AbstractThe positive ecological interaction between gap formation and natural regeneration has been examined but little research has been carried out on the effects of gaps on natural regeneration in forests under different intensities of disturbance. This study evaluates the composition, diversity, regeneration density and abundance of natural regeneration of tree species in gaps in undisturbed, intermittently disturbed, and disturbed forest sites. Bia Tano Forest Reserve in Ghana was the study area and three gaps each were selected in the three forest site categories. Ten circular subsampling areas of 1 m2 were delineated at 2 m spacing along north, south, east, and west transects within individual gaps. Data on natural regeneration < 350 cm height were gathered. The results show that the intensity of disturbance was disproportional to gap size. Species diversity differed significantly between undisturbed and disturbed sites and, also between intermittently disturbed and disturbed sites for Simpson’s (1-D), Equitability (J), and Berger–Parker (B–P) indices. However, there was no significant difference among forest sites for Shannon diversity (H) and Margalef richness (MI) indices. Tree species composition on the sites differed. Regeneration density on the disturbed site was significantly higher than on the two other sites. Greater abundance and density of shade-dependent species on all sites identified them as opportunistic replacements of gap-dependent pioneers. Pioneer species giving way to shade tolerant species is a natural process, thus make them worst variant in gap regeneration.

In early 2005, 10,045 ha Community Forests (CFs) were certified in Bajhang and Dolakha districts of Nepal by using the Forest Stewardship Council (FSC) certification scheme. After two years of forest certification, subsequent questions are being asked such as: What benefits have certification brought for the Forest Users Groups (FUGs)? What tangible differences are there in forest management system because of forest certification? and What lessons have been learnt from the certified forests? In an attempt to answer these questions, a study was carried out in April 2007 in Dolakha district where 11 (2,182 ha) community managed forests were certified in 2005. On the basis of field study from two certified forests (Vitteripakha and Suspa) of the district, this paper analyzes the effects of forest certification and its implications for enhancing Sustainable Community Forestry (SCF) in Nepal. Key words: Sustainable forest management, forest certification, community forestry Banko Janakari: A journal of forestry information for Nepal Vol.17(1) 2007 pp.11-16

Operational plans are a key element in community forestry in Nepal. However, the relevance of these plans to forest user groups (FUGs) is under scrutiny. This study investigates the usefulness of operational plans against the backdrop of knowledge, capacity and management practices of FUGs. Data were collected from 13 operational plans, 16 group discussions involving forestry professionals, and 218 household interviews in two villages of Lamjung district in Nepal. Whereas operational plans should specifically reflect site specific objectives and activities of forest management, the survey revealed identical objectives across the community forests. Current operational plans are technically complex, poorly linked to the place-based context of livelihood needs and less useful to the FUGs to inform and enhance forest management. This study proposes to differentiate community forests according to their production potentials, and revise the operational plans by shortening the elements that have little or no relevance to the FUGs.

In June 1997, we visited the Magnifica Comunità di Fiemme (MCF), a community forest in the Alps of northern Italy. We have prepared this article to help broaden the perspectives of Forestry Chronicle readers on community forests and what they mean in various parts of the world. We first describe the area and its forests, and then give a brief history of the MCF. Then we review the forest-management strategies used in this Norway spruce forest, and summarize the logging and wood-processing activities of the enterprise. We continue with a comparison of this community forest with three community forests in Canada, concluding that generalization on what makes a community forest successful is dangerous — each situation is unique. Finally, given that the MCF recently won permission to use the eco-label of the Forest Stewardship Council (FSC), we discuss our perceptions of how the MCF operation does and does not meet the FSC's Principles and Criteria of Forest Stewardship. Despite several shortcomings, we believe that the MCF is in most respects a sound example of sustainable forest management.

Abstract Private and public technical assistance foresters were surveyed in 12 southern states. Their management practices on southern forests are summarized by employment sector. Industrial foresters helped manage more acres per forester than consultants or state foresters. All foresters assisted more in planting trees than in preparing for natural regeneration. Industrial foresters favored clearcutting, consultants selective cuts, and state foresters a mix. Consultants performed much more natural regeneration than industrial or state foresters, who focused almost exclusively on artificial regeneration. Respondents also provided written opinion about current forest management and environmental issues, as well as suggestions for professional education. South. J. App. For. 14(1):44-48.

Abstract All timberland investment management organizations (TIMOs) and industrial landowners in Mississippi were surveyed during 1998 and 1999 to determine their annual forest management practices and related expenditures. The response rate was 65%, and respondents accounted for approximately 90% of the timberland owned by these two landowner groups. For analysis purposes, industrial landowners were separated into two categories: large (>10,000 ac) and small (<10,000 ac). Pine plantations represented 66% of TIMOs' timberland base compared to 55% for large industrial landowners and less than 50% for small industrial landowners. Over the 2 yr study period, TIMOs and large industrial landowners invested heavily in site preparation and planting as well as midrotation chemical release and fertilization. In contrast, small industrial landowners relied on natural regeneration to a much greater extent and conducted few, if any, midrotation treatments. As a group, TIMOs and industrial landowners spent approximately $20/ac annually on their Mississippi timberlands. Overhead represented slightly over 40% of this total, with silvicultural treatments accounting for the remainder. Property taxes represented the largest overhead expense. In total, these landowners spent $67 million in 1998 and $54 million in 1999 to maintain and manage their Mississippi timberlands. South. J. Appl. For. 27(2):83–91.

Rotational logging practices are used with the goal of reducing forest disturbance impacts on biodiversity. However, it is poorly understood whether such forest management practices conserve the demographic and genetic composition of animal populations across logged landscapes. Here we investigated whether rotational logging practices alter patterns of landscape-scale population abundance and genetic diversity of a forest-dwelling lizard (Eulamprus heatwolei) in south-eastern Australia. We sampled lizards (n = 407) at up to 48 sites across a chronosequence of logging disturbance intervals (<10 to >60 years after logging) to assess site-specific population changes and genetic diversity parameters. Lizard abundances exhibited a significant curvilinear response to time since logging, with decreased numbers following logging (<10 years), increased abundance as the forest regenerated (10–20 years), before decreasing again in older regenerated forest sites (>30 years). Lizard genetic diversity parameters were not significantly influenced by logging disturbance. These results suggest that logging practices, whilst inducing short-term changes to population abundance, had no measurable effects on the landscape-scale genetic diversity of E. heatwolei. These results are important as they demonstrate the value of monitoring for evaluating forest management efficacy, and the use of different population-level markers to make stronger inference about the potential impacts of logging activities.
