Figure 2. 304, 192203. At all sample plots, regeneration of Douglas fir was coexisting with regeneration of other species thus not developing toward monospecific stands. Thanks Richard D. 0518Thanks for the email and it's humorous tone and yes (Douglas Fir) trees arrived in good condition and looking forward planting them. Large-scale forest fires in the tropics (e.g., Ferrante and Fearnside, 2020), a still high rate of deforestation in many countries due to land-use change (Bologna and Aquino, 2020), and the effects of climate change in combination with pests (Linnakoski et al., 2019) call for immediate action. DeliveryDue to courier unpredictability, we advise having your trees delivered AT LEAST 3 days before you actually need them. Thus, the presence of Douglas fir regeneration is positively correlated with browsing of Norway spruce and oak, but negatively correlated with the distance to the next diaspore source and with the diffuse light availability [indirect site factor (%); Figure 5]. Significant correlation of Douglas fir regeneration (all height growth classes and for distance to diaspore source only class I) with recorded environmental factors, with beta, standard error (SE), t value (t), significance (Sig.

The data of the water regime showed that roughly 85% of the sample plots with Douglas fir regeneration belong to sites with fairly low water deficit during summer (transpiration difference between potential transpiration optimum and actual transpiration of forest stands, TDiff of only 010 mm according to Mette et al., 2019). Sci. Mitt. 140, 883899. Speidel, G. (1955). As a precautionary measure, Douglas fir should, nevertheless, not be grown near dry and species-rich grassland, sparsely stocked rocky slopes or xerothermic open oak forests (Ammer et al., 2016). (1996). The tree species can run out of control of silvicultural management and thus, might threaten native ecosystems during biological invasion (e.g., Terwei et al., 2013; Brundu and Richardson, 2016; Langmaier and Lapin, 2020). On the contrary, across the relatively broad site conditions of the Spessart mountains, there were no indications that stands of other tree species worth of protection are being invaded by Douglas fir.

Woodburning ChartIf you are one of those lucky people that lead an eco lifestyle (VERY jealous if you are) and want to buy trees to burn, then maybe our wood burning chart (excel spread sheet) will help you decide. In the southern Spessart, however, selected habitats which are protected under Annex 1 of the EU Habitats Directive are included in the study area as these sites would be under threat of the invasion of a non-native species, thus losing its unique natural and near-natural character, respectively. By considering only the presence of Douglas fir regeneration in height growth class I as dependent variable, the number of trees is positively correlated with the occurrence of rowan (height growth class I), Weymouth pine (all height growth classes) and European Larch (height growth class I). Different facets of tree sapling diversity influence browsing intensity by deer dependent on spatial scale. the perception of an alien tree species through the centuries. (1953).

Our methodological approach encompasses three steps which are (1) the systematic selection of sample sites, (2) field sampling and analysis of the environmental factors affecting the regeneration of Douglas fir, and (3) the assessment of the potential invasiveness of Douglas fir in the Spessart mountains. Additional monitoring and careful observations might be necessary in order to timely cope with potentially invasive developments due to time-lag effects and increasing cultivation area. By analyzing correlations between Douglas fir regeneration and the regeneration of other tree species [OLS regression (1)], we found that the number of Douglas fir individuals on the plots (all height growth classes) is positively correlated with the occurrence of Norway spruce (height growth class I) and negatively correlated with the occurrence of Weymouth pine (height growth class III) (Table 3). doi: 10.17875/gup2015-843.

The influence of seed dispersal and predation on forest encroachment into a California grassland. As discussed earlier, Douglas fir does not need much light for successful establishment of its natural regeneration. (2015), species are considered as invasive if they have negative impacts on site conditions, high reproductive potential, high spreading potential, suppressing capacity, and limited management options. Res. To check for non-linear dependencies, we secondly analyzed the scatter plots for each metric independent variable and the dependent variable. Invasion of northern oak woodlands by Pseudotsuga menziesii (Mirb.) Figure 5. Manag. Therefore, both reproductive and spreading potential of Douglas fir in the Spessart are not considered as high, supporting recent assessments by Vor et al. This means that planting can be carried out at any time of the year, provided they are watered in periods of drought, compared to bare-root plants which can only be planted during the plants normal dormant period (November to March). Applied Linear Regression Models, 4th Edn. Thus, our results confirm earlier findings that had identified the same environmental factors as important drivers of Douglas fir regeneration in Central Europe (Isaac, 1938; Lavender et al., 1968; Bindewald et al., 2021). 0814.

(2011). (2011). Consequently, we focus with our investigations on the northern upper Spessart. (2019). Stands with dominating Douglas fir were selected from geodata provided by the forest administration, whereby adjacent areas of these stands were considered being sites of potential regeneration. Consequently, Tilio-Acerion forests of slopes, screes, and ravines (EU Code: 9180), siliceous rocky slopes with chasmophytic vegetation (8220), and Nardus stricta grasslands on siliceous substrates in mountain areas (6230) were included.

