A tree collection is a curated assembly of tree species, often gathered for educational, ecological, scientific, or aesthetic purposes. Each tree in the collection may represent a different species, variety, or geographical region, showcasing the diversity of arboreal life. Tree collections are commonly found in botanical gardens, arboreta, parks, or digital databases, and they serve to promote biodiversity conservation, environmental awareness, and appreciation of natural beauty. Carefully labeled and documented, such collections often include both native and exotic species, enabling the study of growth habits, climate adaptability, and ecological interactions.
