Tilieta sensu Gor…akovskij 1972; Querceto-Tilietum.
Structural feature of the main community(ies) (layers, life-forms, etc.)
The tree layer, 16-25 m tall, is dominated by Tilia cordata; Ulmus glabra is added quite often (up to 30 % of the biomass), while Quercus robur and Acer platanoides are rarer. The degree of coverage of the tree layer is 60-90 %. The shrub layer is developed weakly (10-15 %), and the herb layer is relatively species deficient.

Importance for nature protection
Present state and development trend of natural vegetation (degree of endangerment)
Semi-natural lime forests are very resistant to anthropogenic influences. Rapid regeneration of the lime as a result of stump sprouting.
endangered communities, species worthy of protection in natural vegetation
Worthy of protection are nearly-natural forests as well as Cicerbita uralensis, Cypripedium calceolus, Cypripedium guttatum, Gymnadenia conopsea, Dactylorhiza fuchsii.
causes of endangerment
Timber harvesting.
required measures for protection and restitution
Preservation of semi-natural stands.
