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
Additionally the diagram may be used for reference.

Category : (H1 )Terrestrial underground caves, cave systems, passages and waterbodies
Diagram : Diagram icon

Question h01 :   Waterbody?
   Underground waterbodies whether or not within caves are distinguished (path = Yes).
No (Question h02 ) Yes (Question h06 )

Question h02 :   Man-made?
   Disused mines and man-made passages, including tunnels, often with smoothed or constructed surfaces (path = Yes) are distinguished from natural subterranean habitats. Note that active mines are characterised under J3.1.
Yes Factsheet icon [ H1.7 ] No (Question h03 )

Question h03 :   Volcanic origin?
   Caves formed from hollow basaltic tubes which result from the cooling of the surface of lava flows whose molten interior continued to flow are separated (path = Yes) from systems resulting from the action of water.
Yes Factsheet icon [ H1.4 ] No (Question h04 )

Question h04 :   Light-influenced and fluctuating temperature?
   Cave entrances which are influenced by light, and subject to fluctuating temperature, and which are unlikely to support a specialised fauna are separated (path = Yes) from cave interiors and passages beyond the reach of light and with a stable temperature.
Yes Factsheet icon [ H1.1 ] No (Question h05 )

Question h05 :   Restricted cross-section?
   Passages restricted in cross-section in comparison with the spaces which they connect are separated (path = Yes).
Yes Factsheet icon [ H1.3 ] No Factsheet icon [ H1.2 ]

Question h06 :   Water flow
   Standing waterbodies are separated from flowing waterbodies.
