Nectophrynoides wendyae is confined to a single location above Chita in the Udzungwa Scarp Forest Reserve in the Udzungwa Mountains, Tanzania, 1500 to 1650m above sea level. Site specific and forest dependent.
Undisturbed forest, forest floor leaf litter.
Data not available but probably feeds on small insects and other terrestrial invertebrates of the leaf litter.
Said to be quite common but population also described as decreasing, although the basis for this is unknown.
Despite being rated as Critically Endangered the population presently seems to be healthy ('relatively common'; Stuart et al., 2008, Menegon, pers. comm.).
