“…By the field survey in CC, we identified sediment captured by the branches of harvested trees, especially where branches were piled up by forestry operations. Previous studies also reported that litters and woody debris on the ground prevented sediment transport (Hartanto et al, 2003;Liu et al, 2017). Thereby, interruption of sediment 30 transport by branches resulted in differences in sediment transport activity between the micro and the hillslope scales, as monitored by TLCs and sediment traps, respectively.…”

Abstract. Sediment transport activities in the periglacial environment are controlled by hillslopes micrometeorological conditions (i.e., air and ground temperatures, ground water content), which are highly affected by vegetation cover. Thus, there is a possibility that forest harvesting, which is the most dramatic change to vegetation cover in mountain areas, may severely impact sediment transport activities in periglacial areas (i.e., soil creep, dry ravel). Knowledge of the effects of forest harvesting on sediment transport are needed to protect aquatic ecosystems as well as to develop better mitigation 15 measures for preventing sediment disasters. In this study, we investigated changes in sediment transport activities following forest harvesting in steep artificial forests located in a humid periglacial area of the Southern Japanese Alps. In the Southern Japanese Alps, rainfall is abundant in summer and autumn, and air temperatures frequently rise above and fall below 0 degrees in the winter. Our monitoring by time laps cameras revealed that gravitational transport processes (e.g., frost creep and dry ravel) dominate during the freeze-thaw season, while rainfall-induced processes (surface erosion and soil creep) 20 occur during heavy rainfall seasons. Removal of the forest canopy by forest harvesting alters the type of winter soil creep from deeper frost creep to diurnal needle-ice creep. Winter creep velocity of the ground surface sediment in the harvested site was significantly higher than that in the non-harvested site. Meanwhile, sediment flux on the hillslopes observed by sediment traps decreased in the harvested site. Branches of harvested trees left on the hillslopes captured sediment coming from upslope. In addition, the growth of understories after harvesting possibly reduced surface erosion. Consequently, 25 removal of the forest canopy by forest harvesting directly impacts micrometeorological conditions and periglacial sediment transport activity, while sediment flux on hillslopes is also affected by branches left on the hillslopes and recovery of understories.

“…11). The contributing area may affect rapid sediment transport with long travel distances (i.e., dry ravel and rockfall) rather than slow sediment transport (i.e., soil creep), which can be explained by local freezing and transport conditions that are unrelated to the size of the contributing area (Higashi and Corte, 1971;Matsuoka, 1998).…”

Sediment transport activities in periglacial environments are controlled by microclimate conditions (i.e., air and ground temperatures, throughfall), which are highly affected by vegetation cover. Thus, there is the possibility that forest harvesting, the most dramatic change to vegetation cover in mountain areas, may severely impact sediment transport activities in periglacial areas (i.e., soil creep, dry ravel). In this study, we investigated changes in sediment transport activities following forest harvesting in steep artificial forests located in a humid periglacial area of the southern Japanese Alps. In the southern Japanese Alps, rainfall is abundant in summer and autumn, and winter air temperatures frequently rise above and fall below 0 • . Our monitoring by time lapse cameras revealed that gravitational transport processes (e.g., frost creep and dry ravel) dominate during the freeze-thaw season, while rainfall-induced processes (surface erosion and soil creep) occur during heavy rainfall seasons. Canopy removal by forest harvesting increased the winter diurnal ground surface temperature range from 2.7 to 15.9 • C. Forest harvesting also increased the diurnal range of net radiation and ground temperature, and decreased the duration of snow cover. Such changes in the microclimate conditions altered the type of winter soil creep from frost creep to diurnal needle-ice creep. Winter creep velocity of ground surface sediment in the harvested site (> 2 mm day −1 on the days with frost heave) was significantly higher than that in the non-harvested site (generally < 1 mm day −1 ). Meanwhile, sediment flux on the hillslopes, as observed by sediment traps, decreased in the harvested site. Branches of harvested trees left on the hillslopes captured sediment moving downslope. In addition, the growth of understories after harvesting possibly reduced surface erosion. Consequently, removal of the forest canopy by forest harvesting directly impacts the microclimate conditions (i.e., diurnal range of ground temperature and net radiation, duration of snow cover) and increases frequency and velocity of periglacial soil creep, while sediment flux on hillslopes is decreased by branches left on the hillslopes and recovery of understories. The impact of forest harvesting on sediment transport activity is seasonally variable in humid periglacial areas, because microclimate conditions relevant to both freezethaw processes and precipitation-induced processes control sediment transport.

“…A ação antrópica tem acarretado a degradação dos solos, principalmente devido ao desmatamento, atividades agropecuárias, construções civis, dentre outros fatores (Silva, 2013). Tais fatores expõem o solo diretamente aos agentes do clima, intensifica a erosão natural, causando grandes prejuízos ao ambiente (Campos et al, 2008;Novara et al, 2011;Borrelli et al, 2015).…”

“…Diante da necessidade de melhorar as práticas de uso da terra para obter uma gestão sustentável, surge a prática de cobertura da superfície do solo (Lieskovský & Kenderessy, 2014;Liu et al;, uma vez que a cobertura do solo atua na dissipação de energia cinética das gotas de chuva, diminuindo a desagregação das partículas do solo e a erosão hídrica (Schaefer et al, 2001), além de promover o aporte de matéria orgânica e nutrientes e reduzir a amplitude térmica do solo ao longo do ciclo da cultura (Saturnino & Landers, 1997).…”

______________________________________________________________________________________Resumo -A degradação dos solos e a perda por erosão por manejo inadequado constituem uma séria ameaça à produtividade agrícola e contribuem para o agravamento de impactos ambientais. Práticas edáficas, vegetativas e mecânicas de conservação dos solos estão sendo desenvolvidas para auxiliarem na atenuação desses problemas. Nesse contexto, a presente pesquisa foi realizada com o objetivo de avaliar o efeito da cobertura morta na conversação de um solo argilo-arenoso no estado do Mato Grosso. O estudo foi desenvolvido em condições de campo na Universidade Federal do Mato Grosso, Campus Rondonópolis e um delineamento inteiramente casualizado com dois tratamentos, com e sem cobertura vegetal, onde se avaliou temperatura do solo, quantificação de plantas espontâneas, umidade do solo e umidade do ar na superfície do solo. Verificou-se que a cobertura morta manteve o solo com um gradiente de temperatura em torno de dois graus inferiores ao tratamento sem cobertura, além de reduzir o surgimento de plantas espontâneas em 36 vezes e elevar a umidade do solo em aproximadamente quatro graus, porém não teve efeito sobre a umidade do ar na superfície do solo. Portanto, O uso da cobertura morta é uma prática vantajosa, a qual melhora as características hidrotérmicas do solo e reduz a incidência de plantas espontâneas.

Soil, vegetative and mechanical practices of soil conservation are being developed to assist in the attenuation of these problems. The present research was carried out with the objective of evaluating the effect of mulching in the conversation of a sandy loam soil in the state of Mato Grosso. The study was developed under field conditions at the Federal University of Mato Grosso, Rondonópolis Campus and a completely randomized design with two treatments, with and without vegetation cover, where soil temperature, spontaneous plant quantification, soil moisture and relative humidity of the soil surface. It was verified that mulching kept the soil with a temperature gradient around two degrees lower than the uncovered treatment, besides reducing the emergence of spontaneous plants in 36 times and raising soil moisture by approximately four degrees, but not had an effect on soil surface moisture. Therefore, the use of mulch is an advantageous practice, which improves the hydrothermal characteristics of the soil and reduces the incidence of spontaneous plants
