Worf carries Jadzia through the jungle on Soukara

A jungle is a wilderness of dense overgrowth found on planets. Often in places with a tropical climate.

Without its weather control system, Risa was a geologically unstable jungle with a high amount of precipitation. (DS9: "Let He Who Is Without Sin...")

Carraya IV had a jungle, which was home to the arboreal needle snake. (TNG: "Birthright, Part I", "Birthright, Part II")

Soukara had 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")

A deleted scene from TOS: "Return to Tomorrow" had Spock describe the experience of sharing his consciousness with Christine Chapel as a jungle of illogic.
The scripts of the Star Trek: Deep Space Nine episodes "The Maquis, Part I", "The Maquis, Part II", "The Jem'Hadar", and "Hippocratic Oath" identified the areas seen in those episodes as jungles.
