Mixed commercial plantation forests often receive little or no attention in terms of conservation of protected habitats and species. This study was aimed at assessing the value of such habitats for bats. In July 2015 we used standardised mist netting in 11 locations within and near the Natura 2000 sites “Nietoperek” and “Buczyny Łagowsko-Sulęcińskie” in western Poland. Particular attention was paid to mixed plantation forest, usually dominated by Scots pine (Pinus sylvestris). Natural and protected habitats, i.e. riparian woodlands and beech forest were also investigated for comparison. In total 96 bats of 12 species were caught. The highest number of bats (15.0 individuals caught per night) and the highest biodiversity index (H´) was recorded in localities situated in mixed plantation forest. Contrary to common evaluation of this type of habitat, mixed plantation forest may serve important role for local bat populations by providing commuting corridors and possibly also foraging areas.

Conversion of natural broad-leafed evergreen forests into pure and mixed plantation forests in a subtropical area in China is a common practice in forest management. We investigated the effects of this conversion on litterfall, litter decomposition, and nutrient cycling. Monthly deposition of total N, P, K, Ca, and Mg through throughfall, stemflow, and various components of litterfall was investigated and compared over 3 consecutive years from January 1989 to December 1991 for both forests. The total annual fine litterfall over 3 years of observation was 4.8 t/ha in a pure plantation conifer forest of Chinese-fir (Cunninghamia lanceolata), 7.1 t/ha in a mixed plantation forest of Chinese-fir and Schima superba, and 13.3 t/ha in a natural broad-leafed evergreen forest of Castanopsis kawakamii, respectively. The contributions of litterfall to the total nutrient fluxes were greater than those of throughfall and stemflow for all five nutrient elements in two contrasting forests of Chinese-fir and C. kawakamii. The results of this study demonstrate that natural broad-leafed evergreen forest has a greater capability of nutrient return, coupled with higher rates of litter decomposition and nutrient release, larger soil nutrient pools, and higher nutrient availability, than pure forest, suggesting that conservation of a natural forest is a necessary measure for maintaining woodland soil quality and primary productivity.

Vietnam’s forests have experienced a notable transformation over the past 20 years from net deforestation to reforestation and expanding forests. Continued reforestation that aims to achieve further economic and environmental benefits remains a national priority and strategy. We explore the current status of plantation forests and highlight possible means to facilitate their expansion in the uplands of Vietnam. We employ mixed method triangulation to empirically explore plantation forests and their economic role in household livelihood, to quantify trade-offs between plantation forests and shifting cultivation, and to assess the constraints on plantation forest expansion in Nghe An province, north-central Vietnam. Results show that forest in the study area expanded by 406,000 ha (71.1%) between 1990 and 2016. Plantation forests increased by nearly 500% (from 32,000 ha to 190,000 ha), while natural forests expanded by 48.1% (from 538,000 ha to 797,000 ha). Plantation forests contributed an average of 35.1 percent of total household income in wealthier households and 27.9 percent of income in poor households. Switching from shifting cultivation to plantation forests would increase total household income and average carbon stock but decrease food provision. Total Economic Value would be higher for plantation forest scenarios if increased carbon stocks in plantations can be monetized. This carbon income might drive conversion of shifting cultivation to plantation forests. Constraints on further expansion of plantation forest are low external cooperation, education, market stability, and agroforestry extension services. Our empirical results inform national plantation forest development, sustainable upland livelihood development, and climate change mitigation programs to ultimately facilitate forest transition and improve the resilience and sustainability of socio-ecological systems.

Few studies have explored how human land uses influence and support persistence of forest biodiversity in central Kenya. In the case of the Mount Kenya ecosystem, farmlands and plantation forests are significant land-use types. Using point counts, we assessed bird communities in natural forests, plantation forests, and farmlands in the Nanyuki Forest Block, Western Mount Kenya. Bird point counts were undertaken during two sampling periods (wet and dry season). Compared to farmlands and plantation forest, natural forest had the highest overall avian species richness and relative species richness of all except one forest-dependent foraging guild (granivores) and nonforest species, which occurred frequently only on farmlands. Plantation forest had the lowest relative richness of all avian habitat and foraging guilds. Conversely, specialist forest-dependent species mainly occurred in the structurally complex remnant natural forest. Our study underscores the importance of remnant natural forests for the persistence and conservation of forest biodiversity and risks posed by replacing them with plantation forests and farmlands.

