Reforestation in our demo area in Vysocina region

In the Vysocina region, mature Norway spruce stands were heavily infested by bark beetles. It resulted in massive salvage logging and an abrupt decrease of the area of older coniferous stands by 20%. In one of the most affected forest districts, Ledeč nad Sázavou (Forest of the Czech Republic; Lesy České republiky s.p.), salvage felling in the period 2018–2022 amounted to 2 219 333 m3. Affected trees were continuously removed, and sites were prepared for restoration. The main restoration measures are natural and artificial regeneration (planting and seeding) of site-specific tree species of local provenances (following national legislation – decree 456/2021) and subsequent weed control. In the Czech demo areas, planting took place in the spring and autumn of 2022. Protection through the fencing of broadleaved and Abies alba was necessary to prevent game browsing. The main tree species used for reforestation are Quercus petraea, Fagus sylvatica, Acer pseudoplatanus, Picea abies, Alnus glutinosa, Pinus sylvestris and Prunus avium. The design of reforestation is based on site-specific conditions, the mosaic of site types and targeted tree species composition. In the coming years, we plan on improvement of afforestation in case of failures, mechanical weed control, and consequent use of repellents outside the fenced areas.
