The Global 200 identifies a set of the Earth's terrestrial, freshwater, and marine ecoregions that harbor exceptional biodiversity and are representative of its ecosystems. The Global 200 includes 238 ecoregions, comprised of 142 terrestrial, 53 freshwater, and 43 marine priority ecoregions.

HydroSHEDS provides hydrographic information via data layers to support watershed analyses, hydrological modeling, and freshwater conservation planning at a quality, resolution, and extent that had previously been unachievable in many parts of the world.

This guide is designed to help InVEST users select the most appropriate types of scenarios and methods when engaging stakeholders in the InVEST process. The guidance draws heavily on case studies where the provision of ecosystem services under alternative scenarios was evaluated using InVEST. The document highlights key issues and questions and provides tools, references and resources for readers who want to learn more.

This primer is a 12-page summary of Developing Scenarios to Assess Ecosystem Service Tradeoffs: Guidance and Case Studies for InVEST Users, which highlights case studies and guidance on developing scenario maps for the InVEST tool.

This booklet provides a summary of the ninth edition of WWF’s Living Planet Report (LPR) documenting the “state of the planet.” Projections estimate that at current rates of consumption, by 2030 we will need the equivalent of two Earth’s to sustain our annual demands. This report suggests how this is happening, and how we can effectively manage, share, preserve and restore natural capital (biodiversity, ecosystems, and ecosystem services) through WWF’s “One Planet” perspective.

This WWF report brings together a variety of quantitative information and on the current state of global biodiversity and human impact on nature. Confronting the fact that people are using 50 percent more resources than the Earth can provide, this report summarizes this information and suggests changes in action to slow and reverse current trends.

This BioScience journal article presents the idea of Marine Ecoregions of the World (MEOW), a hierarchical global system of 12 realms, 62 provinces, and 232 ecoregions. MEOW offers a higher level of organization of marine life and is a critical planning and pattern analysis tool for conservation organizations like WWF.

The Global Lakes and Wetlands Database combines data from the best available sources for lakes and wetlands on a global scale at three coordinated levels - large lakes and reservoirs, smaller water bodies, and wetlands.

This guide is based on emerging innovations in designing and implementing conservation across various landscapes. It focuses on refined conservation planning following an ecoregion vision with a focus on biological prioritization and key elements of stakeholder engagement and negotiation.

This article, from the Annals of the Missouri Botanical Garden, explains the idea behind “The Global 200” – 238 ecoregions that represent the world’s most unique, irreplaceable and biologically diverse terrestrial, freshwater, and marine regions for easy analysis and comparison. By highlighting the most important biological characteristics of a certain region, the Global 200 serves as a tool for more detailed analysis.

This is a one-page, color world map identifying key terrestrial ecoregions.
