Anna Bamberger,Maribel Fernándezhe Yukon. The major species are spruce, pines, balsam fir, white birch and trembling aspen often occurring in extensive monocultures. Wildfire is the driving successional force in the boreal forest and has remained so despite fire suppression activities and extensive harvesting. Insects and diseases

Hector Suzanne,Emmanuel Chaillouxare presented. In 2 out of 3 years the injury was substantial. Planted white spruce is injured during its first overwintering while naturally established seedlings are not. A brief summary of 1992/93 post-winter assessments of 1-year old operationally established plantations is also presented. Most

François Degrave,Tom Schrijvers,Wim Vanhoofmonoliths were taken to the laboratory and received prescribed burning, leading to 100%, 75%, 50%, 25%, and 0% organic horizon removal. One half of each monolith contained ashes generated from burning whereas the other half was kept ash-free. Each half of every monolith was sown with jack pine seeds

Analysis of Linear Hybrid Systems in CLP,ation on geomorphological site characteristics and stand parameters, indices are determined using a specific criterion that describes the forest regeneration process. Using these indices as model inputs, clearcuts and burns can be classified; within each stratum the natural forest regeneration proce

https://doi.org/10.1007/978-3-031-45784-5Selective cutting is one of many harvesting methods alternative to clear-cutting. Both the influence on different ecological systems and the effect on forest productivity of this harvesting method are important. In this study, the productivity in 16 long-term experimental plots in selectively cut Norway spruce (.) forest is analysed.
