Caly lives on top of a mountain in Hawai’i. Its species, Cyanea calycina, can’t be found anywhere else in the world. It is critically endangered and faces extinction.

Most will never reach Caly’s remote Hawaiian forest, but plantCam offers you a real-time window into this wao akua to connect you to Hawaii's rare and endangered flora. Invasive species and climate change continuously threaten Caly’s survival. PlantCam collects and visualizes data in real-time to show how environmental variability influences the growth of native plants and guide conservation efforts.
