Eucalyptus is an arboreal species native to Australia and one of the most efficient in terms of CO2 sequestration.
In fact, eucalyptus trees if planted in regions with high rainfall and high photoperiod have a very rapid growth and consequently a sequestration rate among the highest in the world.
The main benefits of reforesting degraded areas with this species are:
- Maximum CO2 absorption: In Brazil, thanks to a greater photoperiod and abundant rainfall, eucalyptus has a faster growth and therefore a very high efficiency in the sequestration of CO2.
- High oxygen production: Thanks to chlorophyll photosynthesis, plants have the ability to transform CO2 e H2O into O2 and glucose, according to the following equation:
More glucose molecules form cellulose, the main component of wood. Even eucalyptus in a tropical environment captures CO2, but it does so with an efficiency 5 times higher than tree species in temperate areas.
- Less water consumption than other species: Eucalyptus water use is 306 liters / kg of total biomass, which is one of the lowest when compared to tree species such as oaks (400 liters / kg), and crops agricultural crops such as corn (1,000 liters / kg) and cotton (3,200 liters / kg).
- Low need for nutrients from the soil: For their development, plants need nitrogen, phosphorus and potassium (NPK). Eucalyptus trees have one of the lowest requirement rates with 4.8 (kg / hectare / year) of nitrogen, 1.3 of phosphorus and 6 of potassium. Which is inferior to that of other species such as poplar or willow.
- Does not cause drying of the soil: Eucalyptus species have a root depth of between 0.5 and 1.5 meters, their root system is more specifically adapted to utilizing soil moisture fueled by precipitation from the upper soil profile rather than from the aquifer to a considerable depth. For this reason, the species contributes to not drying out the soil.
- It has a low flammability rate: Unfortunately, forest fires are still a present phenomenon in Brazil. Eucalyptus trees have one of the lowest fuel load parameters, as well as a low flame height, which allows for better control of fires if necessary.
- Protects biodiversity: The eucalyptus trees planted in our projects act as biological corridors that allow to reconnect the native forest of the Cerrado area with the new reforested area, giving the animals an area of refuge and protection.
