Perennial Woody Vegetation Cover Time Series for Western Australia

State-wide vegetation cover datasets classify perennial woody vegetation from Landsat imagery at 30-meter resolution. Produced annually by Landgate, the data series extends from 1988 to the present. The classification includes two categories: forest meeting structural requirements and sparse woody vegetation.

Use Cases

• Analyze long-term trends in forest cover density and sparse woody vegetation categories across Western Australia.
• Model changes in vegetation structural requirements for 20% cover density and 2m height at maturity over the 1988-present time series.
• Integrate the 30m ground pixel Landsat imagery with other spatial datasets for land cover change detection.
• Assess annual variations in the two vegetation classes to monitor land management and conservation outcomes.

Strengths

• Provides annual data from 1988 to the present, offering a multi-decade time series.
• Based on Landsat satellite imagery with consistent 30-meter ground pixel resolution.
• Classification includes two specific structural categories for woody perennial vegetation.

Limitations

• Limited to two broad vegetation classes, lacking finer species or health detail.
• Spatial resolution of 30 meters may not capture small-scale vegetation patches or changes.
• Relies on satellite imagery interpretation, which can be affected by cloud cover and atmospheric conditions.
