Problems associated with reproducing white cedar in eastern Ontario

Abstract

White cedar (Thuja occidentalis L.) in eastern Ontario has difficulty regenerating after a cut on various sites. There are three primary and three secondary factors influencing this problem on both upland and lowland sites. The primary factors are slash accumulation after harvest, improper cutting techniques and litter layer pH. Moisture fluctuations, frost heaving and wildlife browsing are the secondary cedar regeneration reducing factors. Upland sites are slower to re-establish after a cut than lowland sites, due to the lack of moisture and exposed mineral soil. Lowland sites are wetter than upland sites, and as a result regenerate and develop faster.
