Wendy’s toad is particularly vulnerable to extinction due to chytridiomycosis through the introduction of chytrid fungus. This fungal disease was the final factor responsible for the extinction of the related Kihansi Spray toad, N. asperginis, announced recently. The Kihansi Spray toad was known from several populations in the Kihansi Gorge also in the Udzungwa Mountains, Tanzania.
The single population of Wendy’s toad would mean that it would likely be wiped out by a single outbreak of chytrid infection which is caused by the zoospores of Batrachochytrium dendrobatidis. All possible safeguards and measures should be taken to prevent the introduction of this disease.
