Synopsis (short abstract) To coping with international convention and treaty relating with biological diversity, and to enhance the public awareness on the effect of forest practice on biodiversity and sustainable forest management in Korea, we evaluated the thinning effect on bird communities at Larch plantation forests (LF, 25.0% thinning at 9ha in size, a.s.l. 1,200m) and deciduous forests (DF, 55.3% thinning at 15.8ha in size, a.s.l. 600m) after two years from 2013 to 2015. Bird communities were surveyed by the combination of point counts (9 points) and line transect methods during breeding and non-breeding seasons with the sounds and observation by binocular and camera. We analyzed the composition of bird communities with nesting and foraging guild. After thinning practice in early spring of 2013, total 15 and 21 birds were recorded in 2013, forty and thirty-one species of birds in 2014, and sixty and forty species of birds in 2015 at the DF and LF, respectively. Data showed that one year took to recover the number of species after thinning at DF sites, and bush-nesting birds such as Winter Wren and Hazel Grouse were increased after thinning at LF sites. At a large forests area in Mt.Jungwangsan, forest practice like a 25.0% thinning at LF and 55.3% thinning at DF sites could not affect the bird community and increase the habitat diversity to attract the forests birds prefer bush and open space in forests areas. These results imply that spatial and temporal arrangement in a landscape approach could be fully considered to maintain and enhance biodiversity in forests.

    Land use and land use changes by the farmers from mulberry (Morus alba) plantations to green forest tree based farming for income growth and sustainability in Malda district of India

    Malda district was famous for two economic activities viz. Mango (Mangifera indica) cultivation and rearing mulberry silkworm (Bombyx mori). Earlier silkworm rearing was a flourishing cottage industry and every households of Kaliachak block reared silkworm for cocoon production. It was the major livelihood of rural farmers but they suffered heavily due to cheap import of silk from China. Thus, the backbone of farmers was crippled, hence they started cultivating various trees in mulberry fields along with agricultural crops for sustaining their livelihood. Present study was undertaken to know how farmers adjusted to new situation, their knowledge about trees, income growth and sustainability. It was observed that mulberry was raised as herb and leaves were fed to the silkworm larvae at home. Traditionally farmers planted Dalbergia sissoo trees on the border of mulberry fields but later on they started planting other trees. A few farmers uprooted their mulberry bushes and converted to Swietenia macrophylla plantation. Some farmers converted their entire land to Mango and Litchi chinensis orchards for long term gains. Besides, some traditional farmers, around 10% still continued with silkworm rearing for their livelihood security but planted few rows of trees like Tectona grandis, D.sissoo, Bombax ceiba, S.macrophylla and Acacia auriculiformis. Few big farmers converted their mulberry fields into ponds for fishery, however, planted Mango and Sissoo on border. The first crops inside the tree plantations were Maize, Papaya and Vegetables which gave farmers quick income. Later, Banana and Citrus were planted. These activities are still continuing, but timber harvesting has also started which will give high returns. These forest tree based land changes not only provided sustainable income growth to farmers, but also made them drought resilient leading to climate change mitigation and adaptation besides conserving plant biodiversity.

    Review of methodology on climate change impact and vulnerability assessment for application to the forest sector in Republic of Korea: The first step for mainstreaming adaptation in forest sector

    As the two laws, The Framework Act on Agriculture and Fisheries, Rural Community and Food Industry and The Creation and Management of Forest Resources Act, were revised in 2015 and 2019, respectively, the Korean government made it mandatory for Korea Forest Service to report the results of climate change impact and vulnerability assessment on forest sector. For implementing the above duty, the National Institute of Forest Science (NIFoS) has categorized the forest sector to eighteen detailed sectors and established monitoring framework to assess the climate change impacts since 2015.
    This study aims to develop appropriate methodology and framework for assessment of climate change impact and vulnerability on forest sector in Korea by reviewing what the NIFoS has conducted in comparison with the previous cases in the USA, Canada and the UK. To achieve this, this study first clarifies the ultimate goals of assessment and categorizes assessment areas for each detailed sector. Then, by reviewing the major factors on vulnerability assessment used in the Adaptation Partners Frameworks (USA), the Climate Change Response Framework (USA), the Canadian Council of Forest Ministers Framework (Canada), and the Climate Change Risk Assessment (UK), this study draws the possible stepwise check list with the hope of producing appropriate results on climate change impact and vulnerability which can be utilized in the stage of mainstreaming adaptation in forest sector. The tentative framework drawn from this study contains the considerations about where we need to go and how to go for achieving adaptation.
    This study is expected to contribute to establish the essential basis for supporting decision making for finding actual tools to conserve and enhance forest ecosystem services and sustain life of human being under climate change pressure.

    Local climate mediates spatial and temporal variation in carabid beetle communities in three forests in Mount Odaesan, Republic of Korea

    Global environmental change can dramatically alter the composition of floral and faunal communities, and elucidating the mechanisms underlying this process is important for predicting its outcomes. Studies on global climate change have mostly focused on statistical summaries within wide spatial and temporal scales; less attention has been paid to variability in microclimates at narrower spatial and temporal scales. The microclimate is the suite of climatic conditions measured in a local area. Environmental variables at the microclimatic scale can be critical for the ecology of organisms inhabiting each area. We examined the effect of spatial and temporal changes in the microclimate on the ecology of carabid beetle communities in three sites on Mount Odaesan, Korea. Our results demonstrate the importance of regular surveys of communities at local scales. Such surveys are expected to reveal an additional fraction of variation in communities and underlying processes that have been overlooked in studies of global community patterns and change.
