However, the effects of exponential fertilization under varying fertilization levels on seedlings’ growth, nutritional status, and nonstructural carbohydrates (NSC) are poorly understood. We employed Armand pine (Pinus armandii) seedlings to investigate the responses of growth, nutrients (nitrogen, phosphorus, and potassium) in seedlings, and NSC in organs to varying exponential and conventional fertilization levels. Shoot height, root collar diameter, and biomass increased and then declined with the increased fertilization levels. At high fertilization levels (≥300 mg seedling−1), the seedings accumulated more biomass in exponential fertilization than in conventional fertilization. The exponentially fertilized seedlings contained more concentrated nitrogen, starch, and NSC than the conventionally fertilized ones. Vector analysis revealed that conventional fertilization of 200 mg seedling−1 or exponential fertilization of 300 mg seedling−1 could induce luxury consumption. NSC was closely related to the nutrient states. With the increased fertilization level, regardless of the regime, soluble sugar concentrations in roots and needles trended toward declining with changes in the nutrient supply from deficiency to sufficiency and then increased with the changes from sufficiency to toxicity. Meanwhile, starch and NSC concentrations in roots and needles increased with the changes in the nutrient supply from deficiency to sufficiency; the concentrations in roots decreased with the changes from sufficiency to excess. Exponential fertilization at high levels did not only promote seedling growth but also induced seedlings to reserve more nutrients and NSC, which could improve afforestation success.","PeriodicalId":15839,"journal":{"name":"Journal of Forest Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44437980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are still deficiencies in the scientific recognition and accurately assessment for the health status of the Moso bamboo forest. Using an index system to quantitatively assess the health of Moso bamboo (Phyllostachys edulis) forest can provide an intuitional recognition for the status of Moso bamboo forest. Here, the health assessment index system of the Moso bamboo forest was established by literature collection, Analytic Hierarchy Process (AHP), and expert questionnaire. The health index of the Moso bamboo forest was calculated by the comprehensive health index. The practicability and feasibility of the health assessment index system were then verified by the Moso bamboo forest in Anhui and Fujian provinces of China. The health index of the Moso bamboo forest in Anhui and Fujian provinces ranged from 0.50 to 0.83. The health index of the Moso bamboo mixed forest generally performing higher than that of the pure Moso bamboo forest. Only 2.35% of the Moso bamboo forest health index scored higher than 0.80, whereas 22.35% scored lower than 0.60. These results suggested that the health status should be improved in most of the Moso bamboo forest. The health assessment index system provides an important tool to guide Moso bamboo forest resource management and prioritize scientific research.","PeriodicalId":15839,"journal":{"name":"Journal of Forest Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136144126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deer overgrazing has occurred soil erosion in Japanese beech forests where dwarf bamboo used to be densely covered. Soil erosion can result in a decrease in soil carbon and nutrient contents, causing the soil microbial respiration in such forest ecosystems to be degraded. The objective of this study was to clarify the effects of soil erosion, which sporadically occurs within the forests, on soil properties and microbial activity. Soil erosion indices, such as the maximum height of exposed roots from the soil surface (MAXH), tree and soil properties, microbial basal and substrate-induced respiration, were measured under the canopy of 16 beech trees in each of three deciduous broadleaved forests on southern Kyushu Island, Japan. Soil properties such as the humus mass and the organic matter contents of soil and humus decreased with MAXH. Basal and substrate-induced respiration decreased with increases in MAXH. Soil properties associated with organic matter increased with basal and substrate-induced respiration. These results suggest that soil surface layers that were rich in organic matter ran off because of soil erosion, resulting in the degradation of soil microbial activity. This study suggests that increases in wild herbivore populations degrade soil ecosystem functioning owing to the soil erosion induced by understory disappearance.","PeriodicalId":15839,"journal":{"name":"Journal of Forest Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41375321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

University students, a group highly vulnerable to these problems, are likely to develop mental pathologies associated with anxiety and substance abuse. Forest bathing is one nature-oriented intervention aimed at improving physical as well as psychological well-being by reducing anxious symptomatology and stress. Here we evaluated the healing impact of forest bathing on the stress and anxiety of undergraduate students at one local university. We also included others key aspects of psychological mental health that have received scarce attention in forest bathing research like mindfulness, wellbeing and self-regulated learning. Twenty-one students belonging to the Universidad Austral de Chile were randomly assigned to the city or forest groups and took part in an intervention consisting in a low-impact 30 minute walk and a 15-minute contemplation afterwards. Five instruments to evaluate overall mental health (and blood pressure) were applied before and after the intervention. Our results showed that a rather short session of forest bathing is enough to reduce anxiety in undergraduate university students. The other measures of psychological or physiological health showed no statistical differences before and after the intervention (between city and forest) or time effects (within the forest or city treatment). A potential reason for this might be related to the short duration of the intervention itself. Our results are encouraging regarding mental health therapy, as this type of intervention could easily be implemented on campus.","PeriodicalId":15839,"journal":{"name":"Journal of Forest Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41703437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the capacity of bamboo forests to sequester and store carbon has not been assessed on a national scale in Japan. This study estimates the changes in the carbon stock of bamboo forests (CSbamboo) in Japan from 1985 to 2005. We compiled two data sets: (1) administrative statistical data on bamboo stand area (BSA) and (2) published data on stand-level aboveground biomass for Phyllostachys pubescens Mazel ex Houz. (n = 44) and Phyllostachys bambusoides Sieb. et Zucc. (n = 13). The BSA expanded from 147 kha in 1985 to 158 kha in 2005. The average carbon density (CD) of managed and abandoned stands were 84.9 Mg C ha−1 and 115.1 Mg C ha−1 for P. pubescens and 24.1 Mg C ha−1 and 46.4 Mg C ha−1 for P. bambusoides, respectively. The CD of P. pubescens stands in Japan was higher than that in other Asian countries and regions and was comparable to the CD of other forests in Japan. The area-based method indicated that the CSbamboo increased from 10.1 ± 2.6 Tg C to 13.9 ± 1.7 Tg C during the 20-year period, representing less than 1% of the total carbon pool of the forested area. The increase in CSbamboo was primarily caused by the synergistic effect of the abandonment and range expansion of P. pubescens forests. Our results suggest that P. pubescens forests are overstocked, and the increase in the CSbamboo is undesirable.","PeriodicalId":15839,"journal":{"name":"Journal of Forest Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47545689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have examined the correlation between forest types and ages, and shallow landslide susceptibility, but causal effects of forest type and age on shallow landslide susceptibility are yet not clear. This study investigated the causal effect of forest type and age on shallow landslide susceptibility using a propensity score method by combining existing geo-data sets. Here, we focus on shallow landslides caused by an extreme rainfall event on 5–6 July 2017, in the mountainous areas of Asakura City and Toho Village, Fukuoka Prefecture, Japan. Randomly located samples of coniferous forest, broadleaved forest, and young forest exposed to shallow landslide events were analyzed. The inverse probability of treatment weighting with the propensity score was applied to the samples to compare the differences in shallow landslide susceptibility among the three forest classes. Young forest had increased shallow landslide susceptibility, compared with coniferous forest and broadleaved forest, by 3.70 × 10−2 and 4.12 × 10−2, respectively, which corresponded to a two to three times increase in shallow landslide susceptibility when the forest changes from coniferous or broadleaved forest to young forest. No significant difference in shallow landslide susceptibility between coniferous forest and broadleaved forest was observed. These differences in shallow landslide susceptibility should be considered when implementing forest management schemes.","PeriodicalId":15839,"journal":{"name":"Journal of Forest Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43826598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
