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

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.
