<speciesfyi-glossary slug="phytogeography"></speciesfyi-glossary>Definition
The branch of biogeography concerned with the geographic distribution of plant species and vegetation types.
Detailed Explanation
Plant distributions are constrained by climate (temperature, precipitation), soils, and dispersal barriers. The striking floristic similarity between eastern North America and East Asia — where many genera share species despite separation by the Pacific — reflects ancient connections through the Bering land bridge and shared Tertiary forests. Phytogeography informs invasive species risk assessments by identifying source regions with similar climates to potential invasion targets.
