This post was originally going to be about dipterocarps — the most common tree group in the rainforest.
Dipterocarps include both the really tall trees, with buttressed roots if the forest hasn’t been disturbed, and many of those in the lower canopy layers. (Incidentally, the writer of that linked web page hasn’t assumed a pseudonym — I’ve seen his name on some related scientific papers.)
But I came across this video of people actually saving their tropical rainforest. That’s MUCH better.
Here are the world’s red-listed dipterocarps. There are other endangered plants in the rainforest, too.
