Tree Ring Cross-Section Diagram - Understanding Annual Growth Patterns #273557 (License: Personal Use)

This vector illustration depicts a classic dendrochronological cross-section of a tree trunk, with clearly defined concentric growth rings indicating yearly development. The outer dark brown bark contrasts with lighter sapwood and heartwood layers, while radial cracks suggest natural drying or aging. Black lines mark key ring boundaries for educational clarity.

Used in educational content about forestry, climate science, or biology; ideal for articles on dendrochronology, sustainability, or nature studies where visual explanation of tree aging is needed.
