Royal De Heus visits the Araguaia Biodiversity Corridor!

By News Home

The Brazilian division of our partner Royal De Heus has recently visited the Araguaia Biodiversity Corridor and seen every single one of the projects that they are currently contributing to. The visit lasted three days, and included trips to the new BJF nursery, our restoration sites, and meeting the Araguaia Seed Collection Collective.

The 13 members of the Royal De Heus team that travelled with us to Santana do Araguaia showed great enthusiasm throughout the visit and even helped us plant some trees and grow seedlings in our new nursery!

They were all incredibly excited to see the project and the positive socio environmental impact that it is generating in action.

After the visit, Edmilson Ribeiro, the director of Human resources for De Heus Brasil, shared with us the following words:

“We cannot find the words to describe how happy we are with all that we saw last week. We feel incredibly proud of this partnership and the positive impact on nature that we are promoting. Simply amazing”. 

We are incredibly touched by these warm words, and grateful for all of the support that Royal De Heus has provided over the years!


De Heus was once of our greatest supporters in building the new BJF nursery, which will have the capacity to grow 500 thousand native tree seedlings annually! That’s why we decided to start our tour of the Araguaia Biodiversity Corridor with a symbolic inauguration of the BJF nursery.

In the following day, our nursery team, led by our seed production analyst Norivânia Diniz, walked the De Heus team through some of the main activities conducted in the nursery and provided an explanation of how we grow healthy seedlings to become resilient trees.

We also organised some more practical activities, where our partners got their hands dirty, helped us germinate many seeds, and even planted their own trees!



In the afternoon, we visited some the areas being restored in the Santa Fé farm and our field coordinator, Carlos Eduardo Oliveira, explained the different planting techniques currently being used in different areas. We could already see significant growth of native vegetation planted 12 and 24 months ago!

Throughout the planting activities, the De Heus team also saw some of the biodiversity present in the region and was inspired by all of the beauty that nature provides.




During the dry season, the Araguaia region is prone to forest fires. This makes fire prevention and control incredibly important.  De Heus is aware of this, and therefore supported us in creating Caseara’s first fire brigade!

We were able to visit the fire brigade – which is already in motion and considered to be one of the most active brigades in the region – present our partners to the volunteer fire fighters, and speak to Paulo Roberto, Caseara’s secretary of environment and tourism.

It was inspiring to see the brigade in action, working to contain fires. A big thank you to De Heus for making this possible!




The Araguaia Seed collection collective is another one of our projects supported by De Heus, which will have a massive impact on this and in future planting seasons!

Despite this being a recently established initiative, the De Heus team was already able  to collect seeds, participate in the first purchases of seeds, and talk to some of our seed collectors!

Our longstanding partnership with De Heus

With the global demand for food on the rise, feeding the planet while safeguarding our ecosystems is an ever-growing challenge.  

Our longstanding partner Royal De Heus is working to help farmers produce food more efficiently, in a way that safeguards natural resources as much as possible. That’s why they have chosen to support the Black Jaguar Foundation in realising the Araguaia Biodiversity Corridor!  

On August 17 2021 De Heus Animal Nutrition signed a long-term partnership with the Black Jaguar Foundation to support our efforts in realising one of the longest nature corridors on earth: The Araguaia Biodiversity Corridor.  

We are incredibly grateful to De Heus for all of their support. Thanks to them and many of our other wonderful partners, we have been able to make great progress with the new BJF nursery, collect many seeds with the Araguaia Seed Collection Collective, and train capable firefighters to protect our planted trees!  

 This partnership will certainly play an important role in bringing together agriculture and environment! We are excited to see the ever-growing trust placed on our organisation, and hopeful for all the milestones that will certainly come with it.

The Importance of native vegetation in keeping the Araguaia River alive

By News Home

The Araguaia Biodiversity Corridor will consist of strips of ecologically restored land that connect isolated ‘islands’ of pristine and intact nature. In doing so, it also contributes to keeping the Araguaia River alive, as a lot depends on the river. Not only for fresh water, but also for transport, species in and alongside the river and as a source of cooling amongst many other important ecosystem services.

How does native vegetation (trees!) keep rivers healthy?

