More than 4,400 terrestrial and freshwater species are threatened by changes in the fire regime. While many species are at risk by the increased frequency and intensity of fire, its suppression can be harmful to some life forms and ecosystems.
Creating less flammable landscapes would as much as halve the area expected to be affected by fire in the next 30 years28 de August 2020Adriana Clivillé
Using mathematical models, a joint Spanish and Portuguese study has shown that altering the landscape, so as to reduce vegetation density and combustibility for example, and promoting farming activities of high natural value would drastically reduce the amount of land damaged by fire.
The use of the term 'resilience' has been extended. But success entails risks. When dealing with complex concepts encapsulated in a word, the risk translates into confusion. It is therefore worth entertaining the passage and meditate for a while.
Anoia and Bages suffered a large forest fire in July 2015, which burned 1,235 ha. Areas of Aleppo pine that had been thinned previously are recovering better than non-thinned areas in terms of resprouting species of trees and shrubs. The regeneration of the Aleppo itself has been more modest and sparse, but they can be found throughout the burnt area.
A CEED (Centre of Excellence for Environmental Decisions) Research Fellow has been recently awarded one of the five Victorian Postdoctoral Research Fellowships. He will travell to Spain to study the threat of fires to biodiversity at the CTFC (Forest Sciences Centre of Catalonia) and CREAF (Centre of Ecological Research and Forestry Applications).
A recent study from CREAF, CTFC, and the UAB warns that if the continuity of forest vegetative cover over large parts of the territory is not reduced with urgency, catastrophic fires will become more and more common. Allowing some spontaneous fires to burn under controlled conditions could help to resolve this problem.
A new model of landscape evolution, developed by a group of Catalan and Canadian researchers, identifies that the ability to extinguish fire is essential in the explanation of the fire patterns in Catalan territory. The model also shows that, if current climate trends continue, the burned area could increase by more than 60% in the next 20 years.
