Burrow use by Saharan striped polecat (Poecilictis libyca) in an agricultural area of central Tunisia

open access: yesThe Journal of Wildlife Management, EarlyView.
Saharan striped polecats in agricultural landscapes use many burrows (30–35 per season), facilitated by sandy soils. Burrow sharing is rare and mainly occurs between males and females during mating. Habitat use shifts seasonally, reflecting disturbance and soil conditions. Maintaining stable sandy habitats may be critical for persistence.
