04.19 GOLF COURSE MANAGEMENT 79 • Alternative plant species that perform well under ultra-low-input management can help conserve resources. • In California, we examined low-mainte- nance grasses for grass density, height and NDVI measurements. • In Arizona, grasses were examined for uniformity, coverage and greenness. • Uniform irrigation was required to obtain even seed establishment and full plot area coverage. • Superintendents should consider how stand height and plant density can impact playability. The RESEARCH SAYS ized plant species as drought-tolerant plants; however, superintendents should be aware that consistent irrigation is necessary for suc - cessful establishment. Previous research has demonstrated lack of water is often a cause of seedling mortality in native and naturalized plants (5). In terms of stand height, super - intendents should consider how vegetation can impact playability. For example, in play - able areas, higher stand height can obstruct visibility of golf balls, and plant density can hinder the ability to find golf balls and, thus, affect pace of play (1, 2). Continued research replicated over loca - tions and seasons is needed to obtain more reliable information about each species' de - sirable growth characteristics, required in- puts and integrated pest management re- quirements. Funding California research was funded by the United States Golf Association. Arizona re - search was funded by the United States Golf Association, United States Department of Agriculture Specialty Crop Block Grant and the Horticultural Research Institute. Literature cited 1.
