DEFINITION
Undisturbed Plant Community
- Definition: A plant community that has grown naturally without human aid and has been left undisturbed over a long period of time (virgin vegetation).
- Adaptation: It allows individual species to fully adjust themselves to the local climate and soil conditions.
- Contrast: It strictly differs from planted vegetation (orchards, agricultural crops, or gardens) which operate under human supervision.

DISTINCTION
Legal vs. Actual Canopy
- Forest Area: The area legally notified and recorded as forest land by the government in revenue records. Trees may or may not physically exist there.
- Forest Cover: The area actually occupied by forests with a tree canopy. This is mapped on the ground using satellite imagery (often requiring a canopy density of >10%).
- General Trend: Forest Area is generally greater than Forest Cover.
