There is a growing recognition that conservation strategies should be designed accounting for cross-realm connections, such as freshwater connections to land and sea, to ensure effectiveness of marine spatial protection and minimize perverse outcomes of changing land-use. Yet, examples of integration across realms are relatively scarce, with most targeting priorities in a single realm, such as marine or freshwater, while minimizing threats originating in terrestrial ecosystems. To date, no study has optimized priorities across multiple realms to produce a spatially explicit integrated conservation plan that simultaneously accounts for multiple human activities at a national scale. This represents a major gap in the application of existing cross-realm planning theory. We present a national scale conservation framework for selecting protected areas using a case study of Papua New Guinea (PNG) that integrates multiple systems and ecological connectivity to account for cross-realm benefits and minimize threats of land-use and climate change. The relative importance of both the forests and inshore reef environments to PNG subsistence and commercial livelihoods emphasizes the importance of considering the connections between the land and sea. The plan was commissioned by the PNG Conservation and Environment Protection Authority and identifies a comprehensive set of priorities that meet conservation targets in both the land and sea. Our national-scale prioritization framework is useful for agencies and managers looking to implement actions given multiple objectives, including watershed management and biodiversity protection, and ensures actions are efficient and effective across the land and sea.

In 2010, under Kiribati’s Programme of Work for Protected Areas (PoWPA), a national ecological gap analysis (GA) was conducted. Its main purpose was to assess how effective the current Protected Areas (PA) network was at achieving Kiribati’s National Biodiversity Strategies Action Plan (NBSAP) conservation targets, and in particular to identify priority areas for the expansion of the PA network and priority actions for improved management of existing PAs. A complementary objective was to identify the key gaps in our knowledge of the country’s biodiversity. The Secretariat of the Pacific Regional Environment Programme (SPREP) and Conservation International’s Pacific Islands Program (CI-PIP) provided technical support to the Kiribati Ministry of Environment, Lands and Agricultural Development (MELAD) to conduct a GA of Key Biodiversity Areas (KBA – areas of high biodiversity and conservation value) in Kiribati, and provided advisory support for its PA network design. The KBA approach was applied at the archipelago (Gilbert, Line and Phoenix Islands) level combining terrestrial, coastal and lagoon habitats. The KBA methodology applied here is based on an international standard methodology that focuses on worldwide threatened species. KBA sites – all designated at the island level - were identified based on the presence of globally threatened species. The KBA sites (Islands) were then prioritized based on three additional criteria including the frequency of species of local concern as identified by the NBSAP, Kiribati Adaptation Plan (KAP) II mangroves, and the PoWPA phase one consultations; areas of expert concern; and a habitat metric based on habitat diversity and numerical analysis of habitat types.
