Report on Florida's St. Johns River is mixed bag

JACKSONVILLE - A new report says development and the spread of non-native wildlife are all increasing strains on the health of the St. Johns River, which runs through north Florida.

The report released Friday by researchers from Jacksonville University, the University of North Florida and Florida Southern College in Lakeland was a mixed bag.

The report says that some changes are helping the river, such as lower levels in some areas of a chemical that feeds algae blooms.
