Climate Change
In the Pacific Northwest, global climate change models indicate that winter and summer temperatures in the region are likely to be warmer, with possibly higher amounts of winter precipitation. Increased summer temperatures can hasten the drying of important breeding ponds leading to declines in recruitment of juveniles to amphibian populations. Changes in climate conditions may also influence factors such as dispersal and migration patterns, timing of breeding, and ability to withstand local microclimate conditions.
