Second-order fire effects
n. Fire impacts on the environment that occur after a certain amount of time has passed.
Second-order fire effects, sometimes referred to as “indirect” fire effects, occur after a certain amount of time has passed after a fire (within days of or even up to years after, according to Ryan and Elliot 2005) and are often caused by interaction of fire-caused stress with other factors, such as postfire weather, animal use, or fungal infection. Second-order fire effects include soil erosion, delayed plant and animal mortality, changes in site productivity, plant regeneration, and succession (Reinhardt and others 2001; Ryan and Elliot 2005). Contrast with “first-order fire effects.”
