Anemochory is the term used to describe the dispersal of plant seeds, spores, or fruits by wind. This method relies on wind currents to carry the propagules away from the parent plant.

– Anemochore refers specifically to dispersal by wind.
– Thalassochore refers to dispersal by seawater.
– Hydrochore refers to dispersal by water (generally, including fresh and salt water).
– Anemohydrochore refers to dispersal by both wind and water.

Wind dispersal is common among species that produce small, light propagules, or those with adaptations like wings or tufts of hair (e.g., dandelions, maple seeds) that aid in catching the wind. The effectiveness of anemochory depends on wind speed, propagule structure, and height of release.
