Most migratory routes have been blocked due to agricultural expansion; bushmeat hunting and resident hunting have reduced wildebeest, hartebeest and oryx populations by 88%, 90% and 95%, respectively.
As of the early 1990s approximately 10.5% of lands in the Tarangire ecosystem were under agricultural cultivation much of it abutting the Park, and this has accelerated dramatically in the last 15 years. Sport and illegal hunting is common in the area.
Considerable controversy has arisen between some stakeholders over the corridor between Tarangire NP and villages to the east, and politically this is a very sensitive area. Increasingly the villages adjoining the National Park are entering into land lease agreements with tour operators and creating concession areas which are used solely for tourism and cattle grazing.
