Earth Day is this Wednesday and the naturalist at the Washington County Conservation board says it's important to keep Iowa's wetlands in mind. Pam Holz says Iowa has lost 90-percent of its wetlands, and last year's flooding was a stern reminder. Holz says they will have an Earth Day scavenger hunt tomorrow (4/18) afternoon from 1:00 to 3:00 at Marr Park for families to learn about Iowa's native wetlands. In case of inclement weather, there will be nature bingo inside the conservation center building. For more information contact the conservation board at 319-657-2400.
