In Redwood forests, trees condense fog into precipitation and provide necessary water to forest species during dry summers. Recently, researchers have found that the number of foggy days along the Northern California coast has declined by 24 percent, likely due at least in part to climate change. With less fog, the forest ecosystem will have less water to sustain it through dry summers.
More climate impacts:
• Reduced fog and generally warmer and drier conditions could increase risk of fire in the region.
• Rivers that run through the park provide critical salmon habitat, but flooding during the winter or spring could disturb salmon eggs and fry. Warm water and low river flow in the summer could be fatal to salmon as they migrate.
