The area outlined in red represents the study area, covering the Masai Mara National Reserve and the northernmost section of the Serengeti National Park.The area outlined in white indicates the corresponding area presented in Fig. 8. The histogram shows the calculated wildebeest frequency distribution for each scene. a Spatial distribution hotspot map of wildebeest detected in July 2015. The image is located in the northernmost section of Serengeti National Park with the Mara River flowing through. The maximum wildebeest density is about 1500 per km2. b Spatial distribution hotspot map of wildebeest detected in August 2018. The image is located in the Mara Triangle inside the Masai Mara National Reserve, covering the border of Kenya and Tanzania. The wildebeest are near the border and the density peak is more than 4000 individuals per km2. c Spatial distribution hotspot map of wildebeest detected in August 2013. The image covers the Mara Triangle in the Masai Mara National Reserve and the northern section of the Serengeti National Park. The wildebeest are mostly distributed in the Serengeti National Park near the border and the density peak is about 4000 individuals per km2. d Spatial distribution hotspot map of wildebeest detected in August 2009. The image is located in the northwest corner of the Masai Mara National Reserve. The wildebeest density peak is about 6000 individuals per km2. e Spatial distribution hotspot map of wildebeest detected in September 2010. The image is located in the north Serengeti National Park with the Mara River flowing through. The wildebeest are mostly on the north side of the Mara River and the density peak is about 3000 per km2. f Spatial distribution hotspot map of wildebeest detected in October 2020. The images cover the east side of the Mara National Reserve and northeast Serengeti National Park. The wildebeest span sparsely across the Mara National Reserve and Serengeti National Park and the density peak is about 2000 per km2. The maximum wildebeest density displays a large difference in terms of months in the dry season. Satellite image © 2009–2020 Maxar Technologies.
