Estate Tree Management
A large estate can have hundreds of trees spread across parkland, woodland, boundaries, and around buildings. Each one ages, grows, and changes over time - and the legal and safety obligations that come with them don't stand still either. A veteran oak with a failed limb can close a footpath. An unrecorded TPO can stop a barn conversion in its tracks. A storm can bring down a whole avenue overnight.

Frequently Asked Questions
Do we need a tree management plan?
There's no legal obligation, but it's the most cost-effective way to manage trees across a large site. A plan means safety inspections happen on schedule, work is budgeted in advance rather than triggered by emergencies, and you have documented evidence of responsible management if anything goes wrong. It also strengthens applications for Countryside Stewardship and other grant funding.
How often should our trees be inspected?
It depends on the level of risk. Trees near buildings, roads, footpaths, and car parks typically need annual checks. Trees in less-trafficked areas might only need assessing every three to five years. Thor's Trees sets up an inspection programme based on the specific layout and use of the estate.
What if there are bats roosting in a tree that needs pruning?
Bat roosts are protected year-round, and disturbing one is a criminal offence regardless of the time of year. Thor's Trees carries out preliminary habitat checks before starting work and advises on timing and approach where bats are likely to be present. In most situations, the work can still go ahead with appropriate licensing and precautions in place.
Our parkland trees are getting old and sparse - do they need replacing?
Not necessarily. Veteran trees naturally thin out, hollow, and shed limbs as they age - that's normal behaviour, not decline. These features are also what make old trees ecologically valuable. Thor's Trees assesses each tree individually and recommends the minimum intervention needed to manage any genuine safety concerns. Succession planting alongside aging trees - rather than replacing them - is usually the better approach.
Can you help with grant applications for tree and woodland work?
Thor's Trees can provide the surveys, management plans, and supporting documentation needed for Countryside Stewardship Higher Tier applications and Woodland Management Plan grants. Having professional arboricultural evidence behind the application significantly improves the chances of approval.
Do we need a felling licence to remove trees on estate land?
If more than five cubic metres of timber is being felled in a calendar quarter, a licence from the Forestry Commission is required. There are some exemptions, but on estate land with mature trees the threshold is reached quickly. Thor's Trees advises on when a licence is needed and submits the application.
