Thinning Response and Growth Trends of Seeded Scots Pine Stands at the Arctic Timberline
Growth patterns and reactions of Scots pine (Pinus sylvestris L.) to thinning in extremely harsh climatic conditions were studied in two seeded Scots pine stands located on the arctic timberline. Coniferous trees usually do not form closed stands at the timberline, but occur only in scattered tree groups. The trial was established in two stands in 1985–1986 when the trees were at an age of 47 a...
متن کاملFine root biomass and production in Scots pine stands in relation to stand age.
We determined fine root biomass and production of 15-, 35- and 100-year-old Scots pine (Pinus sylvestris L.) stands during three growing seasons. Fine roots were sampled by the soil core method. Mean (+/- SE) annual fine root biomass of Scots pine in the 15-, 35- and 100-year-old stands was 220 +/- 25, 357 +/- 21 and 259 +/- 26 g m(-2), respectively. Fine root biomass of the understory vegetati...
متن کاملLeaf area index and canopy strati cation in Scots pine ( Pinus sylvestris L . ) stands
In order to assess the contribution of each layer to eVective leaf area index (LAI) in strati ed forest canopies, two Scots pine stands were selected in Haguenau forest, Alsace, France. One stand, 80 years old, had a sparse tree layer and a dense herb layer. The other stand, 50 years old, had a closed tree layer and dense herb and shrub layers. Hemispherical photographs, taken at 10-metre inte...
متن کاملEvaluation of new silvicultural alternatives for scots pine stands in northern Spain
The new objectives which society is demanding of forest systems are leading to deep changes in their management. Aspects such as biodiversity preservation and recreation require forest management alternatives that are not based on the traditional management centered on the maximization of timber production. In this paper, we introduce five silvicultural alternatives different from those typical...
متن کاملArea-Based Mapping of Defoliation of Scots Pine Stands Using Airborne Scanning LiDAR
The mapping of changes in the distribution of insect-caused forest damage remains an important forest monitoring application and challenge. Efficient and accurate methods are required for mapping and monitoring changes in insect defoliation to inform forest management and reporting activities. In this research, we develop and evaluate a LiDAR-driven (Light Detection And Ranging) approach for ma...
