Habitat types key navigation

You can use the 'key navigation' function to identify a specific habitat by answering a set of questions. Starting from first question to next questions you select one of the possible answers. Here are samples of possible answers:
  • No ( 002 ) - Leading to question named '002'
  • Yes [ G ] - Leading to another questions subset of level G
  • No Factsheet icon[ E6 ] - Links directly to factsheet for E6

Question c01 :   Ice-cover?
   Permanent or almost permanent ice formations of lakes (continuous ice sheets that cover the entire surface for all of the year or which recede to part of the lake during summer accompanied or replaced by floating ice blocks, rafts and hummocks) (path = Yes) are distinguished from waterbodies with open water, which may or may not have occasional ice cover.
Answers:
Yes Factsheet icon [ C1.7 ] No (Question c02 )


Question c02 :   Temporary?
   Seasonal and otherwise temporarily-filled lakes, ponds and pools (path = Yes) are separated from surface water of more permanent character. Note that the wet phase only of temporary standing waters is characterised here. The habitat in its dry phase is normally characterised under C3. Note that temporarily flooded meadows and riverine forests are characterised as grassland and forest respectively.
Answers:
Yes Factsheet icon [ C1.6 ] No (Question c03 )


Question c03 :   Saline?
   Inland saline and brackish lakes and pools are separated (path = Yes) from waterbodies with freshwater.
Answers:
Yes Factsheet icon [ C1.5 ] No (Question c04 )


Question c04 :   Trophic status
   Standing waters are separated on the basis of their trophic status; oligotrophic waters, of low nutrient status, usually on hard, acid rock with high oxygen concentration in the hypolimnion; mesotrophic waters, intermediate between oligotrophic and eutrophic waters; eutrophic waters with high productivity and potentially low oxygen concentration in the hypolimnion; dystrophic waters which are rich in humus, often with a brown colour.
