Imperata cylindrica (Non-native)

Cogon grass exudes substances into the soil that suppress other plants ability to grow, allowing it to form dense colonies wherever it establishes. Large infestations of this plant can alter the fire regime by causing more frequent and intense fires, injuring or destroying some native plants and potentially damaging property. It can displace native plants used by native animals, and has been known to displace some ground-nesting animals due to the dense ground cover it creates.
