Centennial Airport in Colorado is using a herd of goats to clear dense vegetation from its grounds [1].
This biological approach to land management addresses critical safety concerns by reducing the fuel available for wildfires and eliminating habitats that attract dangerous wildlife to active runways [1], [2].
The airport has deployed 322 goats to handle the task [1]. Other reports describe the herd as consisting of over 300 animals [2]. These goats are specifically used to target hard-to-reach areas where traditional mowing equipment cannot operate effectively [1], [2].
Dense brush and overgrown weeds can create significant hazards for aviation operations. By grazing the land, the goats remove the vegetation that otherwise serves as cover for animals, such as deer or coyotes, that could wander onto the tarmac [1]. This reduces the likelihood of bird strikes or animal-related collisions during takeoff and landing [2].
Beyond wildlife management, the initiative serves as a wildfire mitigation strategy. In the arid climate of Colorado, overgrown brush acts as tinder that can carry fire quickly across a landscape [1]. The goats consume this biomass, creating a natural firebreak around the airport's infrastructure [2].
Using livestock for vegetation control is an increasingly common practice for government and municipal entities. It provides a low-emission alternative to gas-powered machinery and avoids the use of chemical herbicides on the soil [1]. The animals move through uneven terrain and steep embankments that would be inaccessible or dangerous for human crews [2].
The operation allows the airport to maintain safety standards while reducing its reliance on heavy machinery in sensitive areas [1].
“The airport has deployed 322 goats to handle the task.”
The use of targeted grazing at Centennial Airport reflects a broader shift toward 'green infrastructure' in aviation safety. By replacing mechanical mowing and chemical spraying with biological controls, the airport reduces its carbon footprint and chemical runoff while addressing the dual threats of wildfire and wildlife incursions, which are persistent challenges for airports located in wildland-urban interfaces.
