An evaluation of tree marking methods for implementing spatially heterogeneous restoration
School of Forest Resources and Environmental Science
Silviculturists are increasingly focused on the development of structurally complex forests through spatially heterogeneous treatments; however, the implementation of these treatments is challenging. We investigated the effectiveness of three tree marking methods used to implement spatially heterogeneous restoration treatments on Colorado’s Front Range: Individual Tree Marking (ITM) physically marks all trees that are either to be cut or left; Designation by Description (DxD) provides a description of the trees that are to be removed based on specific tree characteristics; and Designation by Prescription (DxP) provides the operator with a description of the desired outcomes of the treatment. We employed a mixed methods approach by (a) quantitatively comparing the heterogeneity of stands that have been treated; and (b) interviewing personnel involved in the implementation of these treatments to qualitatively evaluate their efficiency and effectiveness. Neither the quantitative nor the qualitative study methods found a single marking method that was superior to the others in all respects. However, several factors should be considered when selecting a tree marking method, including: the need to set clearly defined silvicultural objectives; personnel experience; trade-offs among personnel; the use of hybrid marking methods; and the range of acceptable outcomes.
