Protecting Natural Habitat
The sand and gravel shores of John Martin Reservoir are among the few remaining nesting areas in the state of Colorado for the federally threatened Piping Plover and the state endangered Interior Least Tern.
Nesting areas may be fenced off to protect active nests and chicks. Disturbing these shore birds or their nesting areas is a violation of state and federal law. Under no circumstances may members of the public enter the areas that are fenced off. Plover and tern nests are very difficult to see, and it is easy to step on and crush eggs and chicks.
For more information visit our "Sharing the Shoreline" webpage, contact the Project Office (719-336-3476), or the State Park's office (719-829-1801).
The wetlands around John Martin Reservoir are also home to the federally threatened Eastern Black Rail. The black rail is a rapidly declining, super secretive marsh bird. These birds require very dense wetland vegetation and extremely shallow water. Black rails are flightless for up to two months each breeding season, while raising chicks, and during their annual molt. This makes these birds very vulnerable to predators, extreme weather, and land management changes. Because these birds are so stealthy, little is known about them. However, research is being conducted at John Martin to learn how to better protect them. Click here to visit our imperiled species webpage to learn more about these birds.
