Response description
Drought and flooding both contribute to mineralisation and release of nutrients from organic matter. This can increase the build up of plant-available nutrients in the sediments, which are readily washed into water courses and wetlands in runoff.
Secondary effects
Eutrophication
Specification of relevant ecosystem type
All types of wetlands
Relevant ecoregion(s) according to Illies
All Nordic ecoregions
Suggested indicator
Frequency and severity of storms
Justification of indicator
Increase in eutrophication may result from large runoff events.
Suggested indicator 2
Height of water table
Justification of indicator 2
Desiccation may lead to oxidation and mineralisation of bound nutrients, which can then wash into water bodies and wetlands in runoff
