Tree Pruning vs Tree Felling: How to Decide for Your Trees in Brussels

As a certified arborist and arboriculture coordinator at Plumridge, I am often approached by homeowners in central Brussels and Walloon Brabant who are unsure whether they need tree pruning or tree felling. The decision is never trivial: it depends on the tree’s health, the safety of the neighbourhood and local regulations. In this article, I break down the key points to help you decide between tree pruning vs tree felling.

1. What is the goal of the intervention?

First, you need to identify why you are intervening on the tree:

• Safety: branches threatening power lines, road signs or pedestrian walkways.
• Aesthetics: irregular shape, dense foliage blocking the view.
• Tree health: disease, pests or physical damage.
• Legal compliance: meeting the requirements of the Brussels-Capital Region’s Green Space Management Plan (PGEV).

If the goal is to correct a defect or stimulate growth, tree pruning is usually the right answer. However, if the tree has serious trunk or root system damage, tree removal may be the safest solution.

2. Assessing the tree species and health

Brussels and Walloon Brabant are home to many local species: pedunculate oak, Norway maple, lime, birch, and even some ornamental trees in the Etterbeek neighbourhood. Each species has its own requirements:

• Oak: very resilient, but susceptible to trunk cracks. A major wound in the trunk may justify tree felling.
• Maple: low branches often cause problems on the streets of Schaerbeek. Selective pruning is usually sufficient.
• Lime: soft wood that can break under the weight of its fruit. A major structural imbalance may require tree removal.
• Birch: naturally produces many dead branches. Maintenance pruning is recommended every 5‑10 years.

An arborist will carry out a visual assessment and, if necessary, a trunk examination (probe) to determine the degree of decay or infestation. This technical evaluation directly answers the question of tree pruning vs tree felling.

3. Planning permission and regulations in Brussels and Walloon Brabant

Brussels communes (Uccle, Woluwe‑Saint‑Pierre, Molenbeek) and towns in Walloon Brabant (Wavre, Waterloo) apply strict rules:

• All tree felling requires a planning permission (permis d’urbanisme), even for private trees, when they exceed 12 m in height.
• Tree pruning that removes more than 30% of the canopy must be declared and sometimes authorised by the landscape planning department.
• In protected areas (Bois de la Cambre, Forêt de Soignes), only emergency interventions are accepted without prior approval.

Ignoring these requirements can result in fines or an obligation to replant an equivalent tree. Before making any decision, you must check the legal framework in your commune.

4. Cost and environmental impact

Costs vary widely:

• Light pruning (removing small branches): €70‑120/h depending on height.
• Heavy pruning (cutting a trunk section over 30 cm): €250‑500.
• Tree felling with controlled dismantling and wood removal: €500‑1,200 depending on size and location.

From an environmental perspective, pruning preserves biomass and supports the tree’s health, whereas felling results in habitat loss and requires replanting. Under the Brussels Green City strategy, the municipality encourages controlled pruning.

5. When tree felling becomes unavoidable

Here are the scenarios where tree removal is the only option:

• A trunk cracked to the point of threatening stability.
• Irreversible dead wood infection spreading through the tree (white rot).
• A tree located on a busy site where any fall could cause serious injuries.
• A legal obligation following a decision by the Public Landscape Planning Service (SPAP).

In these cases, you need to plan the operation with a qualified professional, using appropriate equipment (cranes, safety ropes) and obtaining the necessary permits.

6. Quick checklist to help you decide

Use this list before contacting an arborist:

1. Identify the species and measure the trunk height.
2. Look for visual signs: cracks, fungi, dead branches.
3. Assess the risks to passers-by and neighbours.
4. Check your commune’s regulations (permits, thresholds).
5. Determine your budget and objectives (safety, aesthetics).

If you have any doubt at all, the best course of action is to call a certified arborist. A free assessment will help you confidently answer the question of tree pruning vs tree felling.
