Fox on the Run-Cheaper Camera Traps Fail to Detect Fast-Moving Mesopredators: Assessing the Differences in...

Area of Science:

• Wildlife ecology
• Conservation technology
• Camera trapping methodology

Background:

• Non-invasive wildlife monitoring relies heavily on camera trapping.
• Limited understanding exists on how camera trap specifications influence detection rates.
• Published studies often lack details on camera model selection and parameters, hindering replicability.

Purpose of the Study:

• To compare the detection efficacy of different camera trap makes and models.
• To assess how price range, vintage, and specifications affect predator and herbivore detection.
• To inform best practices in camera trap experimental design and data interpretation.

Main Methods:

• A passive monitoring survey was conducted at six sites in Northern Scotland.
• Three camera trap makes and models with varying specifications were tested.
• Detection rates for predators and herbivores were analyzed across different camera trap types.

Main Results:

• Significant variation in detection efficacy was observed between camera trap grades and vintages.
• Older camera trap models with lower trigger speeds and reduced night vision performed poorly.
• Detection performance was species-dependent, with notable differences for nocturnal predators.

Conclusions:

• Camera trap model choice critically impacts wildlife detection rates and study outcomes.
• Researchers and conservationists must carefully consider camera trap specifications for reliable monitoring.
• Caution is advised when comparing or applying findings from studies using different camera trap models.
