Justification | At least 30% of known locations and habitat have been lost to crop cultivation and urban expansion over the past 50 years. Generation length is unknown, so it cannot be listed under criterion A. It persists in at least 40 sites. Determining generation length is a priority conservation action. For now, the species is listed as Least Concern. More field work is required to determine the population size, structure and trends. |
