Less than one percent of Arizona’s landscape is comprised of wetlands. Since the late 1800s, streams and wetlands throughout Arizona have been modified or drained, resulting in the loss of more than one-third of the State’s original wetlands.
The most extensive Arizona wetlands are in riparian zones and include oxbow lakes, marshes, cienegas, and bosques. Nonriparian wetlands include tinajas, playas, and caldera lakes. Extreme aridity and seasonally varying precipitation are the climatic characteristics that most significantly influence wetland formation and distribution in Arizona. Recreational use of wetlands provides economic benefits to the State.

Riparian Restoration in Action: Over the past 5 years, private landowner Jim Crosswhite has implemented an extensive conservation plan for his 300-acre ranch in Arizona’s White Mountains. This web site documents his efforts to restore the degraded riparian areas along Nutrioso Creek. This web site would be useful for anyone seeking a comprehensive pictorial history of a restoration project or for anyone looking for an example of how federal agencies can assist with a restoration project.
Riparian Ecosystem Creation and Restoration: Lower Colorado River: Provides three case studies as information about riparian restoration efforts. Includes a table of techniques, successes, and sources. This site provides a good bit of information, though there are no additional contacts provided.
Southwest Center for Education and the Natural Environment (SCENE): Native Habitat Restoration: Briefly discusses this effort to restore native vegetation to urban land. This group may be able to help with additional resources, or may have a project you can get involved in.
