Most protected areas in the world are affected to some degree by invasive species. The spread of plants and animals across the world has been occurring since humans began travelling across the oceans and the continents bringing with them species they like and unknowingly transporting other species.
Invasive species start as strangers in a strange land but over time come to dominate their new homes. The ocean has played host to some of the most prolific of these infiltrations of our time. So just how are these marine invaders able to adapt and thrive in new neighborhoods? This episode is part of our series Long Story Shorts—fun, quick explainers about all things coastal science!
The Aleipata group of offshore islands have been identified as one of eight Key Biodiversity Areas (KBAs) in Samoa. They are located at the south-eastern end of Upolu Island at 14o3’447.28”S, 171o25’23.84”W (Nu’utele) and 14o4’22.11”S and 171o24’36.17”W (Nu’ulua) offshore. This project updates population estimates and establish baseline data and information on breeding seabirds of the Aleipata offshore islands and investigate the feasibility of future tracking studies of some species.
Islands support unique plants, animals, and human societies found nowhere else on the Earth. Local and global stressors threaten the persistence of island ecosystems, with invasive species being among the most damaging, yet solvable, stressors. While the threat of invasive terrestrial mammals on island flora and fauna is well recognized, recent studies have begun to illustrate their extended and destructive impacts on adjacent marine environments.
A BIORAP is a biological inventory programme undertaken in marine and terrestrial environments, and is designed to rapidly assess the biodiversity of highly diverse areas. Options to manage threats and protect some remaining examples of indigenous biodiversity of national or international significance are recommended to governing communities.The Nauru BIORAP took place in selected terrestrial and marine areas of the Republic of Nauru during 17–27 June, 2013. The key finding of the Nauru BIORAP are presented in this synthesis report.

Pacific Island biodiversity has a notorious record of decline and extinction which continues due to habitat loss and degradation, invasive species, overexploitation, pollution, disease and human-forced climate change. In terrestrial systems, these global and local pressures are more acute because of relatively small land to sea area, high endemism and poor adaptations to resist predation.
Despite islands contributing only 6.7% of land surface area, they harbor ~20% of the Earth’s biodiversity, but unfortunately also ~50% of the threatened species and 75% of the known extinctions since the European expansion around the globe. Due to their geological and geographic history and characteristics, islands act simultaneously as cradles of evolutionary diversity and museums of formerly widespread lineages—elements that permit islands to achieve an outstanding endemicity.
Human pressure mapping is important for understanding humanity’s role in shaping Earth’s patterns and processes. We provide the latest maps of the terrestrial human footprint and provide an assessment of change in human pressure across Earth. Between 2000 and 2013, 1.9 million km2 of land relatively free of human disturbance became highly modified. Our results show that humanity’s footprint is eroding Earth’s last intact ecosystems and that greater efforts are urgently needed to retain them.
The purpose of this Biodiversity Strategy and Action Plan (BSAP) is to Assist the Marshall Islands to Plan for the Conservation of its biodiversity and for in the sustainable use of its biological resources. This is the first time that such a strategy and action plan has been formulated for the country. It provides an opportunity for the government of the Republic of the Marshall Islands to integrate principles of sustainable resource management and biodiversity conservation into the national development planning processes.
