Like in the Beskid Śląski and Żywiecki Mts., the dieback of Norway spruce stands takes place also in the Beskid Mały range. This process is clearly more intensive and occurs over a longer period of time. The conversion of these forests during the study period (2004−2016) resulted in a significant increase in the proportion of beech and fir as well as other, mostly deciduous tree species (tab. 1)....
The aim of the study was to analyse (on the basis of the data from the State Forests Information System) the changes occurring in the Bieszczady forests in the period of 2007−2016. One of the processes taking place in the study area is the withdrawal of grey alder stands and the appearance of natural regeneration of mainly beech and fir, and in a smaller proportion spruce (fig. 1). Another natural...
The study presents a method of planning species composition of forest stands in mountain areas on the example of Beskid Niski Mts. (south−eastern Poland). The focus was on the species composition of forest stands growing in different conditions, taking into account the type of forest habitat and terrain characteristics: altitude, exposition and slope. The research was based on data stored in the Information...
The aim of this research was to assess damage to three important forest−forming trees species in the mountains – spruce, fir and larch, and to study their increment reaction to changing environmental conditions. Research concerned forests under the management of four forest districts located in the Western Sudetes (SW Poland). Index W ranging from 0 to 3 was used for the assessment of the damage to...
