Tree Health, Disease & Pest Management
Proportionate, risk-based support for trees and woodland
Countryside Science provides professional support for tree health, disease, and pest management across a wide range of land-use contexts, from individual trees to woodland and forestry settings.
Tree health issues are often identified at points of uncertainty — following storm damage, during management planning, in response to visible decline, or when public safety, liability, or funding considerations come into play. Decisions are frequently made by non-specialists who need clear, defensible advice rather than blanket prescriptions.
Our role is to help clients understand what they are seeing, what the risks are, and what action — if any — is appropriate, based on site context, objectives, and current best practice.
Understanding the issue before acting
Countryside Science offers identification and initial assessment as a standalone professional service, providing clarity at an early stage and helping clients avoid unnecessary intervention or inappropriate responses.
This service may involve a site visit or walkover to identify signs of disease, pest activity, or decline, and to explain their significance in context.
Initial assessment typically includes:
Identification of tree species and observed symptoms
Recognition of disease or pest indicators
Differentiation between serious issues and normal variation or stress
Quantifying risk to tree stands in commercial forestry
This service can stand alone or act as a gateway to more detailed assessment or planning.
Risk and prioritisation
Understanding actual risk versus perceived risk
Distinguishing individual tree issues from wider stand-level concerns
Prioritising action where resources are limited
Disease and pest interpretation
Avoiding misdiagnosis or overreaction
Understanding progression, tolerance, and variability
Recognising when intervention is necessary — and when it isn’t
Balancing objectives
