Jungle

A jungle is a dense forest found in hot and tropical climates on planets.
Without its weather modification network, Risa is a geologically unstable jungle with a high amount of precipitation. (DS9: "Let He Who Is Without Sin...")
Carraya IV has a jungle, which is home to the arboreal needle snake. (TNG: "Birthright, Part I", "Birthright, Part II")
Soukara has a large jungle near its Dominion base. In 2374, Worf and Jadzia Dax arranged to meet Lasaran in the jungle. They began to make their way through, until Jadzia was injured in a Jem'Hadar attack. Worf later left Jadzia behind to continue, but changed his mind and returned to her. (DS9: "Change of Heart")
Goralis III had a jungle, which Worf and Ezri Dax crashed into in 2375. Worf later caught an animal in it. (DS9: "Penumbra")
