Westwide Pine Beetle Model

The Westwide Pine Beetle model simulates impacts of mountain beetle (Dendroctonus ponderosae Hokpins), western pine beetle (D. brevicomis Leconte), and Ips species for which western pines are a host.

Model Description

The Westwide Pine Beetle (WWPB) Model (FHTET, in press) simulates the mortality impacts of mountain pine beetle (Dendroctonus ponderosae Hopkins), western pine beetle (Dendroctonus brevicomis LeConte), and Ips spp. on western pine tree species. It is a multi-stand, landscape-scale model that recognizes the conditions and events occurring in all simulated stands. The WWPB Model utilizes the FVS Parallel Processor (Crookston and Stage 1991) to model multiple stands simultaneously throughout simulated time. The model uses a set of stand conditions to determine the relative attractiveness (to beetles) of stands in the landscape, and the susceptibility (to beetle attack) of diameter classes of host species within stands. Beetle mortality is simulated on an annual basis. Custom ArcView® projects have been developed to display results of this model in a map format.

Users invoke the Westwide Pine Beetle extension using the BMPPIN keyword. The keywords of this extension are supported in Suppose. See the Westwide Pine Beetle Model keyword guide for details. This extension is available for some of the western variants of FVS and will be made available others upon request.

The Forest Health Technology Enterprise Team in Fort Collins, Colorado currently supports this extension.
