|Use and Trade:||This species is collected in moderate numbers from the wild (Froese and Pauly 2006).|
D. pathirana is threatened by pressure from shade loss and agricultural effluents (Pethiyagoda 1994).
During the past two centuries, nearly all the natural forests in this eco-region have been cleared for tea, rubber, and coconut plantations, rice paddies, and human settlements (WWF 2001).
