I don't know if your kidding or not? Dictionary ought to define it as the bane of existence. It's an old world sod forming cold season grass. Most common lawn grass. Hyper competetive, carries a symbiotic endophyte that causes health issues in livestock but provides a resistence that helps the dang fescue through times of stress. Easily out competes the natives, and with it;s long growing season was championed by the USDA in the 60's as a miracle plant, allowing almost year round grazing with little or no maintenence or effort. Another example of importing something with limited benefit and a great deal of negative impact. Like Kudzu, House Sparrows,Starlings, purple loose strife, and most recently zebra mussells. Back to fescue, it causes a thick mat of monoculture grass which is unusable to nesting or brooding quail and most ground nesting birds. Can't move through it easily, not conducive to insect number or variety, crowds out any useful grasses even with agressive management to the contray. Increase in fescue will parallel the decline of quail, in an almost perfect graph. If you don't know what it is, bless you, it probably hasn't made it's way to you yet, or maybe if your real lucky it can't adapt to your area.
