Accumulated counts for most of Manitoba and Saskatchewan have been below 300 per trap so far, although numbers picked up considerably in the past week in a few locations. At this time, only one Saskatchewan site has exceeded the lowest level of risk (>300). And only one Manitoba site has more than 300 (Altamont at 312) as of this week.
