The upper canopy of Sinharaja primary rainforest (reaching heights over 45 meters) forms an aerial ecosystem supporting hundreds of epiphytic orchid species, aroids, and bird's-nest ferns (Asplenium nidus). Epiphytes do not parasitize host trees; instead, their specialized velamen root tissues absorb atmospheric moisture and mist directly from the frequent cloud-immersion events that sweep across mountain ridges. Accumulated decaying leaf litter and organic humus caught in branch forks provide nutrient substrate for epiphytic root development.
Emergent tree crowns experience intense solar radiation and high wind exposure, contrasting sharply with the deep shade of the understory floor below.
Canopy flowering events trigger foraging activity among endemic birds like the Sri Lanka Hanging Parrot and various sunbird species.
