Which trees are generally more susceptible to crown fires?

Coniferous trees are generally more susceptible to crown fires due to their structure and chemical composition. These trees, which include species like pines, firs, and spruces, often have needle-like leaves that can be highly flammable. Additionally, conifers typically have a higher resin content, which can ignite quickly and burn intensely.

The canopy of coniferous forests is also denser, allowing fires to spread more easily from the ground through the crowns of the trees. This dense foliage can trap heat and facilitate the upward movement of flames, making crown fires more likely in these species compared to others.

In contrast, deciduous trees and fruit trees tend to lose their leaves in the fall, which reduces the amount of combustible material available during the fire season. As for bamboo, while it can burn, it generally does not have the same crown fire potential as conifers due to its growth form and structure, which does not promote fire spread in the same manner as coniferous forests.
