Tempêtes et biodiversité : aubaine ou déveine ?

Abstract : This literature review explains that: - Windstorms and consecutive blowdowns appear as positive factors for the biodiversity (specific, structural and ecological diversity), through 1) the succession process occuring in canopy gaps and 2) creation of microhabitats such as uprooting pits-and mounds, dead or decaying wood from snapped or uprooted treefall; - in terms of species loss, impacts are not very important (limited to species whose habitats are small and rare); - impact analysis must take into account previous forest management and the way of harvesting windfall trees. Some guidelines are given in order to take biodiversity into account when harvesting trees after a windstorm.
