(80) Height and cover of layers
(Chapter 8)
The estimated cover of the tree layer, the shrub layer, the herb layer and the moss layer
shall be submitted as % of the total sampled area.
The estimated cover of bare soil and litter shall be submitted as separate “layers” as %
of the total sampled area (effective surfaces covered by visible mineral soil and rocks
and visible litter (even if under shrubs, herbs or trees). The submission is done using up
to 4 digits for cover values with a floating decimal separator (between 0.01 and 9999).
The average height of the layers shall be given in meters using up to 4 digits
height (in m) cover (in %)

(81) Layers D_LAYER_SURFACE
(Chapter 8)
The following layers are defined.
Code
Layer
1 Tree layer (only ligneous and all climbers) > 5 m height
2 Shrub layer (only ligneous an all climbers) > 0.5 m height
3 Herb layer (all non-ligneous, and ligneous < 0.5m height)
4 Moss layer (i.e. terricolous bryophytes and lichens)
(82) Species code D_SPECIES_LIST NOCH AUSSTEHEND (>OG)
(Chapter 8, 10)
The species code exists of the code for the family (999), the code for the genus (999),
the code for the species (999). Family, genus, and species codes are separated by a dot
(“.”). Determination at Genus level, using ‘999’ as the code for sp/spp (‘species
pluralis’), is the minimal submission requirement; the “Other observations” text field
should be used for additional information (e.g. if there are obvious more than one
unknown species of the same Genus within the plot).
