Tree regeneration was compared among closed-canopy sites and 4±11-year old natural and felling gaps in a selectively logged semideciduous tropical forest in southeastern Mexico. Closed-canopy sites and gaps were selected strati®ed randomly. In addition, all large natural and felling gaps encountered were sampled. All stems 5 cm dbh were sampled in sets of 10 m plots in closed-canopy sites and g...

As part of the multidisciplinary National Fire and Fire Surrogate Study, we used drift fences with pitfall traps to determine how three fuel reduction treatments affected ground-dwelling macroarthropods in the southern Appalachian Mountains of North Carolina. Four experimental units, each 14 ha, were contained within each of three replicate blocks. Treatments were (1) prescribed burning, (2) me...

Industrial logging has become the most extensive land use in Central Africa, with more than 600,000 square kilometers (30%) of forest currently under concession. With use of a time series of satellite imagery for the period from 1976 to 2003, we measured 51,916 kilometers of new logging roads. The density of roads across the forested region was 0.03 kilometer per square kilometer, but areas of ...

Preharvest herbicide treatment of undesirable and unmerchantable v getation was compared to postharvest felling. Ten years after the clearcut harvesting, the preharvest treatment had increased the number and proportion of desirable stems and decreased the number and proportion of undesirable sprouts in the dominant stand. Stands that developed after the preharvest herb•cide treatment are domina...

An invasive shrub, Chinese privet (Ligustrum sinense Lour.), was removed from heavily infested riparian forests in the Georgia Piedmont in 2005 by mulching machine or chainsaw felling. Subsequent herbicide treatment eliminated almost all privet by 2007. Recovery of plant communities, return of Chinese privet, and canopy tree growth were measured on removal plots and heavily invaded control plot...

Sustainable natural forest management initiatives in the lowland tropical forests of Bolivia require that cost-effective measures be identified to help maintain timber stand quality and reduce damage to advance regeneration during logging operations. This study considered the potential costs and benefits of including two ‘best’ management practices the pre harvest flagging of future crop trees ...

Questions: Are calorimeters and pyrometers accurate and reliable for describing fire parameters in large-scale ecological projects, and can data from them predict data derived from thermocouples? Do mechanical pre-treatments in Florida scrub areas alter fire properties? Location: Lake Wales Ridge, Florida, USA. Methods: We deployed thermocouples attached to digital dataloggers, copper and lacqu...

Background: The traditional approach to limiting impacts of forestry on biodiversity is to set aside forest areas of particular conservation interest, either as formally protected reserves or on a voluntary basis. Many set-asides are left more or less untouched, but some of them have a history of disturbances such as wildfires, forest grazing, coppicing or small-scale felling. Such areas may gr...

An efficient wood harvesting activity aims to fully recover wood as a measure to increase the profit, but safety prescriptions should be obeyed each time when harvesting operations are performed. A study was carried out in three forest compartments in order to determine whether the actual tree felling procedures match the recommended ones and, if not, to compare how the used practices may affec...
