Acquisition and Characterization of Canopy Gap Patterns of Beech Forests

Nuske, Robert S. (2019-11-22)

Canopy gap research in European beech-dominated forests has experienced a remarkable upswing in the last decades. It contributes to answering both fundamental ecological questions and to designing silvicultural interventions ...

Analyse und praktische Umsetzung unterschiedlicher Methoden des <i>Randomized Branch Sampling</i>

Cancino Cancino, Jorge Orlando (2003-07-15)

Randomized Branch Sampling (RBS) is a multistage sampling procedure, which uses the natural branching of a tree in order to take samples for estimating one or several characteristics of the ...

Approaches for the optimisation of double sampling for stratification in repeated forest inventories

von Lüpke, Nikolas (2013-06-17)

Double sampling for stratification is an efficient sampling scheme that could prove its practicability in different forest inventories. Nevertheless, further increases of efficiency are desired. Several approaches for ...

Bedingte und unbedingte Fehler bei geostatistischen Vorhersagen - forstwissenschaftliche Fallstudien

Cullmann, Andreas Dominik (2007-04-20)

In most geostatistical applications the stated mean squared prediction error is unconditional with respect to the data since the conditional marginal distribution and with it the conditional error is only known for the ...

Composite Estimation of Stand Tables

Bierer, Daniel (2008-09-22)

One of the most important parameters for characterizing a forest stand is its stand table. In this thesis, the problem of estimating stand tables in stands with only a few sample plots (i.e. ...

Development of efficient forest inventory techniques for forest resource assessment in South Korea

Yim, Jong-Su (2009-02-26)

A new National Forest Inventory (NFI) program in South Korea has been implemented to provide reliable forest resource information for forest policy decision-making and monitoring at the ...

Ecological Management of Tropical forests: Implications for climate change and Carbon Fluxes

Djomo Njepang, Adrien (2010-12-20)

Tropical deforestation and forest degradation contributes to more than 20% of the global greenhouse gases emitted. Deforestation and its impacts can be more easily estimated with satellite ...

Fernerkundliche Waldflächenerfassung im Kontext internationaler Umweltabkommen

Magdon, Paul (2013-09-23)

In reaction to the ongoing anthropogenetic changes of the earth' ecosystems the United Nations Conference on Environment and Development was hold in 1992 in Rio de Janeiro. This conference was an important starting point ...

Forstplanung auf der Basis von Eingriffsinventuren

Staupendahl, Kai (2007-11-20)

This dissertation presents the general concept and specific application details of a permanent forest inventory in which the forest stand is the reference unit for resource assessment and planning. The stand-oriented ...

Growth and Site Conditions of Acacia mangium, Acacia hybrid, Eucalyptus urophylla, Cinnamomum parthenoxylon and Erythropholeum fordii for Livelihood Security of Smallholders in Industrial Tree Planting Programs of Vietnam

Sein, Chaw (2012-03-16)

This research has been carried out in the context of a CIFOR (Center for International Forestry Research) project. The purpose of the project is to strengthen rural institutions and promote ...

Ein klimasensitives, autoregressives Modell zur Beschreibung der Einzelbaum Mortalität

Schoneberg, Sebastian (2017-11-29)

Forestry encounters new challenges in the face of the climate change, that require adaption measures of current forest management practices. Some positive but mostly negative effects due to the climate change are anticipated ...

Laubholz mit niedriger Umtriebszeit in Nordwestdeutschland - Charakterisierung der Vorkommen, Wachstumsmodellierung und waldbauliche Steuerung

Fischer, Christoph (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, ...

Methodische Ansätze zur Erfassung von Waldbäumen mittels digitaler Luftbildauswertung

Fuchs, Hans-Jörg (2004-02-16)

Since 1994 the European Environmental Monitoring has been complemented by a program of intensive surveys of forest ecosystems (Level 2). Major goal of the Intensive Monitoring Program is ...

Modelle zur Abbildung asymmetrischer Kronenformen und zur Beschreibung der Zuwachsleistung für sechs Baumarten in Nordwestdeutschland

Sprauer, Susanne (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, ...
