Goals of the intervention
- Improve the air quality in Sofia by bringing fresh air from the mountain to the city
- Absorb carbon dioxide in order to mitigate climate change
- Reduce noise pollution
- Ameliorate the soils
- Promote biodiversity

Quantitative targets
Quantitative targets mentioned in the planning stage:
- Plant between 100 and >300 trees (depending on whether they will receive support from the municipality or not)
- Provide the foundation for a subsequent campaign for planting 1 million trees in Sofia
- 1 tonne of carbon dioxide captured per tree over the lifetime of the trees is expected
(Ref. 1; Ref. 2; Ref. 5).
Quantitative targets mentioned in phase as of 2019:
- plant a total of 125,000 trees (Ref 8)
- Plant between 100 and >300 trees (depending on whether they will receive support from the municipality or not)
- Provide the foundation for a subsequent campaign for planting 1 million trees in Sofia
- 1 tonne of carbon dioxide captured per tree over the lifetime of the trees is expected
(Ref. 1; Ref. 2; Ref. 5).

Sustainability challenge(s) addressed
Climate change adaptation: What were the goals of the NBS?
Climate change adaptation: What activities are implemented to realize the conservation goals and targets?
What types of restoration goals are / were defined for the NBS intervention?
What activities are implemented to realize the restoration goals and targets?
Implementation activities
- Planting trees on a neglected urban land in order to restore the natural connection between the mountain and the city
- Collecting donations for buying the land, prepare the soil, buy and plant the trees, and care after the trees in the first year following their planting
- Offering donors to have their own tree and use it for whatever they like - e.g. put a label on it, a swing, etc.
(Ref. 1; Ref. 2)
Regarding the status of the project: The project started on March 24th 2018., with planted saplings taking place in three phases (2018). The most recent reference (2019) mentions "Our goal is to plant over 125,000 aromatic trees in this area" (Ref 8), so the project seems to be ongoing.
