ECOSTAT HYMO workshop – 12-13 June 2012
Questionnaire on biological methods• MS were asked to identify biological methods
to detect the effects of hymo pressures for the four water categories– Name of method
– Identify pressures to which the method responds
– Has the method been intercalibrated?
– Is the method included in the WISER methods overview?
• Additional information from intercalibration was considered for this presentation
• 9 MS provided information on biological methods:– Rivers – 7 MS (AT. BE/W, DE. IT, NL, NO, SI)
– Lakes – 5 MS (AT, DE, NL, NO, SI)
– Coastal waters – 2 MS (ES, NL)
– Transitional waters – 3 MS (IT, NL)
Questionnaire responses
– Focus on invertebrates and fish; both hydrology and morphology pressures; multimetric indices responding to multiple pressures
– Methods intercalibrated, but not specifically for hymo
– Invertebrates• mostly “general pressure” methods
• Only few methods specifically aimed at hymo (SI: SMEITH)
– Fish• Response to hymo and other pressures well documented
• Not specifically targeted at hymo (but see AT - FIA)
River methods
• Focus on fish, benthic fauna, phytoplankton– Fish fauna – AT, NL, NO
• IC: Validation only with expert judgement or other pressures
– Benthic fauna - DE, SI, NL• IC: All 3 methods validated for HM pressures (sign pressure-response
relationships with lake shore modification metrics and indices)
– Macrophytes - AT, NL, NO • AT, NL – validation and IC only for eutrophication
• NO – new method for HM pressures
– Phytoplankton/ Phytobenthos• NL – method validated/ IC only for eutrophciation
Lake methods
• Only 4 methods reported: Benthic fauna (2x), Macroalgae/Sea Grasses, Phytoplankton– Benthic fauna (ES, NL)
• IC: validation with multipressure index
– Sea Grasses (NL)• IC: response to hymo not specifically demonstrated
– Phytoplankton (ES)• Residence time
Coastal waters methods
• Benthic fauna (ES, IT, NL)– IC: validation with multipressure index
• Fish (ES, NL)– IC: no specific information on response to hymo
pressures (validation with multipressure index)
• Macroalgae / Sea Grasses (IT, NL)– IC: response to hymo pressure not specifically demonstrated
Transitional waters methods
ECOSTAT HYMO workshop – 12-13 June 2012
• Rivers – AT (Gisela Ofenboeck)
• Lakes – NO (Odd Terje Sandlund)
• Coastal/Transitional – ES (Angel Borja)
Presentations:
Questions for session B – Biological Methods• Are current biological assessment methods
appropriate to pick up hydromorphological alterations?
• Has response to hymo pressures been demonstrated? If not, why not?
• What features of method design make a biological method suitable or unsuitable for hymo pressures?
• What further method development is ongoing/needed?• Now (for next RBMP)• Longer term
