Woolly Bully: Estimating the Effect of an Invasive Insect on an Area’s Water Cycle
Water is constantly moving throughout the natural environment. Some scientists study the flow of water into, out of, and held within particular natural areas. Trees play a role in the flow of water by absorbing groundwater, releasing water as water vapor through its leaves, and slowing down runoff. In the forests of the southern Appalachian mountains, eastern hemlock trees make up about half the living plant material along mountain streams. However, these trees are being attacked by an invasive species called the hemlock woolly adelgid. Scientists in this article want to know how the flow of water might change near mountain streams if the eastern hemlock trees are killed by the hemlock woolly adelgid.

Note To Educators
The Forest Service's Mission
The Forest Service’s mission is to sustain the health, diversity, and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations. For more than 100 years, our motto has been “caring for the land and serving people.” The Forest Service, an agency of the U.S. Department of Agriculture (USDA), recognizes its responsibility to be engaged in efforts to connect youth to nature and to promote the development of science-based conservation education programs and materials nationwide.
What Is the Natural Inquirer?
Natural Inquirer is a science education resource journal to be used by students in grade 6 and up. Natural Inquirer contains articles describing environmental and natural resource research conducted by Forest Service scientists and their cooperators. These scientific journal articles have been reformatted to meet the needs of middle school students. The articles are easy to understand, are aesthetically pleasing to the eye, contain glossaries, and include hands-on activities. The goal of Natural Inquirer is to stimulate critical reading and thinking about scientific inquiry and investigation while teaching about ecology, the natural environment, and natural resources.
