Blackberry is one of the most important weeds in Australia and is a major problem of pastures and native forests on the tablelands and coast in NSW. Blackberry is invasive and covers large areas so that few other plants can compete and Blackberry dominates. Reproduction is by seed, root suckers and layering at the stem tips. Birds distribute the seeds over a wide area. Control is by prevention, by maintaining a dense cover of useful plants to prevent seedlings establishing. Herbicide treatment is the most practical method of control but grazing by goats is effective and economical (compared to chemical control).
