A confirmed tularemia case in a beaver near Babcock prompts Wisconsin DNR to warn anglers not to drink water from streams with beaver activity. Preliminary tests on four Rusk County beavers were inconclusive, with federal lab results pending. Officials urge caution and hygiene, noting transmission can occur via contact with carcasses or contaminated water.

Lake Superior smelt decline worries fisheries balance
Lake Superior smelt and herring populations show opposing trends as smelt drops from 990 million in 1978 to 404 million the next year. UW researchers link shallow-water habitat and predation by coho and chinook salmon to the decline, while herring may recover with adjusted stocking and food-chain management.

Bird watching tips from Wisconsin naturalist Knudsen
DNA chief naturalist George Knudsen says Wisconsin bird watching peaks in April and May during migration. He advises dawn and dusk, forest-field borders, marsh-forest edges, streams and lakeshores, and wind-sheltered spots. Wear drab browns and greens, walk slowly, and emit a high pitched squeak to lure birds and small mammals closer.
