Washington, April 22 : A new study has suggested that in some cases, changes in the types of plants growing in an area could override the effects of climate change on wildfire frequency.

Philip Higuera of Montana State University and his colleagues show that although changing temperatures and moisture levels set the stage for changes in wildfire frequency, they can often be trumped by changes in the distribution and abundance of plants.

Vegetation plays a major role in determining the flammability of an ecosystem, potentially dampening or amplifying the impacts that climate change has on fire frequencies.
