Abstract

The many acres of forest land that are occupied by brush in central Oregon represent a large-scale waste of timber-growing capacity and a major economic loss to the area. Although large brushfields devoid of tree growth present the most spectacular examples of loss, less obvious but equally important brush problems are common in established timber stands. Brush frequently overtops and suppresses young seedlings for long periods of time in small natural forest openings and competes with trees of all sizes for soil moisture.
