The unique characteristics of equatorial forests, also known as tropical rainforests, include the presence of tall trees that form a continuous canopy (1), high species richness with numerous species coexisting in a limited area (2), and a wide variety of epiphytes that thrive in the humid environment (3). These characteristics result from the warm, wet climate of these forests, which promotes biodiversity and complex ecological interactions, making them one of the most vital ecosystems on Earth. Understanding these features is crucial for UPSC preparation, as they exemplify key ecological principles and biodiversity concepts relevant to environmental conservation and climate studies.
