What predisposes trees to other stress factors in flooded conditions?

Root suffocation and death are critical factors that predispose trees to other stressors during flooded conditions. When soil becomes saturated with water, the air spaces in the soil are filled, leading to reduced oxygen availability for tree roots. Roots require oxygen to carry out respiration, which is essential for their growth and functioning. When suffocated, roots cannot effectively absorb water and nutrients, weakening the tree.

As a result, the tree becomes more susceptible to a variety of stress factors, such as diseases, pest infestations, and further physiological stress. This weakened state can lead to increased vulnerability to other environmental challenges, including drought or extreme weather events, as the tree's overall health and resilience are compromised.
