The validity of the assumption that all pellet groups within sample plots are found and aged correctly was tested by checking two game biologists' ability to find and age pellet groups in the field. The biologists differed significantly in their ability to make accurate counts, but both made errors of missing groups and calling new groups old. Observations on the persistence of pellet groups deposited at different times of the year and in different cover types for 5 years, 1953-57, indicated that some pellet groups can persist at least 5 years, with a few appearing similar to new groups even 2 years after being deposited.
