Why might recently exposed forest-edge trees be more prone to failure?

Recently exposed forest-edge trees are more prone to failure due to heightened wind exposure. When trees are part of a dense forest, they benefit from the shelter provided by surrounding trees, which reduces the impact of wind forces. However, when these trees are suddenly exposed at the edge after adjacent trees are removed or die, they face increased wind pressure on their canopies.

This exposure can create a significant imbalance, as the tree may not have been previously adapted to withstand such forces. Additionally, the trees may experience increased sway and stress, which can lead to structural weaknesses over time. This vulnerability to wind is particularly crucial during severe weather events, where strong gusts can push the trees beyond their limits, resulting in failure.

The other factors mentioned in the choices, while they may influence tree health, do not specifically address the immediate impact of wind exposure on recently exposed trees.
