Originally, research focused solely on the usefulness of water hyacinths in the treatment of effluent. However, recent studies have utilized a variety of native and locally tolerant plants, including shrubs and trees, to compare the effect of both potable water and effluent on the plants under study. Visitors to CERF are treated to an array of cottonwood, willow, ash, sycamore, desert willow, cattail, bulrush, and other species of plants in various stages of growth in the gravel-filled raceways. As the wetlands facility has developed, the increase in vegetation has created a natural habitat for wildlife, including mammals, reptiles, birds, and insects. In an effort to duplicate the most natural environmental conditions, researchers encourage the presence of animals and, as much as possible, avoid interfering with wildlife drawn to the facility.
Tours are by appointment only.
For 30 years, its facility has investigated and showcased opportunities for establishing a more resource-conscious and sustainable relationship with the desert environment. The Laboratory maintains more than 63,000 square feet of offices, laboratories, and controlled experimental facilities on-site. No reservations are required. The tour is lead by lab scientists and includes a history of the lab, a review of current projects, and a walking tour through the facilities. Walking shoes are suggested, because the tour goes through greenhouses with sand floors.
