Ash Dieback on Farms and Rural Estates in Cumbria — A Practical Guide for Landowners

June 23, 2026

For most domestic homeowners, ash dieback means dealing with one, two, perhaps five trees. For farmers, estate managers and rural landowners across Cumbria and Lancashire, the scale of the challenge is often very different. Ash trees in field boundaries, farm woodlands, shelter belts, country lanes and estate parkland can number in the hundreds or even thousands on a single holding — and ash dieback is working its way through all of them.

We work with a number of farming and estate clients across South Lakeland, the Lune Valley, North Lancashire and the eastern Cumbrian fringes, and the practical questions we encounter are consistent across all of them. This guide addresses those questions directly.

How Bad is Ash Dieback in Cumbria?

The honest answer is: bad, and getting worse. Ash dieback was confirmed spreading in Cumbria several years ago and the disease is now well-established across the county. The Lake District National Park, South Lakeland and the limestone belt from Arnside through to the Lune Valley all have significant infection levels.

The pattern we see on farm visits is typically a mix of stages — some trees showing early symptoms (loss of shoot tips, some crown dieback), others in advanced decline, and a proportion already dead. In hedgerow ash, which has often been the dominant hedgerow tree across the Cumbrian lowlands, entire boundaries can be affected. In farm woodlands, the ash component — which in many South Lakeland woods is substantial — is progressively dying out.

The timescale for complete loss of infected ash trees varies from 2-3 years in severely affected trees to 10+ years in trees showing slower progression. A small percentage of trees appear to have some natural tolerance and may survive long term — these are worth identifying and retaining.

Hedgerow Ash — The Most Pressing Priority

For most farm holdings in Cumbria, hedgerow ash trees represent the most urgent risk management challenge from ash dieback. Hedgerow ash trees that die will:

Pose an increasing risk to stock, farm workers and public roads as they become structurally unstable
Potentially affect fencing lines when they fall
Block watercourses and drainage if they fall across ditches
Become increasingly expensive to remove as decay progresses

The key decision for hedgerow ash is prioritisation. Not all hedgerow ash trees need to come down immediately — the focus should be on those that are:

Adjacent to public roads, bridleways and footpaths
Leaning over farm buildings, silage clamps or other infrastructure
In an advanced state of decay where structural failure is imminent
Overhanging stock areas where a falling branch could injure or kill livestock

Trees in less critical locations — away from public access and infrastructure — can be programmed for removal over a longer period, spreading both the cost and the workload.

Farm Woodlands and Shelter Belts

For farm woodlands and shelter belts with significant ash components, the management question is more complex. A pure ash woodland that is dying out needs a plan — both for the removal of the dying ash and for what replaces it.

Key considerations for farm woodland ash dieback management include:

Timing of Felling

As we have noted elsewhere, the earlier you fell declining ash, the cheaper and safer the operation. Trees that have been dead for more than 2-3 years become progressively harder and more expensive to deal with safely. For a farm woodland with a significant ash component, getting ahead of the problem — even before all trees are obviously dead — is almost always the right approach financially.

Timber Value

Recently felled ash timber from living or recently dead trees still has commercial value. Ash timber is prized for furniture, tool handles, flooring, sports equipment and firewood — the demand for good quality ash timber has actually increased as supplies become less predictable. Trees felled while still standing and reasonably sound will command better prices than trees felled after decay has set in. If you have significant standing ash timber on your holding, it is worth discussing the timber value with a forestry contractor before deciding on timing.

We extract and process ash timber from farm woodland felling operations as part of our forestry contracting services. We can discuss timber value as part of any site assessment.

Restocking

Where ash woodland is being cleared, Countryside Stewardship woodland creation options offer grant funding for restocking with native species. This is well worth exploring — the capital costs of restocking can be significant, and grant funding can make the difference between an affordable plan and one that is not.

Choice of restocking species should take account of the site conditions. For the limestone soils of South Lakeland, suitable species include wych elm, field maple, wild cherry, hazel, hawthorn, blackthorn and guelder rose alongside oak and birch. For the heavier, more acidic soils of the Cumbrian lowlands, oak, alder (in wet areas), birch and rowan are the mainstays.

We recommend diversifying species as much as practically possible — the monoculture ash woodland that is now dying out so rapidly is itself a lesson in the risks of over-reliance on a single species.

Grant Funding Available for Ash Dieback Management

Several funding streams are potentially available to Cumbrian farmers and estate managers dealing with ash dieback:

Countryside Stewardship — Woodland Management (WT2, WT3 options) — covers management of existing woodland including phased removal of diseased ash and restocking
Countryside Stewardship — Woodland Creation (WC2 capital item) — covers restocking costs following ash removal
Tree Health Pilot — Defra has run pilot schemes specifically for ash dieback management. Check the current Forestry Commission website for the latest available schemes.
England Woodland Creation Offer (EWCO) — available for new woodland creation on land where ash has been removed

Grant scheme availability and specifications change regularly. We recommend checking directly with the Forestry Commission and Natural England for the most current information, and we are happy to advise on which options are likely to be applicable to your specific situation.

Biosecurity on Farm — Slowing the Spread

While ash dieback is now so widespread across Cumbria that biosecurity cannot prevent infection on an individual holding, good practice still matters — both to slow progression within a site and to avoid inadvertently spreading the disease further:

Clean footwear, vehicles and machinery before moving between sites — ash dieback spores can be carried on boots and tyres
Do not move ash timber, logs or arisings from infected sites to areas where ash dieback has not yet been confirmed
Report suspected cases of ash dieback to the Forestry Commission's TreeAlert system
Where possible, prioritise the removal of dead and dying ash trees before they produce further spores from infected leaf litter

How We Can Help Cumbrian Farmers and Estate Managers

We offer site assessments for farm and estate clients across South Lakeland, the Lune Valley, North Lancashire and surrounding areas. On a typical site visit we will:

Walk the holding with you and assess the ash trees present
Categorise trees by urgency and risk level
Discuss timber values and recovery options
Outline a realistic phased programme for felling, extraction and restocking
Advise on grant scheme options relevant to your situation

There is no charge for the initial assessment. We work with farming and estate clients on both one-off contracts and longer-term management programmes.
