“…The investigated trail was divided into five zones, which are hereafter referred to as A‐stony part, A‐without stoniness, B, C and D (see Figure for details). Characterization of ground microtopography can be a critical factor to be considered, as it allows obtaining accurate erosion rates using dendrogeomorphic techniques (Stoffel et al ., ; Ballesteros‐Cánovas et al ., ; Bodoque et al ., ). In that sense, and given the difficulties of TLS portability in mountainous areas, we propose an alternative method based on the use of microtopographic profile gauges (Benito et al ., ; Desir & Marin, ; Figure B and C).…”

“…Alternatively, one can also measure maximum trail incision along perpendicular transects (Dixon et al ., ; Hawes et al ., ; Marion et al ., ). A last possible approach consists of topographic surveys of soil erosion at recreational trails with differential GPS (Tomczyk & Ewertowski, ) or terrestrial laser scanning (TLS) (Ballesteros‐Cánovas et al ., ; Bodoque et al ., ).…”

“…More recently, variability in ground surface microtopography has been included in dendrogeomorphic research, both to improve the reliability of sheet erosion rates and to determinate uncertainty in the estimates. To address this issue, the combined use of TLS and Geographic Information Systems has been shown to represent a highly precise and valuable tool (Ballesteros‐Cánovas et al ., ; Bodoque et al ., ). Nevertheless, the use of TLS may not be feasible in difficult conditions such as natural protected areas in steep mountain environments, as these regions are often difficult to access, even more so with heavy and large TLS equipment.…”

Recreational activities may impose adverse impacts on the environment of natural landscapes and protected areas owing to persistent tourist influx. Here, we use a dendrogeomorphic approach to estimate soil erosion induced by hikers at trails in the Ordesa and Monte Perdido National Park (north‐eastern Spain). For the first time, exposed roots of Pinus uncinata Ramond ex DC and Fagus sylvatica L. were used on the Iberian Peninsula to reconstruct the timing and amount of soil erosion induced by hikers based on dendrogeomorphology. In addition, we propose a new characterization of ground microtopography using a microtopographic profile gauge and validate results of this approach with 3D point clouds derived from terrestrial laser scanning. Determination of the first year of root exposure was based on the analysis of changes in roots, at both the macroscopic and tissue levels. Analysis shows that a distinctive footprint is observable at macroscopic and microscopic scales following initial exposure and thus confirms results of previous work realized with roots of other tree species (e.g. Pinus sylvestris L.). Our results also indicate that a characterization of erosion based on microtopographic profiles can replace terrestrial laser scanning measurements, which are often difficult to obtain in remote areas. Estimates of soil erosion ranged between 3·1 ± 1·5 and 8·9 ± 4·3 mm y−1 (or 52·7 ± 25·5 to 151·3 ± 73·1 t ha−1 y−1). The approach deployed here could help improve management of and access to natural protected areas and thus reduce the potentially negative impacts of recreational activities on these sensitive environments.

“…Non-contact measurement of distance by a laser beam, combined with precise measurement of angles, allows determining XYZ coordinates of the measured point, and in the case of surface analyses, each point from the received points cloud representing the object. Studies using TLS on various types of soil water erosion processes have been conducted in recent years in many countries [22][23][24][25][26][27].…”

Abstract. In the terms of forest soil protection function and the limitations of these functions resulting from forest works, the authors aim was to determine the intensity and spatial range of erosion, and the volume of soil material loss resulting by erosion processes and human activities. The remote sensing technique -terrestrial laser scanning (TLS) was used in the research of erosion processes occurring in the mountain forest on the surface of the skid trails. The measurements were performed with laser scanning resolution of 3x4 mm. Obtained points clouds have been interpolated to the digital terrain models 1 cm, which allowed evaluating the erosion phenomena using the method of differential models in the period of 2011-2013. In the study it was analysed the part of the skid trail (ca. 41 m 2 , ca. 35% average slope). It was determined that during the entire research period the amount of soil material loss was ca. 1.9 m 3 . The erosion processes occurred mainly in the form of sheet erosion with volume ca. 1.3 m 3 . The erosion processes in the form of sheet erosion occurred ca. 49% and 42% of trail section area, respectively. Results of the study indicate that it is efficient to use TLS for the monitoring of the erosion phenomena, qualitative and spatial range assessment. At the same time, it has been proven that intensive water erosion processes can also occur in forests.

“…Moreover, the precise position of samples must be recorded. Dendrogeomorphology and tree-roots were successfully used for analysis of spatio-temporal activity of debris flow [20,21], rockfall [22,23], landslides [24][25][26], floods [27][28][29][30] and erosion processes [31,32]. E.g.…”

Dynamics of gully side erosion: a case study using tree roots exposure data

2016

Erosion is a frequently studied natural process. Unfortunately, detailed analysis mostly requires longterm field monitoring or detailed digital elevation models (DEM) which are still absent for many areas. For these reasons we used the dendrogeomorphic method, a valuable tool for erosion analysis. The slopes of a~220 m long gully close to the Kozárovce village (Slovakia) were the object of our study. We analyzed 53 tree root samples coming from 16 broad-leaved trees of different species. 23 erosion event years were explored during the reconstruction period AD 1972-2013. The mean erosion rate E R was 1.00 cm/year. We were able to create four erosion patterns of slope erosion based on subsequent exposure of different parts of root. These erosion patterns serve as a base for a model of gully cross profile development. The highest values of erosion rate were reconstructed in the lowest parts of gully slopes. The gully sides formed by volcanic rocks are affected by lateral retreat here. Upward erosion dominates in the middle parts of slopes in loess, and downward erosion in the highest parts of the slopes.
