Hi and welcome to QuestionCove!
As Vocaloid helpfully demonstrated, it is good to include as much relevant information as possible when posting questions, so it is easier for us to help you find your answer.

Now, the description of the area sounds like it is probably referring to a tropical rainforest, based on the presence of taller and shorter trees which have "epiphytes" (nonparasitic plants) growing on them.
Which of the conditions listed would match that of a tropical rainforest (assuming my assumption is correct)?
