Bd is a very important chytrid fungus because it appears to be capable of infecting most of the worldâs approximately 6,000 amphibian species and many of those species develop the disease chytridiomycosis which is linked to devastating population declines and species extinctions (Berger et al., 1998; Skerratt et al., 2007; Fisher et al., 2009).
The blight fungus is carried from tree to tree by small animals and insects, who pick up and thansport the infected spores from tree cankers on their feet, fur, and feathers. The disease is also spread from tree to tree by weather elements such as wind and rain.
