Georgia <strong>52</strong> associations (forest types) are recognised while in the beech forests of the state forest<br />
fund, regulation on felling must be justified from the forestry and environmental points of view and<br />
is mainly based on characteristics of the specific types of beech forests (Gulisashvili 1964):<br />
Beech forests with rhodo<strong>de</strong>ndron sub-forest (Fagetum rhodo<strong>de</strong>ndrosum): Beech forests of this type<br />
are found in Western Georgia in shady damp parts of the mountains as well as in Eastern Georgia.<br />
These stands are highly productive.<br />
Beech forests with cherry laurel sub-forest (Fagetum laurocerasosum): They are spread in damp valleys<br />
of Western Georgia on steep slopes of all exposures. Vegetation inclu<strong>de</strong>s azalea, ilex, Caucasian<br />
bilberry etc., which are mixed together with cherry laurel in the subforest.<br />
Beech forest with <strong>de</strong>ad surface (Fagetum nudum): This is sufficiently wi<strong>de</strong> type of forest, and is found<br />
mainly in the form of high-<strong>de</strong>nsity stands. Beech forests of this type are presented in the lower and<br />
upper belts of the distribution of beech forests:<br />
Beech forests with <strong>de</strong>ad surface in the lower belt are spread on the northern mountain slopes of mean<br />
inclination at the altitu<strong>de</strong>s 600 – 800 m. In this type of beech forest due to the high <strong>de</strong>nsity of canopy,<br />
natural regeneration is very limited.<br />
Beech forests with <strong>de</strong>ad surface in the middle belt are spread within the altitu<strong>de</strong>s at 1,000 – 1,200 m,<br />
mainly on slopes of north-eastern exposures. The natural regeneration of beech by seed in these<br />
stands of high <strong>de</strong>nsity is unsatisfactory.<br />
Beech forests with star grass cover (Fagetum asperulosum): They are found mainly within the altitu<strong>de</strong>s<br />
800 – 1,500 – 1, 00 m. This is very wi<strong>de</strong> spread type of forest and may be of two sub-types.<br />
Beech forests with star grass cover at the middle belt are found within the altitu<strong>de</strong>s 1,000 – 1,400 m.<br />
Natural regeneration (by seeds) is satisfactory. Productivity of stands is high (growth class I-II). Here<br />
grass cover is relatively sparse.<br />
Beech forests with star grass cover of the upper belt are found at altitu<strong>de</strong>s 1,500 – 1,800 m, mainly<br />
on the northern exposures of mean (15 – 20°) inclination. Hornbeam and lime are mixed with beech<br />
and here a sub-forest is seldom found. Grass cover is weakly <strong>de</strong>veloped.<br />
Beech forests with fescue grass cover (Fagetum festucosum): Vertical distribution of this type of beech<br />
forest according to height may be divi<strong>de</strong>d into three belts, in particular:<br />
Beech forests with fescue grass cover of the lower belt. This type is found at the altitu<strong>de</strong>s 1,000 –<br />
1,300 m, on steep southern mountain slopes. Associated species are hornbeam, common maple, lime<br />
etc. which are mixed with beech in these stands. Here the sub-forest is less <strong>de</strong>veloped. These stands<br />
are of high productivity (growth class I-II).<br />
Beech forests with fescue grass cover of the middle belt are found at altitu<strong>de</strong>s of 1,300 – 1,500 m, on<br />
the slopes of southern and northern (less) exposed sites. The different ages of the stands <strong>de</strong>termine<br />
their biodiversity.<br />
Beech forests with fescue grass cover of the upper belt are found at 1,600 – 1,800 m, on the steep<br />
slopes (inclination 21 – 35°). These stands are mainly of beech with Nordmann fir and eastern spruce<br />
and are mixed with it in Western Georgia. Natural regeneration in medium <strong>de</strong>nsity beech forests of<br />
this type is satisfactory.<br />
One of the main <strong>de</strong>termining features of biological diversity of Georgian beech forests is their<br />
distribution according to the <strong>de</strong>nsity of stands.<br />
Stands of medium <strong>de</strong>nsity (0.5 – 0. ) mainly dominate in Georgian beech forests. It is noteworthy<br />
that low-<strong>de</strong>nsity stands occupy sufficiently large areas and the area of high-<strong>de</strong>nsity stands have<br />
