In 1983, the Mattole Restoration Council (MRC) was formed. Their purpose being to combine the restoration efforts with landowners and residents. They issued “Elements of Recovery,” a catalog of prescriptions and erosional sources in 1987. It mapped and categorized areas of tributary drainage and erosional features on the watershed. This project revealed the number of roads, including both active and abandoned roads in the Mattole basin. Techniques and expertise for this project were developed at Redwood National Park. In 1991, MRC’s Douglas fir reforestation project showed a survival rate of 70 to 80 percent. This increased shade, aiding in the hatching of eggs which require a cool temperature.
