Botanical and zoological gardens maintain collections of living plants and animals for public display, education, research and conservation. Botanical gardens may grow plants from around the world, including trees, flowering plants, herbs and rare or threatened species. Their grounds can include glasshouses, themed planting areas, arboretums and specialist collections. Staff may also study plant identification, cultivation and conservation, and share information through labels, guided tours, talks and learning activities. Zoological gardens care for and display animals in managed habitats, with facilities designed to support their welfare and provide opportunities for natural behaviours. Collections may include mammals, birds, reptiles, amphibians, fish and invertebrates. Typical work includes feeding, veterinary care, habitat maintenance, breeding programmes and participation in conservation or research projects.
