A Namibia wildfire pushed savanna mammals beyond the burned boundary
WHAT THE EVIDENCE SAYS
After wildfire across a 650 km² Namibian savanna landscape, researchers used camera traps and a multi-season multi-species model for 31 mammal species, with one pre-fire and five post-fire months. Modeled community occupancy fell from 0.53 to 0.33 in burned areas, versus 0.45 to 0.43 in controls; proximal sites declined from 0.58 to 0.52. Small carnivores and burrow-associated mammals showed among the largest effects.
WHY IT MATTERS / OUR READ
Fire effects extend through animal movements and microclimate across the perimeter drawn on a burn map. Landscape-scale refuge and recovery design should track occupancy and spatial context, not assume the nearest unburned patch is unaffected.
CAVEATS / UNCERTAINTY
This single eastern Namibia fire and six-month window show early modeled occupancy, not abundance, permanent extirpation or long-run recovery. The fire was not experimentally assigned.

Camera-trap occupancy fell for 31-species community; neighboring unburned areas were not a guaranteed refuge.
