Health and nutrition are closely linked in a malnutrition-infection cycle in which diseases contribute to malnutrition, and malnutrition makes an individual more susceptible to disease.

If the body's metabolism is altered the greater the risk is of malnutrition.
Located entirely within Del Norte and Humboldt Counties, the four parks, together, protect 45% of all remaining coast redwood (Sequoia sempervirens) old-growth forests, totaling at least 38,982 acres (157.75 km2).

In addition to the redwood forests, the parks preserve other indigenous flora, fauna, grassland prairie, cultural resources, portions of rivers and other streams, and 37 miles (60 km) of pristine coastline.
