Forest Watcher is a mobile application designed to bring the dynamic online forest monitoring and alert systems of Global Forest Watch (GFW) offline and into the field. Forest Watcher allows users to easily access GFW’s forest change data on any mobile device, navigate to areas of detected change, and collect information about what they find, regardless of connectivity.

This app provides an affordable and easy-to-use solution to quickly identify areas for patrols or field investigations; collect evidence about forest changes from the ground; use data collected to make evidence-based management and conservation decisions, and validate remote sensing products in the field.

- Designated area(s) of interest to monitor

- Overlay contextual layers, such as Protected Areas and Timber Concessions, or upload other datasets
- Investigate alerts in the field and collect information (including GPS points and photos) through customizable forms
- Review, analyze, and download data collected with the app

Amazing app for forest monitoring

This app brings GFW to your phone to make monitoring forests easy and efficient. It's really helpful to see deforestation and fire alerts in my area and be able to submit reports with data from patrols. Great job WRI!

Great offline tool for monitoring forests

Same powerful data as Global Forest Watch, but in a mobile app with clean interface, and easy to use.

Great app by WRI

WRI has built a meaningful and powerful tracking tool. It's great to be able to track forest progress (or deforestation ).
