Dirty Dozen reports – 2010

Local authorities are among the most important bodies for instigating action for the tracking, control and eradication of invasive species.  The Data Centre has engaged with local authorities staff to explore how best it can provide a useful service to support their work.  What data was most useful to local authorities (and in what format) was the subject of detailed discussions between the Data Centre and the heritage officer network at a seminar in June 2010.

At this meeting, there was unanimous agreement that the provision of detailed information on key invasive species is an important service that should be provided by the Data Centre to support the work of local authorities.  As a start in this process, the Data Centre has provided tailored reports to 34 local authorities with detailed information on the most significant invasive species within their jurisdiction.  Each report was titled Report on the Dirty Dozen Non-native Invasive Species – [local authority or county name].

The use of the term ‘Dirty Dozen’ refers to the 12 species profiled in the report for that area. The 12 species chosen for each report were based on their presence in the area and their potential for impact and spread.  The criteria for listing the species are detailed in each report.  For those areas that did not have 12 high-impact invasive species reported from their area, then invasive species in nearby areas were profiled as potential invaders. Each report contains:

• A profile of the top twelve ‘dirty dozen’ most important invasive species within their area
• Distribution maps of the locations where they are known to occur within the county/ local authority region
• A ‘Useful Resources and Reference’ section in relation to invasive species;
• Relevant policy and legislation information

Records for these invasive species was also supplied to each local authority in GIS format.

There are 34 county and city councils in the Republic of Ireland. For those counties with more than one local authority within it the reports were compiled and sent to both the City and County Councils in that county.

Each of the reports are quite large (most >15MB)  and may take some time to download
