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.

Rodent predation on eggs and chicks is one of the main threats to procellariiform species in the Mediterranean, where the black rat (Rattus rattus) and brown rat (R. norvegicus) have been present on many islands for centuries. The yelkouan shearwater (Puffinus yelkouan) is an endemic Mediterranean seabird species classified as vulnerable. Malta holds up to 10% of the global population; the largest colony, Rdum tal-Madonna (RM), protected as a Natura 2000 site, hosts around 500 breeding pairs. This colony has been monitored since its discovery in 1969. A very low reproductive success due to rat predation was noticed in the late 1990s to early 2000s. In 2007 a seasonal rodent control programme was established during the breeding season of yelkouan shearwater to reduce rat predation on eggs and chicks. Rodent control took place between 2007 and 2010 and was reviewed and continued from 2012 to 2017. Breeding success since 2007 has been higher than 80%. In two other colonies with rat presence and where rodent control did not take place, the breeding success in 2016 and 2017 was substantially lower than in the colony with the rodent control programme. The European storm-petrel (Hydrobates pelagicus melitensis) only breeds in rat-free areas like remote sea caves or islets around the Maltese islands. In 2014, the first breeding attempt by European storm-petrel was recorded on the Maltese mainland at RM with a chick fledging successfully for the first time in 2016. The ongoing LIFE Arcipelagu Garnija project is assessing rat predation in all Maltese yelkouan shearwater colonies in order to establish predator control in the most important yelkouan shearwater breeding sites in 2018.