The abundance of established Douglas fir regeneration can function as a proxy for the success rate of reproductive efforts (Vor et al., 2015). Especially, when mixed with the shade-tolerant European beech, the invasiveness potential of Douglas fir in Central Europe can therefore be considered very limited and controllable at any time. Pflanzensoziologie. Both OLS regressions revealed valid models (p < 0.05), the explanatory value (r2 = 0.321) when using the height growth class I of Douglas fir as dependent variable was slightly lower than for the OLS regression with all height growth classes of Douglas fir as dependent variable (r2 = 0.390). Empfehlungen fr den anbau eingefhrter waldbaumarten. doi: 10.3120/0024-9637200552[21:TIOSDA]2.0.CO;2. More than half of the plots (56%) were dominated by natural regeneration of Norway spruce. Although Douglas fir seedlings have been reported up to 2 km away from a seed source, the majority of seeds fall within 100 m of seed parent trees (Barnhart et al., 1996; Broncano et al., 2005; Kennedy and Diaz, 2005). This conclusion is in line with the large-scale assessment of Bindewald et al. We sampled the regeneration of Douglas fir by differentiating height growth classes in various forest-stand types, taking the distance from mature mother trees, abiotic site conditions (e.g., water balance and soil properties), light supply, forest-stand characteristics, ground vegetation, and browsing pressure into account. (1938). Such systems are not supposed to substitute natural systems, but may contribute in reducing the pressure on the few undisturbed ecosystems. We are grateful for the provision of forest inventory data by the Bavarian State Forest Research Center (Regensburg, Germany). By applying the invasion model of Heger (2001), all four steps can be revealed for Douglas fir in the Spessart mountains which means that the non-native species is present (step 1), can establish spontaneously (step 2) as well as permanently (step 3), and a spread and colonization can be observed on many sites in the study area (step 4). For. (2002). Historically, forests in the Spessart underwent multifaceted phases of anthropogenic influences, with a spatially varying impact of forest glassworks, hunting, agriculture, and subsequent afforestation of degraded forest sites about 200 years ago.

Of note is its foliage which when crushed releases an rahter attractive, aromatic citrus scent. Forest inventory-based assessments of the invasion risk of Pseudotsuga menziesii (Mirb.) Besides its benefits and opportunities for forestry and timber production in Central Europe, however, concerns have been raised on its potential invasiveness and subsequent trade-offs for forest ecosystems such as, e.g., the change of the abiotic and biotic environment (Barnhart et al., 1996; Knoerzer, 1999; Goner and Simon, 2002; Goner and Utschik, 2002; Nehring et al., 2013; Wohlgemuth et al., 2021). J. During Spring and Summer, you can do this for up to 3 weeks. However, results point to a positive relationship of spontaneous Douglas fir regeneration at moist and light sites as well as in close distance to potential seed trees. (2003). From these results, we assess and discuss the potential invasiveness of Douglas fir in the forests of the Spessart mountains and derive recommendations for the management of this non-native tree species. Christmas tree planting for a commercial crop is around 1m. Among the tree regeneration were the most abundant native, broad-leaved, and late-successional trees beech and oak, native pioneer species (e.g., rowan and Scots pine) as well as non-native coniferous tree species, which are cultivated in the forests such as, e.g., Weymouth pine, silver fir, and European larch (Figure 4). Die Naturverjngung der Douglasie im Bereich des Stadtwaldes von Freiburg. (1877). New York: Springer. Additionally to the above-mentioned coniferous species, Douglas fir has been promoted in the northern upper Spessart as forest tree, dating back to the second half of the 19th century (Mergner, 2018). No use, distribution or reproduction is permitted which does not comply with these terms.

Woodland Design Principles - The creation of a Pinetum or Conifer collection. The invasiveness or potential invasiveness was assessed according to the model from Heger (2001; Figure 2) and the survey by Vor et al. Our findings are based on data from 626 randomly and 105 occasionally located sample plots. However, if temperature increase due to climate change continues, a decline in productivity for Douglas fir is expected in already warm and dry regions (Eckhart et al., 2019). Podrzsk, V., Martink, A., Matejka, K. J., and Viewegh, J. (2014, p. 22) that the existing studies suggest that forest ecosystems in Central Europe are able to deal with the introduction of Douglas fir comparably well. We aim to investigate the environmental conditions on those sites where natural Douglas fir regeneration is expected to occur outside of already existing stands. Analyses of the scatter plots revealed no non-linear dependencies, the residual analyses revealed no noticeable patterns, and the KolmogorovSmirnov test proved the normal distribution of the dependent variables Douglas fir regeneration (all height growth classes) and Douglas fir regeneration (height growth class I) [asymp.

Based on the criteria of Vor et al. Data were then calculated for an area of 1 ha. The analyses of 161 sample plots where natural regeneration of Douglas fir was found showed that 95% of all seedlings and saplings had established in a distance of less than 85 m to the next diaspore source (Figure 3). In this region, Douglas fir has a long silvicultural tradition, dating back to the 1880s (Mergner, 2018). This supports effective management measures.
