Abstract: A disclosed fire retardant application structure includes an elongated tube comprised of material that is water-porous throughout on one side of the tube and material that is water-impermeable on the remainder of the tube. A disclosed wildfire monitoring and service system includes a satellite-image monitoring computer that is programmed to display a composite map image defining locations of wildfires observed by satellite and multiple separate structures. The system also includes a wireless transmission subsystem that is capable of transmitting a signal from the central location to each of the structures selectively, and, at each of the structures, a fire-retardant application subsystem. Each of the application systems is directed at exterior surfaces of its respective structure and is responsive to a select signal that is transmitted through the transmission system. Variations and methods are also disclosed.
