Threats [top]

Major Threat(s):

Human disturbance resulting from logging activity in some parts of its range, which could also lead to habitat loss. Wildfires and human-caused fires also constitute a threat. Drying of water sources and droughts also threaten this species, although it remains unclear if these represent natural environmental changes or are driven by anthropogenic activity.
