How the fires start may vary from region to region, but a major reason for an increased intensity of wildfires is shared: wet winters. A wet winter nourishes grass and other ground vegetation that is the primary fuel for wildfires. When a wet winter is followed by a dry spring and summer and high winds, it’s usually a recipe for a difficult fire season. For those countries beginning to experience more frequently wetter winters, there is a window of opportunity to integrate advanced wildfire detection and containment technologies before wildfire risks intensify. Dryad provides ultra-early detection of wildfires as well as health and growth-monitoring of forests using solar-powered gas sensors in a large-scale IoT sensor network.
