74 GOLF COURSE MANAGEMENT 04.19 Maggie Reiter, M.S. Kai Umeda, M.S. Worku Burayu, Ph.D. Establishment of low-maintenance, naturalized grasses and forbs for turf replacement in California and Arizona Superintendents must consider a number of factors, including their location and goals, when selecting naturalized grasses and forbs for turf replacement on golf courses. Golf course superintendents are facing in- creased pressures to reduce inputs of water, fertilizer, pesticides and labor while main - taining turfgrass quality and playability. Al- though some of these pressures are environ- mental, such as poor water quality or lack of water availability, others are social, including legislative restrictions, economics and in - creasing desire to conserve natural resources. To address these demands, golf course super - intendents are interested in using alternative plant species that perform well under ultra- low-input management. e rough makes up the largest percentage of maintained golf course turf and is often the most practical turfgrass to replace on a large scope, espe - cially in rough areas that are seldom in play and not worth the inputs required for main - tenance. Alternative grass or forb species exist that could provide a minimal-input, naturalized area without impairing playing conditions. However, there are significant unknowns associated with the adaptation and establishment of alternative grass spe - cies, including plant material selection, seed- ing rates and irrigation requirements.
