ClimateWatch Science Advisor

We expect plants to delay emergence till later and start flowering earlier in the year as a result of climate change warming the Earth. They may also start disappearing in areas, as warmer temperatures suppress growth and development. 

By virtue of their sensitivity to the changes in the climate, epiphytes and orchids provide a forewarning about impending damages and act as bio-indicators.

 

When To Look

Year round. Flowering time October to December.

Where To Look

Epiphytic on mossy branches and trunks in fern gullies of cool rainforest and tall closed forest. Look in fern gullies and gorges and on stream banks in rainforests. Although scattered and uncommon, it can be locally abundant.
