Thermal Drone Wildlife Survey Within the Lake District National Park

Project Snapshot

The Challenge

The client required a wildlife survey to assess deer population levels, herbivore pressure, and habitat degradation across a sensitive Site of Special Scientific Interest (SSSI) within Cumbria in the Lake District National Park.

The survey aimed to support:

• Woodland regeneration planning
• Habitat restoration targets
• Understanding of browsing pressure
• Long-term ecological management decisions

Surveying within a protected landscape presented several operational considerations:

• The need to minimise disturbance within the SSSI
• Varying terrain and dense vegetation
• Reduced thermal visibility throughout the day
• The need for reliable population data across a large landscape area

Using thermal imaging drones provided the least intrusive method for wildlife population assessment while allowing efficient coverage of the survey area.

Our Approach

Boddy Environmental deployed a specialist drone survey team and drone services equipped with:

• DJI Matrice 30T
• DJI Matrice 4 backup drone
• High-resolution thermal imaging cameras
• 200x zoom RGB camera capability

Operations and drone inspections commenced at 09:00 under favourable weather conditions, with predominantly clear skies and ambient temperatures of approximately 11°C.

Flight paths were carefully planned to ensure:

• Consistent survey coverage
• Safe operations within the SSSI
• Minimal wildlife disturbance
• Accurate thermal detection across woodland and heathland habitats

Particular consideration was given to increasing solar gain throughout the day, as warming vegetation can reduce thermal detectability within woodland and hedgerow environments.

Data Capture and Mapping

The survey produced:

• Wildlife observation points
• Thermal heat maps
• Density calculation charts
• Spatial wildlife distribution data

These outputs provided the client with a clear visual understanding of deer activity and habitat pressure across the survey area.

Deer Activity and Habitat Impact

The thermal drone survey recorded:

• 130 red deer (Cervus elaphus)
• 11 roe deer (Capreolus capreolus)

Large groups of red deer were observed in both the northern and southern sections of the census area.

The southern aggregation demonstrated heightened alertness and behavioural responses consistent with disturbance, potentially reflecting:

• Existing deer management activity
• Previous exposure to drone operations
• Localised management pressure

The survey identified evidence of ongoing herbivore pressure across the site, with implications for:

• Woodland regeneration
• Vegetation recovery
• Habitat condition within the SSSI

Key Insights

The survey delivered several important ecological and operational insights:

• Thermal drone surveys provide a low-disturbance solution for wildlife monitoring within protected landscapes
• Large deer populations can create significant browsing pressure on sensitive habitats
• Wider landscape-scale surveys would improve understanding of transient deer movement patterns
• Thermal detectability within woodland habitats can reduce as solar gain increases throughout the day

The project also demonstrated the value of combining drone wildlife monitoring with habitat impact assessments to support evidence-based conservation and land management planning.

The Results

The project delivered clear and actionable wildlife survey data, including:

• Accurate deer population counts across the survey area
• Spatial mapping of wildlife activity and density
• Habitat pressure analysis to support woodland regeneration planning
• Recommendations for future deer management strategies
• A comprehensive report delivered within 7 days

The survey findings suggested that increased red deer management may help:

• Reduce browsing pressure
• Support woodland regeneration
• Minimise ecological impacts within this sensitive SSSI

It was also recommended that a broader thermal drone survey across a larger section of the National Park could provide a more representative understanding of deer density and movement across the wider landscape, due to the transient nature of the species. 

Impact

This wildlife survey using drones enabled the client to make more informed decisions around habitat management and ecological restoration within a nationally important landscape.

By combining thermal imaging, drone technology, and habitat assessment methods, the project:

• Reduced uncertainty around deer population density
• Improved understanding of herbivore pressure
• Supported evidence-based habitat restoration planning
• Delivered accurate ecological data with minimal environmental disturbance

The thermal drone survey also highlighted the growing role of advanced drone wildlife monitoring in supporting sustainable land management across protected UK landscapes.
