Cairns Botanic Gardens rebuilds orchid collection after weevil infestation

The Cairns Botanic Gardens is rebuilding its orchid collection after a severe infestation by the tiny orchid weevil, Orchidophilus aterrimus. The weevil, which went undetected until significant damage occurred, has devastated many rare plants. Efforts to control the weevil have largely failed, leading to the removal of infested plants. Staff are now focusing on preserving valuable specimens while starting a new collection for public display. Quarantine measures are in place to prevent further infestations. The recovery process is slow, with some orchids taking years to flower. The gardens aim to educate the public about the threats to these plants, including poaching and climate change, which are impacting their natural habitats.
