In the past, sportsmen were allowed to perform maintenance on public duck blinds and existing waterfowl holes on three WMAs, including St. Francis Sunken Lands WMA, in northeastern Arkansas. Due to past violations, that routine will no longer be allowed by the AGFC. Violations have included the illegal use of herbicides and excessive clearing of existing waterfowl openings. Another concern is the possible degradation of habitat by ATVs due to flooding this spring and summer. Enforcement officers will be monitoring all state-owned waterfowl areas to ensure compliance.
