Summary
This webinar will introduce new Otter Survey Guidelines from NatureScot. Updated based on evidence from research, it presents a new hierarchical approach to otter surveys, including identification of resting and breeding places from walkover surveys, invasive surveys or camera trapping. We’ll discuss the evidence base, methods, interpretation and logistical requirements.
Description
Otters are a European Protected Species, meaning their resting places, including those used for breeding, are strictly protected. In recent years the advent of camera trapping has provided (i) an opportunity to assess former methods of identifying holts and couches, (ii) new information on otter behaviour, activity patterns and field evidence associated with resting places, and (iii) a method for ecologists to identify or rule out sites as holts or couches.
Camera trap surveys are currently optional in otter surveys and their application has been inconsistent. Guidance is needed that enables ecologists to judge when further survey is needed over and above a walkover survey, and a method to identify or rule out resting places from walkover and invasive survey before considering camera trapping.
The new NatureScot Otter Survey Guidelines adopts an evidence-based, hierarchical field survey approach of walkover surveys and, if required, invasive surveys or camera trapping. The different approaches will be introduced, and their timing, duration, logistics and licensing requirements summarised. There will be the opportunity to ask questions to NatureScot and the authors of the guidance.
