Integrating regeneration, genetic resistance, and timing of intervention for the long-term sustainability of ecosystems challenged by non-native pests - a novel proactive approach


Schoettle, A. W,; Klutsch, J. G.; Sniezko, R. A. 2012. Integrating regeneration, genetic resistance, and timing of intervention for the long-term sustainability of ecosystems challenged by non-native pests - a novel proactive approach. In: Sniezko, R. A.; Yanchuk, A. D.; Kliejunas, J. T.; Palmieri, K. M,; Alexander, J. M.; Frankel, S. J., tech. coords. Proceedings of the Fourth International Workshop on the Genetics of Host-Parasite Interactions in Forestry: Disease and Insect Resistance in Forest Trees. Gen. Tech. Rep. PSW-GTR-240. Albany, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Research Station. p. 112-123.

Global trade increases the likelihood of introduction of non-native, invasive species which can threaten native species and their associated ecosystems. This has led to significant impacts to forested landscapes, including extensive tree mortality, shifts in ecosystem composition, and vulnerabilities to other stresses. With the increased appreciation of the importance of healthy ecosystems for watershed protection, wildlife habitat, and aesthetics, we present a new management approach specifically designed for the long-term sustainability of ecosystems challenged by non-native pests for continued non-timber ecosystem services. Sustaining host population resilience in the presence of a non-native pest requires maintenance of the population's recovery capacity after disturbance, adaptive capacity over time, and multi-generational persistence. Therefore, the management approach must incorporate a long-term and evolutionary perspective which also incorporates continued adaptation to climate change.
