Which principle of sustainable forestry requires that the rate of timber harvest not exceed the rate of forest regeneration over the long term?
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.
The concept of 'ecological integrity' in forest conservation most directly refers to:
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.
Under the Montreal Process, which criterion specifically addresses the maintenance and conservation of biological diversity in forests?
Answer: Criterion 1
Criterion 1 of the Montreal Process addresses the conservation of biological diversity, encompassing ecosystem, species, and genetic diversity.
A forester applying the 'precautionary principle' in conservation decision-making would:
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.
Which term describes the long-term storage of carbon in forest biomass, soils, and wood products as a climate mitigation strategy?
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.
The 'triad model' of landscape-level forest management divides forestland into three zones. Which combination correctly identifies those zones?
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.
Which landscape connectivity strategy specifically focuses on linking isolated habitat patches to allow species movement across fragmented forests?
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.
