Greenways have historically played a significant role in the development of green infrastructure design and planning. As one of the many components of greenways, vegetated buffers along urban and suburban watercourses are typically well-suited for recreational uses such as biking, walking trails and wildlife-viewing. However, development pressures in cities and suburban environments can lead to fragmented and redirected watercourses to accommodate other land uses. In some cases, unplanned access increases erosion and loss of vegetation and potential wildlife habitat in these areas. It is critical for future conservation of these natural and restored areas that appropriate access be explored. This paper presents two case studies of watercourse-associated greenway development in two distinctly different regions, arid and temperate, and compares the approaches and contributions to green infrastructure in their respective regions.
