Guam invasive species management plan interim 2017-2019: interim
BRB
Available Online
2017
The 2017-2019 Interim Guam Invasive Species Management Plan (GISMP) expresses the overarching goals and priorities of the Guam Invasive Species Council (GISC or Council). The Guam Invasive Species Act of 2011 (Public Law 31-43) established the Council as Guam’s lead entity in coordinating with local, regional, national, and international jurisdic¬tions in the fight against alien invasive species. Although the GISC is in its infancy stages of organization, it draws from the collective knowledge, past research, and progress of its members in establishing the Council’s goals and priorities. Priorities and goals identified in this plan reflect current and near-term resources, member capabilities, and status of certain invasive species. Recommendations contained in the Regional Biosecurity Plan for Micronesia and Hawaii (RBP), the 2016-2018 National Inva¬sive Species Council’s Management Plan, the Regional Invasive Species Council (RISC), and various stakeholders were considered in the development of this plan. The Council also considered developments under the purview of the Hawaii Invasive Species Council and its 2015-2020 HISC Strategic Plan.

Economic impacts from invasive species, conveyed as expected damages to assets from invasion and expected costs of successful prevention and/or removal, may vary significantly across spatially differentiated landscapes. We develop a spatial-dynamic model for optimal early detection and rapid-response (EDRR) policies, commonly exploited in the management of potential invaders around the world, and apply it to the case of the Brown treesnake in Oahu, Hawaii. EDRR consists of search activities beyond the ports of entry, where search (and potentially removal) efforts are targeted toward areas where credible evidence suggests the presence of an invader. EDRR costs are a spatially dependent variable related to the ease or difficulty of searching an area, while damages are assumed to be a population dependent variable. A myopic strategy in which search only occurs when and where current expected net returns are positive is attractive to managers, and, we find, significantly lowers present value losses (by $270m over 30 years). We find further that in the tradeoff between search costs and damages avoided, early and aggressive measures that search some high priority areas beyond points of entry even when current costs of search exceed current damages can save the island more ($295m over 30 years). Extensive or non-targeted search is not advised however.
