The main threat to the species is habitat loss due to agriculture, wood extraction, and water pollution.

The Copan brook frog (Duellmanohyla soralia) is a species of frog in the family Hylidae found in northeastern Guatemala and northwestern Honduras, specifically in the Sierra del Merendón, Sierra de Omoa, Sierra de Caral, and Sierra Espíritu Santo ranges. The colouring of this species is very distinctive and the specific name soralia comes from the resemblance of its markings to the vegetative structures on some crustose lichens.

The Copan brook frog is a small frog, the males growing to about 32 mm (1.3 in) and the females to 38 mm (1.5 in). The snout is very blunt and the prominent eyes have red irises. The male has a single vocal sac under the throat, with a pair of vocal slits. The dorsal surface is brown with a well-marked pattern of green, olive, and black, pale-edged spots or blotches. The ventral surface is yellow and the outer surface of the fore limb has a patterning of white streaks.

This tree frog is endemic to mountainous parts of northwest Honduras and northeast Guatemala. Its habitat is moist tropical forest and cloud forest at altitudes of up to 1,570 m (5,150 ft) above sea level.
