“…Its role is particularly assumed as a substitute for the declining Norway spruce, which is endangered by climatic changes at lower altitudes [7], and this species, native on some 11-15% of the Czech territory, shows many health problems, yet is at the same time the key species of Mid-European forestry [8,9]. The supply of Norway spruce timber will likely decrease in the near future [10]. Afforestation of agricultural lands constitutes a serious change in soil dynamics, including soil structure, organic matter and nutrient dynamics [11][12][13][14].…”

This study compares the quality of wood from two distinct sites in the Czech Republic-from former afforested agricultural land and forest land. We compared the properties of Norway spruce wood (Picea abies Karst.) and Scots pine wood (Pinus sylvestris L.), the most important domestic tree species, to Douglas fir (Pseudotsuga menziesii (Mirbel) Franco), a North American tree species and a potential substitute for the domestic spruce. Wood density, modulus of elasticity (MOE), modulus of rupture (MOR) and impact bending strength were the properties tested that were used for comparing tree species. Without taking into consideration the site, the highest density values from the tested tree species were obtained for Douglas fir (0.568 g·cm −3 ), followed by the pine (0.508 g·cm −3 ) and the spruce (0.463 g·cm −3 ). The Douglas fir also dominated in the remaining assessed properties, whilst the influence of site was not confirmed, with the exception of MOE and MOR, and only for the Douglas fir wood, wherein higher values were obtained for forest land. In terms assessed Douglas fir properties, it exceeds the domestic softwoods and represents a possible suitable replacement for them. The site only plays a role in terms of the Douglas fir, and only for certain properties.

“…In discussions on the suitability of tree species, Douglas-fir (Pseudotsuga menziesii) is often suggested as a tree species that is more resilient to pests, drought, and weather extremes compared to the Norway spruce. Its role is assumed to be mainly as a substitute for declining spruce, which is threatened by climatic changes at lower altitudes [2], leading to a likely decrease in the supply of spruce wood in the near future [3].…”

Two comparable sites with uneven-aged mixed forest stands with more than 20% Douglas-fir in the growing stock at an altitude of 650 m a.s.l. were selected. The physiological response of young trees to different light intensities was measured during the main growing season in three consecutive years, and four different light categories, which were determined from hemispherical photographs. The four light intensity categories were defined according to Indirect Site Factor (ISF%): in the open (A-ISF > 35%), at the outer forest edge (B-25% < ISF < 35%), at the inner forest edge (C-15% < ISF < 25%), and under complete canopy under mature forest stand (D-ISF < 15%). Climate data were obtained from the Royal Netherlands Meteorological Institute ‘Climate Explorer’ website (http://climexp.knmi.nl). For the intensive micrometeorological observations, four monitoring sites were established along the elevation gradient at each site during summer and late fall to record relative humidity (RH%) and temperature (°C) with a 30 min recording interval sequence. Measured assimilation responses (A) and light use efficiency () at one site followed the expected pattern, while humidity combined with microsite conditions proved significant in explaining the specific response of young Douglas-fir to the different light intensity at the other site. For higher survival and optimal future development of Douglas-fir in the changing environment, microsites with higher capacity for storage moisture and favorable microclimate should generally be preferred to exposed and dry sites.

“…The study area encompassed 3,884 km² that spanned the South Bohemian, Vysočina, and South Moravian regions of Czechia as well as a portion of northern Austria, given the configuration of the reference area. The forests are classified relative to commercial exploitability with high-intensity forest management plans and guidelines in place (Synek et al 2014). The forest clear-cutting has resulted in a landscape mosaic composed of a high degree of heterogeneity.…”

Conservation, Connectivity, and Coexistence: Understanding Corridor Efficacy in Fragmented Landscapes

Long

View full text Add to dashboard Cite

Conservation corridors, areas of land connecting patches of natural land cover, are frequently cited and implemented as a restorative strategy to counteract fragmentation. Current corridor ecology focuses on experimental corridor systems or designed and built conservation corridors to assess functionality. Such systems and designs are typically short, straight swaths of homogenous land cover with unambiguous transitions between patches. Quantifying the degree to which amorphous landscape configurations, tortuosity, and heterogeneity of land cover and land uses within the corridor has on functional connectedness is a crucial yet overlooked component of corridor efficacy studies. Corridor literature lacks a robust and repeatable methodology for delineating existing landscape elements, recognizing arbitrary edges, and identifying the start and end of ambiguous transitions between the patches and corridor. Using a set of landscapes being studied as part of a global assessment of corridor efficacy, I designed a workflow that standardizes the boundary of corridor-patch interfaces. The proposed method is a quantitative and repeatable approach that minimizes the subjectivity in corridor delineations. This research investigates the degree to which the existence of a corridor modifies the structural and functional connectivity between patches connected by a corridor compared to an intact reference area.
