Finding answers... For what we should, but don’t know!
Scientific enquiry has produced amazing quantities of knowledge
We know more about the fascinating workings and the fragility of the natural world than ever before. And we use that information as best we can to conserve the world for all its living constituents and their offspring.
Yet there are many gaps to fill!
Great numbers of organisms have never been described, countless mysteries of life elude us, and we comprehend little or nothing of many fundamental environmental processes.
The more gaps are filled, the better we understand natural processes
With a good understanding of natural processes, measures to care for that which must be preserved will improve. And we will be more equipped to restore that which has been broken.
Everything is possible, but only if we look
Counting giraffes: A comparison of abundance estimators on the Ongava Game Reserve, Namibia
Camera traps are a versatile and widely adopted tool for collecting biological data for wildlife conservation and management. While estimating population abundance from camera-trap data is the primary goal of many projects, the question of which population estimator is suitable for analysing these data needs to be investigated. We used data from a 21-day camera-trap monitoring period of giraffes on the Ongava Game Reserve to compare different methods of estimation. We estimated the population size to be 104 giraffes and found that the most robust estimator was the Capture-Recapture method relying on individual identification.
