Lynn Proenza received her B.S. in Environmental Science from the University of South Florida in 2003. For the following eight years, she worked in the private sector including land management and environmental consulting. She then received her master’s degree in Forest Resources and Conservation from the University of Florida in 2012. She has over 21 years of land management and field-based work experience in various environmental fields including 13 years of invasive plant management in both the public and private sectors.

Aimee Cooper completed her BA in 2005 in Life Science with a concentration in Biology at Otterbein College in Westerville, OH. She was employed with the University of Florida between 2005-2016, first with the Center for Aquatic and Invasive Plants providing research assistance for numerous invasive plant species throughout Florida, then becoming the coordinator for the IFAS Assessment of Non-Native Plants in Florida’s Natural Areas (IFAS Assessment), and lastly with Florida Medical Entomology Laboratory (FMEL) examining the efficacy biocontrol organisms for mosquito populations and investigating how non-native bromeliads provide an ideal breeding habitat for mosquitoes. Currently, Aimee is a Senior Environmental Planner for St. Lucie County’s Environmental Resources Department. She assists in protecting the County’s valuable natural resources, sensitive habitats, and wildlife, and also implements the County’s environmental regulations pertaining to vegetation removal, tree mitigation, dune vegetation trimming, wetlands and buffers, coastal zones & shorelines, listed species protection, and landscaping.

Dexter is currently a Research Scientist with the Florida Natural Areas Inventory (FNAI), a research unit within the Florida Resources and Environmental Analysis Center at Florida State University. Since 2017, he primarily conducts invasive plant surveys across the state on Florida’s public conservation areas, including assessments of invasive plant control efforts, and conducting Early Detection-Rapid Response (EDRR) invasive plant surveys. When available, he assists other FNAI staff in conducting vegetation monitoring, natural community mapping, gopher tortoise surveys, Florida Forever site assessments and conservation easement monitoring.

He is active member of the Florida Invasive Species Council, currently serving on the Board of Directors, and he serves on the Plant List and Symposium Planning committees. He also liaisons with several CISMAs throughout the state.

Before joining FNAI, Dexter worked for several years as a biologist for the Florida Forest Service in southwest Florida, managing invasive species on two state forests. He assisted with the recovery of the red-cockaded woodpecker (RCW) on Picayune Strand State Forest by writing burn prescriptions and conducted needed prescribed burns, as well as mechanically managing heavily fuels in RCW recruitment clusters. He was active with the Southwest Florida CISMA during this time, helping plan and hold the Southwest Florida CISMA Annual Invasive Species Symposium. He also staffed a SWF CISMA booth at numerous environmental events in southwest Florida each year.

Dexter has previously worked with a Tallahassee-based environmental consulting firm as well as Tall Timbers Research Station.

Dexter has a Bachelor of Science degree in Biological Sciences from Florida State University, a Master of Science degree in Biology from Georgia Southern University, and a Ph. D. in Biology from the University of Virginia. 

James Leary is the Lead Scientist in the Lake and River Ecosystems Section in the Applied Sciences Bureau at the South Florida Water Management District. He has over 20 combined years of experience on the science and application of tropical and aquatic vegetation management. His mission is to enhance macrophyte communities contributing to the quality and habitat of south Florida’s freshwater systems.

Carl “C.J.” Greene is a Biological Scientist III for the Florida Fish and Wildlife Conservation Commission within the Invasive Plant Management Section and has worked in this capacity for the past 8 years. Mr. Greene is responsible for the management of invasive aquatic plants within the Upper St. Johns River. More specifically, he directs FWC contractors and cooperators for the control of floating plants, creeping water primrose, and any new infestations that may be found. He received his Bachelor of Science from the University of Central Florida in 2001.

Deb Stone is the University of Florida’s Invasive Species Extension Coordinator. She has a long and dedicated history of invasive species and vegetation management in Florida, working with many different organizations across the state- the Florida Park Service, St. Johns River Water Management District, the Nature Conservancy, Hillsborough County and Bok Tower Gardens. She is currently a Doctoral Candidate in Forest Resources and Conservation at UF and received her master’s in the same program in 2017. She is particularly passionate about prioritization, decision support tools, addressing the implementation gap, and fire-invasive plant interactions.

Jenna Cole received her M.Sc. in Wildlife Ecology and Conservation from the University of Florida in 2022. Her primary experience is research and management of Argentine black and white tegus, Burmese pythons, green iguanas, and various other invasive reptilian species throughout South Florida. Currently she is employed as an invasive animal biologist with the South Florida Water Management District assisting in the management of the Python Elimination Program and related invasive species management projects. Jenna’s primary goals are to continue to research and improve management strategies for invasive reptile species.

Alexandra “Alex” Onisko is a Lead Invasive Species Biologist with the South Florida Water Management District, specializing in upland and wetland ecosystems. Alex holds a Master of Science with a major in Agronomy from the University of Florida and a Bachelor of Science with a major in Environmental Studies from the University of Central Florida. She has worked in Land Management and Invasive Plant Management since 2011. Among many other responsibilities, Alex is a technical expert in her field and is responsible for project management, research and development of IPM technologies, and is part of a team leading the aerial monitoring of priority invasive plant species across the Everglades.

Telmah Telmadarrehei received her Ph.D. in Forest Resources from Mississippi State University in 2019. In 2021, she began working as a postdoctoral research associate in the University of Florida Entomology and Nematology Department, specializing in biological control of invasive weeds. Her research focuses on integrating biological control with other pest management strategies to control invasive weeds in the safest and most effective way while minimizing non-target impacts. Currently, she is working on controlling invasive plants such as Brazilian peppertree and earleaf acacia. Passionate about environmental conservation and restoring native species, Telmadarrehei is also actively involved in outreach programs to educate and engage the public on invasive species and classical biological control.

Erick Smith is co-owner of Kestrel Ecological Services. KES focuses primarily on treatment of invasive exotic plants in upland and wetland systems across the state of Florida for private landowners and public agencies. Erick received a B.S. in Forestry from the University of Florida. Previous to founding Kestrel in 2007 he worked in the nursery trade, urban forestry/arboriculture, conservation land management and volunteered for two years at a biological research station in the Ecuadorian Amazon. He is chair of the City of Gainesville Tree Advisory Board and loves to camp, hike and canoe with his partner Jane in Florida and Georgia.
