Vines of the largest size, creepers, aroids, and bromeliads and more than 150 orchid species are part of the epiphytic realm that grows over the giant trees.
Regular monitoring is proposed of hunting, the extraction of timber and non-timber forest products, all forms of encroachment, river degradation, plant-collecting of aroids and orchids, and research.
Ornamental plant collecting, especially for the orchids (Phalaenopsis amabilis and Paphiopedilum argus), pitcher plants (Nepenthes spp.), palms (Veitchia merrillii), and aroids (Amorphophallus spp. and Alocasia spp.) threatens some plant populations.
The peak development of rainforests in the region is as low altitude complex mesophyll vine forests on wet fertile alluvial and basaltic soils where plank buttressing is common, robust woody lianes, vascular epiphytes and palms are typical, and fleshy herbs with wide leaves (e.g. gingers and aroids) are prominent.
Epiphytic ferns, aroids, and bromeliads coat the branches of trees.
Epiphytes are numerous in this montane cloud forest environment and include Aeschynanthus, Agapetes, Rhododendron cuffeanum, various aroids, and the orchid taxa Dendrobium and Pleione.
The beautiful tree-ferns themselves were loaded with other ferns, orchids, and mosses; every fallen tree was draped with fresh green forms, every swampy bit was the home of mottled aroids, film ferns, and foliage plants, mostly green and gold, while in some places there were ginger-worts with noble shining leaves fully six feet long.
From the edge of trails creepers lash at the base of trees, and herbaceous heliconias and calatheas give way to broad-leafed aroids that climb into the shadows.
Ten miles to the west, the cloud forests with their elfin vegetation, dangling epiphytes and cascades of orchids, bromeliads, and aroids give way abruptly to rain shadows and forests composed of willow and a dozen species of oak.
Subdued by the vegetation—the broad-leafed aroids and sprays of orchids, the ferns, epiphytic bromeliads, and hanging lycopodiums—the light fell in a golden hue, filling the lower layers of the forest with half-light and faint gray shadows.
