The study on the distribution and abundance of rodents was canied out inside and outsidernagricultural areas at Alleltu peasant association fi'om Oct. 2002 to April, 2003. The study wasrnconducted in three live trapping grids inside the wheat, bean and lentil field in agriculturalrnareas. A survey study was also conducted in different habitats outside the cultivated fieldsrnusing live and snap hÂ·aps. During the whole study period, a total of 260 and 61 captures ofrnrodents were made inside and outside the cultivated fields respectively, by Capture MarkrnRecaphlre (CMR) method. A total of321 specimens were h'apped fi'om 3762 trap nights. Thernrodent species were: Maslomys lIalatensis, MilS mahomel alld Arvicallihis abyssillicl/s.rnPopulation size estimate on the live trapping grids was made using minimum number ofrnanimals (MNA) method as the numbers of recaptures were very few to use the StochasticrnJolly- Seber model. Population size fluctuated in the different stages of crops. It reached itsrnpeak when the crops were maturing and declined after harvest. Outside the cultivated field,rnthe snap trapping resulted in zero capture while the live h'apping showed an increase in thernnumber of rodents fi'om March to April.rnBiomass varied in response to fluctuation of population size and differences in abundance ofrneach species in the tln'ee griqs.rnMost of the distribution and abundance of rodents showed significant temporal variation. Thernspatial variation of rodents showed that M Ilalatellsis was the dominant species in therncultivated fields. But, A. abyssilliC/ls was revealed to be in a relatively higher number outsidernthe cultivated field around the bushes.
