Conservation of Natural Resources in California. 



A hill that has lost its wooded cover, and is therefore losing its soil by erosion. 

 Nothing 1 here to check the floods, or hold back the life-giving water. 



This mountain slope was logged over many years ago. Observe that it does not 

 reproduce forest cover, but remains a bare, parched region, at the mercy of sudden 

 flood and summer heat.
