The Queensland and New South Wales (NSW) Governments regularly report the extent of clearing
of woody vegetation based on analysis of Landsat TM/ETM+ imagery1. This brief report presents
clearing data for sub-regions of rangeland bioregions in both jurisdictions up to 2010 and, in doing
so, updates and provides greater detail on information presented (to 2005) in Rangelands 2008 –
Taking the pulse (Bastin et al. 2008) (see pages 90-93).
Key points
The Statewide Landcover and Trees Study (SLATS) allows reporting of clearing extent in
Queensland’s rangelands between 1988 and 2010. NSW uses the SLATS method to report change
in woody cover for its rangelands. Widespread clearing increases agricultural production but is a
threat to biodiversity.

Clearing was a significant cause of change in extent of woody vegetation in Queensland
between 1988 and 2010. 56,302 km2 (4.1%) of Queensland’s rangelands were cleared
during this period.

Sub-regions of the Mulga Lands, Brigalow Belts North and South, and Desert Uplands
bioregions (IBRA2) in Queensland were most extensively cleared (between 23% and 43% of
area of the sub-IBRA).

Clearing was generally more extensive prior to 2000 except in much of the Mulga Lands
bioregion where the majority of clearing occurred in the first decade of this century.

Clearing was comparatively less extensive in the NSW rangelands: 2,775 km2 were cleared
between 1988 and 2010. More than half of this clearing occurred in the Cobar Peneplain
bioregion (1,540 km2). The area cleared in the NSW rangelands (reported in two-year
blocks) has been broadly similar throughout the 22-year period.

completely or partly within the rangelands are split into sub-regions (equal sub-IBRA).

Method
The Queensland Statewide Landcover and Trees Study (SLATS,
www.qld.gov.au/environment/land/vegetation/mapping/slats/; accessed 23 July 2012) produces a
time-integrated clearing history for all of Queensland that specifies when a Landsat TM pixel was
first cleared (starting in 1988) and, if so, when it may have been subsequently recleared (methods
described in Danaher et al. 2010). This image was intersected with a map of Queensland subIBRAs (version 6.1) to determine the extent of clearing and reclearing in each rangeland sub-IBRA
between 1988 and 2010, and major periods of clearing activity.
The NSW Government uses the SLATS method to generate a similar history of woody vegetation
change. Their statistics include reductions in the extent of woody cover due to clearing for
agricultural, forestry or infrastructure purposes plus fire. Change due to fire is not reported here.
Extent and time of clearing
Queensland
A total area of 56,302 km2 was cleared in the Queensland rangelands between 1988 and 2010 (Figs.
1 and 2). Area of clearing was largest in the Mulga Lands bioregion with 22,199 km2 cleared. The
proportion of bioregion area cleared was highest in the Brigalow Belts South and North (17.7% and
16.4% of area cleared respectively). Clearing was generally more extensive in the Queensland
rangelands prior to 2000 (36,566 km2 cleared) although it was a more recent phenomenon in much
of the Mulga Lands bioregion where 12,104 km2 was cleared in the first decade of this century,
contributing more than half of the total 22,199 km2 cleared in the rangelands during this period.
Clearing extent decreased substantially after 2006 (Fig. 3).
At the level of sub-regions, 42.7% (1,989 km2) of the Upper Belyando Floodout (BBN8) sub-IBRA
was cleared between 1988 and 2010 (mostly pre-2000, Table 1). Three Mulga Land sub-IBRAs
had >30% of their area (13,733 km2) cleared in the same period. A further ten sub-IBRAs in the
eastern rangelands had between 10% and 30% of their area cleared, comprising 24,153 km2.
Extent of clearing for all rangeland sub-IBRAs is tabulated in Appendix 1.
Some 3,418 km2 of the Queensland rangelands have been cleared twice since 1988, mainly in the
BBS12, ML2, ML1, BBN7, MGD8 and BBS1 sub-IBRAs (listed in decreasing order of area
recleared – area recleared ranged from 183 to 579 km2).
New South Wales
In the NSW rangelands, 2,775 km2 were cleared between 1988 and 2010 (Fig. 1) with 1,373 km2 of
this area treated between 1988 and 2000. Clearing was most extensive in the Cobar Peneplain: 825
km2 cleared prior to 2000 and 715 km2 treated subsequently, representing 2.1% of bioregion area
cleared between 1988 and 2010. Clearing of NSW rangeland sub-IBRAs has been relatively minor
compared with Queensland (Table 1 and Appendix 2). The Nymagee sub-IBRA of the Cobar
Peneplain (CP4) was most extensively cleared (724 km2). Proportional to sub-IBRA area, the
Moonie – Barwon Interfluve sub-IBRA (BBS20) had 6.5% of its area cleared.
Of the total area cleared, 47 km2 was cleared a second time, mainly in the Cobar Peneplain (35 km2
recleared). At sub-IBRA level, 20 km2 of the Nymagee (CP4) and 10 km2 of the South Olary Plain,
Murray Basin Sands (MDD1, Murray Darling Depression bioregion) were cleared a second time.

Year
The overall rate of clearing in NSW rangelands has changed relatively little over the period (Fig. 4).
Data from NSW Office of Environment and Heritage report clearing in two-yearly blocks; the mean
area cleared per two-year period was 252 km2, ranging from a little over 100 km2 cleared in 19921994 to approximately 400 km2 cleared in each of 1988-1990 and 2000-2002.

Clearing era
Discussion
Native vegetation in the rangelands has primarily been cleared to increase forage production for
livestock, although cropping also occurs closer to the rangeland boundary. In the Queensland
rangelands, extensive clearing is now largely a historical phenomenon. A lesser total area was
cleared in western NSW compared with the Queensland rangelands for the period reported (19888
2010). Whereas the annual area cleared in Queensland in recent years has declined, biennial
amounts of clearing in the NSW rangelands have fluctuated since 1988. Legislation governing
vegetation management applies in both Queensland and NSW (see
www.dnrm.qld.gov.au/land/vegetation-management, accessed 9 December 2013 and
www.environment.nsw.gov.au/vegetation/, accessed 22 October 2013).
Where the density of woody vegetation restricts pasture growth and limits pastoral production,
future alternative income streams might emerge through managing revegetation for conservation
and publicly recognised ecosystem services (Puig et al. 2011, Greiner et al. 2009), and the carbon
market (e.g. Bray and Golden 2009). Whatever the management outcomes, the SLATS program
provides spatially extensive and robust data for monitoring woody cover dynamics in both the
Queensland and NSW rangelands.
