Mobile App Aids Prescribed Burn Management

May 06, 2013

Prescribed fire is a powerful tool that can be used to achieve management goals and manipulate vegetation. When conducting the burn, good communication between the burn crew members is critical for conducting it safely.

A common bit of information that needs to be communicated among crew members is where resources, such as a containment or ignition crew, are located. To facilitate this need, crew members are typically issued a map showing the burn unit and several labeled locations along the burn boundary prior to the burn. Radio communications reference these labeled locations. An example communication might involve an escaped spot fire. The location of the spot fire needs to be communicated to the burn boss. In turn, the burn boss will communicate which resources will respond and where the fire has escaped relative to the nearest labeled point.

A desire to improve on this system led us to ask, "Is there an app for that?" A search for an app specifically designed for aiding in conducting prescribed burns or managing wildfire responses was not successful. One app we found that looked promising, ActInNature, is designed as a hunting app. It is available for iPhone, Android phone or Android tablet, and it has several features we were seeking. The app supports basic (i.e., free) and advanced user (for a small annual subscription) types, the main difference being that advanced users can edit "areas" and share "tags." We used "areas" to define the burn unit and "tags" to mark points of interest, such as ignition sequence points. The app also polls weather data and provides current wind speed, direction, temperature and relative humidity. Advanced users also get three-hour and six-hour temperature and relative humidity forecasts.

Our experience with this app for conducting prescribed burns was generally good. We used the app with one advanced user and the rest as basic users. We set up a group, which allowed us to define areas and tags that only the group could see. This also required users to enter a password chosen by the advanced user. All users could see other group users regardless of the distance between them. Without groups, only users within a 5-mile radius are displayed. This feature is nice because a group member, anywhere in the world, can view progress being made on the burn.

The advanced user digitized the burn unit on the ActInNature website, used their mobile device to add tags at the ignition sequence locations and then shared the tags with the group. The ability of each crew member to see his position on the map was helpful. The ignition crew could quickly confirm where they were, relative to other crew members and the burn boundary. It was easy to adjust the pace for ignition sequences where it is desirable that one ignition crew be igniting at a more downwind position relative to the other crew. It is also reassuring to see where the containment crews are positioned and their progress on patrol. During mop-up, it was useful for the advanced user to add and share tags or spots that needed attention from the crew.

On the downside, the app requires a good network connection (i.e., 3G or better), which is still not available in many rural areas. In addition, the app does not play well with other software. For example, there is no ability to import maps created with other GIS software, and tracks created by GPS fixes of where a user has been can’t be exported. The name of each tag is not displayed – only the symbol – so the user had to select the tag to get the name of a point. Finally, the app accesses GPS often, which means it uses a lot of power. This is not a problem if the device is in a vehicle or is plugged into an external power supply. For users that are on foot, it may be helpful to get an external battery pack to extend the battery life. Perhaps someday there will be an app specifically designed to conduct prescribed burns; in the meantime, the ActInNature app brings some abilities that we would not otherwise have.
