I went to Gorongosa for a field biology course in 2016, and it was absolutely amazing. Greg Carr gave a talk to us about the park and it's mission, and it seems like they're really working hard to incorporate the park into the surrounding communities so that the locals have a sense of ownership over their park.

The megafauna are recovering at a good clip, and there's thriving bird and bug biodiversity if you're into that kind of thing (seeing Oecophylla nests was a particular highlight for me, but I'm probably in the minority there.) National Geographic did a video series about the park's recovery that I highly recommend[1], and last I heard they're working on a sequel.

Reading that made me look up "tuskless elephants", and I found this: https://www.independent.co.uk/news/elephants-africa-tusks-iv...
