Seventh Grade Tree Study at the CVNP

Seventh Grade Tree Study at the CVNP
Posted on 10/18/2019
Last year NIHF STEM 6th graders conducted soil testing for the Cuyahoga Valley National Park. This year we continued our scientific work by trying to help the park rangers get rid of voles. To explain what voles are, they are small rodents, similar to a hamster with a long tail. They eat roots, bark, and seeds. They are roughly 2 to 6 inches long. When the voles eat the roots, the trees fall over and die because they are not healthy enough to survive. We don´t want to hurt the voles, because they are part of the national park too. So we researched solutions and found several ways to stop the voles from eating the roots and the bark so the trees can survive. We think the best solutions are the use of mint, castor oil, disks, and garlic around the trees. We also tried coffee and wire mesh. We planted trees on October 17th and several groups presented their ideas to the CVNP park rangers. We will go back to the park in May to observe the trees we planted and see which ones survived the winter. Written by Isabelle Strobel
