The BJF Nursery is already producing seedlings for our next planting season.

By News Home

Already with the 23/24 planting season in mind, our team is continuing to grow many seedlings in the BJF nursery. 

We are starting early this year to ensure that we are able to plant as many trees as possible in the next planting season. At the end of 2022, when we were at the peak of the 2022/2023 planting season, we started searching for native seeds of species that we did not already include in our ecological restoration activities. So far, we already have over 1500 kilograms of purchased seeds!  

Thanks to the Araguaia Seed Network and some o four partner organisations and collectives, we are always on the lookout for native species to use in our project!  

The BJF nursery at full speed  

With the seeds in our hands, we are able to start producing seedlings. To ensure the growth of these seeds, our nursery team first sowed recalcitrant seeds, including: ingá-peludo, cafezinho, sombreiro, pau-preto and cupuaçu.  

 Afterwards, the team started sowing orthodox seeds – which can be stored for longer periods of time.  

Learning with new species of seeds 

At the start of this year, our team went out in search of some more species to add to our nursery’s seedling production. We found 7 different species that grow in flooded regions of the Araguaia Region. These can be used in our ecological restoration activities and will increase the biodiversity of our restoration sites!  

Finding these new species has been a great learning opportunity for our team. Over the past months, our seedling production analyst, Norivânia Diniz, has dedicated herself to getting to know how these species behave. Norivânia is determined to improve our restoration activities and continue to produce high quality seedlings for the Araguaia Biodiversity Corridor 

The wonderful results seen in the BJF Nursery were made possible by the combined efforts of the Araguaia Seed Network, providing us with a large number of seeds, and our nursery team, who work hard to grow resilient seedlings for our restoration sites.

About The UvA-orkest J. Pzn. Sweelinck Orchestra

The oldest symphony orchestra of Amsterdam is filled with 85 inspired and enthusiastic young musicians, all students. Through the years, Sweelinck has performed multiple great works, has accompanied the greatest soloists and most importantly, brought up the musical spirit among many people, young and old. The orchestra aims to bring music to everyone, not only the common music enthusiast, but especially those who have never been to a classical music concert before.

Watch their crowd funding video below:

How does the orchestra support BJF?

Every two years, the Sweelinck orchestra leaves the Netherlands for a new country, to bring music to all people there and to enhance the team spirit within the orchestra. Such tours are very important to the development of the students and to set our musical programme in a new light.

Nevertheless, the tours also involve some travel by plane. This year, Sweelinck Orchestra will travel by train as much as possible, and compensate for their travel by planting some trees with the Black Jaguar Foundation!

How are you celebrating Mother’s Day this year? At the Black Jaguar Foundation, we know that our mothers would like nothing more than to see their kids healthy, happy and safe. Still, it does not hurt to show them some appreciation from time to time!

For Mother’s Day, we created a list of three thoughtful ways of honouring our mothers while ensuring a healthier planet for future generations:

1. Donating Trees

Give your mom the gift of life! Doesn’t that seem fitting? This gift will make for a funny anecdote and keep giving for generations to come. When you donate trees, you receive a personalised tree certificate, showing where your trees will be planted.

Your donation will contribute to a cycle of 17 steps of ecological restoration and ensure that your mother’s tree becomes resilient and grows strong in the years to come. As the trees grow, they also contribute to:

  • Increased biodiversity
  • Revitalised ecosystem services
  • Improving the livelihoods of local communities
  • Helping to mitigate climate change

A gesture your mom will certainly appreciate! Donate a Tree HERE. 

2. With a special gift by TreeLove

Celebrate the future with a present – carefully designed by TreeLove. Have a look at their beautiful array of gifts, all of which plant native trees along the Amazon’s Araguaia Biodiversity corridor. From their gorgeous necklaces to their selection of handmade sculptures by carefully chosen artists from around the world, each gift represents your personal contribution and commitment to the planet.

3. By sharing the beautiful gesture you made for your mom on social media! 

Nothing speaks louder than honouring the moments you have shared together. So, how about sharing the beautiful gesture you made for your mom? This ways you can celebrate Mother’s while promoting biodiversity in the Amazon Rainforest and Cerrado Savanna!