Abstract The risk of extreme events due to weather and climate change, such as winds of unprecedented magnitude, is predicted to increase throughout this century. Artificial ecosystems, such as coniferous plantation forests, can suffer irreversible deterioration due to even a slight change in environmental conditions. However, few studies have examined the effects of converting natural forests to plantations on their vulnerability to catastrophic winds. By modelling the 2004 windthrow event of Typhoon Songda in northern Japan using the random forest machine learning method, we answered two questions: do Abies plantation forests and natural mixed forests differ in their vulnerability to strong winds and how do winds, topography and forest structure affect their vulnerability. Our results show that Abies plantation forests are more vulnerable to catastrophic wind than natural mixed forests under most conditions. However, the windthrow process was common to both types of forests, and the behaviour of wind inside the forests may determine the windthrow probability. Future management options for adapting to climate change were proposed based on these findings, including modifications of plantation forest structure to reduce windthrow risk and reconversion of plantations to natural forests.

Abstract Currently, community plantation forests play an essential role in providing wood supply for the timber industry with due regard to sustainability. One way to achieve the sustainability aspects of forest management is by conducting monitoring forest health. This study aims to determine the value of the health status of the Panca Indah Lestari Community Plantation Forest. This community plantation forest is located in Bukit Layang Village, Bakam District, Bangka Regency, Bangka Belitung Province. The stages of this research include: determining the number of cluster-plots using sampling intensity based on the area of community plantation forest, making cluster plots based on Forest Health Monitoring (FHM) cluster-plot design, collecting data by measuring the ecological indicators of forest health (productivity and vitality) based on the FHM method, as well as data analysis and processing using the Forest Health Assessment Information System. The results showed that the health status of the Panca Indah Lestari Community Plantation Forest had a range of values ranging from 1,890 - 5,530. The average health status value of Panca Indah Lestari Community Plantation Forest is 4,210, which was included in the medium category. Thus, the value of the health status of community plantation forests illustrates that the conditions for productivity and vitality indicators are insufficient. Knowing the forest condition’s status value helps managers provide recommendations in making decisions on sustainable community plantation forest management.

Haneda NF, Retmadhona IY, Nandika D, Arinana. 2017. Biodiversity of subterranean termites on the Acacia crassicarpa plantation. Biodiversitas 18: 1657-1662. The development of industrial plantation forests is one of the efforts to meet the needs of raw material of processing industry of timber forest products. In the last 15 years, the development of industrial plantation forest has grown rapidly. Plant species widely developed is fast-growing plants (fast growing trees) such as Acacia crassicarpa Cunn ex Benth. However, A. crassicarpa has a low resistance against pests, evidenced by the presence of subterranean termites attack occurred in the industrial plantation forest of A. crassicarpa. This aim of the study is to determine the diversity of subterranean termites in plantation forest of A. crassicarpa. Two methods used for data collection: baiting system and survey. Five species of subterranean termites found on sample paths were Coptotermes curvignathus Holmgren, C. gestroi Wasmann, Schedorhinotermes javanicus Kemner, Longipeditermes longipes Haviland, and Pericapritermes mohri Kemner. These species can be distinguished from the morphology of the mandible. Coptotermes is most commonly found Genus in study plots.

