Abstract

Due to the ecological and social importance of large, old (presettlement) trees, it is often desirable to protect them when planning forest treatments, and a diameter cap is one way to try to accomplish this. A diameter cap is a limitation on cutting trees above a certain diameter during treatment implementation. Some environmental and conservation groups have advocated for them and caps have been implemented on a range of projects in the western U.S. Nevertheless, there is little knowledge of the potential effects of a diameter cap on forest resources. The large scale restoration treatments proposed by the Four Forest Restoration Initiative (4FRI) in northern Arizona provide an opportunity to use current stand data (Fig. 1A) and treatment prescriptions targeting desired future conditions (Fig. 1B) to provide insights into the use of diameter caps on a variety of forest resource responses. This fact sheet's purpose is to give an overview of the effects of diameter cap implementation on a variety of forest resources in ponderosa pine (Pinus ponderosa) stands within the Coconino National Forest, Arizona.
