nation’s domestic water use is directed toward the landscape in the form of irrigation ( DeOreo et al., 2016 ). In places such as central Florida, this amount can exceed 60% ( Haley et al., 2007 ) and in Florida, the adoption of water conservation

. Thus, the urban landscape is one area that is a target for water conservation. This might be due to two reasons: 1) the urban landscape is highly visible to the public and is apt to be regulated, and 2) increasing urbanization is favoring a shift in

Water conservation is making journal headlines nationwide because of drought, contamination, pollution, and over development. While the idea of xeriscaping began in the Western United States where landscapes can be truly dry, many water-saving principles apply to the Southeast, where home moisture problems and pest problems associated with moisture are a major problem. A year of drought maybe followed by three years of plentiful rainfall, and conditions are significantly different from the semi-arid regions of the country to which most of the present literature on water conservation is directed.

The purpose of this project was to provide information on water conservation to designers, landscape industry personnel, and homeowners in the Southeast. This was done by compiling recommendations based on research being conducted by professionals in building science, forestry, horticulture, entomology and landscape architecture.

An educational tool addressing the pressing national problem of water conservation with a regional emphasis, this project was designed to help readers increase landscape water efficiency by 30 to 50% while lowering maintenance costs and insuring greater survivability of landscape plants in times of water shortage. Through careful planning and design, economically attractive and aesthetically sound water conserving landscapes can be created.

The San Pedro River has been impacted by continued growth of Fort Huachuca Military Base. The San Pedro River, a riparian-migratory area, has had continuous water flow but now has intermittent water flow. The cause is cones of depression in the aquifer due to domestic well pumping. The aquifer is recharge with water from the river. Cooperative Extension has implemented Resource Conservation Audits for landowners in the lower San Pedro Valley. Also, outdoor classrooms are being constructed at three schools to educate children and community members. The goal of these programs is to educate landowners on water conservation through the use of native and adapted drought-tolerant plants, xeriscaping, irrigation efficiency, water harvesting, soil erosion, and composting. Site visits help landowners identify opportunities to reduce water use. Research-based informational brochures have been produced so landowners can plan and implement water-saving techniques on their properties. This program has been implemented using six members of the Border Volunteer Corp., part of Americorp program.

A survey instrument was designed to determine public opinion on water conservation, water conserving landscapes, the use of native plants in landscapes, home irrigation systems, and the performance of five Texas native plant species [pink evening primrose (Oenothera speciosa); prairie verbena (Verbena bipinnatifida); red yucca (Hesperaloe parviflora); ceniza (Leucophyllum frutescens); and ruellia (Ruellia nudiflora)] grown in low water use landscapes in the semiarid Southwestern United States. On six occasions during the 1999 growing season, participants viewed landscapes and participated in a survey. Survey data indicate that over 90% of respondents thought water conservation was important to the state of Texas. A majority of participants however, believed water conserving landscapes to be expensive to maintain and not aesthetically pleasing. The survey revealed 79% of participants would use native plants if native plants conserved water, and 86% of participants would use native plants if native plants were attractive. Chi-square approximations revealed participant's opinions regarding water conservation and home irrigation systems were influenced by education level and amount of time they participated in weekly horticulture activities. In an open-ended question, participants indicated flowers and healthy leaves were characteristics indicating a plant was performing well. Throughout the year, species in flower received higher ratings than nonflowering species.

water quality issues are getting worse over time and are significantly affecting the future of green industries (greenhouse, nursery, landscape). Water conservation can be achieved by irrigating greenhouse and nursery crops, and landscape plantings with
