- (B) Ground fires generally kill large and small trees because of the long and
high temperature heat pulse generated. They release considerable amounts
of nutrients from the burned fuels, destroy many small organisms and fungi
that live in the humus and organic layers, consume seed stored in the litter,
and kill roots in all but deep soil layers. They increase the chance of surface
flow and erosion on slopes, and leave a baked and hardened seedbed that
may prevent rapid revegetation. Increased surface runoff across the exposed
surface may carry away ash and dissolved nutrients, making conditions even
less favorable for plant growth.
