Julio Cesar Voltolini, As Meghan Bohn stated, it depends on the country. I spent time in Namibia as well, and many hunting operations worked with private companies who owned private land or cooperated with other private land owners to create conservancies. With these private hunting companies, many (not all) did game counts regularly and knew their land and their animals well. Game counts by private land owners usually consist of driving transects or waterhole counts from a hide. Private land owners would do counts with helicopters (though this is expensive) usually during the process of transporting wildlife. Wildlife are often moved between farms through game capture, as laws have encouraged fencing. If an animal is on your property in Namibia, its yours (unless it is a black rhinoceros or something). So fencing has been encouraged in this way. As you can imagine, hunters want to take large bulls, so males are sought after and often requested during wildlife movement between farms (private land). But this all has to do with game such as antelope, zebra, wildebeest, and giraffe. Tags for lions, elephants, and rhinoceros is another story altogether.
I'd recommend contacting some hunting companies abroad in Africa (in your focus countries). Perhaps you could provide incentive for information, by offering them some calculations? Another approach could be looking at National Park wildlife counts that are bordered by private land owners that have trophy hunting operations. There may be a surplus of data collected by National Parks or scientists working withing the parks. I hope this is helpful Good luck on your endeavors, Matthew Solberg On Tue, Jun 26, 2018 at 8:32 AM, Júlio Cesar Voltolini <jcvol...@uol.com.br> wrote: > Dear friends, > > We read so much discussion about hunting in the last years.
