Rubber vine (Cryptostegia grandiflora) is an invasive weed that is choking out many woodlands and riverside areas throughout northern Queensland. Not only does it create dense thickets, removing pastoral country from production, it is a refuge for feral pigs and removes ground cover promoting erosion along creeks and rivers. Rubber vine is relatively fire sensitive provided the stem base of each plant is heated. Burning in the late dry season will yield high intensity fires that may kill most juvenile plants and 50–70% of adult plants. Fires of this intensity need
3–4 t/ha of grass fuel.
