    A new partnership began in October 2021 and supports science and stewardship activities that benefit both parks and their local communities. Over the next five years parks and their communities will collaborate to identify and address their scientific priorities. Projects in the first year will focus on water quality, marine biodiversity, and preservation of night skies.
