Data on the Facilitation of Seed dispersal of Alien Plants During and After Road Construction

It includes the locations (XY coordinates) of 41 road construction sites along with an inventory of alien plant species, detailing traits such as life cycle stage, dispersal mechanisms, and the number of sites where alien plant species occurred.

From September to October 2019, a focused study was conducted on the dispersal of Ambrosia trifida seeds, at six patches along three completed roadwork sites. The seed dispersal experiment involved counting the number of seeds in an area using the quadrat method (0.25 x 0.25 m2); these results were converted to a 1 × 1 m2 area. The data can be used to highlight the need for management strategies to prevent the spread of alien plants during and after road construction.
