The Forest Watcher mobile app brings the online forest monitoring and alert systems of Global Forest Watch offline and into the field. By setting up an area to monitor and downloading deforestation and fire alerts, you can take this information with you to help investigate and report what you find, regardless of Internet connectivity. There is also a web version of the application which allows you to view and collect reports, create and assign areas of interest, and upload your own contextual data. This application is useful for earth defender communities who wish to monitor and report on land use changes or environmental threats taking place in their land. It is frequently used in tandem with the Global Forest Watch platform or MapBuilder, which are also covered in this guide.
