Lessons learned from arson wildfire incidence in reforestations and natural stands in Spain

Wildfires are currently considered the major threat to forests in Mediterranean countries. It has been implied that a large percentage of arson-caused fires in Spain are connected with the extensive reforestation programs implemented between 1940 and 1970. However, no consistent studies have been co...

Reforested stands presented higher fire incidence than natural stands mainly for productive species like Pinus pinaster Ait.
