This layer shows the pixel-level history of forest loss: each pixel records the year in which its tree cover canopy was completely removed. It is derived from the Hansen/UMD Global Forest Change dataset (UMD/hansen/global_forest_change, band lossyear), produced from a Landsat time series at 30 m native resolution. Coloured pixels mark stand-replacement disturbance events, from the earliest years of the record up to the most recent year available; uncoloured areas had no detected loss.
The layer encodes, for every 30 m pixel, the year of tree cover loss defined as a stand-replacement disturbance (complete removal of the canopy). Values come from the lossyear band of the Hansen/UMD Global Forest Change collection on Google Earth Engine, where each pixel stores the loss year as an offset from 2000 (for example 23 = 2023); a value of 0 means no detected loss over the observation period.

For the requested polygon the TreeCoverLossReader (geo3bee, hansen_forest module) reads the lossyear band from the Global Forest Change asset (UMD/hansen/global_forest_change_2025_v1_13), clips it to the area of interest and returns a graduated raster where the pixel value is the year of loss. No loss is treated as background (masked).
