Acknowledgements The list of in this document was prepared in November 2006 by the Arizona Department of Water Resources (ADWR) in cooperation with plant and landscape plant specialists from the Prescott AMA and other experts. ADWR extends its gratitude to the following members of the Prescott AMA Plant List Advisory Committee for their generous contribution of time and expertise: Dusty Eiker, Mountain West Landscape Resources Charlie Hildebrant, Mountain Path Landscaping Steve Morgan, T. Barnabas Kane & Associates Jeff Schalau, University of Arizona - Yavapai County Cooperative Extension Nichole Trushell, Highland Center for Natural History Harold Watters, Watters Design and Garden Center Cover Photo: Mexican Cliff , Cowania mexicana stansburiana, courtesy of Jim Morgan, Wings of Nature Photography and Recordings

A Resource for Regulated Water Users The use of low water use/drought tolerant plants is required in public rights of way and in other instances as described in the Fourth Management Plan1 . The Low Water Use/Drought Tolerant Plant List was developed to assist regulated water users in selecting landscaping plants that meet these requirements. Following are the sections in the Fourth Management Plan of the Prescott Active Management Area in which the list is referenced: − Section 5-701(4) and (39) Definitions, Low Water Use/Drought Tolerant Plant List for the PRAMA and Water-intensive landscaped area − Section 5-709(A)(3), Individual User Requirements for Municipal Providers and Individual Users, requirements for public rights-of way − Section 6.6.1, Introduction to All Industrial Users Conservation Program − Section 6.6.3, All Industrial User Program Description − Section 6-1301(6), Definitions, Low Water Use/Drought Tolerant Plant List − Section 6-1302(3) and (4), Conservation Requirements − Section 6-1303(A)(6), Monitoring and Reporting Requirements − Section 6-1401(8) and (16), Definitions − Section 6-1402(C)(2), Conservation Requirements for Turf-Related Facilities − Section 6-1403(D)(2)(a) Calculation of Maximum Annual Water Allotment for Turf-Related Facilities − Section 6-1801(5)(a), Definitions − Section 6-1803(3), Monitoring and Reporting Requirements

1 The 1980 Groundwater Code requires the preparation of a series of water management plans for each AMA that include mandatory conservation programs. The proposed Fourth Management Plan for the Prescott Active Management Area was issued on May 14, 2014.

Prescott Active Management Area Low Water Use/Drought Tolerant Plant List

A Resource for Communities, Residents and Businesses The Low Water Use/Drought Tolerant Plant List is a valuable resource for communities, residents and businesses that are interested in conserving water through low water- use landscaping. Plants on the Prescott AMA list meet the criteria of requiring less than a maximum of 12 inches of supplemental irrigation on an annual basis, not including rainfall. This is significantly less than many high water-use plants traditionally grown in the Prescott area. Once established, the plants on the list can be grown in the Prescott area with no to moderate supplemental irrigation.

Request to Waive the Requirement Pursuant to the Fourth Management Plan for the Prescott Active Management Area sections 5-709(A)(3) and 6-1302(4), the ADWR Director may waive the requirement to use plants on the Low-Water-Use/Drought- Tolerant Plant List if the water user demonstrates to the satisfaction of the Director that the plants on the list cannot grow in a publicly owned right-of-way because of high elevation or low light conditions, such as a freeway underpass. Those who wish to request a waiver of the list should submit their request in writing or by email to the ADWR Director including the following information: 1. Description of the location of the publicly owned right-of-way 2. Map showing the location of the right-of-way and the place where plants will be located 3. Botanical and common name of the plant under consideration 4. Description of plant’s water needs, including references Additionally, anyone wishing to add, delete or modify information on the list is encouraged to submit their request to the ADWR Director in writing or email. Waiver and modification requests can be sent to: Lori Cason, AMA Section Arizona Department of Water Resources 1110 W. Washington St, Suite 310 Phoenix, AZ 85007 [email protected]

Prescott Active Management Area Low Water Use/Drought Tolerant Plant List

DEFINITIONS AND KEY TO SYMBOLS Water Use The amount of supplemental irrigation that may be needed on an annual basis under normal precipitation conditions once the plant is established. During an abnormally dry year, it may be necessary to increase irrigation to achieve average annual precipitation in addition to the suggested supplemental irrigation. 1 = 0 – 4 inches 2 = 5 – 8 inches 3 = 9 – 12 inches Note: 0.62 gallons of water is equivalent to one inch of precipitation on one square foot of soil. International binomial system in which the first name represents , and the second, . Additional words may be added to the name to describe further subdivisions. Common Name The non-scientific name by which a species of plant is known. Local Zone Area(s) within the Prescott AMA where the plant will usually succeed and where it should not require more water than the amount of supplemental irrigation indicated under Water Use: G = : 4,400 - 5,000 ft. (average annual rainfall 10 - 14 in.) T = Transition: Pinyon // Woodland – 4,400 - 6,000 ft. (average annual rainfall 12 - 16 in.) P = Ponderosa/Montane: 5,500 – 7,800 ft. (average annual rainfall 16 - 20 in.) Spreads in Cultivated Areas Plant may aggressively spread by , sucker or other method in prepared, irrigated areas. have been purposely left off this list. Seasonal Color The season(s) in which the plant shows color in the form of blooms or foliage. Details regarding bloom and foliage color are included in the “Comments” column. W = Winter SP = Spring SU = Summer F = Fall Evergreen or E = Evergreen – has foliage that persists and remains green throughout the year D = Deciduous – loses foliage at the end of the growing season S = Semi-deciduous – partially loses foliage at the end of the growing season SC = Succulent – has thick, fleshy, water-storing or stems Origin Area or country to which the plant is native N = North S = South E = East W = West C = Central MW = Midwest CA = Mtn = Mountain U.S. = N Am = S Am = South America Mex = Med = Mediterranean Comments Includes notable information about the plant
