Continuous-cover forestry - a modern version of old-fashioned forestry
Selective cutting, shelterwood regeneration and gap felling are gaining popularity among Swedish forest owners who strive to find alternatives to the predominant clear-cut forestry. This film shows forest owners and contractors performing "clear-cut free" methods of forestry, and their motives. Besides, researchers present what we know about the methods. This is a film originally produced for the Swedish knowledge system Skogskunskap.se (Forestry knowledge). English narrator and English subtitles.

This is a great video!
Selective harvesting, shelter-wood and gap felling processes yield less profits on the on set, however the necessary silvicuture costs associated with clear-cutting: seed collection, seedling development, block site prep, tree planting , etc are significant. The discussed alternate harvest processes rely primarily on natural regeneration, and these process would save considerably for sustainability of the stands. Like your KZread channel; I can only understand the episodes containing English caption's, unfortunately :)

Not to forget the price difference between timber and pulpwood. Usually the selective cutting kind of methods are producing bigger % of timber than pulpwood the rotation time of a clear cut area. Väldigt bra video!
Too much emphasis on the economics of selective cutting forests, not enough emphasis on the ecological aspects. I was concerned to see tree harvesters utilized in selective cutting forests; no word being said on their impact on forest soil.

Yeah I'd love to see the ecological impact comparison instead of monetary points
