A global meta-analysis of 59 studies encompassing 631 cases of animal abundance changes in areas of tree mortality over the past 7-59 years, primarly in North America and Australia, with a few sites in other regions . Overall, in areas with documented high tree mortality, bird abundances increased , there was no significant trend for mammals , a slight trend towards declines in invertebrates , and insufficient information to categorize the responses of reptiles . However, within groups, significant differences appeared. Mammals that use trees as refugia showed declines with tree mortality , but flying mammals  increased . Ground-nesting, ground-foraging, tree-hole nesting and bark-foraging birds increased most, but nectar-feeding and foliage-gleaning birds declined . Within invertebrates, declines were strongest in ground-foraging predators and detritivores  .
