Seeds are raised in local nurseries
All trees start their life in local nurseries in Tanzania, run by our partners.
Here, species are selected that:
- Are adapted to local conditions
- Support biodiversity
- Can thrive long term without artificial support
Tree planting focused on long-term development
We do not plant trees as symbolism, but as a long-term effort focused on biodiversity and local communities
From seed to forest – the process step by step
Planting in dedicated areas
When the trees are strong enough, they are planted in selected areas.
We ensure that:
- The soil is suitable
- The local community is involved
- There are clear agreements on protection and care
We do not plant monocultures, but varied forest systems.
Care, monitoring and replanting
All trees planted through Treesy are:
- Cared for and monitored at least 4 times per year
- For a minimum of 3 years after planting
- Replanted at no extra cost if they do not survive the first three years
Tree planting at Treesy does not stop the day the tree goes into the ground.
Varied forest systems
We do not plant monocultures, but create living, resilient forests with room for biodiversity.
Three main groups of trees – balance instead of plantations
We work with three main groups of trees. The groups describe their role in the planting:
Canopy trees
Large canopy trees that:
- Build high biomass
- Store large amounts of CO₂ over time
- Create shade and stability in the forest
Trees for biodiversity
Native species that:
- Provide habitats for birds, insects and mammals
- Strengthen ecosystem resilience
- Maintain natural balance
Fruit trees
Productive trees that:
- Provide access to food
- Produce fruit that can be sold locally
- Create economic incentives for protection
Fruit trees, canopy trees and trees chosen for biodiversity play different roles in a planting area.
The 19 tree species in our planting plan
The planting plan for Tanzania’s Usambara Mountains includes seven fruit tree species, six agroforestry species and six species for restoration.
Fruit trees
- Persea americana
- Chrysophyllum cainito
- Citrus limon
- Pyrus communis
- Prunus persica
- Prunus domestica
- Syzygium cumini
Agroforestry trees
- Grevillea robusta
- Markhamia lutea
- Albizia gummifera
- Bridelia micrantha
- Japanese camphor
- Acrocupus
Trees for restoration
- Podocarpus usambarensis
- Rauvolfia caffra
- Prunus africana
- Croton megalocarpus
- Tabernaemontana usambarensis
- Cordia africana
Every tree is individually registered and geotagged
Once your tree is planted, you can see its unique ID and GPS location in your Treesy account. If it does not survive its first three years, we replant it at no extra cost.

Why do we plant in Tanzania?
Growth and CO₂ uptake
Tree growth depends on:
- Species
- Growing conditions
- Care and survival
Price per tree
Our calculator shows:
- Tree count
- Price per tree
- Total price for your selection
Social impact
Local partners carry out the work in Tanzania:
- Planting trees
- Caring for the plantings
- Replanting in the first three years
Local presence and responsibility
One of Treesy's co-owners lives in Tanzania. That means we:
- Are on the ground ourselves
- Participate in planting and monitoring
- Have direct dialogue with our partners
Instead, we prioritize transparency, documentation and physical presence.
What are carbon, CO₂ and CO₂e?
Carbon
An element that is the building block of all living material, including trees.
CO₂ (carbon dioxide)
A gas formed when carbon binds with oxygen. CO₂ is what trees absorb through photosynthesis.
CO₂e (CO₂ equivalents)
A unit of measurement that combines all greenhouse gases, such as methane and nitrous oxide, into one common metric.
How do we calculate?
Our calculations
Our estimates are based on:
- Consumption-based averages from CONCITO (approx. 13 tons CO₂e per Dane per year)
- Treesy’s calculation assumption about CO₂ uptake
Our calculation assumes 100 kg CO₂ per tree over its lifetime.
13,000 kg divided by 100 kg gives a contribution of 130 trees. Uptake is gradual and depends on species, location, care and survival. The assumption determines the contribution; it is not measured uptake or a guaranteed minimum. The model does not yet have a validated time horizon. For planning, we expect around 25% to need replanting in the first three years. Replacement trees start growing from the beginning.
