Shelterwood Felling in Late Successional Stands in Alberta's Rocky Mountain Subalpine Forest

The silviculture of the spruce-pine phase of the Alberta subalpine forest is discussed in relation to ecological problems and previous work.A trial of uniform shelterwood felling combined with seedbed preparation is described and followed to the third year.The abundant regeneration confirms the importance of shelter for spruce reproduction and suggests that practical methods be advised to provide it.Progressive strip cutting with scarification is suggested.
