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 کاملCrown Condition as an Indicator of the Incidence of Root Rot Caused by Hetero basidion annosum in Scots Pine Stands
Trees in three Scots pine stands seriously infected by Heterobasidion annosum were classifi ed according to their crown condition into four classes, from healthy to dead trees. After cutting the stands, the classifi cation was compared with the symptoms of annosum root rot on stump surfaces (pitched area) and with the extension of decay in the roots of excavated stumps. When dead trees were inc...
متن کاملthe condition of scots pine stands in lahemaa national Park , estonia 25 years after browsing by moose ( Alces alces )
The effects after 25 years of moose browsing on Scots pine stands in Lahemaa National Park were evaluated, emphasizing economic damage. A re-evaluation in 2001 examined stands that had been evaluated in 1975–1976. Moose damage significantly affected the tree species composition which changed over time as pine dominance increased and the number of mixed stands declined. The smaller proportion of...
متن کاملHeight Distributions of Scots Pine Sapling Stands Affected by Retained Tree and Edge Stand Competition
The paper focused on the height structure of Scots pine saplings affected by (1) retained solitary pine trees or (2) a pine-dominated edge stand. The study material in (1) and (2) consisted of ten separate regeneration areas in southern Finland. In (1) 2-m radius study plots were located at 1, 3, 6 and 10 m distances from 10 systematically selected, solitary retained trees in each stand. In (2)...
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...
