[citation needed] The river is home to various habitat including plant, bird and insect species.

The trail varies between open vistas and dense thickets, but is predominantly open, skirting the ridge-top as it goes along the north side of the river gorge.

Several insects species such as the graphelmis bandukanensis, liparthum, stalk-eyed fly (teleopsis) and myrmarachne mariaelenae also found within the river.
