Arvicanthis niloticus
Drawn from open occurrence records in and around Ruaha National Park, aggregated onto a 25 km grid. A cell is matched by its centre, which can sit up to 16 km outside the boundary, so this covers the surrounding country too.
Occurrence records measure where people looked and found something, which is not the same as where the animal is. This is a relative likelihood, not a probability.
Records exist for July, with the widest coverage in July. A quiet month can mean the animal was absent, or that nobody was looking.
A grid cell is a square of the map, not a sighting: 4 squares of 25 km carry records for African Arvicanthis in and around Ruaha National Park, and the 43 records behind them were collected by other people and published openly. Nothing here counts animals, and a place with more records is not always a place with more animals.
Ngorongoro Conservation Area, Serengeti National Park and Ruaha National Park are among the eight atlas places where the African Arvicanthis is recorded. Records of this mammal concentrate in Benin, Tanzania, Rwanda, Mali and Senegal. The atlas holds 956 records of the species across 11 countries.
Of the 14 species with an atlas page recorded in and around Ruaha National Park, the African Arvicanthis is the 7th most recorded.
