Natural Hybrids
Breeding

Question 4

What would be included in the silvical character of a tree?

Answer 4

• Reproduction
• Natural Regen
• Growth rate
• Competition

• Productivity
• Tolerances

Question 5

• drought

Question 6

What are some damaging agents?

Answer 6

• insects
• disease
• fire
• ice-snow-frost
• wind

Question 7

What should we consider when selecting a species?

Answer 7

Ecological factors (requirements of tree)
Management (objectives and goals)-what tree do you want?Amount? Evaluate and rank options (max sustainable yield, crop reliability, feasibility)

Question 8

what does crop reliability and silvicultural feasibility mean? how do they differ?

Answer 8

Crop reliability refers to how likely a crop is to make it to maturity when taking into account potential diseases or detrimental climate effects.

Silvicultural feasibility takes into account the cost of operatiomns and what potential factors could make a project too costly. ex. Deer will destroy certain saplings, what are the management costs of putting up protection.
