In soil with Eucalyptus sp., this greater root biomass stock may be directly linked to the size of the forest and its ability to maintain organic matter in the soil for longer time due to its high lignin content and high C/ N ratio (Klug et al, 2020). Ribeiro et al, (2017) found root biomass stock values close to those found in this work in eucalyptus area, with average value close to 2.00 mg ha -1 .…”

Studies on the importance of root biomass and the effects that changes in vegetation coverage cause on carbon amount and stock are scarce, especially in the cerrado biome. Taking into account the scarcity of information about root biomass estimates, this work aimed to quantify root biomass under different land uses and native cerrado in Tocantins, Brazil. The research was conducted in different land uses: agriculture, pasture, eucalyptus and control with native cerrado forest. Six trenches with dimensions of 70 x 70 cm were opened and root biomass was collected at depths of 0-10, 10-20, 20-30, 30-40 and 40-50 cm. With the aid of a sieve, root biomass was collected and separated into fine and coarse roots. The amounts of fine and coarse root biomass showed the highest mean values of 7.7 and 12.9 g, respectively, in the eucalyptus area. Root biomass stocks were higher in the eucalyptus area, with maximum values above 3.68 Mg ha-1. Root biomass amounts and stocks were greater in eucalyptus areas, since forest areas, whether planted or native, manage to keep the environment in balance due to their long-term cycles, greater stability and low degree of disturbance.

“…França, Moreno e Callisto (2006), que estudaram a composição granulométrica e sua relação com a redução da heterogeneidade ambiental pelo uso e ocupação do solo do Rio da Velhas no estado de Minas Gerais, verificaram que as frações granulométricas mais grossas são predominantes nos ambientes classificados como conservados, enquanto que as frações mais finas são abundantes em trechos alterados. Os efeitos negativos da silvicultura sobre o substrato estão muitas vezes associados ao tipo de vegetação e ao manejo ambiental dessas áreas (WIESMEIER et al, 2009;KLUG et al, 2020). Nesse contexto, há evidências de que a preservação de espécies vegetais nativas dentro de sistemas agrários tenha papel fundamental na regulação dos processos hidrológicos e na preservação da biodiversidade local (ALTIERI, 1999).…”

Caracterização granulométrica do sedimento de nascentes tropicais em áreas plantadas com eucalipto

Nascentes são afloramentos do lençol freático que formam fluxos de água importantes na prestação de serviços ecossistêmicos, como irrigação de florestas, fornecimento de água para o consumo humano e habitat para a biota aquática. No Brasil, áreas de Mata Atlântica estão sendo gradativamente substituídas por culturas de eucalipto, alterando, comumente, a composição do substrato das nascentes. O objetivo deste estudo foi verificar se a composição granulométrica do sedimento de nascentes em áreas de floresta difere de nascentes em áreas plantadas com eucalipto. A hipótese testada foi que nascentes em áreas de eucalipto apresentam diferenças na composição granulométrica e menor porcentagem de matéria orgânica quando comparadas com nascentes em áreas de floresta. Para tanto, foi coletado o sedimento de 20 nascentes, todas pertencentes à bacia do rio Paraíba do Sul, situadas no estado de Minas Gerais, Brasil. Foi possível observar que as nascentes em áreas de floresta estiveram associadas com areia muito grossa, enquanto que aquelas em área de eucalipto estiveram associadas a partículas de granulometria mais fina. Em relação à matéria orgânica, não foi observada diferença significativa entre as duas áreas. O estudo enfatiza a importância da vegetação ciliar para mitigar potenciais impactos da silvicultura do eucalipto no sedimento das nascentes.

Global guidelines for the sustainable use of non-native trees to prevent tree invasions and mitigate their negative impacts

Sustainably managed non-native trees deliver economic and societal benefits with limited risk of spread to adjoining areas. However, some plantations have launched invasions that cause substantial damage to biodiversity and ecosystem services, while others pose substantial threats of causing such impacts. The challenge is to maximise the benefits of non-native trees, while minimising negative impacts and preserving future benefits and options. A workshop was held in 2019 to develop global guidelines for the sustainable use of non-native trees, using the Council of Europe – Bern Convention Code of Conduct on Invasive Alien Trees as a starting point. The global guidelines consist of eight recommendations: 1) Use native trees, or non-invasive non-native trees, in preference to invasive non-native trees; 2) Be aware of and comply with international, national, and regional regulations concerning non-native trees; 3) Be aware of the risk of invasion and consider global change trends; 4) Design and adopt tailored practices for plantation site selection and silvicultural management; 5) Promote and implement early detection and rapid response programmes; 6) Design and adopt tailored practices for invasive non-native tree control, habitat restoration, and for dealing with highly modified ecosystems; 7) Engage with stakeholders on the risks posed by invasive non-native trees, the impacts caused, and the options for management; and 8) Develop and support global networks, collaborative research, and information sharing on native and non-native trees. The global guidelines are a first step towards building global consensus on the precautions that should be taken when introducing and planting non-native trees. They are voluntary and are intended to complement statutory requirements under international and national legislation. The application of the global guidelines and the achievement of their goals will help to conserve forest biodiversity, ensure sustainable forestry, and contribute to the achievement of several Sustainable Development Goals of the United Nations linked with forest biodiversity.
