By Kevin Deacon and Kristie Ehrhardt Special to the Express Located in California’s Central Valley, the Sacramento National Wildlife Refuge Complex is made up of six individual National Wildlife Refuges (NWR) including: Sacramento, Colusa, Delevan, Butte Sink, Sutter and a long stretch of the Sacramento River from Red Bluff south to Princeton, California. The complex adds up to 10,819 acres and was originally established by Franklin D. Roosevelt on Feb. 27, 1937 as a Migratory Waterfowl Refuge. Waterfowl using the Pacific Flyway to migrate currently and historically used the area as a winter refuge. In the mid 1800s, when early settlers were trying to homestead in the Sacramento area, they were met with some inconveniences. It was hot and dry in the summer months and during the winter months the land became a marsh. In order to build their communities and grow food, they developed the Glen-Colusa Irrigation District to divert water from the overflowing Sacramento River and direct it where it could be used for farming. As a result of this and other irrigation projects in California, the acreage of wetlands available to migrating waterfowl was decreased by 90 percent. In the Sacramento region alone, wetland acreage dwindled from 5 million acres to less than 320,000 acres. Although acres of natural wetlands were converted to agriculture, rice farming practices still provided food for the hungry and tired migrating birds. In fact, the throngs of hungry birds could eat up a devastating 40 acres of rice crops in a single night. In response to the conversion of wetlands and the destruction of crops, the Sacramento National Wildlife Refuge (SNWR or Sacramento NWR) Complex was created. The establishment of the complex helped to: • Manage wetlands specifically for wildlife and other plants and animals. • Deter rice crop depredation. • Create endangered species habitat. • Provide recreational and environmental education/interpretation opportunities. • Provide research opportunities. As a result of rice crop devastation, a cooperative rice farming program was established but later failed. As a result, it was decided that all crops should be removed from the SNWR and replaced with managed wetlands. As the water draws down in the spring, seed producing plants germinate and provide food for wintering waterfowl and other wildlife. Today, the Sacramento National Wildlife Refuge is home to more than 400 species of plants, 300 species of birds and 500 different species of mammals, reptiles and amphibians. The Sacramento NWR has the greatest concentration of waterfowl per acre in the entire world, and comprises more than 7,500 acres of managed wetlands, supporting peak populations of 850,000 migrating waterfowl. Other species of interest observed in the complex include bald eagles, red-tailed hawks, great blue herons and snowy egrets, just to name a few. It is an amazing experience to see such an array of birds in such a small area. The NWR headquarters are located at the Sacramento NWR. Here you can learn more about the plants, birds and animals around you. When it is open to the public, they have educational classes for children, youth and adults of all ages. The California Junior Duck Stamp competition is a favorite program allowing youth a chance to create and compete in state and national duck stamp competitions. The SNWR is practically in our backyard, I recommend visiting it to anyone who would like to get out and explore nature; you don’t even have to get out of your car.
