Land Cover Dynamics & Phenology

Theme Overview

Land cover dynamics and phenology datasets characterise the changes in vegetation cover due to seasonal (phenological) or long term (climatic) influences.

Agricultural and man-made influences such as land-clearing can also be seen in the data.

The fractional vegetation cover and persistent green vegetation products show the changes in time and space of the green (photosynthetically active) vegetation component relative to the brown, dry or dead (non-photosynthetically active) vegetation and bare soil components.

The phenology and dynamic land cover products provide metrics for seasonal growth cycles in terms of the start, end and duration of each growth event.

TERN AusCover’s land cover dynamics and phenology products provide baseline information for past and current vegetation conditions at the national scale.

Seasonal ground cover - Landsat, JRSRP algorithm
Estimates of ‘true’ ground cover for each season, restricted to areas of less than 60% woody vegetation, by combining information from the Persistent Green and Seasonal fractional cover products.

Seasonal fractional cover - Landsat, JRSRP algorithm
Representative seasonal medians of fractional cover, with landcover fractions representing the proportions of green, non-green and bare cover. The benefits of compositing seasonal images are the creation of a regular time-series capturing seasonal variability, and the minimisation of missing data and contamination present in single date imagery.

Fractional cover - Landsat, JRSRP algorithm
Vegetation fractional cover represents the exposed proportion of green, non-green, and bare cover within each pixel. Landsat-scale ground cover information is important for soil erosion and nutrient flux estimates into the stream network, as well as assessing the impact of human activities.
