  1. REBIOMA maps


    Partners: Wildlife Conservation Society, University of California, Berkeley

    This map application shows a snapshot of biodiversity data derived from species distribution models hosted on the REBIOMA data portal. This is a prototype of mapping and data interaction tools we are working to integrate on top of the data portal.

    The is a simple application written in Rails, html and javascript, with a CartoDB hosted spatial table, backed by a postgres database on Heroku. The code is available on GitHub.

    We model species distributions for three eras from public and private occurrence data uploaded by many individuals and partner institutions.

    After validation and review of the occurrence data by teams of taxonomic experts, we use MaxEnt to model species distributions from the database, using forest cover and WorldClim climate data for 1950, 2000 and 2080 as predictors. For 2080, we assume that forest cover remains the same as it was mapped in 2000 (an optimistic scenario). We then apply a presence threshold to each model, and use the result to build the map of species richness and a species list for each era, shown here. Richness and species lists are calculated on a 5x5 km grid.

    REBIOMA is a joint project Wildlife Conservation Society Madagascar, and the University of California Berkeley with support from the MacArthur Foundation and the JRS Biodiversity Foundation. For more information, please see the project page, data portal, and help pages.

  2. REBIOMA data portal


    Partners: Wildlife Conservation Society, University of California, Berkeley

    The mission of the REBIOMA web portal is to serve quality-labeled, up-to-date species occurrence data and environmental niche models for Madagascar’s flora and fauna, both marine and terrestrial. REBIOMA is a project of WCS-Madagascar and UC Berkeley. The REBIOMA Data Portal address is

    REBIOMA serves species occurrence data for marine and terrestrial regions of Madagascar. Following data upload, data is automatically validated against a geographic mask and a taxonomic authority. At upload, data providers can decide whether their data will be public, private, or shared only with selected collaborators. Data reviewers can add quality labels to individual data records, allowing selection of data for modeling and conservation assessments according to quality. Data users can query data in numerous ways (see simple and advanced search). REBIOMA also produces and serves environmental niche models for current and future climate scenarios for terrestrial and marine species.

  3. Biodiversity database and monitoring system, The Gambia


    Clients: Department of Parks and Wildlife Management, The Gambia; The Global Environment Facility (GEF); WWF-Senegal.

    The Gambia’s coastal and marine biodiversity is nationally and internationally significant and provides important ecosystem services to local communities. Although a set of conservation areas is currently in place to safeguard this heritage, biodiversity resources in the region face considerable and increasing pressure from a human population expected to grow at an annual rate 3-4% into the foreseeable future and nearly double to 2 million people by the year 2025.

    Coastal systems are under particular threat: 91% of The Gambia’s population lives within 100 km of the coast, and these coastal populations are increasing in number and density. Population density in The Gambia is already among the highest in sub-Saharan Africa. It is well known that coastal ecosystems (e.g. mangroves, wetlands) provide important direct and indirect environmental services to people, supporting fisheries and preventing coastal erosion for example. Human activities having direct and indirect impacts on these resources are also well documented. For example, urban encroachment, industrial development, increasing agricultural activities, fuelwood extraction and over-harvesting have all been cited as threats to the Tanbi Wetland Complex, a recently designated Ramsar Site within the vicinity of Banjul in the Western Division. In short, coastal resources are finite. As human population grows in size and density in The Gambia’s coastal zone, it will likely increasingly impact the coastal resources on which it increasingly depends.

    Protecting The Gambia’s coastal resources so that they continue to provide services to people over the long term without degradation will require active and balanced management of the ecosystem. Biodiversity – the sum of biological resources in the coastal zone, from mangroves to local freshwater fish – is the immediate source of resources on which people depend. Effectively managing these resources, therefore, requires consistent, organized and relevant data to measure status and trends of biological resources over time.

    To this end, we have designed a biodiversity monitoring system and database with several main components. These are:

    • Focal targets, such as marine turtles, selected through a consensus-driven process
    • Quantitative conservation goals for each focal target
    • Indicators designed to quickly assess and communicate progress towards goals
    • Monitoring programs to collect necessary data and measure progress over time
    • Monitoring databases and other technical tools, such as GIS and remote sensing, for data analysis and storage
