International Tree-Ring Data Bank

The International Tree-Ring Data Bank is a global repository that collects and shares information about tree ring patterns from around the world. Tree rings are visible layers in a tree trunk that grow annually, providing clues about past climate conditions, environmental changes, and events like droughts or wildfires. Researchers use this data to study how ecosystems respond to climate change, improve our understanding of historical climate variability, and support conservation efforts. By making this information accessible, the data bank helps scientists and policymakers make informed decisions about environmental management and climate resilience.
