American botany is the study of plant life in the United States, focusing on the diverse flora found across various ecosystems. This field encompasses the identification, classification, and ecological roles of plants, including trees, shrubs, and wildflowers. Researchers often explore the relationships between plants and their environments, contributing to conservation efforts and understanding biodiversity. Key figures in American botany include John Muir, a naturalist who advocated for the preservation of wilderness, and George Washington Carver, known for his work with crop rotation and sustainable agriculture. The study of American botany also supports agriculture, horticulture, and environmental science.
