habitat restoration, invasive species removal


The Linn County Conservation Department has been working hard to restore original habitats in our Natural areas and parks. Part of that restoration has involved the removal of invasive species such as, Oriental Bittersweet, Honey suckle, Autumn Olive, Russian Mulberry, and Brome grass. Once the invasive species are removed the area is reestablished with native vegetation such as prairie grass and wild flowers, which was the dominate native vegetation cover, prior to disturbance by early settlers and the invasion of alien species’.  Iowa was once dominated by prairie, 85% of Iowa nearly 30 million acres was covered in prairie.


One such area is located at Pinicon Ridge Park along the paved trail that runs from Central City through the park.  Conservation Department workers have begun removing invasive species and will be replanting the area to a diverse pollinator friendly prairie mix.  It may look very destructive to some as we are removing many trees and shrubs. However the plants being removed are invasive species or are being smothered and killed by invasive species like Oriental bitter sweet and must be removed to eliminate the invaders. Native trees such as Oak will remain and actually benefit from the reduced competition of the invasives.
