Restoration of coniferous monocultures towards mixed broad-leaved forests in Central Europe – Patterns and processes of stand and vegetation diversification
(2024-11-05)Globally, forests provide essential ecosystem services to society, but their functionality is increasingly impaired by abiotic and biotic disturbances that are expected to further increase with predicted climate change. ... -
Spatial and temporal fine root distribution growth of European beech, Norway spruce, and Douglas-fir in pure and mixed stands with beech under different site conditions
(2024-08-15)The major challenge of forest management globally is to manage forests in such a way that aspects of wood production and forest conservation are combined in order to have pro-ductive and stable forests that continuously ... -
Auswirkung von Bodenbearbeitungen auf den Nährstoffhaushalt von Waldböden sowie den Erfolg von Eichenkulturen
(2024-04-05)Site preparation in forests has received criticism for potentially reducing site produc-tivity due to soil compaction and nutrient losses. Nontheless, from a practical perspec-tive, site preparation is an essential factor ... -
From Points to Forests - The potential of 3D point clouds to evaluate the structural complexity of differently managed beech forests
(2024-03-04)Climate change is leading to global shifts that can create a particular challenge for the stability and vitality of forest ecosystems. In the temperate forests of Central Europe, the natural forest vegetation is dominated ... -
Quantifying three-dimensional stand structure of European beech forests along a management gradient
(2022-04-26)Forest structure is of functional importance for ecosystem stability and resilience, as well as for numerous other ecosystem functions and services. In this context, a high structural complexity can have a positive effect ... -
Influence of intra- and interspecific competition on timber quality of European beech
(2021-01-21)The timber quality of a single tree is considerably influenced by interactions with other individual trees. These competitive effects from neighbouring trees may be regulated through silvicultural treatments. Consequently, ... -
Quantifying the impact of forest management intensity and tree species diversity on individual tree shape and three-dimensional stand structure
(2020-11-04)The three-dimensional distribution of trees and their crowns is an essential characteristic of forest ecosystems that is directly related to several ecosystem functions and services. Silvicultural interventions modify the ... -
Quantifying stand structure and structural complexity along a management gradient in temperate forests
(2020-10-01)The structure and structural complexity of forests influence many important characteristics of forest ecosystems, as well as their functions and services, such as ecosystem stability, maintenance of biodiversity and carbon ... -
Zuwachspotenziale und Klimasensitivität eingeführter Baumarten in Nordrhein-Westfalen
(2020-02-14)The ongoing global change with increasing mean annual temperatures, altered conditions in precipitation and a higher expected frequency and magnitude of extreme weather events leads to unpredictable environmental conditions ... -
The effect of neighborhood identity on seasonal tree growth responses and ecophysiological characteristics of European beech (Fagus sylvatica L.)
(2020-01-17)Climate change related rise in mean surface (air) temperature, altered intra-annual thermal and precipitation regimes as well as an expected increase of extreme weather events which are also prognosticated for large parts ... -
Etablierung von Nothofagus obliqua, Nothofagus glauca und Quillaja saponaria in der mediterranen Zone Chiles
(2019-10-30)Within the framework of the overall research project "Tree diversity in Mediterranean forests in Chile: are close-to-nature forestry and profitability mutually exclusive?" a field experiment with three Chilean tree species ... -
Evaluation of the Efficacy of Wildlife Warning Reflectors to Mitigate Wildlife-Vehicle Collisions on Roads
(2018-12-04)Summary Wildlife-vehicle collisions cause human fatalities as well as economic and ecological losses on roads worldwide. Multiple mitigation measures have been developed over the past decades, while wildlife warning ... -
Quantifying three-dimensional stand structure and its relationship with forest management and microclimate in temperate forest ecosystems
(2018-02-01)Summary Forest management modifies the spatial structure of forest ecosystems, which is considered to be relevant for habitat availability and biodiversity as well as several ecosystem processes and functions. Contrary ... -
Reaktion von Waldbeständen am Rande der südlichen Taiga auf Klimafaktoren, natürliche und waldbauliche Störungen
(2017-11-30)The northern Mongolian mountain forest steppe, the transition zone between taiga and open steppe, is rich in plant and animal life. It is the most productive region in the country in terms of agriculture and, as a result, ... -
Picea abies and climate change – does increasing thinning intensity prevent drought stress?
(2017-10-11)The predicted increase in frequency of intense and prolonged drought events challenges forest management. Centuries of forest management has led to Norway spruce (Picea abies [L.] Karst.) monocultures outside its natural ... -
Natürliche Waldentwicklung unter dem Einfluss des Borkenkäfers im Nationalpark Berchtesgaden
(2016-06-24)Disturbances are an integral part of forest ecosystems. Integrating single-tree dynamics to large-scale disturbances as windthrows, fire or insect calamities, disturbances influence natural species composition and regeneration ... -
Quantifizierung der Feinwurzeln von Bäumen durch elektrische Verfahren
(2015-04-23)The quantification especially of fine roots of trees creates some difficulty because, contrary to the aboveground parts of the tree, roots are not readily visible. In recent years electrical methods have been developed for ... -
Competition mechanisms of native and exotic tree species
(2014-01-09)The amount of exotic plant species introduced to new regions by humans has considerably increased in the last two centuries. Worldwide, the invasion of exotic species represents an important threat to native biodiversity ...
