Invasive alien species (IASs) on islands have broad impacts across biodiversity, agriculture, economy, health and culture, which tend to be stronger than on continents. Across small-island developing states (SIDSs), although only a small number of IASs are widely distributed, many more, including those with greatest impact, are found on only a small number of islands. Patterns of island invasion are not consistent across SIDS geographic regions, with differences attributable to correlated patterns in island biogeography and human development. We identify 15 of the most globally prevalent IASs on islands. IAS impacts on islands are exacerbated through interactions with a number of other global change threats, including over-exploitation, agricultural intensification, urban development and climate change. Biosecurity is critical in preventing IAS invasion of islands. Eradication of IASs on islands is possible at early stages of invasion, but otherwise is largely restricted to invasive mammals, or otherwise control is the only option. Future directions in IAS management and research on islands must consider IASs within a broader portfolio of threats to species, ecosystems and people’s livelihoods on islands. We advocate for stronger collaborations among island countries and territories faced with the same IASs in similar socio-ecological environments.
The Republic of the Marshall Islands: State of the Environment (SOE) Report 2016

2016
The 2016 State of Environment (SOE) Report for the Republic of Marshall Islands (RMI) updates the 1992 SOE report. It uses the DPSIR model (Drivers, Pressures, State, Impact and Response) and aims to:| Document the key drivers and pressures behind the changing environment.| Assess the RMI environment since 1992, using the best available information on the state of RMI’s environment in seven key themes: Atmosphere and Climate, Land, Marine, Biodiversity, Culture and Heritage, Built Environment and Nuclear Legacy.| Document the impacts of environmental changes on the society, economy and environment from changes in the state of the environment.| Document current responses to protect and better manage RMI’s natural resources.| Provide recommendations for RMI to address key challenges and link them to actions in the National Environmental Management Strategy (NEMS) and other key policy documents. This report is comprised of three discussions: 1. Drivers and Pressures in Marshall Islands: A summary of the main points discussed in the Pressures and Drivers section of the report. 2.The State of RMI’s Environment and Impacts on the Society, Economy and Environment: Key findings for each of the seven themes. 3. Responses and Recommendations – Challenges in Moving from Policy to Action: This presents key responses, opportunities, challenges and recommendations.
