Analysis of Helicopter Activities in Forest Fire-Fighting

In Southern European countries wildfires are the most natural threat to forests and wooded areas. Over the last decade, public and scientific debates on forest fire management have increased. Helicopters and airtankers are extremely effective fire suppression means, but they are also very expensive. Studies on the improved performance of suppression for the enhancement of firefighting organization are still needed. Consequently to make a plan for the distribution of financial resources to be divided between fire suppression and fire prevention actions in terms of fuel management is not possible. The aim of this study is to compare the helicopter’s forest fire-fighting activity in Tuscany (central Italy) over two periods: between 1998–2000 and 2001–2005 when five and ten helicopters were respectively assigned. For both periods (1998–2000 and 2001–2005) the following were analyzed: the number of forest fires and the burned area with or without helicopter intervention and the position of the helicopter bases in relation to the fire. The results showed that a fleet of 10 helicopters is oversized, in relation to the fire regime of Tuscany, suggesting the need to evaluate a reduction in the fleet. Financial resources may be thus made available for more profitable fire prevention activities, such as, active fuel management. The results also showed where there is the need to improve the helicopter efficiency via the re–management as regards the positioning of their bases.
