FPInnovations conducted a Mechanical Site Preparation trial with a Lamtrac 8290Q mulcher near Okanagan Falls, B.C. The mulcher was tested on three sites: moderate slope with heavy grass competition; moderate slope with high stumps and moderate to high slash levels; and steep slope with low to moderate slash levels. The Lamtrac mulcher had some difficulty with heavier slash loads, but was able to create acceptable microsites at the target density of 1000–1200 microsites/ha under the three different site conditions.
