Raunkiääriien
Raunkiääriien, also known as Raunkiær plant life-forms, are a system for classifying plants based on their perennating (surviving) buds or shoots. Developed by Danish botanist Christen Raunkiær in the early 20th century, this classification aims to relate plant form to climate. The system categorizes plants into major groups, or life-forms, based on the position of their perennating organs relative to the ground and their protection during unfavorable seasons.
The primary life-forms include phanerophytes (trees and shrubs with buds well above the ground), chamaephytes (shrubs
The Raunkiær system provides a valuable tool for ecological studies, allowing scientists to compare vegetation across
