Native to the Caribbean and tropical South America, redwood is a bushy shrub. Originally imported and planted in northern Queensland as a cattle feed, redwood escaped cultivation and invaded surrounding land. It forms dense thickets that replace native vegetation.
You must take reasonable action to minimise the risk of spreading Redwood to ensure the situation isn't worsened.
You must report all sightings to Biosecurity Queensland within 24 hours.
