Long-Term Effects of ATV Fords on Invertebrate Community Dynamics

1. Long-Term Effects of ATV Fords on Invertebrate Community Dynamics Kendra Cole Undergraduate Student Biology and Chemistry Tennessee Technological University Cookeville, TN 38505

2. Introduction • Aquatic invertebrates play a large role in stream communities. • Declines among invertebrate populations can lead to overall decline throughout the entire stream community.

3. Summary • Problem: What effect does stream crossing by ATVs have on aquatic invertebrate populations? • Objective: To access the effects of ATV Fords on the surrounding aquatic habitat, particularly on the invertebrate community in the Calf Killer River.

4. Methods and Materials • Chose 4 sites of study: • Upstream (control) • Seldomly used ATV ford • Frequently used ATV ford • Downstream • Used kick nets to collect invertebrates from each site on two different dates. • Preserved specimens in isopropyl solution. • Identified and counted species in lab. • Analyzed data.
