Forest fires and climate-induced tree range shifts in USA

The fire causes effects of a different nature. In addition to the panic of the people possibly involved, high temperatures can cause burns or carbonization or serious structural damage in the case of elements in concrete, steel or structural wood, with the difference that the duration of the latter can be scientifically calculated and hence the permissible escape time.

Finally, a lot of damage is caused by harmful gases. For example, the formation of CO2 saturates the environment by depleting the presence of oxygen; in the case of incomplete combustion, carbon monoxide can be formed or in other cases the formation of polluting NOx gases is possible.

A fire can be caused by various causes, both natural and man-made for random, lawful or unlawful reasons. They can also be caused by climate change and subsequent global warming. We are seeing how global warming is a direct cause of wildfires, also in USA.

The study: Forest fires and climate-induced tree range shifts in the western US, published on the Nature communications, explained: "Due to climate change, plant populations experience environmental conditions to which they are not adapted.

Our understanding of the next century's vegetation geography depends on the distance, direction, and rate at which plant distributions shift in response to a changing climate. In this study we test the sensitivity of tree range shifts (measured as the difference between seedling and mature tree ranges in climate space) to wildfire occurrence, using 74,069 Forest Inventory Analysis plots across nine states in the western United States.

Wildfire significantly increased the seedling-only range displacement for 2 of the 8 tree species in which seedling-only plots were displaced from tree-plus-seedling plots in the same direction with and without recent fire.

he direction of climatic displacement was consistent with that expected for warmer and drier conditions. greater seedling-only range displacement observed across burned plots suggests that fire can accelerate climate-relate d range shifts and that fire and fire management will play a role in the rate of vegetation redistribution in response to climate change."
