 Most of Tawi-Tawi's forests were cleared by August 1994, and the Sulu bleeding-heart may well be extirpated on the mainland.However, an ethnobiological survey in 1995 generated reports that the bleeding-heart survives and is regularly seen on the nearby islets of Tandubatu, Dundangan, and Baliungan.It was also reported that the species was quite common until the 1970s.
