Mastomys natalensis
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 February, July, August, November and December, with the widest coverage in July and August. 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: 11 squares of 25 km carry records for Natal Mastomys in and around Ruaha National Park, and the 162 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.
Ruaha, Mikumi and Nyerere National Parks are among 16 atlas places where the Natal Mastomys is recorded. Its records concentrate in Tanzania, Guinea, Sierra Leone, Zambia and Congo - Kinshasa. The atlas contains about 12,000 records of this mammal from 23 countries.
Of the 14 species with an atlas page recorded in and around Ruaha National Park, the Natal Mastomys is the 6th most recorded.
