Conservation Science Data and Tools

WWF constantly looks for new opportunities to improve the effectiveness and efficiency of our conservation work. Sharing that newfound knowledge with scientists across the globe is critical to protecting critical species and places.

We share our data with others for valid scientific, conservation and educational purposes. We request that it is properly cited when used and that any modification of the original data by users should be noted.

Conservation Science Tools


Moabi is a powerful online tool for tracking information spatially. It works as a collaborative mapping system that builds a community of users to share, edit, and discuss issues that could affect the sustainability of critical ecosystems.


InVEST is a family of modeling tools that map, measure and value the goods and services we obtain from nature.


The WildFinder application enables users to visualize global distribution of animal species based on the WWF terrestrial ecoregion maps.

Conservation Science Data Sets 

Marine Ecoregions of the World

Marine Ecoregions of the World (MEOW) is a biogeographic classification of the world's coasts and continental shelves. It is the first comprehensive marine classification system with clearly defined boundaries and definitions and was developed to closely link to existing regional systems.

Freshwater Ecoregions of the World

Freshwater Ecoregions of the World (FEOW) provides a global biogeographic regionalization of the Earth’s freshwater biodiversity, including distribution data of freshwater fish, amphibians, turtles, and crocodiles, all available at the ecoregion level.

Terrestrial Ecoregions of the World

Terrestrial Ecoregions of the World (TEOW) is a bio-geographic regionalization of the Earth's terrestrial biodiversity. TEOW uses ecoregions to represent the original distribution of distinct assemblages of species and communities across the globe.

The Terrestrial Ecoregions of the World Base Global Dataset


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.

Global 200

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.

Global Lakes and Wetlands Database

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. The application of GIS functionality enables the generation of a database which focuses in three coordinated levels: large lakes and reservoirs (Level 1), smaller water bodies (Level 2), and wetlands (Level 3).

Smart Infrastructure Planner (beta)

The Smart Infrastructure Planner (SIP) is a GIS toolkit that allows GIS practitioners to evaluate the compatibility of proposed infrastructure and land use developments with essential requirements for the conservation of wildlife and their habitat in a landscape context.

Tiger Conservation Landscape data and report

The Tiger Conservation Landscape dataset and report highlights the remaining tiger lands, the large landscapes of habitat, often anchored by protected areas that are global priorities for conservation.

World Grassland Types

World Grassland Types provide a global biogeographical characterization of the Earth's large scale grassland ecosystems. We developed an ecologically meaningful spatial catalogue of grasslands by combining two systems, the International Vegetation Classification, which describes an eight-level hierarchy of ecosystem expression, and the Terrestrial Ecoregions of the World, a biogeographic regionalization of the Earth's terrestrial biodiversity, to provide a distribution map of global grasslands. The framework provided by our geographical mapping effort provides a systematic overview of grasslands and sets the stage for more detailed classification and mapping at finer scales.
