Niue State of Environment Report 2019
SPREP Publications, Environmental Monitoring and Governance, Island and Ocean Ecosystems
Available Online
2020
In terms of both population and land area. Niue is one of the smallest self-governing nations in the world. It is unique by its formation as an uplifted coral atoll.
Federated States of Micronesia (FSM): State of the Environment (SOE) report 2018
SPREP Publications, Environmental Monitoring and Governance
Available Online
2019
The FSM State of Environment report presents concise information on the state of the environment for the Federated States of Micronesia. The report revealed the current state of knowledge about the environment in FSM along the following thematic areas: atmosphere and climate, water, land, marine, biodiversity, built environment, and culture and heritage. The report informed that there are a lot of environmental challenges in the FSM and the report will be used as a vehicle to the national and state governments and how it can improve its decision and policy making mechanisms.

It is widely recognized that trophic interactions structure ecological communities, but their effects are usually only demonstrated on a small scale. As a result, landscape-level documentations of trophic cascades that alter entire communities are scarce. Islands invaded by animals provide natural experiment opportunities both to measure general trophic effects across large spatial scales and to etermine the trophic roles of invasive species within native ecosystems. Studies addressing the trophic interactions of invasive species most often focus on their direct effects. To investigate both the presence of a landscape-level trophic cascade and the direct and indirect effects of an invasive species, we examined the impacts of Norway rats (Rattus norvegicus) introduced to the Aleutian Islands on marine bird densities and marine rocky intertidal community structures through surveys conducted on invaded and rat-free islands throughout the entire 1,900-km archipelago. Densities of birds that forage in the intertidal were higher on islands without rats. Marine intertidal invertebrates were more abundant on islands with rats, whereas fleshy algal cover was reduced. Our results demonstrate that invasive rats directly reduce bird densities through predation and significantly affect invertebrate and marine algal abundance in the rocky intertidal indirectly via a cross-community trophic cascade, unexpectedly changing the intertidal community structure from an algae- to an invertebrate-dominated system.
The Republic of the Marshall Islands: State of the Environment (SOE) Report 2016
Available Online
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.
