The forests of North Mongolia are largely dominated either by larch (Larix sibirica Ledeb.) or birch (Betula platyphylla Sukaczev). The increasing demand for timber and firewood is currently met by removal of wood from these forest stands. Therefore, silvicultural approaches that account for both utilization and protection are needed. Thinning trials were established in the research area Altans...

Most of us, scientists and laymen alike, are deeply fascinated by old-growth forest. We travel to places like the Tongass National Forest in Alaska or the Biatowieža National Park in Poland to enjoy the sight of forests left to their own devices, with their majestic trees, intriguing structure and rare wildlife. For us, the fascination arises from a mixture of interest, aesthetic pleasure and m...

We analysed climate change impacts on the growth and natural mortality of forest tree species and forest carbon (C) balance along an elevation gradient extending from the Pannonian lowland to the West Carpathian Mountains (Central Europe). Norway spruce Picea abies, European beech Fagus sylvatica, and oak Quercus sp. were investigated for 2 future time periods: 2021–2050 and 2071–2100. The peri...

Forest structure at stand level plays a key role for sustainable forest management, since the biodiversity, productivity, growth and stability of the forest can be positively influenced by managing its structural diversity. In contrast to field-based measurements, remote sensing techniques offer a cost-efficient opportunity to collect area-wide information about forest stand structure with high...

Temperate and boreal forests of the Northern Hemisphere have recently been identified as important carbon sinks. Accurate calculation of forest carbon budget and appraisal of the temporal variations of forest net carbon fluxes are important topics to elucidate the ‘‘missing sink’’ question and to follow up the changing carbon dynamics in forests. In this article, recent carbon budgets of the fo...
