René Nauta
Track and sign Evaluator
René Nauta has been a passionate tracker for many decades. Together with his partner Beke Olbers they run their company ‘EXTRA Bushcraft’ founded in March 1997. Since that time, wildlife tracking has been a primary component of its course contents.
Besides courses in Holland they also offer expeditions to wilderness areas like the Carpathians, Rocky Mountains, Belarus and the Kalahari (in coorporation with the Bushmen), etc
Beke and René have published 2 elaborate books about bushcraft: het ‘Bushcraft handboek’ (2015) en ‘Buitenleven’ (2023)
In 2012 he was invited to join the first CyberTracker Evaluation in the Lake District, England, and was hooked from then on even more. He was awarded his specialist certification in 2014 and began his journey to become T&S Evaluator, alongside John Rhyder and Joscha Grolms.
In March 2018 he received Evaluatorship and now conducts evaluations in Holland, Belgium and France. More trainings across Europe are on the horizon.
In May 2019 he published an elaborate fieldguide (‘Het Prentenboek’) with his co-author Aaldrik Pot. The book is a unique and comprehensive presentation of the morphology and tracks of mammals, birds, amphibians, reptiles and invertebrates across northwestern Europe. Plus a chapter about animal gaits, how to collect and store tracks. Plus the uses for monitoring or guiding. A set of (life size) fieldcards with tracks of mammals and birds was also published at the same time.
