Conclusions
Thermal imaging technology provides an efficient method for detecting rabbit warrens and entrances in all vegetation types (open, vegetated and mixed), surpassing the use of visual inspection alone. Improved detection of warrens and their entrances can lead to more effective control programs, ensuring all warrens and entrances within an area are identified. This should lead to reduced control costs over time due to decreased rates of reopening. Both consumer and professional thermal imagers can be used, however, consumer imagers should be supplemented with additional technology due to their poor exportable Frame rate. Low exportable Frame rates produce noisy and blurred imagery. This causes hot spots to look like indistinguishable white blobs which ultimately results in a high number of false-positive detections.
