Vegetation Trend Classification For Southwest Agricultural Zone 1990-2022

A five-class summary of linear vegetation cover trends from 1990 to 2022 for the southwest agricultural zone of Western Australia. The dataset, created by Landgate, categorizes pixel-level trends into classes from major increase to major decrease based on a numeric trend index.

Use Cases

• Map spatial patterns of 'major increase' or 'major decreasing trend' classes to identify areas of significant vegetation change.
• Analyze the distribution of the 'no major change' class relative to 'increasing' and 'decreasing' trend classes for land management assessment.
• Use the pixel-based trend classes as a simplified input for regional environmental change models.

Strengths

• Provides a 33-year temporal coverage from 1990 to 2022.
• Offers a simplified, interpretable five-class categorization of vegetation trends.
• Focuses on a defined geographic region, the southwest agricultural zone.

Limitations

• Classes are derived from a numeric index without ground-truth ecological interpretation, limiting biological certainty.
• Spatial resolution and total pixel count are unspecified, affecting analytical granularity.
• Coverage is restricted to a single agricultural zone, not representative of broader regions.
