Objective of ecostat mandate: Objective of ecostat mandate

Objective 3 of ECOSTAT mandate:

• Objective 3 of ECOSTAT mandate:

• “To compare approaches and promote exchange of experiences on development and application of monitoring and biological classification systems in the Member States”

• 2010-2012 Priority tasks on alien species:

• Determine how to use alien species (AS) data in classifying ecological status

• Evaluate the potential of existing alien species databases for compiling lists that can be used under the WFD

• Link to the Invasive Species Strategy and parallel activities (e.g. MSFD)

LEAFPACS – macrophyte classification tool in GB

• LEAFPACS – macrophyte classification tool in GB

• Outputs – range of metrics to reflect species composition, richness, abundance

• Combined to produce an EQR

7 high impact (HI) alien plant species listed by UK TAG (e.g. Crassula helmsii, Myrophyllum aquaticum)

• 7 high impact (HI) alien plant species listed by UK TAG (e.g. Crassula helmsii, Myrophyllum aquaticum)

Only one species – Azolla filiculoides – can have direct effect on WFD classification

• Only one species – Azolla filiculoides – can have direct effect on WFD classification

• 45 sites with HI species used in classification (2009)

• Little difference in classification in water bodies with and without HI species

Azolla filiculoides, Crassula helmsii + Myriophyllum aquaticum all scoring species

• Azolla filiculoides, Crassula helmsii + Myriophyllum aquaticum all scoring species

• Mixed results – HI species in lakes more likely to affect WFD class than for rivers

Study by Cambridge University on invasion by Dikerogammarus villosus (killer shrimp) in GB

• Study by Cambridge University on invasion by Dikerogammarus villosus (killer shrimp) in GB

• Potential effects on biomonitoring

• Effects of D. villosus on invertebrate classifications using RICT

• Preys on high-scoring species – e.g. mayflies, blackflies, gammarids

• Leads to reduction in ASPT scores in high and good rivers, inflation in scores in lower quality rivers

“The potential effectiveness of current WFD monitoring strategies could be improved to include a measurement of bio-contamination within biological communities. These methods are being developed and their implementation in ecological monitoring being discussed. Generally evidence of bio-contamination (the presence of non-native species) within invertebrate communities reduces the resultant overall ecological status of the water body under assessment. Incorporating these methods may provide a more accurate assessment of ecological status”

• Country-level databases

• Austria, Belarus, Belgium, Denmark, Estonia, Germany, Greece, Iceland, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Republic of Ireland, Russia, Spain, Sweden, Switzerland, United Kingdom

Various definitions of alien species (e.g. different cut-off dates)

• Various definitions of alien species (e.g. different cut-off dates)

• Complementarity and gaps in existing online information systems

• Different scope (geographical, taxonomic, etc.)
• Lack of geo-referenced records

• Variability in the quality of information (across countries, regions, environments)

• Incompatibility among databases (e.g. nomenclature issues)

• Not always regularly updated

Aims:

• Aims:

• to increase harmonization of IAS data from distributed sources in support of the EU 2020 Biodiversity Strategy

• to identify strategies for long-term maintenance of IAS data

• to develop standard indicators for pathways and impacts, and standard protocols for risk assessments and data requirements (for pathways and impacts)

• To collaborate with EASIN

Terms and definitions (in the EC Directive?)

• Terms and definitions (in the EC Directive?)

• Creating WFD-specific lists of alien species

• How to monitor and record alien species

• Risk assessment

• Assigning levels of impact to individual species

• An outlet for publication (e.g. CEN? Other options?)

EASIN and COST (if funded) will deal with the data harmonisation issues

• EASIN and COST (if funded) will deal with the data harmonisation issues

• ► still need to ensure that data on relevant WFD species are readily available

• WFD classification tools are not performing well enough to detect all the problems from alien species

• ► this means either improving those tools or having an extra step in classification, as in the UK – or both

•  

• Need guidance at a European level on some of the alien species issues specific to the WFD

• ► guidance on using data, and consistent rules for how to categorise the impact of alien species, are still needed to help with WFD assessments
