The opportunity exists to improve intensively managed landscapes (urban and agricultural areas dominated by human activities) through greater engagement of ecologists in the process of ecological landscape design. This approach encourages exploration of multifunctional solutions to meet the needs of growing populations in many areas around the world, while minimizing the negative impacts of human activities on the environment. This is achieved by incorporating theoretical and applied principles from the fields of landscape ecology, agroecology, and ecological design. Multifunctional landscapes can be designed to provide a range of environmental, social, and economic functions, while considering the interests of landowners and users. Here, we propose a process for designing multifunctional landscapes, guided by ecological principles in the following steps: (1) defining the project site and landscape context, (2) analyzing landscape structure and function, (3) master planning using an ecosystem approach, (4) designing sites to highlight ecological functions, and (5) monitoring ecological functions. The development of a framework for ecological design of landscapes demonstrates the importance of a multi‐scale approach for connecting sites to their surroundings, the benefits of a multifunctional design for sustainability, and the value of involving ecologists throughout the entire design process. The ecological design approach is explored for the University of Illinois Field Research Station.

ABSTRACT. We have proposed a framework for transforming landscapes to improve performance by integrating ecological principles into landscape design. This effort would focus on the development of multifunctional landscapes, guided by the rapidly growing knowledge base of ecosystem services provided by landscape features. Although the conventional approach to landscape ecology is based on a model that assumes poor ecological quality in the human-dominated matrix, a review of recent literature reveals important opportunities to improve the quality of the landscape matrix by increasing spatial heterogeneity through the addition of seminatural landscape elements designed to provide multiple ecosystem services. Taken alone, these individual elements might not appear to have a large impact on the environment, but when considered together within the entire landscape, the contribution could be significant, particularly when these elements are intentionally designed to improve landscape performance. Previous attention has focused on the value of large patches of native vegetation for conservation efforts. These efforts have included preserving those areas that still remain, restoring those that once existed, and providing connectivity between them. But great opportunities exist to improve the quality of the matrix by designing multifunctional elements throughout the landscape. Through a synthesis of knowledge in landscape architecture and landscape ecology, we have demonstrated some important applications of the landscape performance framework in urban and agricultural settings. Based on a review of the literature, we have suggested several methods of evaluating and monitoring landscape performance to determine the relative success of a designed landscape.

The environmental impact of loss of natural stream and riparian habitat is of concern throughout the United States and Europe. Environmental impacts related to such activities as channelization of and levee construction along streams and rivers are particularly apparent in the Midwestern United States. The objective of the research presented here was to delineate the extent,

Rainfall runoff of six watersheds was modeled via the Soil Conservation Service runoff curve number model in two ways: conventionally (manually) and via a geographic information system (GIS). Input data (elevation, soils, and landcover) were digital for the latter method. In contrast to previous studies, the GIS was ised for all phases of the modeling process, including watershed delineation and routing of runoff. A comparison between the two methods was consistent with results reported by others and indicates that the use of a GIS is an acceptable alternative to the conventional method for watersheds lacking relatively flat terrain. Given this limitation, the GIS method may prove advantageous over manual methods when study areas are large or numerous, runoff is modeled repetitively, alternative landcover scenarios are explored, or a digital database already exists for the study area.
