Abstract Uncertainty surrounding global change impacts on future forest conditions has motivated the development of silviculture strategies and frameworks focused enhancing potential adaptation to changing climate disturbance regimes. This includes applying current silvicultural practices, such as thinning mixed-species multicohort systems, novel experimental approaches, including deployment fu...
In order to support livelihoods, enhance food security, restore ecosystem services, and reduce pressure on forests, degraded land can be restored by utilising alternative land-use systems (ALUS), such as silviculture, silvipasture, hortipasture techniques. ALUS significantly modify the dynamics of soil nutrients in both surface subsurface layers. Soils from 0–15, 15–30, 30–45 cm layers Leucaena...
The twenty-first century has seen a shift in the philosophy and practice of forestry. Historic assumptions that prevailed as recently as three decades ago have been chalJenged in light of new-concepts and practices, developed through advances in research and lessons from practical experience. The goals of forcst management today encompass a wider array of resources than in the past, and manager...
Forest management in British Columbia requires that all resource values are considered along with a variety of appropriate management practices. For the past 100 years, partial-cutting practices were the method of choice when harvesting in Interior Douglas-fir (IDF) zone ecosystems. Along with a highly effective fire suppression program and minimal stand tending, these practices have created ne...
There is a growing demand for alternatives to Sweden's current dominant silvicultural system, driven by a desire to raise biomass production, meet environmental goals and mitigate climate change. However, moving towards diversified forest management that deviates from well established silvicultural practices carries many uncertainties and risks. Adaptive management is often suggested as an effe...

A general premise of forest managers is that modern silviculture should be based, in large part, on natural disturbance patterns and species' adaptations to these disturbances. An understanding of forest stand dynamics is therefore a prerequisite to sound forest management. This paper provides a brief overview of forest stand development, stand structures, and disturbance regimes and discusses ...
INTRODUCTION Oak-dominated forests of the Central and Eastern United States have generally not been regarded as suited to uneven-aged silviculture (Roach and Gingrich 1968, Sander and Clark 1971). In fact, several attempts to apply the selection method of reproduction cutting in oak-dominated stands have resulted in compositional shifts toward more shade tolerant species (Trimble 1970). Given t...
