Phytogeography (Plant Geography)

Phytogeography, also known as plant geography, is the branch of biogeography that studies the distribution of plant species across different regions of the Earth and the factors influencing their spread. It examines how climate, soil, altitude, and geological history affect plant life and ecosystems.

Branches of Phytogeography:

1. Descriptive Phytogeography – Maps and classifies plant distribution patterns.
2. Ecological Phytogeography – Studies how environmental factors (climate, soil, water) influence plant distribution.
3. Historical Phytogeography – Investigates how past climatic changes, continental drift, and evolution have shaped plant distribution.
4. Floristic Phytogeography – Focuses on plant species diversity and classification in specific regions.

Phytogeography is essential for conservation biology, agriculture, forestry, and understanding climate change impacts on vegetation.
