Abstract
Consistent with the Pastoral Lands Board’s (PLB) direction, data and analyses are reported at the Land Conservation District (LCD) scale. Some caution is urged when interpreting the report as this summary data may mask the variation in condition evident on leases within an LCD.
In the Kimberley, the analyses of the WARMS point data suggest that the trend in rangeland condition indicated by the frequency of desirable perennial grasses is stable. This is consistent with previous recent reports. However, the analyses of MODIS satellite plant cover data and greenness response indicated by NDVI, suggest areas of the Derby – West Kimberley and Halls Creek - East Kimberley LCDs where condition of land under pastoral lease is at risk.
In Pilbara, the WARMS point data suggest that the recent trends in condition indicated by the frequency of desirable perennial grasses, are variable while there has been an overall downward trend measured since 1994. The MODIS cover and NDVI analyses point to parts of the Ashburton and Roebourne - Port Hedland LCDs where condition of land under pastoral lease is at risk.
