(4030) – HABITATS DETERMINING
TYPOLOGY
European Dry Heaths

Ecological and physical characterisation of the
typology.
Formations of considerably varied appearance can
manifest themselves either as sparse woods with low
and scattered trees or as thick shrubs especially of
brooms and young trees, common aspen and Scots pine,
either as moorlands dominated by heather, or high
grasses characterised by molinia grass or low
grasses.
Each type is a manifestation of an ecosystem and its
story.
The presence of an abundant and well-developed woody
component indicates an undisturbed evolution of
plant life. On the other hand, an abundant
herbaceous vegetation often results from severe
disturbances such as fire.
Low grasses are usually limited to small depressions,
often of artificial origin which favour the growth
of higrophyle grasses.
They are present on plains, especially on flat
highlands at an altitude of between 200 and 450
metres and on low mountains.
Soils are evolved (paleosoils) acids, with
insufficient nutritional elements and with abundant
loam and clay which cause bad drainage and frequent
water stagnation.
Characteristic plant species include
tall moor grass (Molinia arundinacea), common broom
(Cytisus scoparius), the Sessile Oak (Quercus
petreae), heath grass (Danthonia decumbens), typical
cinquefoils (Potentilla erecta), the Scots Pine (Pinus
sylvestris), the Common Aspen (Populus tremula),
Alder Buckthorn (Frangula alnus), legumes (Genista
tintoria), Bracken Fern (Pteridium aquilinum), the
Marsh Gentian (Gentiana pneumonanthe), Wolf’s bane
(Arnica Montana), moor matgrass (Nardus Striata) and
the Northern Red Oak (Quercus rubra).
