Object & Deliverables


This project evaluated the characteristics of mounds produced by the Dual Path Mounder and related these characteristics to tree performance and reforestation success.

Plot data was collected from 1995 to 1999 from fourteen established plots in five cutblocks. The plot data included mound characteristics, soil nutrient, soil pH, soil temperature, soil moisture, seedling position on the mound and in relation to the mound, competition, seedling survival and growth, and precipitation.


Final Report

The results of this study indicate that mounding is an effective operational forest management practice for enhancing white spruce growth and survival. Mounding is likely to be most useful in more poorly drained sites where the treatment is able to increase soil temperatures. However, mounding upland sites may also provide benefits in terms of seedling establishment and performance. Seedlings planted on mineral mounds in control areas appeared to have better root growth, which correlates to better survival and overall growth. Mounds were found to provide approximately two growing seasons of competition control from Calamagrostis canadensis (marsh reedgrass).
