Figure 25 Prevalence of threats to Australian threatened taxa
A series of column graphs. They are ordered by size, from the threat that affects most taxa (invasive species) to that which affects the fewest (pollution). In this order, the graphs show that: 1. more than three-quarters of taxa threatened by invasive sp

EPBC Act = Environment Protection and Biodiversity Conservation Act 1999

Notes:

  1. n = 1,533
  2. Each graph is scaled according to the number of taxa listed under the Environment Protection and Biodiversity Conservation Act 1999 as being affected by each threat category (e.g. Urban development). Each chart segment represents a subclass threat (e.g. Housing). The threat category ‘Geological events’ is not shown here because it impacts <20 species, and subclass threats that impact <5 taxa (e.g. Renewable energy) are not shown because they were too small to be displayed effectively.
  3. ‘Agriculture (other)’ includes land clearing, habitat fragmentation and/or habitat degradation.

Three line graphs. The first shows that median fire size has been falling since 2000, possibly helped by the introduction of savannah burning. The second shows that since the Savanna Burning Methodology was enacted, the number of fires in high rainfall re
