Modelling long-distance seed dispersal of Spathodea campanulata in the Society Islands

These datasets are related to the paper "Modelling long-distance seed dispersal of the invasive tree Spathodea campanulata in the Society Islands" published in Ecological Applications. We used a 3-D kinematic trajectory model (Computing Atmospheric Trajectory tool (CAT)) initiated from regional wind field data to assess the potential for long-distance seed dispersal (LDD) of a wind-dispersed invasive tree, Spathodea campanulata (African tulip tree) across the Society Islands (French Polynesia, South Pacific Ocean) following its initial planting and spread on the island of Tahiti. The main objective of our study was to determine whether S. campanulata can be expected to spread naturally among islands. Atmospheric dynamics, seed terminal velocity, precipitation, and temperature of air masses were considered to assess the potential for LDD between oceanic islands, with the island of Tahiti serving as the island source for multiple, geographically distant invasions. These datasets contain the number of simulated seed trajectories with Computing Atmospheric Trajectory tool (CAT) in the study area as well as all data corresponding to each figure found in the paper.
