“…In other cases, the knowledge of the best phenological stage to manage acacias improves the effectiveness of management actions. For instance, basal cuttings of young A. mearnsii individuals (≤7 years) should be preferably done in non-growing periods to diminish sprouting (Perrando and Corder 2006). On the other hand, similar management actions may yield different results at different locations due to the specific site conditions and life history traits.…”

Key message The above-and belowground impacts due to Acacia invasions have been described in detail over the last 25 years. Future research should focus on the early detection and prevention of new Acacia introductions and on a cost-effective and sustainable management of the novel ecosystems resulting from invasions.• Context Invasive alien plants (IAPs) strongly alter ecosystems reducing biodiversity, modifying ecosystem services and increasing negative impacts at social and economic level. Among invasive taxa, Acacia is a highly problematic genus worldwide. In fact, almost 500 papers have been published on several aspects of Acacia invasions for the last 25 years.• Aims We aim at reviewing the current knowledge on the consequences of the invasion by Acacia genus in Mediterranean ecosystems. We also collect and propose different approaches for the management and recovery of invaded areas and suggest future perspectives on Acacia research. • Methods We compile, summarise and discuss recent findings on physicochemical, ecological, microbiological and socioeconomic aspects of invasion related to Australian acacias (Acacia dealbata, Acacia longifolia, Acacia mearnsii, Acacia saligna and Acacia melanoxylon) focusing on Mediterranean areas.• Results Acacia invasion generally entails soil physicochemical alterations and changes in microbial function and structure. Consequences such as the decreased biodiversity, altered ecosystem structure, larger seed banks dominated by invasive species, new biotrophic relationships or alterations in water availability and fire regimes suggest that acacias are locally creating novel ecosystems.• Conclusions Forecasting invasions, modelling and managing ecosystems dominated by acacias are challenging tasks that should be addressed in the future, since climatic conditions and intensification in land uses are increasing the likelihood of Acacia invasions in Mediterranean areas. Unsuccessful management actions suggest that restoration should be meticulously monitored, but the magnitude of invasion or the inconsistency of economic investment indicate that eradication is often unfeasible. Alternatively, novel integrative and cost-effective solutions including the collaboration of society, politicians and stakeholders are necessary to prevent new introductions and achieve sustainable control of acacias. There is a growing interest in applied research on the valorisation or novel uses for acacias and their residues that result in economic benefits.

“…There was also a positive correlation between the means of the tiller CAB and mean height of the tiller, indicating that the bigger the tiller CAB, the larger their height. According to Perrando and Corder (2006), the correlation between CAB and the number of tillers can be justified by the presence of basal and adventitious buds resulting from the increase of the peripheral region of the wood, thus aiding regrowth. The correlation found between the variables of stump CAB and the number of tillers may also be related to the nutritional reserve in both the stumps and the roots, which may allow for an amount of carbohydrates needed for each stump to regrow.…”

ResumoObjetivou-se avaliar a rebrota e reconstituir a biomassa arbustiva-arbórea a partir das cepas em uma área de Caatinga sob manejo florestal em Floresta-PE, Brasil. Dois anos após intervenção em 18 parcelas foram medidas as circunferências e alturas das cepas e dos perfilhos. Foi avaliada a influência do diâmetro e da altura da cepa na brotação das espécies. Em uma área próxima e sem intervenção, foram tomados dados de diâmetro a altura da base e do peito para reconstituição da biomassa explorada. Verificou-se que Poincianella bracteosa e Aspidosperma pyrifolium emitiram maior número de perfilhos nas cepas com circunferência maior que 30 cm, mas sem influência da altura da cepa. A biomassa média estimada (17186,16 kg ha -1 ) foi similar a áreas submetidas à intervenção antrópica e a sua reconstituição pode ser uma ferramenta auxiliar na para órgãos ambientais na fiscalização de desmatamento ilegal. Palavras-chave: corte raso, regeneração natural, semiárido AbstractThis study aimed to evaluate stump regrowth and estimate the reconstitution of shrub-tree biomass from the stumps in an area of Caatinga under forest management in Floresta-PE, Brazil. The circumferences and heights of the stump and sprouts were measured two years after an intervention on 18 plots. The influence of the stump diameter and its height on the sprouting ability of the species was evaluated. Data was taken in the next area without intervention in order to estimate the diameter at breast height for reconstitution of the exploited biomass. We found that the tillering for Poincianella bracteosa and Aspidosperma pyrifolium was influenced by the size of the circumference, but not by the stump height. The average estimated biomass (17186.16 kg ha -1 ) was similar to other areas also subject to human intervention, and its reconstitution can be an auxiliary tool for monitoring illegal deforestation by environmental agencies.

“…Other potential causes of mortality include time of year, the height of the cut (BORGES JUNIOR et al, 2004;PERRANDO and CORDER, 2006) and the age of the trees (PERRANDO and CORDER, 2006;HARTMANN et al, 2011). However, clarifying the causes of shooting failure is not an easy task, given the many factors that may be involved (STURION and HIGA, 1997).…”

VEGETATIVE RESCUE AND CUTTINGS PROPAGATION OF Araucaria angustifolia (Bertol.) Kuntze

-Brazilian pine or araucaria (Araucaria angustifolia) is a coniferous tree with great economic, social and environmental importance in southern Brazil, being exploited for both wood production and for its edible pine nuts. However, no efficient cloning techniques are available and, therefore, the purpose of this study was to evaluate the effectiveness of vegetative rescue methods for cuttings propagation of the species. Shoots/cuttings were generated in two ways: 26 years old trees underwent coppicing and 20 years old trees had the primary branches on the upper third of crown pruned at 2, 20 and 50 cm from the main trunk. Orthotropic shoots were rooted after application of indole-3-butyric acid (IBA) at 0, 2, 4 and 6 g.L -1. Coppicing produced 47 cuttings per plant with 90% orthotropic shoots, while pruning resulted in 182 cuttings per plant with 44% orthotropic shoots. Rooting success indexes were low with no influence of IBA, although they are slightly superior to the ones available in the literature for the species, ranging from 12 to 30% for the coppice shoots and from 0 to 28% for the branches shoots. We conclude that both vegetative rescue techniques are viable and have potentially important applications. Coppicing is recommended for the propagation aiming the production of wood, while shoots derived from the side branches of the crown are more appropriate for seeds orchards formation.Keywords: Brazilian pine; Cutting propagation; Clonal forestry.
