Current Status
The current overall condition status of the Arroyo Toad Species Indicator is Significant Concern based on three metric conditions. As part of a Declining trend, there were only four HUC12 watersheds (15 sites) occupied by arroyo toad young of the year in 2020 compared to 2008 when 22 HUC12s watersheds were occupied (Metric 1), attributed to an increase in drought as well as aseasonal flows in areas affected by urban runoff (Metric 2). Invasive aquatic species (Metric 3) are of concern as predatory invasive animals are found in eight of the 15 occupied watersheds. Additional metrics will be added as more information becomes available.
