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 [ E6 ] - Links directly to factsheet for E6

Additionally the diagram may be used for reference.

Diagram :

Question h01 :   Waterbody?

Underground waterbodies whether or not within caves are distinguished (path = Yes).

Answers: No ( h02 ) Yes ( 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.

Answers: Yes [ H1.7 ] No ( 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.

Answers: Yes [ H1.4 ] No ( 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.

Answers: Yes [ H1.1 ] No ( h05 )

Question h05 :   Restricted cross-section?

Passages restricted in cross-section in comparison with the spaces which they connect are separated (path = Yes).

Answers: Yes [ H1.3 ] No [ H1.2 ]

Question h06 :   Water flow

Standing waterbodies are separated from flowing waterbodies.

Answers: standing [ H1.5 ] flowing [ H1.6 ]
