GAVIA - Global Avian Invasions Atlas Project:
The human-mediated introduction of animals into new areas is a key driver of species extinctions and global environmental change, and a major drain on economic resources. Preventing new invasions is the best way to minimize their impact, but this requires understanding the factors influencing whether or not species establish and spread in foreign environments.
To this end, Professor Tim Blackburn and I have created a novel, spatially referenced, global data set on the distributions of alien birds. The GAVIA database currently comprises over 27,000 distribution records for over 900 alien bird species, based on over 700 published references and substantial unpublished information derived from consultation with over 600 organisations and experts worldwide. This represents the most comprehensive resource on the global distribution of alien species in any major taxon.
Substantial progress in invasion biology has come from studying birds, where detailed historical and ecological information allows determinants of invasion success or failure to be explored. Nevertheless, significant gaps in understanding remain. Most notably, although the necessary stages through which a species passes to become invasive are relatively well documented (transport, release, establishment, spread), aside from a few case studies, the processes of invasive spread have largely been ignored for birds. Understanding these processes is critical in order to mitigate the impacts of alien species, especially given the need to determine the likely effects of global change on the potential for species to invade new regions.
The primary reason for the lack of studies on invasive bird spread has been the absence of high-quality, spatially and temporally explicit data on the distributions of alien birds. The creation of the GAVIA Project has rectified this data gap, and my PhD project exploits the GAVIA database in order to address significant unanswered questions on the determinants of alien species richness and spread.
