From our working holiday volunteering with leopards, caracals and Cape biodiversity in South Africa

The collective efforts of the team are beginning to bear fruit.

Bat surveys have been going both using ‘static’ detectors – stationed in set locations – and using detectors connected mobile phones for night time transect surveys. This will allow us to compare and contrast species richness between different habitats and ultimately build a bat map for Blue Hill.

This has also meant many hours of data processing and sonogram analysis. Judy and John and have been leading the charge in labelling bat calls, and identifying the differences between a Cape horsehoe and a Cape serotine bat.

The second array of small mammal trapping has also been completed and the results are intriguing. The recent fires do not seem to have negatively impacted the small mammals. And we appear to have trapped two species not previously recorded at Blue Hill – which of course needs expert verification. But could indicate a potential response to fire.

Understanding how fire drives this ecosystem and species respond to it is important. And current literature seems scarce on small mammals (based on the searches of our resident professor – thank you Peter). Typically, our field research is generating more questions than answers.

We have also made progress with one of our main target species – the Cape leopard. On one of the bat transect surveys, a set of large eyes were spotted in the rocks on the south road. This was followed, by hearing a low growling noise, whilst visiting some rock art locations on Sunday afternoon, during our day off. This might sound more speculative than scientific, however, on Monday morning leopard tracks were located only metres along the same track, and less than 1 km from the base – so they are in the area!

We’ve somehow also managed to complete yet more surveys at Blue Hill and across the wider Karoo, set out yet more vegetation monitoring plots, and find time for a geology talk (from Chris Lee).

A great job by all so far.
