Landscape architecture projects, at all scales, can involve elements which add to our natural resources. These restored areas are increasingly shown to provide “ecological services,” natural functions that enhance natural and human communities in many ways. Restoration ecology activities bring added value to landscape design, both to the site itself and to the region with which any project is ecologically connected.
We will explore restoration ecology concerns and constraints as they relate to restoring ecological structure and function to previously degraded lands. These are often in cities and suburbs where past land-use has removed the historic natural communities. Ecological restoration is also done in less populated areas such as landfill zones, brownfields, abandoned mines and farmlands, and in areas of natural devastation. We will address a series of related questions: What are the processes of functioning plant and animal communities that can be reinstated on damaged lands? What are the constraints to restoring past natural communities (soil, species availability, interactions among species, changed physical environments)? How can restored habitats be incorporated in a synoptic landscape design? What social and political hurdles must be overcome to advance an ecological agenda? These topics will be discussed using relevant ecological literature and examples of landscape architecture site plans and competition proposals where ecology is one of the main thrusts of the design.
Class format will be lectures, class discussions, and some field trips to local sites where ecological restoration has been attempted, sometimes successfully! Students will each do a model ecological restoration design, based on an actual landscape, to practice the types of analyses and interventions needed to incorporate natural structures and functions into a landscape design. Prerequisites should include the Core III course in ecology, or a similar background in modern ecology and habitat structure. Readings will be in the ecological and landscape architecture literature.
