Supporting bat populations through artificial roost installation and welfare-positive management.
Bat house installation represents one of the highest accessibility welfare interventions available to individuals, providing direct population-level benefits to declining species at low cost. The welfare significance of declining bat populations extends to ecosystem services that support the welfare of prey species and indirectly to agricultural systems that benefit from insect control. White-nose syndrome has created welfare emergency conditions for multiple North American bat species, making habitat support through bat houses and roost protection particularly important during the recovery period. The alignment of bat welfare and human interest through ecosystem services makes bat conservation one of the easiest cases to make for wildlife welfare investment.
