Roadside Ecosystem Study (NA-98-0331)

Development of working vegetation models and management strategies to create and preserve public landscape spaces in our transportation corridors.

The Roadside Ecosystem Study resulted in the development of working vegetation models and management strategies to create and preserve public landscape spaces in our transportation corridors that are biologically diverse and environmentally sound. The horticultural success and economic viability of these models was documented and continues to be monitored. Concepts advanced by this project are being implemented with Delaware Department of Transportation (DOT) support.

A 'Vegetation Concept and Design Manual' has been developed for the State DOT to guide road design professionals and community members in matching vegetation regimes to transportation rights-of-way. A key aspect of this manual is an illustrated step-by-step site evaluation process using an innovative visual priority matrix as well as physical site evaluation methodology.

A statewide survey and focus groups coordinated by University of Delaware Cooperative Extension confirmed public acceptance of tested vegetation regimes. The study identified the importance of education with respect to roadside enhancement proposals, especially with naturalistic styles. Color and order are highly valued aspects of roadside scenes,but do not necessarily equate with highly manicured styles. Mowed turf was rated poorly for attractiveness. The concept and design manual serves as the basis for a public education campaign to promote the value of ecologically sustainable and diverse highway plantings.
