Question b01 :   Wind-blown sand over peat?
   Machair (characterised by wind-blown calcareous sand with a predominance of shell fragments usually over peat, a low proportion of sand-binding vegetation and a long history of agricultural use) (path = Yes), is distinguished from other coastal sand habitats. Note that a machair complex is defined comprising units from B1, C and I.
Answers:
Yes Factsheet icon [ B1.9 ] No (Question b02 )


Question b02 :   Surface topography
   The topography of the surface distinguishes the abrupt mounds and hollows of sand dunes from more or less level sand beach habitats.
Answers:
dunes (Question b03 ) more or less level (Question b06 )

dry (Question b04 ) moist or wet Factsheet icon [ B1.8 ]


Question b04 :   Mobile?

Answers:
Yes Factsheet icon [ B1.3 ] No (Question b05 )


Question b05 :   Vegetation stratum
   Predominant vegetation type is used to distinguish between: dune grassland (herbs); dune heath (predominantly ericaceous dwarf shrubs); dune scrub (shrubs); and dune woodland (trees).
Answers:
herbs Factsheet icon [ B1.4 ] dwarf shrubs Factsheet icon [ B1.5 ] shrubs Factsheet icon [ B1.6 ] trees Factsheet icon [ B1.7 ]


Question b06 :   Above driftline?
   Driftline habitats characterised by lines of wave-deposited organic material colonised by annual angiosperms are distinguished (path = No) from mobile sand beaches above the driftline. Note that freshly deposited driftlines characterised by marine invertebrates and without annual vegetation are included in A2.
