James Johnson, MSc
Growing up on one of Georgiaâ€™s oldest farms, James developed a deep appreciation and a never-ending curiosity for the natural world. His Grandfather and Father impressed upon him the practice of good stewardship of the land and the conservation of its natural resources, and this wisdom guided him into his current field of work in environmental conservation.
James graduated with honors from Armstrong Atlantic State University (AASU) in Savannah, Georgia with a degree in biology. While at AASU he worked as a biological research assistant on a project aimed at better understanding the metabolic pathways of epiphytic Bromeliads. James then came to South Florida in 2009 to pursue the life of a graduate student at Florida Atlantic University and found himself at home in the environment of the Everglades and the costal landscape.
While at FAU, James was involved in many research endeavors spanning from the peat bogs in northern Alberta, Canada, to the tree islands of the Everglades. He graduated with a masterâ€™s degree in 2012 after completing a thesis titled â€œEstimating the Vulnerability of Everglades Peat to Combustionâ€. During his time in graduate school, James became became very familiar with the Greater Everglades ecosystem and joined the team at ICR in November 2012 as a field biologist to continue the ongoing conservation efforts in South Florida and beyond. In 2014 James moved back to Georgia to begin a Ph.D. program.
Jimmy graduated with honors from the University of Florida with a Bachelors of Science in Environmental Science. He began his research career studying under the guidance of graduate mentor Jenny Schafer in the Mack Ecosystem Ecology Lab. He went on to join the Plant Ecology Lab at Archbold Biological Station where he assisted on a number of research projects including demography of several rare plant populations, effects of fire frequency on scrub habitat, experimental restoration of scrub habitat on reclaimed pasture, and plant community structure and composition of differing scrub management regimes. He then began work at the Michigan Tech Research Institute where he conducted ground-truthing surveys of Great Lakes wetland plant communities and worked to generate a map of both the current and possible future extent under modeled hydrologic scenarios of Phragmites australisem>. Jimmy attended graduate school at Florida Atlantic University where he studied combined legacy impacts of invasive species Melaleuca quinquenervia and management practices on plant communities in the northern Everglades. Jimmy joined IRC in 2014 as a field biologist then as a research associate. He is currently a field botanist on the South Florida Conservation Team at Fairchild Tropical Botanic Garden, where he continues to focus on rare plant conservation and habitat management. He also currently serves on the board of directors for the Florida Exotic Pest Plant Council, of which he is the current chair elect.

Originally from the farmlands of Missouri, Christina grew up with a deep respect for nature but a yearning for the big city life. At the age of 21, she endeavored on a trip to make the dream of big city living a reality and moved to Miami. After 8 years in the field of accounting, she began to miss her connection to nature and decided to return to school to pursue a Bachelorâ€™s of Science in Biology at Florida International University. In 2010, she left accounting for good to fully focus on her new love, botany. Armed with her new found plant knowledge and her reliable accounting skills she was chosen for an internship at Fairchild Tropical Botanic Garden as the Conservation Research/Plant Records Intern in 2011. During the year-long internship she contributed to the floristic and conservation research being conducted here in South Florida and abroad including the Cockpit Country of Jamaica, the Caribbean Basin and Indonesia. She also contributed to the maintenance of plants records for the garden including the integration of the American Orchid Societyâ€™s orchid collection into Fairchildâ€™s Living Collection. After the internship ended and her bachelorâ€™s degree completed, Christina started working for the IRC in 2012 helping to maintain the databases the fuel the many floristic inventories that the IRC has to offer. In addition to database management she also assists in floristic and taxonomic research. With a thirst for knowledge she strives for excellence by continuing her education. She is an ISA Certified Arborist and a Florida Master Naturalist.
Craig van der Heiden, Ph.D.
Originally from Zimbabwe in southern Africa, Craig left behind a successful career in ecotourism and entered graduate school at Florida Atlantic University. In 2005, he completed his Masters degree, which focused on modeling the habitat requirements of reintroduced black rhino in the woodland savannas of Malawi. In 2012, he received his Ph.D. in Integrative Biology from FAU for work on the distribution dynamics of crayfish populations in the Florida Everglades. A versatile and experienced manager of multifaceted projects, Craig brought knowledge of business management and complex logistics as well as the science of conservation biology when he joined as Assistant Director of IRC in 2012.
