Blackberry in Tasmania

  • Blackberries occur in all settled areas of Tasmania (see map). Blackberries prefer open situations and occur as a weed in disturbed bush, along stream-sides, roadsides, tracks and fence lines, and in degraded pasture and neglected areas.
  • Severe infestations of blackberry on farmland can effect agricultural production and reduce access to water and land. Blackberry is also an important weed of disturbed and degraded native vegetation, particularly along stream-sides. Blackberries can also pose a significant fire hazard and provide a haven for vermin.
