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 ... -
Der Einfluss von Stickstoff und Trockenheit auf die Vitalität einer Hainbuchen- und Kiefernverjüngung
(2019-05-29)Due to its physical properties Biochar has the potential of stabilizing a forest rejuvenation during periods of drought. To verify this, a field trial was set up in 2014 in the Hessian Ried. The observed mortality of the ... -
Drone-based assessments of crowns, canopy cover and land use types in and around an oil palm agroforestry experiment
(2019-04-11)Oil palm cultivation has vastly expanded in the last decades and led to high economic returns, but has also induced environmental problems including reduced biological diversity and impaired ecosystem services. One potential ... -
Process optimization of thermal modification of Chilean Eucalyptus nitens plantation wood
(2019-02-22)Eucalyptus nitens is one of the most important fast growing plantation species in Chile. Currently it is mostly used for pulp and paper, but in recent years there has been a growing market for solid wood products to increase ... -
Zu den gesundheitsfördernden Effekten von Waldaufenthalten
(2018-04-11)According to a forecast people of the high-income countries will suffer most on the two civilization diseases heart diseases and depression in year 2030. Currently, these diseases already lead to considerable financial ... -
Laubholz mit niedriger Umtriebszeit in Nordwestdeutschland - Charakterisierung der Vorkommen, Wachstumsmodellierung und waldbauliche Steuerung
(2018-03-02)The supply of short-lived deciduous trees (ALn) in Lower Saxony was analysed using data from the German national forest inventory (NFI, 2002 and 2012). The standard results of the NFI were augmented by own calculations, ... -
Wood anatomy and cytokinin-related responses in poplar (Populus sp.) under environmental stress
(2018-02-09)Woody plants like poplar are of great importance as a second generation bioenergy crop. However, wood formation is dynamic and strongly affected by exogenous factors such as drought or seasonality, and endogenous factors. ... -
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 ... -
Threatened tree species across conservation zones in a nature reserve of North-Western Vietnam
(2017-03-21)The high diversity of tree species in tropical forests is driven by a large proportion of rare species. Rare species are vulnerable and threatened to extirpation and extinction when their habitats are destroyed. This study ... -
Kohlenstoffspeicherung als Teilziel der strategischen Waldbauplanung
(2016-08-09)Carbon sequestration in forests is a highly topical issue in the current climate change debate. The most important carbon pools are living and dead tree biomass, timber products and their substitution effects. The carbon ... -
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 ... -
Nutrient response efficiency, tree-microbe competition for nutrients and tree neighborhood dynamics in a mixed-species temperate deciduous forest in central Germany
(2015-10-23)In most Central European countries, less than one percent of the remaining broadleaved forest is undisturbed and temperate forests face challenges such as species invasion, climate change and increased nitrogen deposition. ... -
Analyse von Schälschadensinventuren in Harz und Solling
(2015-06-18)The present work represents the continuation of a project that examined the causal relationships between environmental factors and the occurrence of bark stripping on spruce by red deer in the Harz and Solling mountains ... -
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 ... -
Modelle zur Abbildung asymmetrischer Kronenformen und zur Beschreibung der Zuwachsleistung für sechs Baumarten in Nordwestdeutschland
(2014-07-11)The canopy plays an important role in forest ecosystems: its structure, especially size and shape of the crowns and their position in relation to each other, determines the micro-climatic conditions at the forest floor, ... -
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 ... -
Tree water uptake partitioning and water use rates in a temperate mixed forest
(2014-01-09)Little information is available on the relationship between tree species diversity and forest stand water use although water availability is considered a major control of productivity in forests of central Europe and other ... -
New adaptive plot designs for sampling rare and clustered populations
(2012-02-07)In this methodological study, three new and more practical adaptive plot designs (I, II and III) are introduced with an overall objective to improve the efficiency of sampling rare and ...
