If you are wondering about having a real, impactful, meaningful way to spend your vacation helping with conservation - this is a (if not the) great opportunity.
The teams are small, you get to interact a lot with your monitor and colleagues on the back of the car, you get to know how the conservation work with ecologists, rangers, reserve managers is run and monitoring animals and animal populations is just ... great and worth every minute spent outside, in the back of the car. The monitors are really skilled, both academically and in practice. there are lots of good stories, hands-on work collecting data about the animals in the reserves and great visuals - sunrise, sunset, etc.
It is well invested money, it is worth spent the time. I came back with a completely different picture of conservation work, and why I would go back to Africa or other continent to watch nature. Every hand was helpful there, and I came back thinking about my return.
