Present Distribution of Slender thistle (Carduus pycnocephalus/tenuiflorus) in Victoria (Nox)

Map:  Present distribution Slender Thistle
Present Distribution of Slender thistle
The infestations shown on these maps are derived from the Integrated Pest Management System (IPMS) (2003), Flora Information Systems (FIS) (2002) and Noxious Weed Survey (Lane et al 1980).

The map is not meant to display a complete statewide inventory for this species. There are areas, for instance, where this species may be present but has not been recorded. IPMS data (managed by DEPI), for example, reflects the regional policies, priorities, programs and available human resources etc over the last 12 or so years (up to early 2003). It is reasonable, therefore, to assume that for most species, the extent of infestations in a region will be greater than is recorded.
