The use of uneven-aged silviculture has increased markedly in the past 20 years. This is especially true in the southern United States, where the use of clearcutting and planting is often viewed as a practice whose emphasis on fiber production results in unacceptable consequences for other values, such as those that benefit from maintenance of continuous forest cover over time. Public lands in ...

Structural changes over time in forests of shade-tolerant species are difficult to study because these stands are often broadly uneven-aged and not suitable for traditional chronosequence analysis. Yet because of past disturbances of variable intensity and frequency, there is often substantial structural variation among stands of a given site quality class. In this study, diameter distributions...

Mortality was recorded annually over a 15-year period after thinning in each of three evenaged stands (one ponderosa pine and two ponderosa pine/Douglas-fir/western larch), and after individual tree selection cutting in two uneven-aged ponderosa pine stands. Highest mortality occurred in the controls in both the evenand uneven-aged stands, primarily due to suppression, while weather was the lea...

Abstract For the first time, an economic analysis of a fully simulated forest transformation process from even-aged to uneven-aged stand structure using natural regeneration was performed individual tree growth simulator. A comparison ‘business as usual’ management approach (i.e. age-class scenario) also made. Norway spruce (Picea abies (L.) Karst.)-dominated forests different ages were selecte...

Upland hardwood stands on mesic, escarpment-oriented sites on the Cumberland Plateau region of northeastern Alabama provide a myriad management opportunities. Stands are primarily managed for Quercus, but the high species diversity allows for management that targets multiple species. Stand composition is unique in that dominant species include shade tolerant species such as Acer saccharum, inte...

Changing economics in the 20th century led to losses and fragmentation of semi-natural woodland Britain a reduction active management with many becoming increasingly neglected, even-aged closed canopy. Lack is known contribute declines some taxonomic groups, for example birds. However, response bats changes structure are poorly understood. We compared two measures bat activity, derived from sta...
