In forested ecosystems, insects and pathogens play an important role in ecosystem function, and there is increasing evidence that these organisms are primary determinants of forest structure and composition. Recent research has confirmed this even in sub-boreal forests, where fire was traditionally thought to be the major agent of disturbance and hence the main driver of successional processes. This paper presents a conceptual model of biotic disturbance ecology in sub-boreal forests of central B.C. We also describe how forest management practices can lead to forest health problems by disrupting these ecological processes, and the natural population dynamics of insects and pathogens.
