Colobus guereza gallarum is one of the eight subspecies of the Eastern Black-and-white Colobus (Colobus guereza). While its distribution pattern remains vague, it is known to be endemic to the tropical rainforest of Ethiopia east of the Great Rift Valley. Due to high deforestation rate during the last three decades, the C.g. gallarum population is speculated to be declined (Gippolliti and Butynski, 2008).
Following extensive habitat loss, there is increasing ad hoc report for human – guereza conflict due to crop raiding and fruits damage. This study will fill the gap of knowledge on the species threats, population size, and the extent of poaching and human—C.g. gallarum conflict.
The potential suitable habitat of C.g. gallarum, tropical rainforest, will be determined from the high-resolution satellite image and population survey will be carried out extensively and supplemented by questioner survey with the local community. In the largest populations identified during the survey, populations estimates will be carried out by using transect count. Forest cover change will be determined by comparing the forest cover of the present day to the one three decades back using satellite image. Poaching and Human—C.g. gallarum conflict mainly as a result of crop raiding will be studied from a questionnaire survey.
C.g. gallarum is currently recognized as Data Deficient (Gippolliti and Butynski, 2008). This project will provide an important baseline data to increase our knowledge of the species conservation status. The forest cover change derived from this study also can be used for assessment of conservation challenges of many other mammals of Ethiopia.
