Tree maintenance can be challenging when your property sits on uneven, hilly, or sloping ground. In Perth, these landscapes are common and require extra care to manage tree health, stability, and soil safety. Proper maintenance supports healthy growth and protects nearby buildings, fences, and people from potential hazards.

At Lumberjacks, our experienced arborists specialise in managing tree pruning, tree removal, and stump grinding on complex sites where safety and precision are essential.

Why Sloping Terrain Needs Special Tree Care

Steep or unstable ground affects how a tree’s root system anchors into the soil. Without proper support, heavy rain, erosion, or strong winds can cause trees to lean, uproot, or fall. This risk is especially concerning for Perth commercial or residential properties located near retaining walls, driveways, or power lines.

Regular inspections and tree risk assessments help detect early signs of instability, such as exposed roots or tilting trunks. Addressing these risks promptly prevents costly damage and ensures long-term safety.

Key Techniques for Tree Maintenance on Difficult Terrain

Maintaining trees on steep or uneven land requires careful planning and professional expertise. Below is a quick reference comparing common challenges and recommended arborist solutions.

Challenge Recommended Solution
Soil erosion on slopes Apply tree mulching and establish ground cover vegetation.
Unstable or leaning trees Conduct tree risk assessments and perform selective pruning to balance weight.
Difficult access or steep terrain Use specialised rigging, climbing systems, or crane-assisted tree removal.
Damaged or decayed roots Schedule stump grinding and soil aeration to restore stability.


1. Strategic Tree Pruning

Proper tree pruning reduces wind resistance and helps balance weight on slopes. Arborists selectively remove branches to maintain a stable structure and prevent trees from becoming top-heavy, which can lead to uprooting in poor soil conditions.

2. Safe Tree Removal on Uneven Ground

In some cases, unstable trees on slopes must be removed. Tree removal on steep terrain requires advanced rigging systems, cranes, or elevated platforms to safely lower sections without damaging surrounding property. Hiring professionals ensures safe removal and compliance with Perth council regulations.

3. Root and Soil Management

Healthy roots are essential for stability. Mulching and soil aeration encourage root growth and moisture retention. Applying tree mulching helps control erosion by protecting the soil from runoff and compaction.

In areas prone to washouts, installing retaining barriers or planting ground cover vegetation can further strengthen the slope and prevent erosion.

4. Stump Grinding and Site Levelling

Once a tree is removed, the remaining stump can weaken the slope or attract pests. Stump grinding removes the leftover stump safely and allows soil to stabilise. This creates a safer, even surface for replanting or landscaping.

5. Ongoing Tree Maintenance and Inspections

Regular tree maintenance is vital on sloping terrain. Annual checks ensure your trees adapt well to changing soil and weather conditions. Arborists assess growth patterns and may recommend tree lopping, palm tree removal, or tree risk assessments to maintain balance and safety.

Safety and Compliance Considerations

Perth councils require property owners to ensure trees on sloping land do not pose risks to neighbouring properties or public areas. Working with qualified arborists ensures all maintenance is compliant, professional, and environmentally responsible.

At Lumberjacks, safety is always the top priority. We use specialised climbing, rigging, and lifting equipment to manage trees on steep and challenging terrain while following Australian Work Health and Safety (WHS) standards.

Trees on Sloping or Difficult Terrain – FAQs

Why is it riskier to maintain trees on sloping ground?

Sloping ground can reduce footing and equipment stability, and it can also increase erosion around the root zone. This raises the risk of root instability and makes trees more vulnerable during storms or heavy rainfall.

Can trees help prevent soil erosion on hillsides?

Yes. Healthy trees help bind soil through their root systems, and mulched areas can reduce runoff and slow water flow during rainfall. Together, they support better slope stability over time.

What is the safest way to remove a tree on a slope?

The safest approach is to hire a qualified arborist with experience on steep sites. They can use controlled methods such as rigging, climbing systems, or cranes to remove sections safely and manage the drop zone.

How often should trees on difficult terrain be inspected?

At least once per year, and after storms or heavy rain. Regular inspections help identify early signs of structural weakness, soil movement, or root issues before they become hazards.

Do councils in Perth regulate tree removal on slopes?

Yes. Many Perth councils require approval before removing trees, particularly larger or native trees. Always check your local council requirements before starting any removal work.
