Research Highlight

Invasive Species Terminology

Dr. Stephen Enloe, Associate Professor at UF/IFAS CAIP, along with many other experts from the UF/IFAS Invasive Species Council developed a definition list for terminology related to invasive species. The group saw a need for consistency in language and took the initiative to take action to make the language clear for industry professionals and other stakeholders.

The excessive number of terms associated with invasive species, and their often incorrect usage, hinders stakeholder education about the threats of invasive species. The terms we propose will increase understanding, thereby promoting behavior changes aimed at limiting the negative impacts of invasive species.

Graduate Student Highlight

Taylor Darnell, UF/IFAS Agronomy Graduate Student

Taylor Darnell is a first year agronomy master’s student studying applied aquatic weed management. As a graduate assistant, Taylor works with the UF/IFAS Center for Aquatic and Invasive Plants (CAIP) where he is currently planning and establishing Hydrilla verticillata, hydrilla tuber management studies for his thesis and several chemical trials for various suppliers. He is co-advised by Dr. Candice Prince and Dr. Benjamin Sperry.

Education & Outreach

Streaming Science Electronic Field Trips

In the Fall of 2020 UF/IFAS CAIP faculty and staff partnered with Streaming Science to host "Beautiful Invaders: Invasive Plants and Our Planet", an electronic field trip (EFT) series. Dr. James Leary, Kelli Gladding and Lara Colley all hosted one of the EFTs, giving K-12 students a very invasive experience. From ecology to impacts to drone technology, the CAIP was able to introduce students to the wide array of facets associated with invasive plants in Florida.

Master Naturalist Program: Invasive Plants of Florida

This course will educate participants in all aspects of invasive plants in Florida. People who complete this course will be able to identify important invasive plant species, understand the threats they pose and how to reduce them through prevention and control, and be prepared to teach others about invasive plants and how to limit their introduction and spread.

Wild Weed Warriors

Getting the word out about invasive plants to the general public can be challenging. Getting people excited about volunteering to remove invasive plants can be even more difficult. In an effort to generate enthusiasm for invasive plant removal, the Education Initiative has formed a volunteer-based club, The Wild Weed Warriors. This conservation task force meets every other Sunday in one of the wooded trails on the University of Florida’s picturesque campus. The Warriors spend two hours removing invasive plants, making friends and learning about the plants that plague Florida’s natural areas. So far, the group has removed over 1,000 pounds of Caesar’s weed, coral ardisia and tradescantia. To learn more, email laracolley@ufl.edu.
