État de la populationExpert

It is reported as locally abundant, but only in one place (Tropicos.org 2022), and no numerical population information is available. According to the occurrence data, it is suspected that the global population is large, but the current population trend is suspected to be decreasing due to the ongoing threat. Research into population status and trends is therefore recommended.
