What is Ash Dieback?

Ash dieback (Chalara fraxinea, or Hymenoscyphus fraxineus) is a fungal disease that has spread across the UK since arriving in 2012. It affects all species of ash (Fraxinus) and ultimately kills infected trees — though the rate of decline varies significantly between individual specimens, and some show partial resistance.

Hampshire has extensive ash coverage in its hedgerows, woodlands and garden landscapes. With an estimated 80–90% of UK ash trees expected to eventually succumb, this is one of the most significant tree disease events the country has seen.

The disease kills by blocking the tree’s water and nutrient transport system. Infected trees become structurally unpredictable — they can shed large branches or fail suddenly, without the warning signs that accompany other forms of structural decline.

⚠️ Safety note: Ash trees with dieback can shed branches or fail with little warning, even where they look structurally sound. If you have an ash tree showing signs of dieback near a path, building or road, have it assessed promptly.

Signs of Ash Dieback

  • Crown dieback — dead branches at the top of the canopy, especially noticeable in summer
  • Wilting, discoloured or blackened leaves that fail to open in spring
  • “Epicormic” regrowth — clusters of shoots sprouting directly from the trunk or main branches
  • Diamond-shaped lesions or darkening of the bark where branches meet the stem
  • Disproportionate leaf loss compared to surrounding trees
  • Small, white-stalked fruiting bodies on dead leaf stalks in summer (early indicator)

Not all of these will be present in early-stage infection. If you’re uncertain, book a tree health survey for a formal written assessment.

What We Can Do

We assess each ash tree on its own merits — some can be managed, others need to come down. We give you an honest, evidence-based recommendation.

🔍

Ash Dieback Assessment

We inspect the tree, assess the degree of crown dieback, check for structural integrity issues and give you a clear written recommendation. Supports insurance claims and planning decisions.

🌿

Monitoring & Management

Trees with low-level infection and good structural integrity can sometimes be monitored rather than removed immediately. We advise on realistic timescales and what to watch for.

🪓

Safe Tree Removal

Ash trees with advanced dieback become structurally unpredictable. We carry out controlled removal using sectional dismantling techniques appropriate for compromised wood.

⚙️

Stump Grinding

Following removal, we can grind the stump well below ground level so you can reclaim the space. See our stump grinding page.

TPO & Planning Advice

Many ash trees are TPO-protected. Ash dieback creates a permitted development exception for urgent safety work, but the position must be documented properly. We handle this process on your behalf.

🌱

Replacement Planting Advice

Where ash trees are removed, we can advise on suitable native replacement species — oak, field maple, hornbeam, cherry — that will provide long-term canopy cover without ash dieback risk.

Frequently Asked Questions

Not necessarily. The answer depends on the degree of crown dieback, the tree’s structural integrity, and where it stands in relation to people and property. A tree with 30% crown dieback standing in open countryside poses different risks from the same tree overhanging a footpath or building. We assess each case individually and give an honest recommendation — we won’t push for removal if monitoring is the right call.

Yes, in most cases — ash dieback creating an imminent safety risk provides grounds for removal even on TPO-protected trees, but the position needs to be properly documented and the local planning authority notified. We’re experienced with this process and will handle the paperwork on your behalf. Removing a TPO-protected tree without following the correct procedure, even for safety reasons, can result in enforcement action.

The disease spreads via airborne spores from infected leaf litter and fruits, so it will spread to nearby ash trees over time. There’s no effective chemical treatment and no way to prevent spread once the disease is in an area. The focus is on managing individual trees for safety and deciding when removal is necessary.

Highly variable. Some trees decline rapidly over 3–5 years; others show partial resistance and persist for much longer with manageable levels of infection. Younger trees typically decline faster than mature specimens. Regular assessment — ideally annually — is the only way to track progression and make timely decisions.
