ATHLETIC FIELDS: In general, weed populations in athletic fields visited by the consultant were relatively low, ranging from approximately 5% to 25% of the total turf area.

Exceptions to this general observation occured at McLane and Cedar fields where the turf had

sustained moderate to extensive damage due to heavy use by adult soccer players during inclement weather. Although high weed populations were not yet evident at these sites, it can be assumed that the many openings in the turf will be colonized by weeds unless remedial action occurs.

Mejor weed species observed in the turf included the following perennials: - Common Dandelion (Taraxacum officinale), English Daisy (Bellis ‘perennits), and: Plantain (Plantago spp.). As the soil warms, no doubt other species, particularly annual weeds, will become ” apparent. : .
