Amietia wittei is a locally common species inhabiting montane grasslands at elevations of above sea level. It is associated with streams and can be found in areas of low-intensity agriculture. It is suffering from some habitat loss and deterioration caused by expanding human settlements, wood collection, and logging. It occurs in several national parks: Aberdare and Mount Kenya National Parks in Kenya, Mount Elgon National Park in Kenya/Uganda, and Kilimanjaro National Park in Tanzania.
