In the following sections, ways are detailed that data representing human-mediated pathways of forest pest spread have been or may be used for analytical purposes. All of these examples describe ongoing projects, and it is pointed out that validation or other assessment procedures have not been completed. Although that is an ultimate goal, for now some of the capabilities of the described data sets are illustrated and, thus, users are encouraged to integrate them in additional forest pest risk mapping efforts.
Subsections found in Application Examples
- Sirex Woodwasp and Foreign Marine Cargo Statistics : The sirex woodwasp (Sirex noctilio) primarily attacks Pinus species but, occasionally, will attack other conifers in the Pinaceae family.
- Wood Product Flows from Canada and Mexico into the United States : Cargo statistics data can also be used to explore risks associated with general pathways rather than specific pests.
- Truck Traffic Data and Risk of Sirex noctilio Spread Beyond Points of Entry : This example builds on the previous example by using spatially explicit transportation network data to predict likely locations of Sirex noctilio spread beyond those initial ports of entry.
- Network Model of Nursery Stock Flows : First recognized in the mid-1990s, the sudden oak death pathogen Phytophthora ramorum has infected live and red oaks in coastal forests in California and Oregon, with mortality rates of approxomately 40 percent.
- Phytophthora ramorum and Production Nurseries : Production nurseries present a higher risk of infecting nearby forests than retail nursery outlets due to several factors: large quantities of stock grown on-site; artificially high moisture levels conducive to the pathogen; and disproportionately large amounts of interface with natural forests.
- Wildland-Urban Interface Data and Areas at Risk for Phytophthera ramorum Introduction : WUI coverages developed by the SILVIS Lab were used to examine spatial patterns of potential residential-to-forest landscape spread risk for P. ramorum.
- Road Density Change and Increased Phytophthera ramorum Risk : A major concern for the refined P. ramorum risk map is identification of areas that may receive large quantities of nursery plant stock that are potentially infected by the pathogen.
