We've removed hundreds of dangerous trees over the years. Most of them had warning signs the owner didn't recognise. Here's what to look for on your own property.
What to Look for Above Ground
Start with the obvious stuff. Dead branches — they're grey, brittle, and they can drop on a dead-calm day without any warning. Check the trunk for vertical cracks, deep holes, or spots where the bark's peeling away to show soft, rotting timber underneath. See mushrooms or bracket fungi growing out of the trunk? That's decay happening on the inside.
Around Orange, species like Elm, Maple, Ash, Gum each fail in their own way. Elm trees are notorious for what we call "summer limb drop" — big, heavy branches just letting go on hot, still afternoons. No wind, no storm. They just fall. If you're noticing more twigs, bark, or leaves piling up under a tree than usual, something's going on up top.
Another tell-tale sign is a sudden lean. If a tree that's always stood straight is now visibly tilting, the root plate may be failing. Look at the canopy too — if one side has significantly less foliage than the other, the tree is likely struggling with internal decay or a compromised vascular system on that side.
What's Happening Underground
Root problems are the sneaky ones. You can't see them, but they're often worse because a root failure can bring the whole tree down — trunk, canopy, everything.
Watch for soil cracking or lifting around the base, especially on one side. Exposed roots that look damaged or are going soft and spongy aren't doing their job anymore. After heavy rain — which we get plenty of across the Central Tablelands region — saturated ground gives roots less to grip. If a tree's rocking more than usual in moderate wind, that's a red flag.
Here's one people miss all the time: construction damage. If someone's trenched, dug, paved, or built anything within a tree's root zone (which extends well past the canopy), the effects might not show for months. We see this regularly on properties in Bloomfield, Calare, Glenroi, Lucknow. The building work finishes, everything looks fine, then six months later the tree starts declining.
Seasonal Warning Signs Specific to Orange
Orange has cool winters and strong winds that can cause branch damage and tree instability. These conditions create particular stress patterns you should watch for throughout the year.
In late spring and summer, keep an eye on canopy density. Trees that fail to leaf out fully, or that drop green leaves during warm weather, are showing signs of serious internal stress. After prolonged dry spells common in the Central Tablelands region, bark can split and crack as the timber dries and contracts — those splits become entry points for fungal pathogens.
Heading into autumn and winter, check for branches that have died back since last season. Fresh deadwood in the upper canopy means something changed — root damage, disease, or water stress. After any significant storm event, walk the property and look for new cracks, fresh lean, or exposed root plates even if nothing actually came down. The damage from one storm often sets up the failure that happens in the next one.
Don't Sit on It
If any of this sounds like your tree, don't wait to see what happens. Move anything valuable out from under it — cars, outdoor furniture, the kids' trampoline — and give us a call. We can usually get out for an inspection within a couple of days. Same day if it's urgent.
Honestly, the best thing you can do is get your trees checked every two to three years by someone who knows what they're looking at. Catching a small defect early is a lot cheaper than dealing with a tree through someone's roof. Especially around Cook Park and Mount Canobolas where the mature tree canopy is part of what makes the area special.
A professional arborist assessment typically covers visual inspection from ground level, trunk sounding to detect internal cavities, root zone evaluation, and a written report with clear recommendations. It's a small investment that can prevent thousands of dollars in property damage — or worse, a serious injury.
