What is the recommended grass height for airfields?

The recommended grass height for airfields is between 7 to 14 inches. Maintaining grass at this height is crucial for several reasons. It helps to stabilize the soil, reducing erosion and enhancing drainage properties, which is essential for the safety of aircraft operations. Additionally, taller grass can better absorb and filter rainwater, minimizing the risk of flooding near runways. Moreover, this height supports wildlife habitats while not interfering with airfield operations, such as maintaining sightlines for pilots and preventing birds from nesting too close to the runways.

While shorter grass heights might seem more manageable, they may not provide the same level of soil protection or drainage benefits. Conversely, allowing grass to grow too high could lead to visibility and safety issues, as well as maintenance challenges. Therefore, the 7 to 14-inch range strikes a balance that supports both the ecological and operational needs of airfields.
