Maintenance of BJF restoration sites: taking good care of our growing native trees

By News Home

The end of the planting season is also the time to take care of the small (and not so small) trees that are growing in our restoration sites. After planting many seedlings and seeds over the last rainy season, our field team will now focus their efforts on maintenance.

Maintenance consists of: removing invasive plants that eventually compete with our planted trees, carrying out complementary fertilization and guaranteeing that the fences and forest firebreaks (aceiros) surrounding the project areas stay functional. These activities are realized every four months, or until full canopy closure of the forest, and can take up to three years.

Why is it important to maintain our growing seedlings?

Maintenance is one of the 17 steps in the Black Jaguar Foundation’s Cycle of Ecological Restoration. That’s how we ensure that the seedlings planted can grow into resilient trees along the Araguaia Biodiversity Corridor. 

One of the activities carried out during the maintenance process is managing invasive exotic grasses, to prevent competition with native tree seedlings and plants.

According to our Project Coordinator, Dimitrio Schievenin, the maintenance phase is just as important as the planting itself. “One of the biggest reasons for the failure of restoration projects throughout Brazil is precisely the lack of maintenance,” he explains.  

Because of this, we closely monitor the growth of our seedlings, performing maintenance whenever necessary, and allowing biodiversity to gradually return to the areas where we operate.

Biodiversity Update: Planting even more native tree species

By News Home

Each planting season, our team learns even more about all the different native species we need in each restoration site, allowing us to improve the return of healthy ecosystems. See how we are contributing to enriching the region’s biodiversity.

Variety of native species planted in BJF restoration sites

Currently, we use about 73 different species of trees in our restoration projects! Among these, some are adapted to flooded soils, while others thrive in drier regions. Depending on the technique used in the restoration site, the key species planted differ.  Have a look below to find out more about the variety of species in our restoration sites: 

Direct Seeding
Planting Seedlings

In the planting stage, we divide the different species of seedlings into two groups: canopy and diversity. Both groups are then planted in the restoration site. Canopy trees are fast-growing and serve to provide shade to the area and rebuild the forest structure. On the other hand, diversity trees grow more slowly and should be planted in between the canopy seedlings.  

This variety of species furthers the success and quality of our restoration sites and increases biodiversity in the Amazon and Cerrado biomes!

One of the stars of this planting season and many other highlights…

By News Home

Our latest planting season was full of achievements, challenges, and learning opportunities. With many positive results, we have selected some of our favourite highlights to share with you today!

Meet the Star of this Planting Season: the Sumaúma tree

Over the 2022-2023 planting season, the Black Jaguar Foundation team had the opportunity to plant the Sumaúma tree for the second time since the start of our ecological restoration efforts.

Its incredibly positive results have made it the star of this season and ensured that it will remain a key member of our operations for years to come! Sumaúma can grow incredibly fast and is one of the largest trees in the Amazon – able to reach up to 50 meters in height and 2 meters in diameter.

See its growth for yourself! The image below shows our field supervisor Taiwan next to 6 months young Sumaúma tree. Can you see that it is already bigger than him? We can’t wait for our trees to get as big as the one on the image to the right…

We are excited to see these beautiful trees grow into healthy forests in the years to come!

The Sumaúma tree is considered a mother tree for “varzea” forests, which are often forests present along rivers that are susceptible to floods. This tree species is typically found in tropical regions and develops well under direct sunlight.

Despite the Sumaúma species’ fast-growing nature, during its first 3 years of growth, it is still not very good at creating shade for ecological restoration. Therefore, we plant it together with species that can provide this shade early on, like the Cafezinho species. Creating shade is important because it causes the temperature of the soil to drop, which prevents invasive grasses from growing. These invasive grasses compete with the native trees that we plant and prevent them from growing. Therefore, by planting trees like Sumaúma together with other fast growing trees like Cafezinho, we are helping its growth and also ensuring greater biodiversity in the region! 

Scaling up on Natural Regeneration as a method of ecological restoration

30 of the many hectares planted this season were restored using natural regeneration. We hope to use this method much more in the future and take advantage of the full potential of the region.

Have a look at the video below, and understand how the BJF carries out natural regeneration:
More trees, more life!

The number of trees planted in this rainy season was higher than for any of our past rainy seasons yet. It is very exciting for us to see these numbers grow together with our operations and team!

Have a look at some of our youngest trees, planted in December last year:
What are we doing now?

We have reached the end of the planting season and our field team will continue to carry out maintenance and monitoring activities for our planted seedlings! This means that you can expect many updates on the growth of our trees in the coming time – keep an eye on our social media channels.

The maintenance process in crucial is ensuring the health of our planted trees and involves the irrigation of areas where we planted trees during the last rainy season, and removing invasive grasses, among other activities.

For the next planting season…

We will continue to plant lots of Sumaúma trees together with many other species that are native to the Araguaia region.

The BJF team has already started defining the three clusters of farms where we will carry out ecological restoration during the 2023-2024 planting season. By working in clusters, we are able to define our plan the most efficient way, optimising our logistics and labour force.

Our achievements were made possible by the vital support of our BJF partners. Join us by becoming one of the First 600 sponsors to realise the Araguaia Biodiversity Corridor.
