Audubon opens Rainey Sanctuary in Perry, LA and Theodore Roosevelt Sanctuary in Long Island, NY. Paul J. Rainey Santuary is a 26,000-acre waterfowl hunting preserve, donated by Grace Rainey Rogers. Theodore Roosevelt Sanctuary was donated by Emlen and Christine Roosevelt to honor their cousin, the "conservation president". |

Audubon Nature Camp opens in Hog Island, Maine. Hog Island is named for one of the livestock that roamed its new-world pasture, and later on also becomes home to Project Puffin, an Audubon Seabird Restoration Project that includes the monitoring of other species, including terns, cormorants and murres. |
| 1947: |
Everglades National Park is established. This 1,200 square mile area is part of a 14,000 square mile watershed from central Florida to the sea. In the 1960s the park was threatened again when water was diverted for farming and urban use, and Audubon initiated another long battle to preserve the Everglades. As we enter our second century, Audubon remains actively involved in restoration of the Everglades. |

Audubon’s Corkscrew Swamp Sanctuary opens in Naples, FL. This 11,000+ acres of land boasts the largest remaining stand of virgin bald cypress trees in the world, as well as almost 200 species of birds, viewable from the numerous eco-friendly boardwalks. |
| 1974: |
Lillian Annette Rowe Bird Sanctuary opens. This sanctuary is dedicated to the conservation of Sandhill Cranes, Whooping Cranes and other migratory birds, and their habitat along the Platte River in south central Nebraska. Owned and managed by the National Audubon Society, the original purchase of 782 acres in 1974, which was funded by Lillian Annette Rowe, included 2.5 miles of river channel, wet meadows, and some agricultural fields. Additional land acquisitions have increased the current size of the sanctuary to 1,248 acres. With the addition of the newly constructed Iain Nicolson Audubon Center, located on the banks of the Platte River, year-round education opportunities exist for local schools and the general public. |

Audubon’s Tenmile Creek Sanctuary in Oregon Protected. This sanctuary is the last intact temperate rainforest in lower 48 states, abundant with old growth cedar and sitka spruce. It is also home to the threatened and endangered Marbled Murrelet and Spotted Owl. |

San Francisco Bay restoration takes a major step forward. Audubon is a key player in successfully negotiating California's acquisition of 16,500 acres of Bay Area salt ponds from Cargill, Inc. The salt ponds will be returned to their natural state as healthy wetlands as part of an initiative to restore the entire San Francisco Bay estuary, including 100,000 acres of wetland habitat. |

| 2003: |
Audubon and other conservation organizations fight to protect Arctic National Wildlife Refuge from oil and gas drilling. The U.S. House of Representatives was unable to muster enough support to attach a provision to open the Arctic National Wildlife Refuge to drilling in the "slimmed down" version of their energy bill. In 2005, the threat continues to grow. |
| 2005: |
Audubon's campaign to restore habitat along the Upper Mississippi River celebrates a victory. The Bush Administration requests full funding of $34 million for environmental management of the Upper Mississippi in the 2006 budget. |
