The purpose of plantCam is to understand how the growth of native plants is influenced by environmental variability and change so we can better conserve these species. Check below some of the data being collected in real-time for Caly and the other native Hawaiian species illustrated below:

Growth of Caly compared to other plant species
The figure below shows growth of a Cyanea calycina stem measured by an automated stem dendrometer (blue line). Also shown are growth measurements of other species (red line). You can select different species from the drop-down menu on the left.
Caly's real-time growth in relation to its environment

The graph below shows short term growth of Caly's stem diameter (blue line) along with simultaneously collected environmental data (red line). Select different environmental variables from the drop-down menu above the graph.

Caly's long term growth
The figure below shows long-term growth of Caly's stem (blue line) along with simultaneously collected environmental data (red line). Select different environmental variables from the drop-down menu above the graph. You can also use the slider below graph to look at a close-up of the data during a particular time period.
Long-term climate variables

Below are graphs showing the long-term climate data we are collecting at the site, with daily values shown. Observe how variable conditions are up there and how the environment changes with the seasons!

The data shown above is preliminary and for demonstration purposes only.
