“…The similarities in the densities of regenerating trees in disturbed and undisturbed habitats one year after logging indicates that post-logging recruitment is rapid, as previously reported (e.g., Duah-Gyamfi et al, 2014;Rockwell et al, 2014;Soriano et al, 2012;Karsten et al, 2014;Mostacedo et al, 2009;Toledo-Aceves et al, 2009;Magnusson et al, 1999). Regeneration was particularly abundant on the exposed mineral soil of log landings, secondary roads and skid trail (Fredericksen and Pariona, 2002).…”

“…These other E. cyclocarpum populations suffered catastrophic losses, much worse than in the Plan Costa managed forest. The success of regenerating most commercial species while keeping their volume stocking at reasonable levels and the site fully occupied by timber producing trees were accomplishments for Plan Costa that compare favorably with results in other tropical silviculture cases reported, such as those in Putz et al [25], and Duah-Gyamfi et al [26]. In 2003, Cruz del Tuito halted logging operations while a new administration implemented improved accounting procedures to correct clerical irregularities in the procurement chain; however, latter activities picked up the slack, so by 2010 all volume sold was already harvested and delivered to the final user.…”

Current Mexican forest management is the product of a history that dates back to 1926. Earlier approaches were directly or indirectly aimed at attaining the normal forest model. Around 1980, multi-resource and environmental impact considerations were mandated for all private timber operations. Timber-oriented silviculture was deemed insufficient to take proper care of non-timber values in the forest. Concerns about water quality, biodiversity, and natural conservation were the motives for promoting voluntary best OPEN ACCESSForests 2015, 6 671 management practices, in 2012 and afterwards. In this research, two traditional Mexican forest management schemes, Sicodesi and Plan Costa, enhanced with best management practices, are compared to Mapa, a management method specifically designed to manage landscape attributes. Results from two successive forest inventories 10 and 13 years apart show that Sicodesi and Plan Costa, even when modified to comply with best management practices, failed to maintain proper stewardship of non-timber values. Mapa, however, employed multiple means to drive forest dynamics to fulfill multi-resource objectives, constrained by self-financing and competitive profitability. These capabilities in Mapa enabled some degree of control over non-timber values, but many more important processes occur beyond the property boundary, and beyond the planning scope considered in Mapa and all other forest planning methods.

“…However, timber species seedling and sapling richness and abundance are usually higher on the skid trail than in the forest understorey (Swaine & Agyeman ), mainly due to the presence of pioneer species, which are scarce in unlogged areas (Swaine & Agyeman ; Duah‐Gyamfi et al. ). Our results also suggest that native species plantations may be important in facilitating natural regeneration in degraded forest conditions.…”

Abbreviations F = Farmland; FU = Forest understorey; LGB = Large canopy gaps dominated by Broussonetia papyrifera; LGC = Large canopy gaps dominated by Chromolaena odorata; LR = Logging road; MAP = Mansonia altissima plantation; MDT = Modified Taungya System; NDP = Nauclea diderrichii plantation; NPLD = Non-pioneer light-demander; P = Pioneer; SB = Shade-bearer; ST = Skid trail; TIP = Terminalia ivorensis plantation. Abstract Question: Does the invasive tree species Broussonetia papyrifera facilitate the natural regeneration of native tree species in a degraded tropical forest landscape? Location: Afram Headwaters Forest Reserve, southern Ghana.Methods: We established sampling areas and assessed seedlings and saplings <5 cm DBH in nine habitats. The habitats were logging road, skid trail, large canopy gaps dominated by B. papyrifera, large canopy gaps dominated by invasive Chromolaena odorata, Nauclea diderrichii plantation, Mansonia altissima plantation, Terminalia ivorensis plantation, abandoned farmland and unlogged forest.Results: We found that the abundance of pioneers declined with increasing abundance of B. papyrifera. This trend was more pronounced in the farmland and in the N. diderrichii plantation. By contrast, increased abundance of B. papyrifera did not lead to a decrease in the abundance of the shade-tolerant species. B. papyrifera seedlings and saplings were absent in the forest understorey. We also found a lower abundance and richness of some vulnerable tree species and valuable timber species in the N. diderrichii plantation and in gaps dominated by B. papyrifera. However, we recorded both shade-tolerant and shade-intolerant species in the gaps dominated by B. papyrifera. Conclusions:We found both shade-tolerant and shade-intolerant species in the B. papyrifera-dominated gaps. This can provide a basis for future studies to explore the potential of such tree species in restoration programmes targeted at B. papyrifera-invaded sites. Our results also suggest that the integrity of the undisturbed forest patches in the landscape must be protected to help prevent B. papyrifera from spreading further. We suggest further studies should be conducted at replicated sites with a similar habitat that represent varying levels of invasion by B. papyrifera to draw conclusions regarding the species' potential to facilitate regeneration of native tree species.
