Restoring Arroyos and Preventing Landscape Erosion
Since 2010, the Cienega Watershed Partnership (CWP) has worked with organizations to restore landscapes within the watershed, especially with the Bureau of Land Management for the Las Cienegas National Conservation Area. Soil and nutrient conservation and water retention are critical components of habitat quality and overall watershed health. Restoring washes and arroyos and preventing erosion and sheet wash are top priorities with the goal of presenting erosion and down-cutting annually from carrying acres of rich sediment from the valley’s uplands to Cienega Creek and out of the ecosystem. When this happens, soils and habitat structure are compromised, challenging native vegetation and the wildlife that depend on it, while actually lowering water tables and draining the entire system.
Volunteer Programs and Education
The earliest work involved CWP partnering with Sky Island Alliance to train individuals in restoration techniques and to enlist volunteers in making improvements. Under the guidance of Bill Zeedyk and Trevor Hare, workshop participants learned about water moving across the landscape, how to understand impacts, and basic practices using various kinds of techniques to prevent damage. Over $30,000 in volunteer hours were donated.
The Youth Engaged Stewardship program (YES!) concentrates on the Gardner Sacaton Flats, where vegetation communities have expanding bare earth issues. From 2014 to 2016, youth have transplanted soils, added erosion structures, and more recently, transplanted crypto bio-crust to stabilize soils. This work will continue in 2017.

Partnering to Create a Restoration Plan
Since 2015, the Cienega Watershed Partnership has enlisted Watershed Management Group’s (WMG) help in creating a restoration plan to begin the process of revitalizing and conserving Cienega Creek. We will use the knowledge and experience we have gained through our work in the region and hit the ground running in the Cienega Creek watershed.
Why Cienega Creek? The creek is located in one of the Tucson basin’s rare shallow groundwater areas, and fits WMG’s goal of restoring our heritage of flowing rivers. More than 280 native species, several of them threatened or endangered, make their home here. Both riparian animal and plant species abound here, but unfortunately, so do threats to the ecosystem. The creek’s banks are suffering from erosion and an influx of non-native invasive species that choke out important native species. The good news is that both individual property owners and local and federal agencies are passionate about creating a brighter future for the watershed. And through a stakeholder prioritization process, WMG is seeking input from these stakeholders in workgroup meetings where we ask folks what’s important and how we protect it. This process is producing a guide to where and how we initiate conservation action and we will soon be out there doing it!
