Intermountain Forest Tree Nutrition Cooperative

The IFTNC is a research cooperative composed of public and private forestry organizations interested in diagnosing forest site nutrient availability by site type to prescribe appropriate treatments to achieve management objectives. The IFTNC has established over 250 long-term study areas in Oregon, Idaho, Washington and Montana, covering forested areas throughout the Intermountain Northwest—from the east side of the Cascades to the west side of the Rocky Mountains.

IFTNC research concentrates on conservation of nutrients through proper harvesting, site preparation, stand establishment and density control, as well as enhancement through fertilization. Evaluation of multi-nutrient availability is key to optimizing vigorous forest growth under the diverse site conditions found in the Intermountain Northwest. The IFTNC administration is located in the College of Natural Resources at the University of Idaho, under the direction of Dr. Mark Coleman. The cooperative is governed by a steering committee composed of one representative from each member organization.
