Siberian Larch Forest Stand Age Map from 1989-2012

Mapped estimates show the stand age of young Siberian larch forests from 1989 to 2012 at 30-meter resolution. The dataset was produced by ORNL_CLOUD using Landsat imagery, Global Forest Change data, and stand-replacing fire mapping. It models disturbances before 2000 and uses direct observations after 2000 to create a 24-year age distribution.

Use Cases

• Analyzing post-wildfire forest recovery rates using the modeled stand age layer.
• Studying carbon sequestration potential in young larch stands across Siberia.
• Calibrating forest growth models with spatially distributed age estimates.
• Mapping historical disturbance patterns in boreal forests from 1989-2012.
• Investigating relationships between spectral signatures from Landsat ETM+/TM and forest age.

Strengths

• Provides a 24-year continuous record (1989-2012) of forest stand age.
• Offers high spatial resolution at 30 meters for detailed landscape analysis.
• Method integrates direct observation (post-2000) and modeled data (pre-2000) from established sources like GFC and SRFM.

Limitations

• Conflicting last updated dates exist: one source states 2012-12-31, another states 2026-03-13.
• Specific column names, row counts, and file sizes are not provided by any source.
• Age estimates are limited to young forests less than 25 years old.
