“…As far as natural and landscape conservation is concerned, native woody species should be used for planting [20]. Several studies support using the data about potential natural vegetation for these purposes [21][22][23][24].…”

Abstract:On the arable land of the Rosovka Stream alluvium in the Czech Republic, a windbreak containing native woody species, was planted within a restoration project. This study evaluates the effect of that planting of three different tree sizes, on the rate of growth. The sizes of transplants employed in this study included small (1.0 -1.5 meters tall), medium-sized (2.0 -2.5 meters tall) and large (with a trunk circumference of 0.1-0.12 meters). The following native tree species, from the Eurosiberian region, were used: Quercus robur L., Carpinus betulus L., Fraxinus excelsior L., Acer campestre L., Acer pseudoplatanus L., Tilia cordata Mill., and Prunus avium L. Growth rates were monitored over a five-year period. Small transplants had the highest growth; they grew approximately 0.4 meters more than transplants from the other size categories. Our results show that the selection of the size of transplant has a significant impact on development and growth. However, differences in the post-transplant responses of individual species were found.

“…In practice, seeds could be collected from plants with I iv > 2, and then mixed species sowing based on relative abundance and plant-specific I iv in the community. Mixed vegetation species will respond better (in terms of survival/growth rates and high diversity) to different methods of planting, climatic factors, weed invasion, and water table depth [52,59]. Although CS among SF, SW, and NW was moderately similar, the dominated plant species were different, suggesting that restoration should combine CS and I iv to determine target plant composition.…”

“…The survey suggests that land will have lower soil water content and greater soil temperature compared with less degraded land so that short-term irrigation might be useful if it can be implemented to infiltrate at least 60 cm into the soil, because irrigation can increase long-term grass establishment and reduce erosion [23], and diffuse salinity. Although Szitár et al [69] found that altered soil conditions are unlikely to pose a major limitation to vegetation recovery and restoration measures do not need to bother with soil remediation, the high mean pH value (>8) may have affected plant survival [52] because it leads to a reduced availability of micronutrients that are important for plant growth [46]. On NF, trees (P. crassifolia) should be planted because forest plantations aiming at restoration could increase plant growth and carbon sequestration [70][71].…”

“…However, soil daily temperature will be greater on a degraded mountain due to lack of shade, so seedling establishment of P. crassifolia may be inhibited by soil temperature. In this case, artificial cultivation of P. crassifolia is needed to overcome critical seeding establishment and to increase survival rates [52,[72][73]. After the plants reach a certain height and are able to shade each other, they can be transplanted onto degraded land with a canopy density of about 48%.…”

“…Also, the relative abundance and density of species and interrelationships with changes in slope aspect should be measured because the restoration process is affected by both biotic and abiotic conditions, and the only production of a species list is inadequate and will likely be reflected in low species survival rates [50][51][52][53][54]. The objective of this work was to undertake and interpret a baseline survey of vegetation and soil properties in the Qilian Mountains to establish species composition and their relationship with abiotic factors.…”

Excessive human disturbance (e.g., overgrazing, deforestation) has degraded the environment in the Qilian Mountains in China. Vegetative restoration is likely to be a crucial tool to restore these biologically significant habitats, but it is impossible to achieve this goal if the baseline plant community composition and its variation with local environmental conditions were not understood fully. To assess plant community composition by slope aspect, four different aspects -south-facing slope (SF), southwest-facing slope (SW), northwest-facing slope (NW), and north-facing slope (NF) -were surveyed on three almost non-degraded mountains. The results showed that each slope aspect has different abiotic environments. From SF to NF, soil water content has an increasing trend, but it shows no difference between SF and SW; and daily soil temperature and pH have a decreasing trend, while the former shows no difference between SF and SW, and SW and NW; and the latter shows no difference between SW and NW; and soil organic carbon was significantly increased, but soil bulk density was significantly decreased. Herbaceous plants were dominant on SF, SW, and NW, and trees (Picea crassifolia) were dominant on NF. From SF to NW, the dominant herbaceous plants were Agropyron cristatum and Stipa grandis, Agropyron cristatum and Carex aridula, and Kobresia humilis and Carex crebra, respectively, while on NF they were Carex spp. and Polygonum macrophyllum. The baseline survey points to the need to consider underlying patterns in abiotic conditions when planning restoration programs in these degraded mountain habitats, and to select native plants similar to the original vegetation. The survey provides a vital milestone for the development of policy-based funding initiatives and for ongoing vegetation monitoring during restoration to assess if these vegetative targets have been met.

Effects of dams and geomorphic context on riparian forests of the Elwha River, Washington

et al. 2016

Abstract. Understanding how dams affect the shifting habitat mosaic of river bottomlands is key for protecting the many ecological functions and related goods and services that riparian forests provide and for informing approaches to riparian ecosystem restoration. We examined the downstream effects of two large dams on patterns of forest composition, structure, and dynamics within different geomorphic contexts and compared them to upstream reference conditions along the Elwha River, Washington, USA. Patterns of riparian vegetation in river segments downstream of the dams were driven largely by channel and bottomland geomorphic responses to a dramatically reduced sediment supply. The river segment upstream of both dams was the most geomorphically dynamic, whereas the segment between the dams was the least dynamic due to substantial channel armoring, and the segment downstream of both dams was intermediate due to some local sediment supply. These geomorphic differences were linked to altered characteristics of the shifting habitat mosaic, including older forest age structure and fewer young Populus balsamifera subsp. trichocarpa stands in the relatively static segment between the dams compared to more extensive early-successional forests (dominated by Alnus rubra and Salix spp.) and pioneer seedling recruitment upstream of the dams. Species composition of later-successional forest communities varied among river segments as well, with greater Pseudotsuga menziesii and Tsuga heterophylla abundance upstream of both dams, Acer spp. abundance between the dams, and P. balsamifera subsp. trichocarpa and Thuja plicata abundance below both dams. Riparian forest responses to the recent removal of the two dams on the Elwha River will depend largely on channel and geomorphic adjustments to the release, transport, and deposition of the large volume of sediment formerly stored in the reservoirs, together with changes in large wood dynamics.