The vegetation that is found on river margins, often referred to as riparian vegetation, is vital for the preservation of different processes that occur naturally in and around rivers. Such processes include:  

  1. The purification of water 

    Did you know that trees help to filter water? They do this by first absorbing the water through their leaves, and then releasing it as 1) water vapor and 2) through their roots. In absorbing rainwater, trees also absorb the nutrients that may have been picked up from excess fertilizer or animal waste. In doing so, they lower the amount of pollutants in our rivers.

  2.  Providing shade and shelter to aquatic animals  

    By providing shade during periods with high temperatures, trees help to reduce the water temperature, and keep oxygen in the water which helps preserve aquatic organisms.  

  3. Stabilising river banks and reducing bank erosion. 

    Erosion and sedimentation are natural processes, but can also generate problems for the river’s health. The presence of too much sediment in the water reduces water quality and can lower the river’s ability to flow, meaning that the quantity of water present can also decrease.  By stabilising river banks, trees reduce erosion and limit the amount of sediments that fall into the river.  

Why is the Araguaia region important for our planet?

The Araguaia and Bananal lowland regions island regions were identified by ministry of environment as priority areas for conservation due to their high biodiversity and vast flooding regions. Also the Cerrado and Amazon are inseparable connected by soil, air and the rivers.

At Black Jaguar Foundation all our efforts are to realise the Araguaia Biodiversity Corridor because we believe that it truly has the size to make a difference. Would you like to join our mission of hope and action? Donate a tree here 

Training the Araguaia Seed Collection Collective

By News Home

In preparation for this planting season, our team has been working hard to collect seeds with the Araguaia Seed Collection Collective, led by Laís D’Ísep dos Santos.  

So far, we have already bought seeds of around 11 different native tree species! The seeds we have purchased are mainly caju (cashew) seeds, since there is an abundance of these in the settlements that are near our restoration sites.  

Currently, we have 18 participants who are actively collecting seeds and over 100 other people recently received the first two modules of seed collective training.

We plan to complete this first cycle, consisting of four modules of training sessions, by the end of this year.  

The Seed Collection Collective will focus on the following native species this year:

Popular name   Scientific name  
Aroeira verdadeira  Astronium urundeuva 
Baru  Dipteryx alata 
Cashew  Anacardium occidentale 
Copaíba  Copaifera spp. 
Embaúba  Cecropia pachystachya 
Favela/orelha  Enterolobium schomburgkii 
Guarita  Astronium fraxinifolium 
Jatobá  Hymenaea courbaril 
Melzinho/mamoninha do mato  Mabea spp. 
Monjoleiro  Senegalia polyphylla 
Mutamba  Guazuma ulmifolia 
Pente-de-macaco  Apeiba timbourbou 
Tamboril/orelha  Enterolobium timbouva 
Urucum plantado  Bixa orellana
Xixá  Sterculia spp. 

Have a look at the first two modules for our seed collective training below!

Accelerating seedling production in our large new nursery

By News Home

With the rainy season approaching fast, we have intensified seedling production in our large new nursery! 

During the past weeks, we have germinated many different species, and are happy to announce that the seeds we sowed between June and July have already grown enough to be transported to the next phase of the seedling production process. These seedlings have just moved to our open sun site area, so that they can get used to field conditions and become resilient trees. 


Watch our forest engineer Dimitrio Schievenin explain our seedling production process

In this first stage, the focus is on the production of species that are able to grow in periodically flooded regions. For this reason, we are focussing our production on species with these characteristics, including ingá, guarandi and jequitibá vermelho, among others 

These species will become part of the first stage of our planting season, which will begin in October. Nevertheless, our second batch of seedlings will include a wider range of species that are native to the region.  

While the seeds develop, the seedlings that were sowed by our nursery team between June and July have already grown enough to move from our covered, inside nursery, to the open sun site areas. In this stage,  which is often referred to as acclimatisation, they are exposed to field conditions so that they can become resilient and grow.  

These seedlings will be planted in our restoration sites between October and November. We are very excited to see so many of our seedlings grow into healthy forests in the Araguaia Biodiversity Corridor! 

