‘Devastatingly cute’ bats look for bugs in forest clearings and corridors

Eastern red bats, now the most commonly detected bat in Midwestern forests, have a significant impact on tree regeneration due to their appetite for insect-damaging bugs. Forest managers can benefit from considering these bats' landscape preferences, particularly ponds and smaller forest openings.

Bats protect young trees from insect damage, with three times fewer bugs

A new study found that bats play a crucial role in protecting young tree seedlings from insect damage, with three times fewer bugs and five times more defoliation when bats are absent. The research reveals a mutually beneficial relationship between bats and oak trees, with bats serving as a key predator for insects that harm the trees.

Companies’ ‘deforestation-free’ supply chain pledges have barely impacted forest clearance in the Amazon

A recent study found that companies' zero-deforestation supply chain commitments have reduced tree clearance in the Brazilian Amazon by only 1.6% between 2006 and 2015. Despite this, over 50% of soy-suitable forests in Brazil remain unprotected. Experts call for stronger regulations to effectively combat deforestation.

Land in a cyclone’s wake becomes more vulnerable to forest fires

Researchers study links between cyclones and forest fires, finding that cyclones can create conditions ripe for fires by damaging trees and altering microclimates. As climate change increases cyclone intensity, the risk of wildfires in previously fire-resistant ecosystems like rainforests grows.
