Population justification: The total population is estimated at 1,000-1,500 individuals (R.E. Simmons in litt. 2007); however, it is thought that the number of mature individuals does not exceed 1,000, thus the range 250-999 mature individuals is retained for the population estimate. |
|
Trend justification: Recently, the population is thought to have experienced a slight decline owing to the loss of some patches of renosterveld vegetation in Overberg (R.E. Simmons in litt. 2007). Future declines may occur because of a predicted decrease in rainfall in the western parts of its range, which could lead to a reduction in mouse populations (R.E. Simmons in litt. 2007). However, the trend is maintained as stable until further data are obtained. |
