Koala
The koala is an arboreal marsupial native to eastern Australia that feeds mainly on eucalyptus leaves and carries its young in a pouch.
Eucalyptus: A genus of flowering trees and shrubs native mainly to Australia, many species of which dominate Australian forests. Koalas depend on leaves from selected eucalyptus species for most of their food.
Koala habitat: The forest and woodland environments that provide koalas with food trees, shelter, and places to move and breed. The availability and arrangement of suitable food trees determine where koalas can persist.
Habitat fragmentation: The breaking of continuous habitat into smaller, isolated patches, often through land development or infrastructure. Fragmented forests restrict movement between koala feeding and breeding areas.
Queensland koala population: Koalas living in the Australian state of Queensland, where populations and threats vary across regions. Queensland populations feature prominently in debates over decline and threatened status.
Marsupial: A mammal whose young are born at an early stage of development and continue growing while attached to a teat, usually in a pouch. Koalas belong to this mammal group and raise their young in a pouch.
Koala conservation: The protection and recovery of koala populations through habitat management, research, and threat reduction. Conservation measures address habitat loss, disease, vehicle strikes, and other pressures on koalas.
Chlamydia in koalas: Infection by Chlamydia bacteria in koalas, associated with conditions including conjunctivitis, urinary disease, and infertility. The disease can cause severe illness and reproductive decline in affected populations.
New South Wales koala population: Koalas living in New South Wales, an eastern Australian state with coastal and inland populations. Regional habitat loss and fire affect this state's koalas unevenly.
Arboreal locomotion: Movement adapted for traveling through trees, including climbing, gripping, and balancing on branches. Strong limbs and gripping hands help koalas climb and rest among branches.
Wildlife rehabilitation: The veterinary care and recovery of injured, sick, or orphaned wild animals for possible return to the wild. Rehabilitation centers treat koalas harmed by fires, disease, and collisions.
