“…However, in drier dehesas the opposite situation has been observed as a consequence of interception and transpiration, which determines a decrease of water input and an increase of water output beneath the canopy, respectively (Cubera and Moreno, 2007;Martínez-Fernández et al, 2007;Mateos-Rodríguez and Schnabel, 2001). These findings can be supported by the study of Lozano-Parra et al (2015a), who observed that the role of vegetation cover was more decisive under drier environmental conditions. In this situation, the interception capacity by tree canopies was greater than in wet periods, since rainfall events lower than 6 mm never caused soil hydrological response beneath the canopies.…”

“…Hydrological modeling was carried out by Maneta et al (2007) and van Schaik et al (2008) investigated the role of preferential flow on runoff production. More recently work was carried out by Lozano-Parra et al (2015a) on soil water dynamics in dehesa.…”

“…If shorter periods than a hydrological year are considered, the increase or decrease of soil moisture beneath the tree canopy should not be generalized, since the canopy effect could be variable according to environmental conditions or the period analysed (Fig. 7) (Gea-Izquierdo et al, 2009;Lozano-Parra et al, 2011;Lozano-Parra et al, 2015a). This can be seen in Figures 7A and B, where soil water contents vary between covers through the year.…”

“…In semiarid environments, it has been explained as a consequence of interception and transpiration, which determines a decrease of water input and an increase of water output beneath the canopy, respectively (Gea‐Izquierdo et al, ; Moreno, ). Supporting our observations, Lozano‐Parra et al () found that the role of tree canopies on soil moisture was more decisive under drier environmental conditions. In this situation, the interception capacity by tree canopies was greater than in wet periods, because precipitation events with low rainfall (<6 mm) never caused soil hydrological response beneath the canopies.…”

Effects of soil moisture and vegetation cover on biomass growth in water‐limited environments

Soil moisture has a direct influence on biomass production, food security, and ecosystem functioning, thus resources management in water‐limited environments could be improved if feedbacks between water and vegetation were fully understood. This study tries to define the sensitivity of annual pastures under the influence of different vegetation covers to soil water availability during two contrasting growing seasons, dry and wet. For this reason, soil water content was continuously monitored during two complete hydrological years using capacitance sensors, which were gathered in soil moisture stations located in open grasslands and beneath tree canopies. Pasture growth was recorded by measurements of its height and by biomass cuts. The study was conducted on three private farms located in savanna‐like ecosystems of Spain (dehesa) with Mediterranean climate. Results highlighted the importance of the topsoil (first 15 cm) as the main layer for water supply of natural grasses. Soils below canopies registered longer and more intense water deficits than those located in grasslands. This was reflected in biomass growth, given that when growing conditions were dry, pasture yield decreased more than 40% in grasslands and more than 50% below tree canopies. The studied ecosystems occupy millions of hectares in Spain and Portugal and present a canopy cover up to 40%. If dry episodes become more frequent in the present century due to climate change, important surface, especially under trees, could become drier, less productive, and therefore more prone to land degradation.

Rainfall partitioning by the vegetation canopy into stemflow (SF) and throughfall (TF) plays a crucial role in soil infiltration and the local water balance. This study aims to quantify the differences in SF and TF between two sand‐binding shrubs, Caragana liouana and Salix psammophila, in the desert steppe, clarify the effects of biotic and abiotic factors on them using the boosted regression trees (BRT) model, and compare soil moisture replenishment during the growing seasons of 2021 and 2022. Under identical rainfall conditions, the canopies of C. liouana and S. psammophila can lead to differences in rainfall partitioning. The SF percentage ranged from 0 to 23.70% for C. liouana and from 0% to 3.3% for S. psammophila, respectively, while the TF percentage ranged from 42.12% to 90.07% for C. liouana and from 52.39% to 94.87% for S. psammophila. The funnelling ratio for C. liouana (69.59) is 1.19 times higher than for S. psammophila (58.36). Rainfall amount is the primary variable affecting rainfall partitioning. The average soil moisture replenishment and soil moisture conversion efficiency under the C. liouana canopy are 11.02 mm and 58.39%, respectively, which are significantly higher than those for S. psammophila (4.84 mm and 24.33%, respectively). These findings suggest that C. liouana, with its relatively higher SF and soil moisture conversion capability compared to S. psammophila, plays a significant ecohydrological role in water‐limited ecosystems. This study provides a reference for species selection and ecological management in vegetation restoration efforts in desert steppes and similar regions.
