Conservation and Management

Mrs. Moreau's Warbler is endemic to the montane forests of Tanzania, where it is known only from the Uluguru Mountains, Ukaguru Mountains and Rubeho Mountains. It is expected to have a small global population (500–1,500 individuals) that is likely in decline owing to habitat loss and degradation. It has therefore been listed as Near Threatened by BirdLife International (34).

Effects of Human Activity

Within the Uluguru Nature Forest Reserve, the forested lower slopes have been subject to clearing for farming, while extremely steep and inaccessible terrain have protected the main montane forest block (J. Fjeldså, in litt. 2007 and N. Burgess, in litt. 2012 in 34).

In the Ukaguru Mountains, the main disturbances in Mamiwa-Kisara North Forest Reserve are agricultural encroachment in some areas where boundary marking is lacking, pit sawing, and pole cutting which has resulted in fewer plant and bird species (35). It should be noted though, that while Mrs. Moreau's Warbler depends on forest for its survival, it may tolerate considerable human disturbance in the forest if dense herbaceous vegetation is allowed to regenerate (J. Fjeldså, in litt. 2007 in 34),

Fieldwork in Ukwiva Forest in 1993 found the human impact on the forest negligible (28) most likely due to its remote location. The present status of the forest is unknown.


The Uluguru Nature Forest Reserve comprises the former Uluguru North, Uluguru South, Bunduki I, and Bunduki II forest reserves, and the Bunduki ‘gap’ corridor, where forest is being restored on former farmland to provide for biological connectivity between northern and southern parts of the nature reserve (36). This is likely to benefit Mrs. Moreau's Warbler and other forest bird species.
