English term or phrase: shelterwood
Definition from Temperate Forest Foundation:
The silvicultural method that gradually removes the trees from a given stand by a series of partial cuttings over a relatively short period of time. Eventually all overstory trees are removed, resulting in an even-aged stand.

Example sentence(s):
  • The shelterwood system involves several steps: control of competing understory vegetation, the shelterwood selection and final harvest cut. Warnell School of Forest Resources
  • The increased interest in shelterwoods for regeneration of spruce has led to an interest in how harvester productivity in shelterwood cuttings compares to productivity in clear felling. Journal of Forest Engineering
  • Forests can be regenerated by removing all but the best 40 to 60 trees and cutting the smaller, more poorly formed trees in what is called a shelterwood cut. When scattered large trees are left in a shelterwood cut, some tree species which are intermediate shade-tolerant trees such as northern red oak are favored. Virginia Department of Forestry

atvejiniai kirtimai


Definition from Miško savininkų asociacija:
Kirtimai, kai subrendęs medynas nukertamas ne visas iš karto, o iš pradžių jis praretinamas taip, kad po likusiais augti medžiais patektų daugiau šviesos ir susidarytų kuo geresnės sąlygos savaime želti naujiems medeliams, iš kurių vėliau bus formuojama nauja miško karta.

Example sentence(s):
  • Atvejiniai kirtimai gali būti ekonomiškai efektyvūs, jeigu yra tikslinių medžių rūšių savaiminis atžėlimas prieš arba tuoj po pirmojo kirtimų atvejo. - Saugomų teritorijų ir neplynų kirtim�  
  • Atvejiniais kirtimais medynas iškertamas 2–3 (4) atvejais per 10–20 (išskyrus ilgalaikius atvejinius kirtimus) metų. Atvejiniai kirtimai vykdomi sklypuose ar jų grupėse. Pagrindiniai atvejinių kirtimų tikslai – naujo tikslinio medyno suformavimas atžėlimu ir medyno išauginimo laiko sutrumpinimas bei racionalesnis medienos panaudojimas, kai medyną sudaro nevienodo brandumo medžiai. Atvejiniai kirtimai taip pat gali būti vykdomi siekiant sudaryti sąlygas vertingų medžių rūšių pomiškiui atsirasti bei nepageidautinų rūšių, ypač drebulės ir baltalksnio, atžaloms sunaikint. - Jungtiniai miškai
