1. Natural Limitations and Hazards 



a. Geology 



Lithology - Poorly consolidated materials provide greater potential 



for erosion and sedimentation. 



Structure - Bedrock structures may contribute to sensitivity of 



an area (i.e. dip slopes). 



Geologic hazards - Landslides, slumps, etc. may contribute to 



sensitivity of an area. 



b. Soils 



Erosion potential - Dependent upon soil type, slope, disturbance, 



and other factors. 



Moisture content - Relative to soil stability and capacity for 



forest regeneration. 



Thickness - Relative to soil stability and capacity for forest 



regeneration. 



Fertility - Relative to soil capacity for rapid revegetation and 



forest regeneration. 



c. Topography 



Slope - Steeper slopes are more susceptible to erosion, especially 



impacts from road construction or skidding. 



Aspect - Greatly influences potential for forest regeneration in some 



areas. 



d. Regeneration Potential 



Habitat type - Physical requirements for regeneration will vary 

 among habitat types.
