  1. Remove woody debris after timber harvest

    A replicated, controlled study in 2000-2003 in temperate coniferous forest in Québec, Canada (Lorenzetti et al. 2008) found no effect of woody debris removal and raking in artificial gaps on the survival of yellow birch Betula alleghaniens seedlings. Seedling survival was similar between treatments (debris removal and raking: 45-50%; removal: 22-40%; control: 23-38%). Data were collected in 2003 in six control, six debris removal (mechanically pushing all debris to the edges of the gap), and six removal and raking (pushing all debris followed by raking) artificial forest gaps (900 m2). Gaps were created and treatments applied in 2000.
