“…Because of their fast and abundant seed production and their wide ecological tolerance, both are potentially suitable for dry forest restoration programmes. C. spinosum is also highly recommended in soil bioengineering for riparian forest restoration [51]. The climax species, Guaiacum officinale, is an evergreen species with a slower growth rate.…”

The characterisation of ecological strategies to predict drought response is still lacking for Caribbean dry forest seedlings. This study documents growth characteristics and tolerance to drought via xylem hydraulic and leaf cell properties of three dominant native species of the Caribbean dry forest. Twenty morphological and physiological traits were assessed in Citharexylum spinosum, Guaiacum officinale and Guapira fragrans in greenhouse conditions. The seedlings displayed contrasting growth rates, which were positively correlated with the capacity to quickly develop a large leaf area and root fraction. The three species had a similar xylem tolerance to embolism (P50: −4 MPa) but differed in leaf cell tolerance to dehydration, which was negatively correlated with RGR (R2 > 0.87). The slowest-growing, G. officinale, had high leaf tolerance to cell dehydration due to low ΨTLP and πo, but displayed a narrow hydraulic safety margin. The leaves of the fast-growing C. spinosum were sensitive to leaf dehydration but exhibited a surprisingly wide stem hydraulic safety margin. G. fragrans had intermediate traits. Our results showed that dry forest seedling growth in similar environments can exhibit distinct carbon growth strategies as well as contrasting water-use strategies, primarily as they relate to drought resistance, due to variation in root development and leaf cell resistance to dehydration. Our study thus provides an approach to estimate species performance under drought conditions.

“…Der-Guey Lin et al [4] established a three-dimensional numerical root model consisting of an inverted t-shaped rootstock and limiting hairy roots based on the actual root morphology in order to study the shear strength characteristics of the soil root system in Makino bamboo forests and successfully applied it to the numerical simulation of in situ uprooting tests of the soil root system. This paper proposes a vegetation slope protection method that uses the combined support of live stumps and bamboo anchors [5,6]. Addressing the initial stage of live stump root development, a stage in which it fails to provide deep-root anchorage and shallow-root reinforcement to the slope [7,8], temporary support is applied to the roadbed slope using bamboo anchors and wooden frame beams.…”

In order to investigate the dynamic response of embankment slopes supported by wooden frame beams and bamboo anchor rods under train loading, this study conducted model tests on embankment slopes supported by wooden frame beams and bamboo anchor rods and carried out three-dimensional numerical simulations of the slopes. This study focused on analyzing the effects of train loading frequency, the peak value difference, and the peak value of the soil pressure on the embankment slopes. This study also analyzed the horizontal displacement of the slope surface, the internal forces in the support structure, and the slope safety factor. The results indicated the following: (1) The increase in loading frequency from 2 Hz to 3 Hz resulted in a significant increase in dynamic soil pressure, with a smaller increase observed upon further frequency increments. Moreover, increasing the load or peak value difference led to an overall increase in the maximum dynamic soil pressure. (2) Under various loading conditions, the axial force in the top anchor rod was significantly greater than that in the middle anchor rod. Additionally, the axial force in the rod body exhibited a pattern of larger forces near the anchorage end and smaller forces near the anchor head. The location of the maximum bending moment in the anchor rod transitioned from the anchor head to the anchorage end as the slope depth increased. The bending moment of the anchor rod increased with the loading frequency but decreased with an increase in the peak value, showing a minor influence from the upper and lower peak values. (3) With the presence of this support system, the slope safety factor increased by 20.13%. A noticeable reduction in the horizontal displacement of the slope surface was observed, with the greatest reduction in the top slope area, followed by the slope angle.

“…The plants used in SWBE techniques must be native pioneer species that are easily propagated and able to grow quickly in degraded areas and under adverse conditions, developing a dense root system and providing good ground cover. Furthermore, the selected plants should preferably exhibit high tolerance to flooding and burial, drought resistance and ecological value (Evette et al, 2012;Ghestem et al, 2014;Stokes et al, 2014;Mira et al, 2022).…”

Soil and water bioengineering (SWBE) is a feasible, economical and ecologically friendly alternative to restore the riparian forest areas affected by the Brumadinho mining tailings dam rupture. We evaluated the vegetative propagation capacity by cuttings and initial development of nine native riparian species of the Paraobepa River for use in SWBE techniques. From the results it is possible to separate the species into two distinct groups, namely those that can resprout and produce roots from their cuttings (group 1: Acnistus arborescens (L.) Schltdl., Croton urucurana Baill., Gymnanthes schottiana Müll.Arg., Indigofera suffruticosa Mill. and Sesbania virgata (Cav.) Poir.) and are suitable for use as live cuttings in SWBE techniques; and those which were only able to produce shoots (group 2: Casearia decandra Jacq., Chrysophyllum marginatum (Hook. & Arn.) Radlk., Inga vera Willd. and Schinus terebinthifolia Raddi) and should only be used in seedling form to increase the diversity of the interventions.
