Recent Increase

Natural regeneration will continue to play an important role in forest management practices in British Columbia despite the recent increase in artificial regeneration. It is anticipated that by the time the artificial regeneration programme has been fully developed, up to fifty per cent of the areas logged will be restocked artificially, leaving the other fifty per cent to restock naturally.

Depth Interviews

Local wisdom is very influential in forest conservation, for indigenous forest communities to have sustainable functions either from the environmental or ecological, economic and socio-cultural fields. The objectives of this study were to: (1) analyze the nagari forest management practices, (2) Analyze the values and practices of local wisdom on the management of nagari forests, (3) analyze the sustainability of nagari forests, (4) to analyze the relation of nagari forest management practices to the sustainability of forests nagari. Research methods used to explore facts, data, and information in this study used a quantitative approach with a questionnaire supported by in-depth interviews and observation. The results of this study indicate that there is a unidirectional relationship between the indicators of the characteristics of the Nagari forest and the sustainability of the Nagari forest consisting of ecological, socio-cultural and economic sustainability. On the other hand, the management practices of nagari forests are linked to the sustainability of nagari forests but not significant. Keywords: Forest sustainability, Local wisdom ABSTRAK Kearifan lokal sangat berpengaruh didalam pelestarian hutan, bagi masyarakat adat hutan memiliki fungsi yang berkelanjutan baik itu dari bidang lingkungan atau ekologi, ekonomi dan sosial-budaya.

Water Holding

AbstractForest management practices play an important role in regulating the soil water-holding capacity of plantation. However, most studies focus on soil water dynamics present during large-scale forest loss and afforestation events, while little is known about how soil water under different forest management practices responds to rainfall events and which factors mainly regulate soil water-holding capacity. In this study, a stable hydrogen isotope was used to explore the contribution of three natural rainfall events (8.9, 13.3 and 67.7 mm) to soil water (CRSW) in a Pinus massoniana plantation under four forest management practices (no thinning (NTN), understory removal (USR), light-intensity thinning (LIT) and heavy-intensity thinning (HIT)) in the Three Gorges Reservoir Area of the Yangtze River Basin in China. Furthermore, a structural equation model was employed to determine the effects of vegetation biomass and soil properties on the CRSW. The results showed that plantation soil under different forest management practices exhibited different water-holding capacities. Following light (8.9 mm) and moderate (13.3 mm) rainfall events, the CRSW in the HIT stand was slightly higher than that in the other stands. Following heavy (66.7 mm) rainfall event, the CRSW of most layers in USR stand was not different from the other three stands, while the CRSW in the LIT and NTN stands was significantly higher than that in the HIT stand in the 0–100 cm soil layers, suggesting that soil in the LIT and NTN stands had a greater water-holding capacity than that in the HIT stand. In addition, soil properties were the main factors directly affecting the CRSW, explaining 60% and 37% of the variation in the CRSW on the first and seventh days after heavy rainfall, respectively. Overall, compared to the HIT stand, the LIT and NTN stands showed greater capacity in retaining rainwater. Therefore, under expected global changes with frequent occurrences of extreme precipitation events, methods involving light-intensity and no thinning should be employed to build up soil and water conservation functions, which will be critical for keeping water-holding capacity and moderating floods.

Age Category

This study aimed to estimate biomass and organic carbon in stands of Pinus taeda L. at different ages (14, 16, 19, 21, 22, 23 and 32 years) and located in the municipality of General Carneiro (PR). In order to estimate biomass and organic carbon in different tree components (needles, live branches, dead branches, bark and stem wood), the destructive quantification method was used in which seven trees from each age category were randomly sampled across the stand. Stocks of biomass and organic carbon were found to vary between the different age categories, mainly as a result of existing dissimilarities between ages in association with forest management practices such as thinning, pruning and tree density per hectare.

Historical Forest

Tree-ring widths (TRW) of historical and archeological wood provide crucial proxies, frequently used for high-resolution multi-millennial paleoclimate reconstructions. Former growing conditions of the utilized trees, however, are largely unknown. Potential influences of historical forest management practices on climatic information, derived from TRW variability need to be considered but have not been assessed so far. Here, we examined the suitability of TRW series from traditionally managed oak forests (Quercus spp.) for climate reconstructions. We compared the climate signal in TRW chronologies of trees originating from high forests and coppice-with-standards (CWS) forests, a silvicultural management practice widely used in Europe for most of the common era. We expected a less distinct climate control in CWS due to management-induced growth patterns, yet an improved climate-growth relationship with TRW data from conventionally managed high forests. CWS tree rings showed considerably weaker correlations with hydroclimatic variables than non-CWS trees. The greatest potential for hydroclimate reconstructions was found for a large dataset containing both CWS and non-CWS trees, randomly collected from lumber yards, resembling the randomness in sources of historical material. Our results imply that growth patterns induced by management interventions can dampen climate signals in TRW chronologies. However, their impact can be minimized in well replicated, randomly sampled regional chronologies.

Nonindustrial Private Forest

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.
