A

Question 4

Compare the practices of shelterwood cutting, clearcutting, and seed-tree cutting.

Revolt · Accepted Answer

Clearcutting removes every tree in an area at once, which is highly disruptive. Shelterwood cutting removes trees gradually in stages, leaving mature trees to shelter seedlings. Seed-tree cutting leaves only a few scattered mature trees to provide seeds for new growth before eventual removal.

Question 5

Explain how the destruction of forests affects atmospheric levels of carbon.

Revolt · Accepted Answer

Forest destruction releases stored carbon into the atmosphere via burning or decomposition. It also reduces photosynthesis, which lowers CO2 absorption and increases net atmospheric carbon levels.

Question 6

Removing a specific group of trees within a small area over a long period of time is _______. a. clearcutting b. seed tree cutting c. group selection d. single tree selection Please select the best answer from the choices provided

Revolt · Accepted Answer

Revolt · Accepted Answer

C

Question 8

Explain how a forester can make sure that an area is harvested sustainably.

Revolt · Accepted Answer

A forester ensures sustainable harvest by selecting appropriate cutting methods (e.g., selective or shelterwood), monitoring growth rates, leaving seed trees or shelter trees, planning reforestation, and complying with harvest limits and environmental regulations.

Question 9

List the main responsibilities of a forester.

Revolt · Accepted Answer

Foresters manage forests sustainably by planning timber harvests, protecting against pests/disease/fire, overseeing reforestation, maintaining biodiversity, and ensuring ecosystem health.

Question 10

Compare group selection to single-tree selection.

Revolt · Accepted Answer

Group selection harvests clusters of trees to create small openings that mimic natural gaps and allow shade-intolerant species to grow. Single-tree selection removes individual mature or diseased trees scattered throughout the stand, maintaining a more continuous canopy cover and favoring shade-tolerant species.
