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.

Question e01 :   Heavy metal soil?
   Grasslands with metalliferous soils are separated (path = Yes) from those on calcareous, neutral or acid soils without a high heavy metal content.
Answers:
No (Question e02 ) Yes Factsheet icon [ E1.B ]


Question e02 :   Mediterranean, arid and overgrazed?
   Very dry over-grazed Mediterranean habitats (ermes), characterised by unpalatable tall herb species, are distinguished (path = Yes).
Answers:
Yes Factsheet icon [ E1.C ] No (Question e03 )


Question e03 :   Soil reaction
   Base-rich grasslands are distinguished from base-deficient dry grassland habitats.
Answers:
base-rich (Question e04 ) base-deficient (Question e09 )


Question e04 :   Embryonic soil, open vegetation?
   Habitats on embryonic sandy or detritic soils with open pioneer vegetation (path = Yes) are distinguished from those on more developed soils. Note that very sparsely vegetated scree habitats are categorised under H2 and sparsely vegetated sandy ground under H5.3.
Answers:
Yes Factsheet icon [ E1.1 ] No (Question e05 )


Question e05 :   Geographical region
   Perennial grasslands, often nutrient-poor and species-rich, on calcareous and other basic soils of the nemoral and steppe zones and of adjacent parts of the subboreal and submediterranean zones are separated from grasslands of the Mediterranean zone.
Answers:
nemoral and steppe Factsheet icon [ E1.2 ] Mediterranean (Question e06 )


Question e06 :   Nitrophilous annuals?
   Mediterranean grasslands dominated by annuals on somewhat enriched soils are separated (path = Yes) from perennial grasslands and xeric annual grasslands on poor dry soils (path = No).
Answers:
Yes Factsheet icon [ E1.6 ] No (Question e07 )


Question e07 :   Montane?
   Open perennial grasslands of the montane thermophilous oak level of the Mediterranean climatic zone are separated (path = Yes).
Answers:
Yes Factsheet icon [ E1.5 ] No (Question e08 )


Question e08 :   Vegetation height
   Short xerophile Mediterranean grasslands, typically composed of grasses less than 60 cm high, are distinguished from tall Mediterranean grasslands and Artemisia steppes.
Answers:
short Factsheet icon [ E1.3 ] tall Factsheet icon [ E1.4 ]


Question e09 :   Open?
   Open acid and neutral grasslands, usually pioneer formations developing on sand, including inland dunes, are separated (path = Yes). Note that habitats with <30% vegetation cover are categorised under H.
Answers:
Yes (Question e10 ) No (Question e11 )


Question e10 :   Biogeographic region
   Mediterranean dry open acid and neutral grasslands are separated from those in other biogeographic regions.
Answers:
other Factsheet icon [ E1.9 ] Mediterranean Factsheet icon [ E1.A ]


Question e11 :   Biogeographic region
   Mediterranean dry closed acid and neutral grasslands are separated from those in other biogeographic regions.
Answers:
