Crews cut down about 420 ash trees in Pettibone Park and about 100 more on Barron Island in the City of La Crosse to avoid infection from the emerald ash borer.
Crews are now moving to Forest Hills where cutting will continue on Monday. They're clearing out the landscape at the park but the city says it's something that has to be done.
"This is going green and making something out of a bad, making lemons out of lemonade, to sell this wood as a green product rather than just disposing of it to burn in a huge pile or taking up landfill space," said City of La Crosse Parks Superintendent Gar Amunson.
The city is spending about $80,000 to cut the trees down, but will make back about $25,000 by selling the wood. They have received a grant to replant some of the trees.
