of monitored Archey's frogs has decreased by 88% between 1996 and 2001 and this is believed to be resultant of a primitive fungus Batrachochytrium dendrobatidis which is implicated in the declines and extinction of nearly one third of the earth's frogs and toads. More

In September 2001 the Archey's frog population was found infected with the chytrid fungus, believed to be responsible for a rapid decline in a number of species. More
