Figure 41 Extent of woody and nonwoody vegetation loss on rural regulated land by authorising Act, 2017–19
Bar graph showing that most of the loss of non-woody vegetation is unexplained and dies not fall under any act. Removal of woody vegetation more often falls under an act, but around half remains unexplained.

Note: Authorised clearing applies under the repealed Native Vegetation Act 2003 (NV Act), the Local Land Services Act 2013 (LLS Act) or other Acts (Plantation and Reafforestation Act 1999, Environmental Planning and Assessment Act 1979). Unexplained clearing refers to areas of vegetation loss on rural regulated land defined by the LLS Act for which the Department of Planning, Industry and Environment does not yet know the details.

Figure 45 Cumulative number of introduced species first detected anywhere in Australia, by year range
Figure 46 Cumulative number of introduced species first detected in Australia, by land-use zone and year range
Bar graphs showing that in the intensive land use zone, the total number of introduced species has climbed from 2030 in 1980 to 2405 at present and within these, invasive species has climbed from 100 to 126. In the extensive land use zone, the total numbe

Notes:

  1. The intensive land-use zone, extensive land-use zone and relatively natural zone are defined in Figure 6. These zones exclude the following bioregions: Coral Sea, Indian Tropical Islands, Pacific Subtropical Islands, Subantarctic Islands (i.e. that include Australian territories that are remote from the Australian mainland).
  2. The initial year range is 1901–80, followed by 5-year increments to 2020.

Figure 47 Cumulative number of plants and vertebrate animals introduced to Australia, by land-use zone and year range
Bar graphs showing that there are more introduced species in the intensive use zone in 2020 (2232) than in the extensive use (1345) or relatively natural (660). In remote territories in 2020 there were 778. In all cases, the numbers increase with time, an

Notes:

  1. The intensive land-use zone, extensive land-use zone and relatively natural zone are defined in Figure 6. An additional zone is shown for Australian territories that are remote from the Australian mainland, to include the following bioregions from IBRA7 in this analysis: Coral Sea, Indian Tropical Islands, Pacific Subtropical Islands, Subantarctic Islands.
  2. The initial year range is 1901–80, followed by 5-year increments to 2020.

Figure 48 Introduced species as a percentage of all species, by IBRA v7 bioregions
Map showing that introduced species are the highest percentage of all species (around 10%) in a large region that includes western Victoria, eastern South Australia and south-western New South Wales. The Kimberley also scores poorly.

Two maps showing that introduced species per bioregion is highest on the south east, from South Australia around to southern Queensland. Invasive non-native species are most common in the same areas.
