The Fish Slough Area of Critical Environmental Concern is a protected slough in Inyo County, eastern California. It is located on the western side of the Chalfant Valley, 5 miles (8.0 km) north of Bishop in the northern Owens Valley area.
The Forest Preserve District of Cook County is a governmental commission in Cook County, Illinois, that owns and manages a network of open spaces, containing forest, prairie, wetland, streams, and lakes, that are mostly set aside as natural areas. Cook County contains Chicago, and is the center of the most densely populated urban metropolitan area in the Midwest. The Forest Preserve lands encompass approximately 70,000 acres (280 km2), about 11% of the county, providing open space within its urban surroundings. It contains facilities for recreation, as well as a zoo and a botanic garden.
The South Florida Water Management District (SFWMD) is a regional governmental district that oversees water resources from Orlando to the Florida Keys. The mission of the SFWMD is to manage and protect water resources by balancing and improving water quality, flood control, natural systems and water supply, covering 16 counties in Central and Southern Florida. It is the largest water management district in the state, managing water needs for 7.7 million residents. A key initiative is the restoration of America's Everglades – the largest environmental restoration project in the nation's history. The District is also working to improve the Kissimmee River and its floodplain, Lake Okeechobee and South Florida's coastal estuaries.
The Columbia Slough is a narrow waterway, about 19 miles (31 km) long, in the floodplain of the Columbia River in the U.S. state of Oregon. From its source in the Portland suburb of Fairview, the Columbia Slough meanders west through Gresham and Portland to the Willamette River, about 1 mile (1.6 km) from the Willamette's confluence with the Columbia. It is a remnant of the historic wetlands between the mouths of the Sandy River to the east and the Willamette River to the west. Levees surround much of the main slough as well as many side sloughs, detached sloughs, and nearby lakes. Drainage district employees control water flows with pumps and floodgates. Tidal fluctuations cause reverse flow on the lower slough.
Smith and Bybee Wetlands Natural Area is a public park and nature reserve between the Columbia Slough and the Columbia River in Portland, Oregon. At about 2,000 acres (810 ha), it is one of the largest urban freshwater wetlands in the United States.

A covered shelter, restrooms, a paved walkway, and a canoe launch lie on the north side of the natural area.
Moss Lake Bog is an 84-acre (34 ha) site containing a 15-acre (6.1 ha) glacial kettle lake located in the town of Caneadea, New York, outside Houghton. Over time, sphagnum moss has grown over the open water, turning it into an acidic bog. It is managed by The Nature Conservancy as part of Moss Lake Preserve, and was declared a National Natural Landmark in 1973.

The tradition of harvesting Wild Rice also known as, Manomin (Ojibwe), occurs in the late summer after the dormant rice beds arise during the summer months and are ripe for harvest come mid-August. Protecting this sacred region of the Great Lakes is pivotal in maintaining traditions for our youth to learn and continue, providing opportunities to harvest food year-round, as well as providing a stable ecosystem that affects the entirety of Lake Superior which correlates directly into the Great Lakes as a whole. The wetland was designated a National Natural Landmark in 1973. On February 2, 2012 it was designated a Ramsar Wetland of International Importance.
