To make sure at least some of the seeds land in a suitable growing place, the plant has to produce lots of seeds. Long-distance dispersal (LDD) of plant seeds by wind is affected by functional traits of the species, specifically seed terminal velocity and height of seed release above the vegetation cover (HAC), as well as by the meteorological parameters wind speed and vertical turbulence.
