Reports

NSW Report on Native Vegetation 2011-13 (PDF, 1.6MB) is the fourth report to be released and combines four major reports relating to native vegetation management in NSW. These are the:

  • Native Vegetation Report Card
  • Private Native Forest Report
  • NSW Woody Vegetation Change Report 2010–2011
  • Compliance and Enforcement Report Card.

The Native Vegetation Report Card provides the latest information on the conservation, restoration, management and approvals for clearing native vegetation across NSW.

Over 300,000 hectares of native vegetation were conserved or improved across the state in 2012-13. In contrast, only 2140 hectares were approved to be legally cleared where environmental values were maintained or improved through mechanisms such as the use of offsets.

The Private Native Forest Report discusses land managed under Private Native Forest (PNF) Property Vegetation Plans (PVPs). Around 61,000 hectares of land were approved during 2012-13 to be managed under PNF PVPs.

The NSW Woody Vegetation Change Report 2010–11 covers losses in woody vegetation due to clearing for agriculture, forestry and infrastructure activities. It also reports losses in woody vegetation resulting from bushfires.

The report does not identify gains in woody vegetation due to planting and natural regrowth. The total net reduction in the area of woody vegetation in NSW over the period 2010-11 was 29,900 hectares or 0.04% of the area of NSW.

OEH is responsible for implementing a credible compliance and enforcement framework to protect the environmental values of native vegetation and ensure that landholders who comply with the law are not disadvantaged.

OEH undertakes this role through stakeholder engagement, strategic investigations, appropriate enforcement actions and targeted compliance campaigns. The Compliance and Enforcement Report Card provides Information on OEH’s compliance and enforcement activities.

Report 2011-13 demonstrates that extensive areas of native vegetation are being actively managed and conserved by farmers and rural landholders who understand the value in conserving remnant vegetation.

Woody vegetation change

The report is being released with accompanying data on woody vegetation change, including Spot 5 (Spot5WoodyChangeNSW2009-2011.xls, 126KB) and Landsat (SlatsLandsat1988-2011.xls, 241KB) data. These provide woody change data for the years 1988-90 to 2010-11 at the local government (LGA), local land service (LLS), catchment management authority (CMA) and interim biogeographic regionalisation of Australia (IBRA) region level. The statistics show annualised rates of change in hectares per year, from 1988-90 to 2010-11, and are available as Excel spreadsheets.

This data enables stakeholders to access information that is used for calculating annual reporting of woody vegetation change.

These figures are derived from the analysis of Landsat satellite woody change data (25m) for 1988-90 to 2009-10 and Spot 5 (5m) data 2009-10 to 2010-11. More information on access to these and other spatial data products can be found on the Ancillary Vegetation Products: Data Inventory page.

Woody vegetation change measurements from Landsat and SPOT 5 imagery are not directly comparable due to the different resolution of the sensors. When analysing trends in woody vegetation change SPOT 5 and Landsat measurements should not be directly compared. The report A Comparison of Woody change Mapping based on SPOT 5 and Landsat TM Imagery using 2010-2011 Imagery (PDF, 1.3MB) provides further information. 

Limitations to woody vegetation change data

Woody vegetation change data is derived from analysis of satellite images using the SLATS Methodology and used to report against a number of national and statewide programs. The information provided allows users the opportunity to access the raw data that supports the figures included in the various reports on native vegetation.

In accessing and analysing the information provided, it is important to realise the following:

  • Woody vegetation changes do not take into account regrowth or replantings.
  • The figures do not distinguish between approved, permitted, exempt or illegal clearing under the Native Vegetation Act 2003.
  • Since clearing authorised in one year may not happen in that year, clearing rates and PVP approvals data cannot be aligned.

Woody vegetation extent

Woody vegetation extent differs slightly as a measure of vegetation from woody vegetation change. Woody vegetation extent measures Foliage Projective Cover (FPC) which is used across many Australian vegetation classification frameworks. For the purpose of this data, FPC refers to the vertically projected percentage cover of photosynthetic foliage from tree and shrub life forms only.

The distribution of woody FPC by catchment management authority and IBRA region are published in the spreadsheets below. The counts of woody vegetation for each FPC value were derived from the Landsat woody extent and FPC v2.1 2008 product. The cell value in the spreadsheets is FPC plus 100 e.g. 110 represents an FPC of 10.  The cell size is 25m x 25m. These data were not included in the Annual Report, but are reported here as part of the Natural Resource Commission's auditing of the state's commitments to natural resource management embedded in the State Plan.

More information on this and other spatial data products can be found on the Ancillary Vegetation Products: Data Inventory page.

The woody vegetation extent data and FPC 2008 product is published below for each IBRA and CMA region in NSW as Excel spreadsheets. It is not included in the Annual Report, but is reported here as part of the Natural Resource Commission’s auditing of the state’s commitments to natural resource management embedded in the State Plan.
