Abstract
The estimated population of Rattus tiomanicus in cocoa-coconut plantation presumably in a stable condition varied between 151 and 216 animals/ha (extrapolated from population estimates of 0.74-hectare). The rats were believed to be trap prone; and thus the population size was probably an underestimate. Survival rates between trapping intervals were high (0.5-1.0) Recruitment was mostly via birth and equally divided among sexes. The proportion of potential breeders was comparatively high (65-100) as was the proportion of pregnant and lactating females. A total of 1086 males and 741 females were tagged throughout the study. The mean growth rate of the population varied between the r values 0.2655-0.3643 (except for week 63 after field was accidently poisoned)
