compliments other station efforts at more tactical levels thus providing a scalable system of monitoring that allows monitoring that ranges from woodlots to eco-regions.

Expected Impact

The result of having up-to-date scalable monitoring of northern forests is the ability to evaluate trends in forest health so that policymakers, forest managers, and others within the environmental community can make informed decisions.
