Key finding

A large proportion of pre-clear threatened flora habitat remained in Queensland in 2013. However, the proportion varies greatly among bioregions and among flora groups. The greatest losses have occurred in the New England Tableland, South East Queensland, Brigalow Belt and Mulga Lands bioregions.

Queensland

Pre-clearing habitat extent for 701 currently threatened flora species was modelled for Queensland. Prior to land clearing, habitat was widespread in Queensland for:

  • 195 threatened eucalypt forest and woodland species
  • 333 threatened rainforest and scrub species
  • 25 threatened Acacia forest, woodland and shrubland species
  • 52 threatened wetland and Melaleuca open woodland species
  • 16 threatened grassland and forbland species
  • 80 threatened heath and other coastal community species.

The largest extent of pre-clearing habitat for all threatened flora groups was found in the Brigalow Belt.

Large extents of pre-clearing habitat were also found in the South East Queensland, Cape York and Einasleigh Uplands bioregions for all flora groups, with the exception of threatened Acacia forest, woodland and shrubland, for which pre-clearing habitat was most extensive in the Mitchell Grass Downs and Mulga Lands bioregions.

Habitat for threatened flora sustained ongoing loss between 1997 and 2013, the loss slowing after 2005-2007.

  • Between 57% and 70% of the pre-clearing habitat for most threatened flora remains uncleared.
  • Threatened grassland and forbland flora is the exception—66% of habitat was cleared by 2013.

Land clearing in Queensland between 1997 and 2013 was primarily for pasture development.

It should be noted that some threatened flora species may be able to utilise non-remnant vegetation and that threatening processes such as habitat degradation, loss of habitat connectivity, disease, herbivory, invasive species, grazing and inappropriate fire management place significant additional pressure on threatened flora in both remnant and non-remnant habitat, but are not considered here.

Brigalow Belt

Pre-clearing habitat extent for 190 currently threatened flora species was modelled for the Brigalow Belt (BRB) bioregion. Prior to land clearing, BRB provided habitat for:

  • 105 threatened eucalypt forest and woodland species
  • 36 threatened rainforest and scrub species
  • 13 threatened Acacia forest, woodland and shrubland species
  • 10 threatened wetland and Melaleuca open woodland species
  • 10 threatened grassland and forbland species
  • 16 threatened heath and other coastal community species.

The trend in flora habitat extent between 1997 and 2013 in BRB is one of ongoing loss of habitat for all flora groups, with a slowing of loss for all flora groups after 2005-2007.

  • Only 20% of pre-clearing threatened Acacia forest, woodland and shrubland flora habitat remained uncleared in 2013.
  • 30% of the pre-clearing habitat for threatened grassland and forbland flora remained.
  • 34% of pre-clearing habitat for threatened rainforest and scrub flora was intact.
  • Slightly more than 50% of the pre-clearing habitat for threatened eucalypt forest and woodland species was retained.
  • 71% of pre-clearing habitat for threatened heath and other coastal community flora remained uncleared.

BRB land clearing between 1997 and 2013 was primarily for pasture development.

It should be noted that some threatened flora species may be able to utilise non-remnant vegetation and that threatening processes such as habitat degradation, loss of habitat connectivity, disease, herbivory, invasive species, grazing and inappropriate fire management place significant additional pressure on threatened flora in both remnant and non-remnant habitat, but are not considered here.

Cape York Peninsula

Pre-clearing habitat extent for 135 currently threatened flora species was modelled for the Cape York Peninsular (CYP) bioregion. Prior to land clearing, CYP provided habitat for:

  • 20 threatened eucalypt forest and woodland species
  • 92 threatened rainforest and scrub species
  • 16 threatened wetland and Melaleuca open woodland species
  • 1 threatened grassland and forbland species
  • 6 threatened heath and other coastal community species.

The trend in flora habitat extent between 1997 and 2013 in CYP is one of ongoing loss of habitat for all flora groups, except for threatened grassland and forbland flora and threatened heath and other coastal community flora, which have remained uncleared since 1997.

  • More than 98% of pre-clearing habitat for threatened eucalypt forest and woodland flora, threatened rainforest and scrub flora and threatened wetland and Melaleuca open woodland flora remained uncleared in 2013.
  • Most (92%) of the pre-clearing habitat for threatened heath and other coastal community flora remained as remnant vegetation.
  • 17% of pre-clearing habitat for threatened grassland and forbland flora had been cleared.
  • Habitat loss for threatened eucalypt forest and woodland flora and wetland and Melaleuca open woodland flora had slowed since 2009.
  • Clearing of threatened rainforest and scrub flora habitat increased between 2011 and 2013.

