Flight characteristics were determined for samaras of seven maple species and evaluated in terms of their contribution to dispersal potential. Two components of samara flight were identified, an initial fall distance prior to entering autorotation, and the terminal velocity once in autorotation. Despite considerable interspecific variation in samara dimensions, terminal velocities are quite similar for all species and exhibit good fit to a general model relating flight characteristics to samara dimensions for maple samaras. Even assuming relatively light wind conditions, substantial samara dispersal distance can be achieved by understory species even with release from low heights. Forest Sci. 30:434-440.
