This study deals with the current distribution, abundance and impacts of mole rats inrnagricultural fields in Angacha. It was carried out from August 2005 to April 2006rncovering the wet and dry seasons. The mole rat is the main rodent pest on Enset andrnpotatoes in Angacha though its effect is minor in other crops. Direct total count wasrncarried out from fresh surface signs (mounds) to estimate abundance and distribution ofrnmole rats. Vector gopher traps and conical “Yeshibowotimed” were set to serve as snaprnand live traps. Stomach content analysis was carried out to determine food content ofrnmole rat. These were applied in randomly selected four sites representing the “Dega” andrn“Woina-dega” climatic zones. Total counts using traps by digging and “Yeshibowotimed”rncatches depicted that “Dega” climatic zone sites Ls and Sb have more mole ratrnpopulation than the “Woina-dega” climatic zone sites An-01 and K. Sb harbored 15rnindividuals per ha while An-01 7 individuals. The male to female sex ratio was 2.1:1.0,rnwhich was statistically significant, but the variation is similar in all sites. Common molernrats preferred open grasslands adjacent to crop fields and extend their foraging tunnels tornnearby crop fields that are not far away. Fertile, well-drained soil and richness of foodrnresources are the main factors for reduction in the length of burrow system ranging fromrn10.2 – 18.6 m. Although the animal minimizes expenditure of energy for burrowing inrnareas of food resources, the bolthole is long to protect itself from danger. Loss on Ensetrnplantation is about 12% for the whole district. This is high where the plant requires 5 to 7rnyears to mature for food processing. This loss in such densely populated, with largernfamily size and reduced farmland is high. Devising proper control and sustainablernmanagement on major and economically important rodent pest on Enset is crucial.rnKey Words: Mole Rat, Tachyoryctes splendens, Agricultural fields, pest, Enset,
