SAF Conservation & Sustainability 2 — Questions and Answers
Question 1: Which principle of sustainable forestry requires that the rate of timber harvest not exceed the rate of forest regeneration over the long term?
- Maximum sustained yield
- Non-declining even flow (Correct answer)
- Allowable cut effect
- Rotation age principle
Correct answer: Non-declining even flow
Non-declining even flow (NDEF) is the NFMA requirement that timber harvest levels must not exceed the long-term sustained yield capacity of the land.
Question 2: The concept of 'ecological integrity' in forest conservation most directly refers to:
- The economic value of forest ecosystem services
- The capacity of an ecosystem to maintain its characteristic structure, function, and composition (Correct answer)
- The proportion of old-growth retained after harvest
- Legal protections afforded to wilderness areas
Correct answer: The capacity of an ecosystem to maintain its characteristic structure, function, and composition
Ecological integrity refers to an ecosystem's ability to maintain its native biodiversity, processes, and resilience without significant human-caused impairment.
Question 3: Under the Montreal Process, which criterion specifically addresses the maintenance and conservation of biological diversity in forests?
- Criterion 1 (Correct answer)
- Criterion 3
- Criterion 5
- Criterion 7
Correct answer: Criterion 1
Criterion 1 of the Montreal Process addresses the conservation of biological diversity, encompassing ecosystem, species, and genetic diversity.
Question 4: A forester applying the 'precautionary principle' in conservation decision-making would:
- Delay conservation action until peer-reviewed data confirms the threat
- Take preventive measures when scientific uncertainty exists about potential harm (Correct answer)
- Prioritize economic benefits when ecological risks are unclear
- Defer all management decisions to regulatory agencies
Correct answer: Take preventive measures when scientific uncertainty exists about potential harm
The precautionary principle holds that when an action risks harm to the environment, precautionary measures should be taken even without complete scientific certainty.
Question 5: Which term describes the long-term storage of carbon in forest biomass, soils, and wood products as a climate mitigation strategy?
- Carbon sequestration (Correct answer)
- Carbon trading
- Biomass energy offset
- Albedo forcing
Correct answer: Carbon sequestration
Carbon sequestration is the process by which forests capture atmospheric CO₂ and store it in biomass, deadwood, litter, and soil over long periods.
Question 6: The 'triad model' of landscape-level forest management divides forestland into three zones. Which combination correctly identifies those zones?
- Wilderness, buffer zones, and urban forests
- Intensive production forests, extensive multi-use forests, and ecological reserves (Correct answer)
- Riparian buffers, upland production, and recreational corridors
- Old-growth, second-growth, and plantation forests
Correct answer: Intensive production forests, extensive multi-use forests, and ecological reserves
The triad model allocates land among intensive timber production zones, extensive multi-use management zones, and strictly protected ecological reserves.
Question 7: Which landscape connectivity strategy specifically focuses on linking isolated habitat patches to allow species movement across fragmented forests?
- Edge effect management
- Wildlife corridors (Correct answer)
- Clearcut rotation scheduling
- Stand-level silviculture
Correct answer: Wildlife corridors
Wildlife corridors are strips or networks of habitat that link fragmented patches, enabling species movement, gene flow, and recolonization of disturbed areas.