We prepared instagrammable certificates for you to download and share! Find them by clicking on the links below:

How does ecological restoration of non-forest ecosystems differ from forest ecosystems?

By News Home
The above image shows soil preparation of one of our restoration sites

After receiving many questions on the topic, our Project Coordinator, Dimitrio Schievenin wrote a blogpost for the BJF about how the ecological restoration of forest ecosystems differs from non-forest ecosystems including grasslands. Dimitrio is a forest engineer with a Masters in Forest Science from São Paulo State University and a bachelor’s degree in Forest Engineering from São Carlos Federal University. We are proud to have him coordinating, organising, and implementing the ecological restoration that is needed to realise the Araguaia Biodiversity Corridor! 

 Ecological restoration is often associated with planting native trees. However, not all natural ecosystems are forests – some do not even have trees. Therefore, all ecological restoration must consider the composition and structure of the original ecosystem in the planning and implementation of projects.  

Map illustrating the Araguaia Biodiversity Corridor

The Araguaia Biodiversity Corridor covers the two largest biomes in Brazil: the Amazon Rainforest and the Cerrado Savanna. The Amazon consists mainly of forest environments which vary depending on flooding, seasonality, and type of soil. This is not the case for the Cerrado Savanna. Though this biome does have many forested areas, it consists mainly of open patches of land that may or may not contain trees. The so-called “typical Cerrado” (cerrado strictu-sensu) is made up of smaller trees, spaced to the point that they are not able to form shade over the ground with their leaves, and have full canopy closure, but do contain bushes and native grasses.  

 There are also grasslands, which may not contain any trees at all. All these native non-forest environments play a very important role in ensuring ecosystem services. This is especially true when it comes to replenishing groundwater and enabling biodiversity to thrive. When there is a need to restore an ecosystem that was originally not forested, planting trees may not be the best strategy, as it modifies the environment and harms the ecosystem services and fauna that do best in open areas. In this case, the reintroduction of native grasses and shrubs, as well as the control of invasive exotic grasses, is what could really help in the recovery of the ecosystem. 

 So far, the Black Jaguar Foundation’s efforts have focused on the central and northern portion of the Araguaia Biodiversity Corridor, which has mostly forests. Nevertheless, once we start restoring savannah and grassland areas, we will of course be sure to use the best practices and always take into account the area’s previous vegetation. After all, the reason we are carrying out ecological restoration is to revitalize our ecosystems for the long term.

BJF team demonstrates the Araguaia Biodiversity Corridor!

By News Home

At the start of this month, the BJF team presented the Araguaia Biodiversity Corridor to some of our loyal sponsor partners! Over the course of three days, we organized visits to the BJF nursery, ecological restoration sites, and seed collection activities with the Araguaia Seed network. We even collected seeds in flooded areas, from a canoe! 

Amazing, isn’t it? Check out the “logbook” that we have prepared for you:

During our first day in Santana do Araguaia (PA), we visited the BJF Nursery, which is already full of seedlings for the next planting season! 

At the nursery, our Seedling Production Analyst, Norivânia Diniz, explained the entire process of seedling production. Afterwards, our visitors got their hands dirty by carrying out the direct seeding of andiroba and sombrero seeds, and then transplanting annatto and guanandi seedlings from the sand beds where they were originally sowed, to tubes. 

See the visit in action:

In the morning of the following day, we visited our ecological restoration sites on one of our partner farms! We visited an area where we carried out ecological restoration just 11 months ago. See how our trees have grown 

Our visitors took the opportunity to plant some trees themselves:  

During the afternoon, our Seed Production Analyst, Laís D’Ísep, talked about the Araguaia Seed Network and the positive impact that it is generating for the communities that live in the region. 

At the end of the day, our Articulation Coordinator, Marcelle Grumberg, answered our parner’s questions regarding the Brazilian Forest Code and explained how the Black Jaguar Foundation works with landowners in the region.

