The distribution of R. evertsi is given in terms of political Divisions, as well as in terms of Vegetational coverage. 2. R. evertsi is seen to be present in all forest, parkland and grass land areas with a rainfall above 10 inches. It is absent from all Karroo areas below 10 inches; it appears to maintain a precarious footing in mixed Karroo scrub and grass areas with a rainfall between 10-15 inches. 3. It shows no essential periodicity in its activities. 4. It is not controlled by dipping alone; handdressing with dipping is essential for its suppression.en© 1950 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2017 University of Pretoria.
