Native title of the NBS intervention
Stadens träd: Policy för park och gatuträd i Göteborg
Short description of the intervention
The City of Gothenburg's policy for park and street trees was updated in 2016 and has the overarching aim to maintain and develop the ecological, historical, social and economic values of the city's trees and tree environments. Trees are described as having ecological, historical, cultural and economic values. They can provide ecosystem services such as habitat and biodiversity, air quality improvement, flood prevention, heat mitigation, recreation and aesthetic values [Ref. 1].

The policy applies to all trees in the streets, squares, and parks within the municipality but not to natural environments such as forests at the city's edge. Further, the policy is mostly relevant for municipality employees whenever they make decisions that will affect trees or tree-covered areas, such as zoning/planning and construction projects. Other actors in the city, such as private real estate or construction companies, are not required to follow the policy but are encouraged to consider it. The policy formulates sub-goals and guidances regarding the preservation of existing trees (prioritising large and old ones), the planting of new trees, the maintenance of trees, protection during construction work and finally, the taking down of trees, including compensation measures. The policy's direct effects is an expected improved management of trees within the municipal organisation. This may have further indirect benefits in the form of increased ecosystem service provision when the policy affects other projects [Ref. 1, 2].

Objectives of the intervention
Goals of the intervention
The main goal of the policy is that the City of Gothenburg should
"Maintain and develop ecological, historical, social and economical values of the city's trees and tree environments". The sub-goals in the policy are:
"1. Existing trees: Consider all values of the trees during planning which affects existing trees.
2. Planting trees: When planting new trees, choose the right tree for the right location and give the tree the pre-conditions to develop normally.
3. Tree maintenance: Care for the trees so that they are given the pre-conditions to grow normally and develop many values.
4. Protection of trees: Protect the trees from damages when construction work happens nearby.
5: Removing trees: Consider the values of trees and tree environments if trees are planned to be taken down." [Ref. 2]
Furthermore, the policy should contribute to the general sustainability goals of the city's environmental programme and some national sustainability goals [Ref. 1-2].
The "values of trees" frequently referred to in the policy are described in one of the sections, divided into ecological, historical, cultural and economic values. The values are also summarised as ecosystem services [Ref. 2].
Habitats and biodiversity conservation: What types of conservation goals are / were defined for the NBS intervention?
Habitats and biodiversity conservation: What activities are implemented to realize the conservation goals and targets?
Mental health and well-being objectives
The policy acknowledges research showing that trees contribute to reduced stress and increased wellbeing, and aims to preserve those values of the trees. [Ref. 1]
Mental health and well-being activities
Particularly valuable trees, such as large old ones, that people may have a relationship to are prioritised to preserve. [Ref. 1]
Implementation activities and NBS focus
Implementation activities
1. The municipal park and nature department was tasked by the political park and nature board to update the existing tree policy.
2. The policy was drafted by a working group consisting of municipal employees and experts within biology, architecture and landscape architecture.
3. The policy was approved in 2016 by three different political boards: park and nature, traffic, and construction.
4. Based on the policy, the municipality will develop a system for maintaining the city's trees in a sustainable, long term manner.

Specify primary beneficiaries
1. Local government/Municipality: Some of the ecosystem services benefit the municipality, who would have to deal with the effects of losing ESS, such as increased flood risk.
2. Citizens or community groups: Trees have social values such as increasing wellbeing and creating a more pleasant climate.
3. Young people and chilren: The policy highlights that for children, access to green spaces are particularly important and areas with trees are inviting for play.
[Ref. 1]
Measures for inclusion of marginalised groups
In choosing tree species and locations, the creation of hospitable environments that are inviting to children should be considered [Ref. 1]
Governance

NBS intervention implemented in response to a national regulations/strategy/plan
Yes
Please specify the national regulations/strategy/plan
Three of the Swedish national environmental goals, established by the Riksdag (parliament), influenced the creation of the policy: 1. Clean air, 2. A good built environment and 3. A rich plant and animal life. The policy also refers to a national guidance document for considerations when dealing with trees in public environments, published by the Swedish National Heritage Board (government agency) [Ref. 1-2].
If there is a relevant strategy or plan, please specify the theme/type of the plan
NBS intervention implemented in response to a local regulation/strategy/plan

Impacts, benefits
Please specify other environmental impact
Achieved increased consideration of ecologival values of trees in governance
Please specify other economic impact
Expected reduced medical costs due to health benefits from trees
Description of environmental benefits
1. Expected increased conservation or restoration of ecosystems; Expected reduced biodiversity loss: The implementation of the policy means that the preservation of trees will be considered in exploitation or and construction projects by the City of Gothenburg, promoting conservation of ecosystems [Ref. 1, 2]
2. Achieved increased consideration of ecological values of trees in governance: The policy means that the ecosystem services provided by trees will be considered in planning and governance by the City. This could have further indirect benefits, such as mitigation of floods and heatwaves, and improved air quality [Ref. 1].
Description of economic benefits
Expected reduce financial cost for urban management: The tree policy states that the long term sustainability and management should be considered, giving trees the right conditions to grow healthily. An expected effect from this is a reduced cost for tree management. Additionally, the ecosystem services promoted by the policy may indirectly yield economic benefits such as positive health effects leading to reduced medidal costs, or increased water retention capacity leading to reduced stormwater management costs [Ref. 1].
Description of social and cultural benefits
1. Expected protection of historic and cultural landscape / infrastructure: The policy states that old trees are an important part of the city landscape's history, and should be protected.
2. Achieved increased awareness of NBS and their benefits: The policy informs the municipal organisations as well as other actors in the city who read the policy about the benefits of trees [Ref. 1].

Additionally, the policy may have indirect effects when implemented in other projects which lead to an increase in the number or ecosystem service provision of trees, such as improved recreational opportunities, improved mental health or physical health [Ref. 1].

Description of locals satisfaction with the project
There has been some criticism from citizens not regarding the policy itself, but the way the city is implementing, or not implementing it. A few news and debate articles show negative sentiments regarding the city's choice to take down trees in different locations. They refer to the tree policy, claiming that it is not being followed. This can be seen as an indirect criticism of the policy, as it is not percieved as doing what it should [Ref. 3-5]
