5 Things You Might Not Know About Arborists

Fun Facts

When most people think of arborists, they picture someone in a harness cutting back tree branches. But the truth is, the profession is much broader, more technical and more critical than many realise. In this article, we’ll explore 5 things you might not know about arborists, shedding light on the expertise behind every cut, climb and consultation.

1. They’re Highly Trained and Certified

Arborists are not simply outdoor workers with saws. They undergo formal training and must gain qualifications such as NPTC units, Lantra certifications or Level 3 Diplomas in Arboriculture. Their knowledge includes tree biology, soil science, pest identification and structural assessment. This technical grounding allows them to make informed decisions that protect public safety, preserve trees and support biodiversity.

2. They Assess Tree Health, Not Just Structure

Arborists are often the first to spot signs of disease, decay or environmental stress. Using visual inspections, decay detection tools and soil analysis, they can diagnose issues before they become hazardous. While many people associate arborists with felling trees, their main role is actually to retain and care for them through pruning, soil improvement, bracing and long-term monitoring.

3. They Play a Key Role in Planning and Development

Whether it’s a housing estate, a school extension or a commercial development, arborists help shape how trees fit into the design. By producing BS5837 tree surveys and Arboricultural Method Statements, they advise developers on how to minimise impact, preserve root systems and maintain healthy trees during and after construction. Their input can be vital for gaining planning permission or meeting biodiversity requirements.

4. They Work in Challenging and Dangerous Conditions

Tree work is one of the most hazardous professions in the UK. Arborists frequently operate at height, use chainsaws in awkward positions, and work in proximity to roads, power lines or railway tracks. To do so safely, they rely on strict procedures, PPE, rescue plans and ongoing safety training. Specialist roles like utility arboriculture require advanced qualifications and detailed knowledge of infrastructure safety protocols.

5. They Support Environmental Goals Beyond Tree Work

Arborists often contribute to wider environmental objectives, such as climate resilience and habitat protection. They may recommend native species for replanting, advise on creating wildlife corridors, or help manage invasive species. Their work supports tree retention, urban greening and the delivery of biodiversity net gain strategies on development sites.

Did You Learn Something New?

Those are 5 things you might not know about arborists, but there are many more. Behind every tree survey, pruning job or emergency callout is a trained expert making informed, responsible decisions. Whether they are safeguarding public spaces, guiding planning decisions or caring for our green infrastructure, arborists are key players in the balance between people, trees and the built environment.
