NPS has defined six turf classes to guide parks in setting objectives for turf management and maintenance. This activity describes classes of turf in the National Park System, which vary by function, asset value, species mix and maintenance requirements. Turf may be valued as a facility asset, a natural resource, a cultural resource, or a combination of these, depending upon the situation.
