Floodplain forests have become rare in Europe due to anthropogenic changes. A critical aspect of their restoration is re-introducing flooding via dike relocation, as implemented at the Elbe River near Lenzen/Germany. How forest development is influenced by dike relocation is still unclear and difficult to predict. Inside the dike relocation area at...

Die Diskussion über nicht einheimische Arten (Neobiota) und deren Management in Umwelt- und Naturschutz ist häufig geprägt durch eine prinzipielle Ablehnung des Fremden. Hieraus leitet sich nicht selten eine Bekämpfung der Arten im Biotopmanagement und in der Ökosystemrenaturierung ab. In diesem Kapitel soll diese Problematik beleuchtet werden und...

Plants are connected to habitats by functional traits which are filtered by environmental gradients. Since tree species composition in the forest canopy can influence ecosystem processes by changing resource availability, litter accumulation, and soil nutrient content, we hypothesised that non-native invasive trees can establish new environmental f...

With both a full collection of native vascular plant distributions and a full checklist of source plants of the Chinese Materia Medica (CMM), the Uygur Medicine (UM), and the Kazak Medicine (KM) for the Xinjiang region, we defined medicinal plant: vascular plant ratios (simplified as medicinal plant ratios hereafter) as the value of medicinal plant...

The workflow of data analyzing. (TIF)

The data of medicinal plant richness and ratios in Xinjiang, China. With the richness and ratio data of both full and randomly selected (by 5% of the full data) in the analyses. (XLSX)

The checklists of source plants of CMM, UM, and KM. Here, CMM is the list of species used in TCM that are distributed, both naturally and by cultivation, in Xinjiang; UM and KM are the full lists of species used in the two medical systems, whether if native to Xinjiang or from other regions.

Aim To determine biotic and abiotic controls on pine invasion globally within six ecoregions that include both introduced and native ranges. Locations: Río Negro province, Argentina; Aysén and Araucanía Regions, Chile; South Island (two ecoregions), New Zealand; Greater Yellowstone Ecosystem, USA. Methods We quantified tree abundance and size acr...

Species pool hypothesis is broadly known and frequently tested in various regions and vegetation types. However it has not been tested in the arid Xinjiang region of China due to lack of data. Here with systematic data from references and field survey, we comprehensively examined species pool hypothesis in this region. Took species richness in 0.1°...

The non-native trees Prunus serotina and Robinia pseudoacacia are the most frequent invasive species in the floodplain forests of the Biosphere Reserve Valle del Ticino located in the regions Lombardy and Piedmont. Due to their high competitiveness in comparison to the most frequent native trees Quercus robur, Carpinus betulus, and Ulmus minor, the...

Black cherry (Prunus serotina Ehrh.) is considered to be an invasive species in different European ecosystems, like open land habitats and woodlands. In the study area, the ‘Valle del Ticino’ biosphere reserve (northern Italy), the species has established, since it reproduces and spreads. Its ability to dominate the understory of forests hampers th...

Pot experiments, as a complement to field measurements, allow the investigation of plants under controlled conditions without distracting effects of heterogeneous environmental factors. Due to the longevity and larger dimensions of tree species, pot experiments with trees raise more problems than studies with herbaceous plants. We analysed 93 studi...

Context Identifying the traits of exotic species may explain their invasiveness and help control the negative impacts of these species on native ecosystems. In this study, we investigated root competition as an important driver for the competitiveness of two exotic tree species in the seedling stage. Aims In a pot experiment, carried out in Centra...

Soil seed banks are the ecological memory of plant communities and might represent their regeneration potential. This study examines the soil seed bank in hardwood floodplain forests of the biosphere reserve “Valle del Ticino” (Northern Italy) to find out whether the natural forest vegetation can potentially be restored by the soil seed bank. We co...

In hardwood floodplain forests of the North Italian Po Plain the non-native and light-demanding tree species Prunus serotina Ehrh. and Robinia pseudoacacia L. coexist with the native tree species Carpinus betulus L., Quercus robur L., and Ulmus minor Mill. In order to identify the factors controlling the establishment of seedlings of these species,...

Aims Invasive species continue to be a worldwide threat to ecosystems mainly as a cause for biodiversity loss. Forest ecosystems, for example, are subject to a change in species composition due to the invasion of exotic species. Specifying the attributes that cause the strong competitiveness of several exotic species may improve the ability to unde...

We assessed the effectiveness of different management strategies against the non-native invasive tree species black cherry (Prunus serotina Ehrh.). The species causes substantial management problems in European forest ecosystems, like the Valle del Ticino Biosphere Reserve in Italy, by suppressing the regeneration of native tree species. This can m...

As one cause for biodiversity loss, invasive alien species are a worldwide threat. In forests, however, invasive tree species can also have an enormous biomass potential which can be harvested while taking measures against the species. Allometric equations help estimating the biomass but are often only available for the native range of the species....
