Supertrees are vertical gardens. These are filled with ferns, bromeliads, and other exotic species. They’re designed to replicate environmental niches, to preserve species from around the world.
The entire project is pretty interesting. Sponsored and funded by the government of Singapore, it shows remarkable foresight (Note: I live in a country where some state planning agencies with hundreds of miles of coastline to manage are not legally allowed to take the effects of global climate change into effect, so the “remarkable” bar may be set pretty low for me).
