Area Landscape Restriction Plan, Maintenance. Weed Management Plan. The 270-acre golf course interim open space area (Tract J) integrates a return to the agricultural context from which the golf course was originally developed, along with additional amenities for River Rim residents. The long-term concept is to maintain approximately 50% of the open space area in native grasses, and allow for establishment of the native shrub community, similar to the processes observed on neighboring CRP fallow croplands. The native grass/shrub community is a landscape detail that is borrowed from the final landscape design of the golf course. Native cover will be maintained throughout the golf course, with the ultimate goal of cutting tees, greens and bunkers out of the native grass/shrub areas, while preserving the outlying native plant communities in perpetuity. For this reason a native grass seed mix has already been developed by a specialist, derived from the seed-basis of native plants in proximity to the River Rim PUD project area (Table 1). Areas will be seeded with this mix, fertilized as needed, and areas reseeded as necessary to achieve a continuous native grass coverage.

The ultimate cultivated crop will be determined by the lessee; however, either dryland wheat or barley can be anticipated. Other portions of River Rim Open Space are currently managed in this way, with lessees maintaining open space as developed agricultural plots yielding crops. From the standpoint of noxious weed eradication, either application will provide a means to curb the invasive species that have taken hold in areas of the golf course. The best long-term control technique for reducing exotic plant invasions is to establish diverse and continuous native vegetative cover. However, spot herbicide spraying of weeds will be necessary for several years prior to establishment of native plant communities. A planted cover crop,...
