Question

whats another way to say this technique (mechanical thinning) reduces the understorey fuel and stand density, allowing the behaviour of the flame to be better estimated and predicted"

Answer 1

Answer :

Thinning means to remove some plants or part of plants. This is to make room for growth of others and to protect millions of acres of forest that are overstocked and prone to wild fire.

When coming to aspect of preventing wild fire mechanical thinning include tree growth redistribution, tree species regulation, timber harvest etc.

Crown bulk density, surface fuel and crown base height are primary characteristics that determine crown fire potential.

Thinning from below, free thinning, and reserve tree shelter woods have the greatest opportunity for reducing the risk of crown fire behavior or crown flame behavior.

Thinning reduced canopy closure, canopy bulk density and basal area and increased canopy base height. Thinning increased a time lag in fuels and fuel bed depth. Active crown fire potential decreased on thinned units.