CYP land clearing between 1997 and 2013 was primarily for pasture development and mining.

It should be noted that some threatened flora species may be able to utilise non-remnant vegetation and that threatening processes such as habitat degradation, loss of habitat connectivity, disease, herbivory, invasive species, grazing and inappropriate fire management place significant additional pressure on threatened flora in both remnant and non-remnant habitat, but are not considered here.

Central Queensland Coast

Pre-clearing habitat extent for 57 currently threatened flora species was modelled for Central Queensland Coast (CQC) bioregion. Prior to land clearing, CQC provided habitat for:

The trend in flora habitat extent between 1997 and 2013 in CQC is one of ongoing loss of habitat for all flora groups, except threatened Acacia forest, woodland and shrubland flora which has remained largely uncleared since 1997.

  • One-third of the pre-clearing habitat for threatened grassland and forbland flora had been cleared by 2013.
  • About one-quarter of habitat for both threatened Acacia forest, woodland and shrubland flora and threatened wetland and Melaleuca open woodland flora had been cleared by 2013.
  • At least 85% of the pre-clearing extent of habitat for other threatened flora groups remained uncleared.
  • Habitat loss for threatened eucalypt forest and woodland flora and threatened rainforest and scrub flora has slowed since 2007.
  • Habitat for threatened heath and other coastal community flora has remained uncleared since 2006.
  • Habitat for threatened wetland and Melaleuca open woodland flora as well as grasslands and forblands has remained largely uncleared since 2009.

CQC land clearing between 1997 and 2013 was primarily for pasture development.

It should be noted that some threatened flora species may be able to utilise non-remnant vegetation and that threatening processes such as habitat degradation, loss of habitat connectivity, disease, herbivory, invasive species, grazing and inappropriate fire management place significant additional pressure on threatened flora in both remnant and non-remnant habitat, but are not considered here.

  • 1 threatened eucalypt forest and woodland species
  • 7 threatened Acacia forest, woodland and shrubland species
  • 2 threatened grassland and forbland species.

Habitat for threatened eucalypt forest and woodland flora and threatened grassland and forbland flora has remained uncleared since 1997 with small losses of habitat for Acacia forest, woodland and shrubland flora in 2003 and 2009.

  • Less than 1% of habitat for threatened eucalypt forest and woodland flora, threatened Acacia forest, woodland and shrubland flora and threatened grassland and forbland flora had been cleared in CHC by 2013.

CHC land clearing between 1997 and 2013 was primarily for pasture development.

It should be noted that some threatened flora species may be able to utilise non-remnant vegetation and that threatening processes such as habitat degradation, loss of habitat connectivity, disease, herbivory, invasive species, grazing and inappropriate fire management place significant additional pressure on threatened flora in both remnant and non-remnant habitat, but are not considered here.

The trend in flora habitat extent between 1997 and 2013 in DEU is one of slowing habitat loss for threatened eucalypt forests and woodland flora and threatened Acacia forest, woodland and shrubland flora since 2006.

  • About one-third of threatened rainforest and scrub flora habitat had been cleared by 2013.
  • Between 83–100% of pre-clearing habitat for most other threatened flora groups remained uncleared.
  • Habitat loss for threatened rainforest and scrub flora and threatened wetland and Melaleuca open woodland slowed from 2001 and 2003 respectively, then remained uncleared between 2011 and 2013.
  • Habitat for threatened heath and other coastal community flora has remained uncleared since 1997.
  • Habitat for threatened grassland and forbland flora has remained uncleared since 2001.

  • The loss of threatened wetland and Melaleuca open woodland flora habitat slowed from 2007.

WET land clearing between 1997 and 2013 was primarily for pasture development, forestry and cropping.

It should be noted that some threatened flora species may be able to utilise non-remnant vegetation and that threatening processes such as habitat degradation, loss of habitat connectivity, disease, herbivory, invasive species, grazing and inappropriate fire management place significant additional pressure on threatened flora in both remnant and non-remnant habitat, but are not considered here.

Indicator: Proportion of pre-clear threatened flora habitat that is remnant vegetation

Hectares of threatened terrestrial flora habitat predicted to have occurred across Queensland and per bioregion prior to land clearing and remaining as remnant vegetation between 1997 and 2013. Potential habitat has been created using both MAXENT which uses species presence records combined with 7 environmental layers (annual mean temperature, temperature seasonality, annual precipitation, mean moisture index of the lowest quarter moisture index, pre-clearing broad vegetation group, land zone and topographic ruggedness) and buffered species records. Habitat is refined using the latest Regional Ecosystems mapping (version 9, 2013).
