This paper analyzes the relevance and interconnection of two forms of historicity in ecological restoration, namely historical fidelity and path dependence. Historical fidelity is the practice of attempting to restore an ecological system to some sort of idealized past condition. Path dependence occurs when a system can evolve in alternative local equilibria, and that the order and timing of the events that follow from the initial state influence which equilibrium is reached. Using theoretical examples and case studies, the following analysis (...) shows that path dependence can seriously impinge the feasibility of historical fidelity, thus reinforcing the idea that restoration ecology needs to move away from a rigid reliance on historical fidelity and is sometimes justified to endorse an interventionist agenda. Yet, contra recent criticisms, I argue that ecological restoration, directed by prudential and evidence-based reasoning, should maintain historical fidelity as one of its guiding objectives.

El objetivo principal de este artículo se encuentra orientado a elucidar, desde una perspectiva histórica, cierta influencia que la problemática ambiental tuvo sobre la ecología disciplinar. Para ello, se analizó el periodo que va de la década de 1960 hasta la actualidad. Dos resultados centrales se desprendieron del análisis propuesto y ambos se encontraron mediados por un saber ambiental que emergió junto a la problemática ambiental. El primero, constata una serie de transformaciones fenomenológicas (con el establecimiento de nuevos patrones ecológicos), (...) epistemológicas (con la incorporación de la noción de escala y de la teoría jerárquica) y metodológicas (con la consolidación de los experimentos de mensuración) sobre la matriz de la ecología. El segundo, se vinculó con una continuidad sincrónica entre la problemática ambiental y la ecología disciplinar. Continuidad rastreada por el reconocimiento de una problemática ambiental de orden global. The main objective of this article is to elucidate, from a historical perspective, the influence that environmental issues have had on the discipline of ecology. To this end, the period from the 1960s to the present was examined. The proposed analysis revealed two main results; both were found to be mediated by environmental knowledge that emerged along with environmental issues. The first refers to a series of phenomenological (establishing new ecological patterns), epistemological (incorporating the notion of scale and hierarchical theory) and methodological (consolidating of experiments involving measurements) transformations over the ecology matrix. The second was linked with a synchronic continuity between environmental issues and the discipline of ecology. This continuity was traced by the recognition that environmental issues have global impact. (shrink)
