The seeds of dandelions are adapted to wind dispersal.

In the biology of dispersal, a dispersal vector is "an agent transporting seeds or other dispersal units".[1] Dispersal vectors may include biotic factors, such as animals, or abiotic factors, such as the wind or the ocean.[1]

Humans have been acting as dispersal vectors since we began moving around the planet, bringing non-native plants and animals with us. As trends in urbanization have increased, urban environments can act as staging grounds for species dispersal and invasion. Many non-native species exist in urban environments and the high rate of movement in an out of urban areas leads to a high level of dispersal to neighboring environments. [2]
