<strong>Forest</strong>s, their status <strong>and</strong> their socio-economic importance<br />

Slovakia occupies the western part <strong>of</strong> the Carpathian Mountains. About 65% <strong>of</strong> the territory <strong>and</strong> thus a large<br />

proportion <strong>of</strong> forests has a mountainous character. The area <strong>of</strong> forests in Slovakia is 19,990 km 2 what equals<br />

41% <strong>of</strong> the total country’s territory (49,036 km 2 ). Another 1, 775 km2 <strong>of</strong> forests are found on ab<strong>and</strong>oned<br />

farml<strong>and</strong>s (<strong>Forest</strong> Information Center, 2001). The forestry sector is administered by the Ministry <strong>of</strong> L<strong>and</strong><br />

Management. The nature <strong>and</strong> environmental conservation comes under the Ministry <strong>of</strong> Environment.<br />

Categories <strong>of</strong> utilization <strong>of</strong> forest st<strong>and</strong>s are: 73% forests with predominating production function, 15%<br />

protective forests, <strong>and</strong> 17% forests with special functions (watershed areas, nature conservation, recreation<br />

forests). The average growing stock is 255 m 3 .ha- 1 . It increased by 50% during the past 50 years. The net annual<br />

increment was 13.86 million m 3 in 1996. In spite <strong>of</strong> these considerable increases, the total annual cut<br />

represented 5-7 mil. m3 in the 1990ies.<br />

Restitution <strong>of</strong> ownership has resulted in a broad variety <strong>of</strong> ownership types, increased number <strong>of</strong> owners <strong>and</strong><br />

users. Approximately 44% <strong>of</strong> forests is owned by non-state bodies or private persons. Restitution <strong>of</strong> another<br />

8% is in progress. The state-owned forests represent 42%. Approximately 6% <strong>of</strong> forests remain un-reclaimed,<br />

with unknown owner or non-reclaimable upon valid legislation. Medium-size estates with average size 100-<br />

700 hectares predominate in the category <strong>of</strong> non-state forests. A considerable part <strong>of</strong> forests (489,000 ha or<br />

24% <strong>of</strong> forest area) is in a shared ownership. Small holdings up to 5 hectares (average size 1.06 ha) cover only<br />

1.3% <strong>of</strong> forest l<strong>and</strong>.<br />

Contribution <strong>of</strong> forestry to the gross domestic products decreased from 1.2% in the beginning 1990’ies to<br />

0.66% in 2000. Total contribution to the GDP <strong>of</strong> forestry, wood processing, pulp <strong>and</strong> paper industries, is<br />

estimated to 8.5%, however. Slovakia is a net exporter <strong>of</strong> nearly all forest <strong>and</strong> wood-derived products.<br />

Both quantitative <strong>and</strong> qualitative indicators, except <strong>of</strong> those related with forest health due to high air pollution<br />

<strong>of</strong> trans-boundary origin, show that the management <strong>of</strong> forests is done in a relatively sustainable way. In the<br />

scores published by the WWF in 2000, the care <strong>of</strong> forests in Slovakia was ranked at the third to fifth position<br />

among the European countries. In spite <strong>of</strong> this fact, there are several problems which make promotion <strong>of</strong> more<br />

nature-conforming forestry practices difficult. These are related especially with the high share <strong>of</strong> incidental<br />

felling, which represents more than 50% <strong>of</strong> the total annual cut throughout the 1990’ies.Their prevalence over<br />

planned regeneration felling is an obstacle to regular forest management <strong>and</strong> systematic forest regeneration.<br />

<strong>Forest</strong> Vegetation<br />

Large vertical variation <strong>and</strong> transitional position between the oceanic <strong>and</strong> continental parts <strong>of</strong> Europe<br />

contribute to the large forest ecosystem diversity. The forest classification which is routinely used in the<br />

forest management planning (Zlatnik 1959), recognises 350 forest types grouped into 55 associations <strong>and</strong><br />

eight forest vegetation zones. Main forest ecosystems include riverain forest vegetation, oak <strong>and</strong> mixed oakbeech<br />

forest, pure beechwoods, mixed fir-beech, spruce-fir-beech <strong>and</strong> subalpine spruce forests, <strong>and</strong> the<br />

mountain pine dominated vegetation at the alpine tree limit. The share <strong>of</strong> broadleaves in the overall species<br />

composition is 56,9%, with beech dominating (29,6) <strong>and</strong> oaks second (13,7%). The share <strong>of</strong> Noble<br />

Hardwoods (maples, ash, elms, alders, limes, wild fruit species) is 4.1%. Conifers are represented by Norway<br />

spruce (27,5%), silver fir (4,6%) <strong>and</strong> pines (7,7%)<br />
