Show the ever-increasing water requirements. This requires carefully coordinated management practices that will increase water yield, and simultaneously minimize impacts on or enhance other important resource values. Sixty per- cent of the land needs land treatment and management for erosion control and sediment yield reduction. The 1965 average annual erosion damage was estimated to be $6.7 million. Of this, $3.5 million was from loss in land productivity, $0.2 million was from land lost from streambank erosion and gullies, $1.1 million was damage to improvements and equipment, and $1.9 million was damage to public facilities. Sediment yield is the product of erosion and the efficiency of the streams1 transport ability. The Sediment Yield Map, following page 3^, shows the general location of the four sediment yield classes which occur in the Region. Danger from wildfire on the forest and rangelands usually is present some place in the Region during every month of the year. Problems and responsibilities for wildfire protection and control are multiplying due to the development of small communities, expanding urban, and public use developments scattered throughout the forest and rangelands. The average annual burned area was about ^5,000 acres in 1965* with a resulting damage of $5.7 million. Burned area in chapparal, 33 |
