By Carolyn Ciciarelli, Sarah Mann, Octavia Payne and Alyssa Barrett Global Forest Watch (GFW) enables anyone with a computer and an internet connection to access the best available forest information. But in today’s increasingly mobilized world, people are using smartphones and tablets to connect on-the-go, and we want GFW to go with them. That’s why we have fully optimized the GFW website for your mobile device, putting the most up-to-date information on forests in the palm of your hand. You can now access near real-time maps, country comparisons, data analysis, and crowdsourced stories with the tap of a finger. Just go to on your mobile browser and start exploring! Want to share GFW with your friends? Now you can post GFW blogs, graphs, maps, and more, directly to Twitter, Facebook, Google+, or any other social network using the hashtag #hometownforests. You can also share what’s happening in forests around you by directly uploading text, video, and photos to the GFW map using the Submit a Story feature. Read below to learn more about the new mobile features!

Explore what’s happening to forests near you

Like with Google maps, you can locate your position on the GFW interactive map using the GPS on your device. When you navigate to the map, GFW will automatically geo-locate your position. You can also click the GEO-LOCATE button if you explore the map and want to go back to your current location. (Hint: You may need to turn location services on).

Once zoomed in, you can change data layers and base maps to find out what’s happening near you. Did a tree cover loss alert pop up in the last month? Was a biodiversity-rich area recently cleared? Did a forest become part of a newly protected park? Tap the LAYERS button to turn on different combinations of Global Data, Country Data, and Basemaps and start exploring!

Share what’s happening in your hometown forests

Help us collect more information by submitting a User Story. GFW User Stories aim to create a more complete picture of forest change by linking narratives from people on the ground to data on the map. Whether it’s about illegal activity, threats or conflict in an area, forest conservation or management successes, ground-truthing remotely sensed data, or local expertise, the SUBMIT A STORY button on the homepage makes it easy for you to share your knowledge. (Hint: To make your story pop, give it a descriptive title, like “New road built in protected area in Liberia” and captivating visuals. You can upload pictures or even videos in the media section).

Once you hit SUBMIT STORY, you can find your post on the interactive map by turning on the User Stories layer. Spread the word through your social networks using the share button either on the interactive map or on the story page. Be sure to use #hometownforests to join the conversation!

Analyze tree cover change

Just as on a desktop, you can analyze tree cover change within a country, regional jurisdiction, protected area, concession, or other area of interest. First, turn on any of the forest change layers—tree cover loss, tree cover gain, tree cover loss alerts (such as FORMA or Terra-i), or active fires—within GLOBAL DATA. To view statistics for geographic areas, tap ANALYZE & SUBSCRIBE, then choose a country (required) and jurisdiction (optional) and click ANALYZE.

To calculate tree cover change within other data sets, such as a protected area or concession, simply turn on the data layer you’re interested in and tap on any of the shapes. A box will appear with information pertaining to that polygon along with an ANALYZE button at the bottom. Tap the button to view hectares of tree cover loss or gain, the number of tree cover loss alerts, or the number of active fires within that area. From here, you can export the dataset for your own use by clicking the DOWNLOAD AND EXPORT DATA button. (Hint: this feature is not available for the tree cover loss and gain data sets).

In addition to on-the-fly analysis, you can stay up-to-date on the latest forest change by subscribing to alerts using the SUBSCRIBE button, located next to the ANALYZE button.
