Ground-dwelling mammal diversity is positively influenced by habitat heterogeneity and productivity in fire-prone regions. Different types of habitats and diverse fire regimes can increase species diversity. The productivity of an area has a strong impact on species diversity, with higher productivity leading to more diverse mammal populations. Prescribed fires can enhance habitat diversity, but this doesn't always result in more species. The spatial arrangement of habitat structures plays a crucial role in determining species diversity. Overall, a mix of habitats and controlled fires can help support a variety of ground-dwelling mammals in fire-prone regions.
