Giraffe populations in Africa have increased by 20 percent since 2015 thanks to greater conservation efforts as well as more accurate surveying techniques and data.
After the government in Niger put forth the first national conservation strategy in Africa to protect the giraffes from extinction due to poaching, the population of the endangered animals rose back up by more than 11% each year.
