Urban bats face specific threats from lighting, building development and pesticide use that cause individual suffering and population-level declines requiring targeted management.
Urban bats face a persistent accumulation of stressors that reduce their ability to meet basic needs of food, shelter and reproduction. Disrupted foraging from light pollution means bats expend more energy for less reward, leaving less for reproduction and winter fat storage. Roost destruction removes not just habitat but removes the learned knowledge of roost sites passed between generations. Individual bats that lose roost sites face exposure, temperature extremes and vulnerability to predation. The cumulative welfare burden of urban living for bats is substantial even when individual animals survive.
