FM Forest Ecology & Silviculture 2

Question 1

Which silvicultural system is BEST suited for shade-tolerant species that require a multi-layered canopy structure?

Accepted Answer

Selection system

Answer

The selection system maintains an uneven-aged stand structure ideal for shade-tolerant species like sugar maple and hemlock that regenerate under canopy cover.

Question 2

What is the primary ecological role of snags (standing dead trees) in forest ecosystems?

Accepted Answer

Providing habitat for cavity-nesting wildlife

Answer

Snags are critical habitat structures providing nesting and roosting sites for woodpeckers, owls, bats, and many other cavity-dependent species.

Question 3

The concept of 'gap dynamics' in forest ecology refers to:

Accepted Answer

Regeneration processes triggered by canopy openings

Answer

Gap dynamics describes how small openings created by tree death initiate regeneration cycles, driving much of the structural diversity in natural forests.

Question 4

Which nutrient cycle is most likely to be disrupted by a stand-replacing wildfire in a Douglas-fir forest?

Accepted Answer

Nitrogen cycle, due to volatilization

Answer

Intense fire volatilizes nitrogen compounds, causing significant losses that can limit forest productivity for years post-fire.

Question 5

A forester observes heavy elk browse pressure preventing conifer regeneration in a clearcut. This is an example of:

Accepted Answer

Biotic interference with regeneration

Answer

Heavy ungulate browse is a biotic (living organism) factor that can suppress or eliminate tree regeneration after harvest.
