The research program of historical ecology

Historical ecology is a new interdisciplinary research program concerned with comprehending temporal and spatial dimensions in the relationships of human societies to local environments and the cumulative global effects of these relationships. Historical ecology contains core postulates that concern qualitative types of human-mediated disturbance of natural environments and the effect of these on species diversity, among other parameters. A central term used in historical ecology to situate human behavior and agency in the environment is the landscape, as derived from historical geography, instead of the ecosystem, which is from systems ecology. Historical ecology is similar to nonequilibrium dynamic theory, but differs in its postulate of human-mediated disturbance as a principle of landscape transformation. Such disturbances counterintuitively may involve anthropogenic primary and secondary succession that result in net increases of alpha and even beta diversity. Applied historical ecology can supply the reference conditions of time depth and traditional knowledge to restore past landscapes.
