Silverstone’s Poison Frog
Due to harvesting of the Silverstone’s poison frog for the pet trade, the population is thought to be decreasing.
Due to harvesting of the Silverstone’s poison frog for the pet trade, the population is thought to be decreasing. Current subpopulations appear to be a small fraction of what they once were, although there is not enough data to determine population size.
In 1979, 26 individuals were recorded with a survey effort of 6 person/days, while in 2006 only eight individuals were observed in 15 person/days. In December 2016 near the town of Divisora, surveys of 9 person-hours encountered one adult, one sub-adult, and several dozen tadpoles in water pools on a trail. This survey was conducted during heavy rainfall so no adult frogs would have been calling, therefore more individuals could have been present but could not be detected.
Surveys between 2004-2010 at the release site for the introduced subpopulation near Tarapoto have never recorded any individuals of this species. The survey effort varied between two to three people with two to five hours of searching each.
