Present Distribution of African boxthorn (Lycium ferocissimum) in Victoria (Nox)
 Present distribution of African boxthorn | The infestations shown on this map are derived from the Integrated Pest Management System (IPMS) database which is managed by DSE. Mapping and monitoring of weeds is undertaken on a continuous basis but is far from complete in many areas, and not all data has been entered into the database. Therefore the maps are not meant to display a complete statewide inventory for this species. Rather, the data reflects the regional policies, priorities, programs and available human resources etc over the last 12 or so years (up to early 2003). There are areas where this species may be present but has not been recorded due to these constraints. It is reasonable, therefore, to assume that for most species, the extent of infestations in a region will be greater than is recorded. | ||
