Research Design Connections
Studies examine tools for stormwater management, forestry management, and pedestrian safety.

By Sally Augustin

Landscape Architecture, in partnership with the web-based newsletter and daily blog Research Design Connections, uses this column to report current research of interest to landscape architects from a wide array of disciplines. We welcome your comments, suggestions about future topics, and studies you have encountered in your own practice.