Moving towards more sustainable seedling production

At  the Black Jaguar Foundation, we strive to be as environmentally conscious as possible while carrying out our ecological restoration methods!

One of our most recent developments has been adjusting the way we grow and transport seedlings. Instead of using plastic bags, the BJF team now uses re-usable tubes.  

 One of the biggest benefits of this is the fact the these tubes can be reused with each poduction cycle – for up to 10 years. 

Another benefit is that these tubes take up a lot less space, which allows us to produce more seedlings in our nursery, using less soil. In other words, more seedlings for the coming planting season!  

All of these updates, together with our ever-increasing work rhythm, indicate that the coming months will be full of wonderful achievements. None of this would be possible without your support, so thank you! We hope you continue following our journey of ecological restoration.   

Taking care of our planted trees to ensure healthy forests

By News Home

As the coming planting season approaches, we cannot forget about the trees we planted in the past planting seasons! 

To take care of our planted trees, we carry out maintenance throughout the year, regardless of the season. Nevertheless, we choose to concentrate our efforts during specific periods. We started this process a little bit earlier this year, as we are completing our first million trees.  

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.  


Have a look at some of our team carrying out maintenance below:

 We also  need to ensure an environment where our planted trees are able to grow and contribute to heathy and functioning ecosystems. In many cases, this means that we need to build fences.  


Building Fences

Building fences is crucial to the protection of recently restored areas. Fences are needed in ecologically restored areas that are near cattle, to prevent these from eating or stepping on the young seedlings. This is a vital step in our cycle of ecological restoration, helping us to protect our young seedlings and ensure their growth. 

All of this care is vital in ensuring healthy forests! Would you like to become part of our grand mission of hope? Donate a tree here

Two years ago, we planted many native trees, of only 30 cm in height. Now, many of these trees have grown to over four meters high!

We have also been finding regenerating species that were not planted by us, which is one of the best signs that our ecological restoration efforts are working. 

Watch our forest engineer Dimitrio Schievenin explain the wonderful growth of our trees:

Walk through this 1.5 year old restoration site with our community outreach coordinator Joël Boele!

What else do healthy forests have? Seeds!! We are happy to share that many seeds  have also been growing on our trees. 

Have a look at the seeds growing on our trees!

None of this would have been possible without all of the support we receive from our wonderful sponsor partners. Thank you for your commitment to realising the Araguaia Biodiversity Corridor.  Below, please see a video message from our initiator Ben Valks, straight from the field!

These healthy and resilient trees, growing at the heart of the Araguaia Biodiversity Corridor, are only the start. It motivates us to see how far our restoration efforts have come, and we look forward to planting many more trees!  

Our team was invited to lecture at the Federal University of Southern and Southeastern Pará!

By News Home

Last month, Our field team participated in the second set of meetings organised by  the Federal university of South and Southwest Pará, regarding education and research projects. 

During the event, Carlos Eduardo Oliveira (Field Coordinator), Norivânia Diniz (Seedling production analyst) and Laís D’Isep (Seed production analyst) presented the Black Jaguar Foundation’s mission of ecological restoration to over 50 university students.  

The main theme of the event was: “Education and social responsibility: building values of citizenship and sustainability”.  


The UN’s sustainable development goals are global treaty signed by 193 member states in 2015. It is made up of 17 ambitious and interconnected objectives, spread out into 169 goals, focussed on overcoming the main challenges of international development.  

 In her lecture, Laís D’isep, our seed production analyst, talked about how collecting seeds can help Santana do Araguaia reach some of the sustainable development goals proposed by the UN.   


Finally, our seedling production analyst, Norivânia Diniz, dove into her routine working in the BJF nursery: from seedling production, to pros and cons of using different types of containers, to the main challenges faces in the process of seedling production! 

 Norivânia also explained the current infrastructure of our latest nursery, including new machines, what we are using them for, and how that will help with seed production. Overall, this provided a great opportunity to show university what the day-to-day of the nursery is like!  

 Here at the BJF, we believe that environmental education plays an important role in increasing community engagement in issues related to social responsibility. We are incredibly grateful for this opportunity to shape the minds of tomorrow.