Meeting the Araguaia Seed Network

On the last day of the trip, we were excited to introduce our loyal BJF partners to members of the Araguaia Seed Network. Our Seed Network started as a means of providing seeds for our project of ecological restoration is now making a real difference for communities living in the Araguaia region! One of the families that is currently collecting seeds for Black Jaguar Foundation invited us to their house, which borders the Araguaia River. We collected seeds in surrounding areas however needed a canoe to do so given that many sites flooded during the rainy season.  

After fully immersing themselves in the Araguaia Biodiversity Corridor, our BJF sponsors left with a very clear picture of the socio-environmental impact that our project is promoting in the region. They were also very please to see how much we have grown in past years.  

We are very proud of all that we have seen in the past few days and hope that, after reading this account of their visit, you feel closer to our mission as well!

BJF partners with local government in Pará to restore native vegetation!

By News Home

A big thank you to the state of Pará’s Secretary of Environment and sustainability for inviting the Black Jaguar Foundation to become part of the working group that will be responsible for building Para’s plan to restore native vegetation!  

The plan, which is part of the program “Amazônia Agora” (PEAA), aims to restore 5.4 million hectares in Pará until 2030. It will be a collaborative effort, to be delivered at this year’s UN Climate Conference (COP 28). This will further the goal of neutralising Greenhouse Gas (GHG) emissions by the year 2036, as outlined in the PEAA plan.

The Working Group will be responsible for holding meetings, identifying obstacles and opportunities, mapping ongoing restoration activities in the state of Pará, promoting workshops for building the state of Pará’s restoration activities, among many other activities.

Around 50 institutions are currently participating in this working group, including governmental agencies, research institutions, NGOs, indigenous peoples, quilombolas, and traditional communities. 

The Black Jaguar Foundation was present in the working group’s inauguration cerimony

On the 17th of March, part of our landraising team, led by Marcelle Grumberg, traveled to Belém to represent the BJF at the opening ceremony of the Working Group. 

Have a look some pictures of our team with Raul Protázio Romão, Pará’s Secretary of Environment and sustainability (left), and Mariana Iguatemy (right) at the event:  

We are very proud to be part of a project based on dialogue between such a diverse group of people and organizations. We hope this collaboration will contribute to the creation, integration, and promotion of projects that contribute to the ecological restoration of the Earth. Additionally, we are certain that increasing restoration efforts will also benefit the local economy by providing new jobs and income

Easter tulip action in the Netherlands with Tulpen van Sam!

By News Home

In cooperation with Tulpen van Sam, based in The Netherlands, the BJF team spent the day delivering beautiful climate neutral tulips to some of our loyal BJF partners and friends. The event took place just in time for Easter and we hope the tulips brought even more joy to many family celebrations! Have a look at the smiling faces of some of our valued partners and sponsors in the image below:

We spent all day on the Tuesday leading up to Easter Weekend, some of us in a car and others on a bike, traveling around the Netherlands and into Belgium to visit our partners and sponsors.

With each visit we personally delivered beautiful bouquets of tulips, an Easter card, and a personalized letter with some updates from the field. We loved seeing the surprised faces of our unsuspecting friends, and are excited to continue this tradition for many years to come!

The tulips serve as a reminder that restoring the Araguaia Biodiversity Corridor is only possible with the continuous support of the BJF community. Would you like to join us on this mission of hope and action? Become one of the First 600 HERE.

Tulpen van Sam is a Dutch tulip and tulip bulb company and has partnered with the BJF to render the production of his tulips climate neutral. While delivering the tulips, we received many questions regarding their production. Thankfully, Sam Ruijter, owner of Tulpen van Sam, created a beautiful video-testimonial that explains this very well! Watch it below:

Our partner Tulpen van Sam has been working hard over the past six years to ensure that the production of their tulips is carbon neutral. Sam has built a smart tulip nursery that makes use of solar panels, heat pumps, and LED-lights to provide heat for the growth of his tulips without fossil fuels.

Besides these innovative advances, since 2020, Sam has also been planting trees with the Black Jaguar Foundation and helping us realize the Araguaia Biodiversity Corridor.
