National Wildlife Refuges
U. S Fish & Wildlife Service
At this point, I do not aim to be as comprehensive in my coverage of these public lands as I aim to be with America's national parks, monuments, and other NPS units, but there are interesting issues and amazing places out there that need to be shared.
These pages may be a bit sparser, for now, than the pages for other lands. There is only one of me and there is only so much I can do!
From Wikipedia:
As of 2012, there are 556 National Wildlife Refuges in the United States, with the addition of the Everglades Headwaters National Wildlife Refuge and Conservation Area.
