Annual Woody Vegetation Cover For Western Australia Since 1988

State-wide vegetation cover datasets classify perennial woody vegetation from Landsat imagery at 30-meter resolution. Produced annually by Landgate, the data spans from 1988 to the present and distinguishes between forest and sparse woody vegetation categories based on cover density and height.

Use Cases

• Analyze long-term trends in forest cover density and sparse woody vegetation extent across Western Australia.
• Model vegetation structural changes using the 20% cover density and 2m height criteria for the forest category.
• Monitor annual shifts in the 5-20% vegetation cover class identified as sparse woody vegetation.

Strengths

• Annual time series provides consistent data from 1988 to the present.
• State-wide spatial coverage for Western Australia.
• Classification uses two distinct structural categories based on specific cover density and height thresholds.

Limitations

• Limited to two vegetation classes (forest and sparse woody), lacking finer species or health detail.
• Spatial resolution is 30 meters, which may miss smaller vegetation patches or detailed changes.
