Guam invasive species management plan interim 2017-2019: interim

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.
Eradication programmes complicated by long-lived seed banks: lessons learnt from 15 years of miconia control on O'ahu Island, Hawai'i
Island and Ocean Ecosystems, BRB

2019
The invasive tree Miconia calvescens (Melastomataceae) is a priority for control on the Hawaiian Island of O?ahu due to its potential to replace native ??hi?a (Metrosideros polymorpha, Myrtaceae) forests and degrade watershed function if allowed to establish. The O?ahu Invasive Species Committee (OISC) is attempting to eradicate this species from the island of O?ahu. OISC uses a bu?er strategy based on estimated seed dispersal distance to determine the area under surveillance. This strategy has worked well enough to suppress the number of trees reaching reproductive age. The number of mature trees removed annually is now less than the number initially removed when the programme started in 2001. In 2016, just 12 mature trees were removed from 54.71 km2 surveyed compared to 2002, when 40 mature trees were removed from 8.26 km2 surveyed, a 96% drop in mature trees per square kilometre surveyed. However, miconia has a long-lived seed bank and can germinate after 20 years of dormancy in the soil. Funding shortages and gaps in surveys due to refusal of private property owners to allow access have resulted in some long-range extensions. OISC’s results suggest that seed bank longevity is an important factor when prioritising invasive species risk and that allocating more resources at the beginning of a programme to eradicate a species with long-lived seed banks may be a better strategy than starting small and expanding.
Be On the LookOut (BOLO): Coconut Rhinoceros Beetle Oryctes rhinoceros (Linneaus, 1758) Coleoptera: Scarabaeidae

2014
Recent PPQ survey interceptions of the Coconut Rhinoceros Beetle (Oryctes rhinoceros) confirms that this serious pest of coconut palms is established in the Hickam AFB area. A joint PPQ– HDOA effort has recently discovered a large compost heap at Mamala Bay golf course containing all stages of development. Native to southern Asia, this scarab has caused extensive damage to coconut palms on Guam since their discovery in 2009.
