Abstract
Photo Gallery Little is known about the relative importance of mechanistic drivers of plant spread, particularly when long-distance dispersal events occur. We integrated wind dispersal mechanisms into an analytical population spread model. We used high-resolution data collected on a New Zealand mountain to parameterize and validate the model, focusing on an invasive population of Corsican pines (Pinus nigra). Two variables rarely taken into account in models of spreading, seed falling velocity (i.e., how fast a seed falls in still air) and wind turbulence, greatly impacted movement. This study offers interesting possibilities for population biology modeling and management of invasive plants.
