{"title":"Conversion of an abandoned bamboo forest to a broadleaf forest by application of herbicide and culm cutting","authors":"Y. Hisamoto, H. Egami, S. Suzuki","doi":"10.5738/jale.25.163","DOIUrl":"https://doi.org/10.5738/jale.25.163","url":null,"abstract":": Bamboo forest expansion is a well-known problem, not only in Phyllostachys pubescens but also in P. bambusoides . The conversion of abandoned bamboo groves to broadleaf forests is desirable for ecosystem function. We first investigated the effects of sodium chlorate (Chlorate S) on plant germination following disturbance by conducting a three-month sowing test. Next, we established three plots in an abandoned P. bambusoides stand in Chiba Prefecture, Japan, in May 2013 to compare the changes in vegetation over 5 years. To prepare the plots, clear-cutting of bamboo culms was carried out in all plots and chemical treatment was applied to two for examining the effects of chemical treatment on revegetation. The results of the sowing test showed the presence or absence of the chemical had no significant effect on the number of germinated species, although the response to the chemical was species-dependent. The density and average diameter of regenerated bamboo culms were lower in the chemically-treated plots than in the untreated plot. In the chemically-treated plots, bamboo culm regeneration was suppressed after September 2013, whereas other plants grew abundantly. Regenerated bamboos thrived in the non-treated plot until October 2014, after which other plants increased. By the third year, broadleaf trees were growing in all plots. The chemical treatment did not almost affect the growth of seedling-derived trees adversely and few differences in species composition emerged between treated plots and the untreated plot. Our study demonstrated that it is essential to leave as many woody species as possible when clear-cutting culms and that chemical treatment can also be an effective method for forest conversion.","PeriodicalId":176820,"journal":{"name":"Landscape Ecology and Management","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126228284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Drey site selection of Japanese squirrels in the cool temperate zone: evaluation at multiple spatial scales","authors":"Suzuka Honda, Masayuki U. Saito","doi":"10.5738/jale.26.45","DOIUrl":"https://doi.org/10.5738/jale.26.45","url":null,"abstract":": In this study, we clarified the drey site selection of Japanese squirrels living in cool temperate zone at three spatial scales (landscape, stand, and tree). The survey was conducted in a forest area of the Shonai region, Yamagata Prefecture. From March to May 2020, we searched for globular nests along seven survey routes. We also conducted a plot survey from August to November 2020 to investigate the forest structure of some drey trees found in the route survey. To examine selectivity at the landscape scale, we analyzed the relationship between drey sites and environmental factors (topography, distance from bodies of water, and forest type). At the stand-scale, we analyzed whether there were differences in mean tree height, mean diameter at breast height (DBH), and number of standing trees between drey and non-drey plots. At the tree scale, we analyzed whether there were differences in tree height, DBH, and species composition between drey and non-drey trees. The results of the landscape-scale analysis showed that Japanese squirrels significantly selected deciduous and evergreen coniferous forests as drey sites, with evergreen coniferous forest being relatively more important. Plots with fewer standing trees were selected as drey sites at the stand-scale. Trees with higher height and a larger DBH were significantly selected at the tree scale. The drey selection of Japanese squirrels differs depending on the spatial scale; therefore it is important to evaluate drey site selection at multiple scales.","PeriodicalId":176820,"journal":{"name":"Landscape Ecology and Management","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121281109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Vegetation mapping with the aid of aerial images taken by UAV with a near-infrared sensor","authors":"Hideyuki Niwa, Sin Morisada, M. Ogawa, M. Kamada","doi":"10.5738/jale.25.193","DOIUrl":"https://doi.org/10.5738/jale.25.193","url":null,"abstract":"Vegetation map is an essential material in regional/local planning as well as environmental assessment, and it has been created by phytosociological field survey with an aid of aerial photographs and/or satellite images. The UAV (unmanned aerial vehicle) becomes strong tool as low altitude remote sensing (LARS) in vegetation mapping, because it can provide high resolution images whenever and wherever desired. An aim of the study is to develop a technology of vegetation mapping for local planning, through a case study at a forest in Tkaragaike Park of Kyoto City, Japan. Phytosociological survey was conducted at 74 locations in the forest from 21 to 23 of June 2019, and 7 plant communities were distinguished based on species composition and vegetation height; Pinus densiflora Rhododendron reticulatum community, Quercus serrat Q. variabilis community, Castanopsis cuspidata community, Cryptomeria japonica Chamaecyparis obtusa plantation and their sub-communities. Prior to the phytosociological survey, aerial photographs were taken by using UAV from March to May in 2019. Near-infrared sensor was used to take aerial photographs in March, because the season was easy to distinguish the boundaries of evergreenand summer green-type forests, and to find evergreen trees under the canopy of deciduous trees. Normalized difference vegetation index (NDVI) was also calculated from the images to evaluate a density of evergreen trees. May is the blooming season of C. cuspidata and thus it is suitable to identify its area. Using the Digital Surface Model (DSM) produced from the LARS images and Digital Terrain Model (DTM) provided from Kyoto City, the canopy height model (CHM) was created. The location of every individual of P. densiflora was identified from the LARS image by a method of deep learning, and the density of P. desiflora was calculated in a circle with 10 m radius from every tree of P. densiflora. By linking those spatial attributes obtained from LARS images with attributes of phytosociological communities, vegetation boundaries were fixed and map was produced. The method developed in the study is cost-effective and applicable to any other areas.","PeriodicalId":176820,"journal":{"name":"Landscape Ecology and Management","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121461721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
