In celebration of Graduate Student Appreciation Week, Ian Talty, a graduate student at UF/IFAS CAIP, reflects on his ongoing research and quest for effective cogongrass management.
I started my early career in land management, where I experienced first-hand the monumental and often discouraging issues in dealing with invasive plants. When I began my master’s program in 2024, I sought to conduct practical research that could drive progress towards invasive plant management. I found Dr. Stephen Enloe at the UF/IFAS Center for Aquatic and Invasive Plants (CAIP) directly in line with these priorities. As a graduate student in his lab, I have been fortunate to have been able to conduct applied, data-driven research.
Cogongrass (Imperata cylindrica) is a well-known and challenging invasive species throughout the Southeast United States since its introduction in the early 1900s. Cogongrass can have detrimental impacts to Florida’s beloved natural areas, including loss of native biodiversity and changes to fire regimes. This invasive plant is notably challenging for natural resource professionals. Its hearty rhizome production and ability to thrive in a wide range of environmental conditions causes it to persist under active management.
Understanding Cogongrass Management
The goal for my research is to provide a deeper understanding of cogongrass in Florida in three ways. Firstly, we are currently conducting field trials to evaluate alternative chemical control options. Secondly, we are also conducting greenhouse trials that expose plants to various water levels and time periods. This will help us understand how cogongrass responds to different hydrologic conditions. Finally, we are focusing on optimal timing for management strategies specific to Southwest Florida’s unique sub-tropical climate. As this project continues, I look forward to gaining a deeper understanding of this invasive species. Ultimately, providing guidance for more effective cogongrass management strategies.
