Olympic National Park, Washington - livre d'occasion

The National Park Service publishes Coastal Watershed Condition Assessment Reports. These reports review and synthesize information to determine the status of coastal park resources including water quality, habitat condition, invasive species, extractive uses, coastal development, and other issues affecting their condition. The reports also characterize the relative health or status of water resources, identify actual or potential "stressors" upon these systems, and make recommendations for further studies or assessments where needed to fill information gaps to more fully evaluate condition. This is one of those reports.
