The park's defining character emerges from its dramatic topography: sharp ridgelines clad in dense primary and secondary forest, deep river valleys carved through granite bedrock, and an intricate mosaic of forest types responding to sharp elevation gradients and the region's humid subtropical climate. At lower elevations, broadleaf rainforest dominates, rich with epiphytes and dripping with year-round moisture; higher slopes transition into montane cloud forest where mist clings to the canopy and visibility often disappears entirely. This vertical complexity creates distinct ecological niches that support an abundance of forest birds, small and medium-sized mammals adapted to closed-canopy life, amphibians concentrated near streams and seeps, and arboreal reptiles. The park's rivers and streams sustain their own communities of aquatic vertebrates, while insects and arthropods—the true foundation of this ecosystem's food webs—achieve staggering diversity within the leaf litter and lower strata.
