Year Published: 2012
Date Assessed: 2011-07-22
Assessor(s): Allen, D.
Reviewer(s): Ng, H.H. & Smith, K.
Contributor(s): Jenkins, A., Kullander, F.F. & Tan, H.H.
Justification:
Although this species is known to be impacted by loss of habitat (thick forest cover associated with streams and freshwater swamps), it is assessed as Least Concern due to its wide distribution and the lack of empirical evidence of population decline.  More research on the effects of habitat loss on the population are needed and it may be necessary to reassess this species once additional data in this regard is available.
History:
2009 Least Concern
