Read the first 7 Forest Ecology & Silviculture flashcards as text

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

    Answer: Selection system

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

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

    Answer: Providing habitat for cavity-nesting wildlife

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

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

    Answer: Regeneration processes triggered by canopy openings

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

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

    Answer: Nitrogen cycle, due to volatilization

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

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

    Answer: Biotic interference with regeneration

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

  6. In forest succession, which term describes the community of species that can persist indefinitely under current environmental conditions?

    Answer: Climax community

    The climax community represents the theoretical endpoint of succession where the dominant species can reproduce under their own canopy and maintain dominance over time.

  7. What does the term 'rotation age' mean in even-aged silviculture?

    Answer: Planned age at which a stand will be harvested

    Rotation age is the planned period between stand establishment and final harvest, chosen based on management objectives such as maximum volume, value, or financial return.