The establishment of plantation forests in areas not viable for agriculture can make a significant contribution to the economy. The yield from 1 ha of plantation forest depends on the management purpose - obtaining of round wood (pulpwood, sawnlog, veneer log, tare), bioenergy and extraction of tree foliage (broadleaved and coniferous). In Latvia, based on 2019 data, plantation forests achieve 2760 ha of Scots pine, 7855 ha of Norway spruce, 7431 ha of Birch, 2123 ha of Grey alder, 1274 ha of Black alder and Populus spp. and 618 ha of Salix spp. Estimated and projected gains are calculated both as round wood over 20 to 50 years: pine - 410-to 994 thou. m3; spruce, - 335 to 2.906 thou. m3, birch - 1.040 -2.452 thou. m3. Accordingly, it is possible to obtain gross income from the whole plantation forest area in Latvia: pine-12.42-63.8 mln. EUR; spruce - 40.1 -192.3 mln. EUR; for birch - 32.2 -202.7 mln. Eur. Additionally to that, 18.6 -21.6 t ha-1 and 24.0 -37.0 t ha-1 of processed foliage can be obtained from 1 ha of pine and spruce forest plantations (40-50 years old). Alnus incana sp. (5-20 years), yielding 19.65-122.65 thou. Solid m3 and Salix spp. (3-5 years), yielding 58.71-84.97 thou. solid m3, are used for energy production, furthermore Alnus spp. wood can be used than valuable raw material for plywood production. At the same time, it is possible to capture 106-1477 thou. tonnes of CO2 equivalent. Systematic investigations of chemical composition of above mentioned Latvian plantation trees, wood and bark, have shown that incorporation of extraction treatment in existing processing schemes will allow to manufacture high value added monomeric and oligomeric products which are of great demand for substitution of synthetic ones in different economy sectors (agriculture, including means for plant protection, food industry, polymer production, pharmacy etc.). Creation of small and medium-sized enterprises in rural region in close proximity to plantations opens the opportunity for the appearance of new working places, including organization of new nurseries, plantation services, private businesses for processing of various lignocellulosic waste into new special products / semi-products / feedstock for green industrial materials and chemicals, at the same time diminishing the logistics expenses.

Abstract. Plantation forest area in the conterminous United States (CONUS) ranked second among the world’s nations in the land area apportioned to forest plantation management. As compared to the naturally-regenerated forests, plantation forests demonstrate significant differences in biophysical characteristics, and biogeochemical and hydrological cycles as a result of more intensive management practices. Inventory data have been reported for multiple time periods at plot, state and regional scales across the CONUS, but there lacks the requisite annual and spatially-explicit plantation data set over a long-term period for analysis of the role of plantation management at regional or national scale. Through synthesizing multiple inventory data sources, this study developed methods to spatialize the time series plantation forest and tree species distribution data for the CONUS over the 1928–2012 time period. According to this new data set, plantation forest area increased from near zero in the 1930s to 268.27 thousand km2 by 2012, accounting for 8.65 % of the total forest land area in the CONUS. Regionally, the South contained the highest proportion of plantation forests, accounting for about 19.34 % of total forest land area in 2012. This time series and gridded data set developed here can be readily applied in regional Earth system modeling frameworks for assessing the impacts of plantation management practices on forest productivity, carbon and nitrogen stocks, and greenhouse gas (e.g., CO2, CH4 and N2O) and water fluxes at regional or national scales. The gridded plantation distribution and tree species maps, the state-level tree planting area and plantation distribution area during 1928–2012 are available from doi:10.1594/PANGAEA.873558.

Abstract. Plantation forest area in the conterminous United States (CONUS) ranked second among the world's nations in the land area apportioned to forest plantation. As compared to the naturally regenerated forests, plantation forests demonstrate significant differences in biophysical characteristics, and biogeochemical and hydrological cycles as a result of more intensive management practices. Inventory data have been reported for multiple time periods on plot, state, and regional scales across the CONUS, but the requisite annual and spatially explicit plantation data set over a long-term period for analysis of the role of plantation management on regional or national scales is lacking. Through synthesis of multiple inventory data sources, this study developed methods to spatialize the time series plantation forest and tree species distribution data for the CONUS over the 1928–2012 time period. According to this new data set, plantation forest area increased from near zero in the 1930s to 268.27 thousand km2 in 2012, accounting for 8.65 % of the total forestland area in the CONUS. Regionally, the South contained the highest proportion of plantation forests, accounting for about 19.34 % of total forestland area in 2012. This time series and gridded data set developed here can be readily applied in regional Earth system modeling frameworks for assessing the impacts of plantation management practices on forest productivity, carbon and nitrogen stocks, and greenhouse gases (e.g., CO2, CH4, and N2O) and water fluxes on regional or national scales. The gridded plantation distribution and tree species maps, and the interpolated state-level annual tree planting area and plantation area during 1928–2012, are available from https://doi.org/10.1594/PANGAEA.873558.
