Question 1

What terrain is soil displacement worst in?

What’s the risk based on?

Answer 1

Worst in complex terrain due to skid road const.

• Slope Gradient • Slope Complexity - broken terrain?
• Subsoil Conditions - depth • Organic Soil - high

Question 2

What is surface erosion hazard based on?

Answer 2

• Climate (rain intensity, snowmelt)
• Topography (slope gradient, length, uniformity)
• Soil Properties (texture, structure, coarse fragments, water restricting layer)

Question 3

Risk of FF displacement worst in

Answer 3

Steep hummocky terrain with thin LFH and ah

Risk is based on:

• LFH, Ah depth • Soil texture, coarse fragments
• Depth to unfavourable substrate • Slope Gradient

Question 4

How do we assess for compaction?

What are the risks based on?

Answer 4

Assess for the dominant soil texture and coarse fragment content in the upper 30 cm of soil

• Texture • Coarse fragment content • Soil moisture • Forest floor H horizon thickness • Organic soils
