Invasive species pose a significant threat to a primary objective of marine conservation, protecting native biodiversity. To-date, research quantifying invasion risk to marine protected areas (MPAs) is limited despite potential negative consequences. As a first step towards identifying invasion risk to MPAs via vessel ballast or biofouling, we evaluated vessel traffic patterns by applying graph-theoretic concepts for 1346 vessels that connected invaded areas (‘invasion nodes’) along the Northeast Pacific coast to MPAs within Canadian waters in 2016.

One of the aims of the United Nations (UN) negotiations on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction (ABNJ) is to develop a legal process for the establishment of area-based management tools, including marine protected areas, in ABNJ. Here we use a conservation planning algorithm to integrate 55 global data layers on ABNJ species diversity, habitat heterogeneity, benthic features, productivity, and fishing as a means for highlighting priority regions in ABNJ to be considered for spatial protection.

Sustainable Development Goal 14 of the United Nations aims to “conserve and sustainably use the oceans, seas and marine resources for sustainable development”. Achieving this goal will require rebuilding the marine life-support systems that deliver the many benefits that society receives from a healthy ocean. Here we document the recovery of marine populations, habitats and ecosystems following past conservation interventions.

Local communities’ support for resource conservation projects are essential for their success. Nevertheless, in the Pacific Island countries, many community-based conservation (CBC) projects remain ineffective due to the lack of community members’ engagement. To better understand the motivations of local community members to support resource conservation projects; this research looks at the four community-based conservation sites in North Tarawa, Kiribati.
