Let’s be honest—construction sites aren’t exactly tree-friendly. Diggers, heavy machinery, and piles of building materials can wreak havoc on roots faster than you can say “Tree Preservation Order.” But protecting trees during development isn’t just about ticking a box for planning approval; it’s about safeguarding a vital part of the ecosystem—and avoiding some pretty hefty fines while you’re at it.
Why Tree Protection Should Be Top of Your Checklist
Trees aren’t just a “nice-to-have” on your site plan. They improve air quality, increase property value, and keep local councils happy. Oh, and did we mention they’re legally protected? Under the Town and Country Planning Act, damage to protected trees can cost you up to £20,000 per tree. Ouch.
What Happens When Trees Aren’t Protected?
Tree damage doesn’t just happen above ground. Most trees have roots spreading two to three times wider than their canopy, which means they’re prime targets for accidental damage. Here’s what can go wrong:
- Soil Compaction: Heavy machinery parked near trees can squash the life out of roots (literally).
- Root Severance: Trenching too close to trees cuts off their lifeline, leaving them to wither.
- Toxic Runoff: Chemicals like cement or oil spill into the soil, poisoning roots.
What is a Tree Protection Zone, and Why Should You Care?
Think of a Tree Protection Zone (TPZ) as the VIP section for your trees—no unauthorised access, no exceptions. It’s a fenced-off area covering the tree’s root system and canopy, protecting it from damage during construction. These zones are sacrosanct (yes, we’re fancy like that), so no materials, machines, or misguided lunch breaks are allowed inside.
How to Protect Your Trees Like a Pro
- Get a Tree Survey
Before a single shovel hits the ground, bring in an expert (like us). We’ll map out the trees, assess their health, and mark their TPZs. - Erect Protective Fencing
Install sturdy fencing that meets British Standard BS5837. This isn’t the time for makeshift barriers—flimsy tape won’t stop a JCB. - Keep an Eye on Things
Even the best-laid plans can go sideways. Regular monitoring ensures your TPZ stays intact, and your trees stay safe.
