Green Visions: It's true. One good tern does deserve another.

UMD's Dr. Gerald Niemi has seen a lot of changes in the St. Louis River since he began researching birds and their habitat there in the '70s.

The river was frighteningly polluted 40 years ago, bald eagles were rare in the estuary and piping plovers all but abandoned the area 25 years ago.

Decades later, huge strides have been made in cleaning up the river, there are 4 or 5 pairs of bald eagles nesting in the estuary and efforts have been mobilized to protect nesting habitat for piping plovers.

The work isn't over: Common Tern populations are threatened by a variety of factors including the Ringbilled Gulls that prey on their eggs and chicks in the nesting areas of Interstate Island.  Likewise, the phosphorus we put on lawns is still something that threatens birds and their habitat.

But Niemi is embarking on a fascinating project; he's revisiting and resampling population and habitat  data he originally collected 40 years ago.

Lisa Johnson started her broadcast career anchoring the television news at her high school and spinning country music at KWWK/KOLM Radio in Rochester, Minnesota. She was a reporter and news anchor at KTHI in Fargo, ND (not to mention the host of a children's program called "Lisa's Lane") and a radio reporter and anchor in Moorhead, Bismarck, Wahpeton and Fergus Falls.Since 1991, she has hosted Northland Morning on KUMD. One of the best parts of her job includes "paying it forward" by mentoring upcoming journalists and broadcasters on the student news team that helps produce Northland Morning. She also loves introducing the different people she meets in her job to one another, helping to forge new "community connections" and partnerships.Lisa has amassed a book collection weighing over two tons, and she enjoys reading, photography, volunteering with Animal Allies Humane Society and fantasizing about farmland. She goes to bed at 8pm, long before her daughter, two cats, or three dogs.
