Scientists in the Institute of Systematic Botany (ISB) study the origins, patterns, and conservation of plant and fungal diversity. Expertise in the Institute of Systematic Botany spans from fungi, lichens, algae, and mosses to ferns and flowering plants. ISB researchers are working on projects in the Americas and in Asia, in tropical and temperate habitats. Regional projects focus on documenting and describing the floras many regions, including the Amazon, the Brazilian Atlantic forest, the Caribbean, and North America. Data generated by curators in the Institute of Systematic Botany provide a critical basis for conservation assessments.
