The study presents plant interception understood as a process of retaining rainfall over the entire surface of the plant. The objective was to collect and prepare data presenting changes in the amount of rainwater reaching the forest floor, and to inference on the diversity of water capacity within canopy of a single tree. A characteristic feature of an interceptive tank is the lack of tightness,...
The objective of the study was to analyse the site index (SI) of Douglas fir (Pseudotsuga menziesii) stands in relation to the forest habitat type, soil type and relief characteristics. We utilised information available in the Information System of the State Forests in Poland that included selected parameters describing habitat conditions and dendrometric characteristics of Douglas fir stands. In...
Pinus × rhaetica is holoarctic species, which represents mixed morphological features from both P. uncinata and P. mugo. It is a typical species living in peat−bogs in highlands and it is endangered by drainage and the decline of its natural area. By now, the greatest population of peat−bog pine is living in the Wielkie Torfowisko Batorowskie peat−bog, but its health condition is alarming. In Poland...
Mistletoe is semiparasite adversely affecting the functioning of their hosts especially at water management level. So far, there have been no reports about the impact of mistletoe on seeds from any host. The aim of the work was to evaluate the effect of the presence of mistletoe on the quality of the seeds of Scots pine (Pinus sylvestris). Unopened cones from infected and uninfected trees were collected...
The study presents the assessment of damage to beech stands using four methods, including that taking into account the radial increment. The condition of stands in 2016, and the growth response of trees to the environmental changes since 1956 are described. The measurements and observations were carried out on 18 sample plots (tab. 1) located in south−western Poland. The mean defoliation accounts...
We analyzed data on wood resources of small−leaved lime in the forests managed by the State Forests, depending on the type of occurrence, age of trees, type of forest site, soil and region of the country. Particular attention was paid to the mature and close−to−mature stands with lime occurring in the overstory and undergrowth. We pointed regions and habitat conditions that are most favorable for...
The work concerned the ascomycetous fungus Eutypella parasitica, which for several decades has been present in North America, where it attacks various species of maple. In 2005, for the first time it was recorded in Europe, in Slovenia. Later on it was found in Austria, Croatia, Germany, Hungary and the Czech Republic. In 2016 for the first time the species was reported in Poland, in the Polish−Czech...
