“…It is accomplished by plowing the soil in the superficial horizons or removing a superficial layer of soil and litter, in order to reduce competition and release resources (light, space, water and nutrients) in favor of the regeneration -natural or artificial regeneration-of interest forest species (Resco de Dios et al, 2005., Aoyama et al, 2009. It eliminates or mitigates competition with other species and exposes the mineral soil, which is usually covered by a litter thick in colder climates (it has been commonly used in boreal or low temperature forests).…”

“…It eliminates or mitigates competition with other species and exposes the mineral soil, which is usually covered by a litter thick in colder climates (it has been commonly used in boreal or low temperature forests). However, this method decreases soil fertility (Zaczek, 2002;Resco de Dios et al, 2005;Gastadello et al 2007;Hope, 2007). In the case of Chilean species, scarification favors the establishment of Nothofagus species, which have catastrophic regeneration mode, since they establish themselves after disturbances such as landslides and volcanic eruptions in the Andes area (Veblen and Ashton, 1978;Veblen et al, 1996).…”

Soil scarification has been used as a silvicultural method to eliminate competition in tree regeneration, but it modifies soil characteristics. In order to evaluate soil changes due to silvicultural management, we characterized a volcanic soil subjected to a mechanized scarification in a Nothofagus spp. forest in the Andean region of southern Chile (39° 54' S, 71° 56' W; 970 m asl). Scarification removed between 20 and 40 cm of topsoil in forest gaps. Two scarified areas were selected in different periods and in an undisturbed forest area. Physical properties (bulk density, penetration resistance, porosity, texture) and chemical (pH, soil organic matter, total-N, P-Olsen, K, Mg and Ca extractable, Al saturation) were analyzed in both the scarified soil and undisturbed forest. The morphology of the soil was a result of the formation of a stratified soil. Bulk density was higher in the superficial layer of the scarified soil (0.9 to 1.2 g cm -3 ) when compared to the undisturbed forest (0.3 g cm -3). With regards to the undisturbed forest, soil scarification exposed a superficial soil of coarser texture, lower total porosity (50-60% vs. 80%) and it decreased the soil nutrient supply. There were no large variations in soil properties when comparing the oldest scarified soil with the most recent one. There were important changes in morphology, physical and chemical properties of the scarified soil.

“…We also note that the extension growth of these saplings was similar between the treatments (data were not shown). Larger B. ermanii seemed to produce facilitative effects rather than competitive effects in this stage of stand development (Resco de Dios et al 2005;Harada et al 2008).…”

We examined an alternative natural regeneration practice with a scarification treatment, in which removed soil is replaced on the scarified area, in northern Japan. The effect of the soil replacement on tree establishment was quite obvious; the basal area of trees, composed mostly of Betula ermanii, in the soil-replaced site was about 150-fold greater than that of the normally treated site. The greater growth rates together with higher density, both of which seemed to be enhanced by improved (i.e., deeper, tender, and nutrient-rich) soil properties, produced the marked difference to the normally treated site. The expected enhancement of species diversity owing to utilizing buried seeds in the replaced soil was not found. The current study revealed that the soil replacement could substantially improve forest restoration management with emphasis on biomass production for large nonwooded sites.

“…This might also contribute to the recovery of natural vegetation, because regeneration in NRss contained a more diverse overstory component ( Fig. 1), probably resulting from a more abundant seed source from surrounding natural forests Resco de Dios et al 2005). …”

To restore nonwooded stands dominated by dwarf bamboo species (Sasa kurilensis or S. senanensis) into forests, mechanical soil scarification has been applied in northern Japan since the 1960s. The treatment is followed both by natural regeneration and artificial planting. In this study, we quantified the total carbon stock (plants plus 0.3 m depth of soil) of these stands over 35-year age-sequences.The natural regeneration stands were gradually dominated by Betula ermanii. The carbon stock increased linearly to 215.1 ± 35.2 Mg C ha -1 for 37-year-old stand formerly dominated by S.kurilensis, and 181.1 ± 29.8 Mg C ha -1 for 34-year-old stand formerly dominated by S. senanensis.The latter was similar to that of a Picea glehnii plantation, formerly dominated by S. senanensis, with comparable stand age (160.3 ± 6.7 Mg C ha -1 for 35-year-old stands). Although the carbon stock in plants quickly offset the untreated level, that in the soil remained depressed even in the older stands. This resulted in small differences in carbon stock of these stands with untreated dwarf bamboo stands. We conclude that natural regeneration following scarification could be a prime option for carbon sink management in the region. However, we should take a long rotation period (i.e. > 50-year) to ensure a carbon sink state. A potential of further improvements of the practice, including that reduce intensity of soil disturbance, was presented.
