Invasive species, Driver of Environmental Change: eDrivers Project for the St. Lawrence System

The data used to characterize invasive species risk come from the global cumulative impacts assessment on habitats and are available on the NCEAS online data repository.

Cargo volume was used as a proxy of invasion risk under the assumption that risk of invasion is proportional to tonnes of goods transferred through ports. Cargo throughput in metric tonnes for the year 2011 was accessed through a variety of sources and cross-matched with entries in the World Port Index database (WPI).

It is possible to consult the scientific report of the eDrivers project: Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada and the additional data. It is possible to consult the application eDrivers.
