ClimateWatch Science Advisor
Eucalyptus camphora is one of the most cold-adjusted Eucalypts and the sugary exudates and flowers are important food sources for Helmeted Honeyeater and lowland Leadbeater’s Possum. In a warming climate we e expect plants to delay emergence until later and start flowering earlier in the year because of climate change warming the Earth. They may also start disappearing in areas, as warmer temperatures suppress growth and development and their ability to renegerate.
Help scientists answer the question: "How are our animals, plants and ecosystems responding to climate change?"
When To Look
Between February and November. Late winter for fallen flower caps. Flowers March to April.
Where To Look
Cold damp slopes, swampy sites and creeksides. Usually grows at higher altitudes.
Looks similar to Eucalyptus camphora subsp. camphora (Broad-leaved Sally). This subspecies will usually have a petiole less than 20mm long. Subsp. humeana will have a petiole 20-30mm long.
