Brief description
The Extensive Land-use Zone (ELZ) describes the region of the State in which theland use is dominated by grazing and mining activities. Although the extent of native
vegetation remains largely intact, the structure and floristic
composition have been substantially altered since European settlement through
grazing by introduced animals such as sheep, cattle, goats and rabbits, and by
altered fire regimes. A total area of more than 236 million ha of native vegetation was mapped in Western
Australia - 93 per cent of the State. This comprised 228.4 million ha in the ELZ (99.9
per cent) and 7.7 million ha in the ILZ (30.3 per cent) (ref: http://www.agric.wa.gov.au/objtwr/imported_assets/content/lwe/vegt/tr249_part1.pdf)
