Are our forests full of biochar?

If forest fires burn organic matter, and biochar is created by burning of organic matter shouldn’t forest soils be full of biochar? Not exactly. There is a difference between the burnt product of wildfire and biochar. Forest fires do produce charcoal, but while both charcoal and biochar are types of pyrogenic carbon, they’re not quite the same thing… Forests in Alberta have been affected by the mountain pine beetle, leaving behind dead trees that act as easy fuel for fires. These dead, dry trees are extremely flammable. The Canadian government has looked into using these dead trees as biofuels and some companies do use them to create biochar. Another source of organic matter for biochar is the material removed from forests as part of fuel management… Both of these methods help manage wildfire and could potentially increase the carbon sequestration of forests if the resulting biochar was added back into the forest’s soil.
