The need for a more open attitude towards invasive alien species data

New research published with the support of the FP7 large-scale bioinformatics project Building the European Biodiversity Observation Network (EU BON) and the Alien Challenge COST action reveals the importance of open data in the study and control of invasive alien species. The study was published online in open access in the journal Management of Biological Invasions.

Invasive alien species cause a wide variety of problems, including issues related to conservation; to human and animal health; to agriculture and to fisheries management. But how can science be useful to manage such potential issues?

"To advise policy makers and inform land managers on the dangers posed by and how to fight alien species we need to understand the invasion process. Ideally, we would like to be able to predict the causes, routes and progression of invasions." explains Dr. Quentin Groom, Botanic Garden Meise, Belgium.

Recently, several research groups have pioneered the process of "Horizon Scanning" for new alien species, also there have been parallel developments in the creation of dynamic ecological models to predict invasions. However, the greatest limitation to these advances is the lack of suitable data.

"The problem of invasive species is international and rapidly changing. Data are required from an extensive area, for many species and for a long period but what is currently available is patchy and often inaccessible. We argue for the importance of open data to tackle the problem of invasive alien species." explains Dr. Groom.

This new research reviews why access to data are so important to invasive alien species research and gives an overview of the reasons why data are unavailable to researchers. Currently access to data is patchy and is restricted in many ways:

• Legally, the use of restrictive data licensing blocks its use.
• Technically, many software systems don't adequately support sharing, particularly in their provision of unique identifiers.
• Culturally, data secrecy is the default position for most organizations.

Gradually, data are becoming more accessible and attitudes towards data access are changing. The advent of data publications allows researchers to attract citations from their data, while simultaneously making their data accessible and discoverable.

The community of biodiversity observers is highly fragmented and the creation of a European biodiversity network will improve communication so that grassroots biodiversity surveyors will understand issues of data sharing, citation and licensing that are so critical for a rapid response to invasive species.
