The Altar Valley Conservation Alliance (AVCA) supports stewardship projects that enhance grassland production and diversity, and improve watershed function by increasing water infiltration, enhancing soil stability, and promoting native vegetation diversity and productivity.  In 2019, AVCA partners began the development of a Watershed Restoration Plan to guide stewardship and projects in the valley, and open doors to new funding sources and partnerships. The project was funded by a 2-year grant (extended to 3 years due to Covid-19) from the US Bureau of Reclamation WaterSMART program, awarded to the Altar Valley Conservation Alliance and with funding from the Pima County Regional Flood Control District.  The plan describes stewardship practices and tools and a series of high-priority projects that maximize positive impacts on the land and in the community. Most projects will address two major themes: 1) Hydrology issues including channel incision of the Altar Wash mainstem and upland tributaries; and 2) Vegetation issues related to brush encroachment from mesquite and other woody species.

The purpose of the restoration plan is to: clarify shared goals, determine the best stewardship practices to achieve those goals, describe where and how to deploy these practices, and build a strong foundation from which to seek appropriate project partners and funding.  The plan is an accessible resource that supports efforts by those living and working in the Valley. It is non-binding and is designed to be available to willing landowners and managers. More specifically, the plan:

• Provides a clear, unified source of guidance to collaborative parties, focused on shared goals
• Devises solutions to complex problems in the Altar Valley, and promote continuance of effective practices
• Creates a “toolbox” of information and resources on stewardship practices, permitting, monitoring, and other topics
• Identifies and prioritizes restoration projects important to accomplish across the valley over the next 25 years
• Includes conceptual plans for potential projects

Recommended stewardship practices include: brush removal using various methods, prescribed fire, managed grazing, erosion control and floodplain enhancement structures, water harvesting from ranch roads, and more.

Process

In 2019, partners of the AVCA began developing the Plan to guide stewardship and identify priority conservation projects in the Valley, and through this process open doors to new funding sources and partnerships. The project was funded by a three-year grant from the US Bureau of Reclamation’s (BOR) WaterSMART program, awarded to the AVCA and matched by the Pima County Regional Flood Control District (PCRFCD).  The Plan was developed by the Watershed Working Group (WWG), a broad group of individuals, organizations and agencies that had worked together for years on collaborative issues.  To write the plan, the WWG formed Technical Teams to focus on four major topics of interest: Vegetation, Hydrology and Erosion, Community Resources, and Wildlife.  The planning process was facilitated by Southwest Decision Resources (SDR), an independent firm that previously supported collaboration in the Altar Valley for many years.  The conceptual project plans were supported by the engineering firm JE Fuller Hydrology & Geomorphology, Inc. (JE Fuller), and mapping and geospatial analysis was provided by The Quiet Creek Corporation (Quiet Creek).  The AVCA convened the WWG, engaging local landowners, agencies, non-profit organizations, and university scientists in the development of this plan.

Partners

The plan was developed by a collaborative Watershed Working Group (WWG), a broad group of individuals, organizations, agencies, and technical teams focused on Vegetation, Hydrology and Erosion, Community Resources, and Wildlife.  The planning process was facilitated by Southwest Decision Resources, an independent firm that has supported collaboration in the Altar Valley for many years. The hydrology conceptual project plans were written by the engineering firm JE Fuller Hydrology and Geomorphology, and mapping and geospatial analysis was provided by The Quiet Creek.  Project staff engaged landowners and/or managers in discussion of goals and projects and sought their involvement as willing landowners. The Plan is designed to be updated regularly and reflect the needs of the Altar Valley.
