Significant works of forestry research from the second half of 20th century in Slovakia

The contribution is published on the occasion of the 120th anniversary of the establishment of a forestry research organisation in Slovakia and the 100th anniversary of the establishment of the Czechoslovak Republic. We present important forestry research works, which were written by former (no longer alive) workers of the Forest Research Institute (FRI) in Zvolen in the second half of 20th century. The works (30 works in total) were divided into seven scientific areas: biology and silviculture (five works), forest protection (four works), forest management (five works), forestry mechanisation and harvest-production technologies (four works), forestry economics (five works), hunting (three works), natural environment (four works). First, summary information on selected works in a specific area was presented. Then, individual works from the specific scientific areas were characterised in more detail. Their value for the development of science and research as well as for the practical forestry was presented. Moreover, their importance for the present time was addressed. The paper presents only a very limited selection of a great number of works by FRI workers published in the second half of 20th century. The table with the information on the periods, when the individual significant researchers worked at FRI, is presented at the end of the paper.
